Combining sport utility with sports sedan handling and performance, RDX features an innovative 2.3-liter four-cylinder turbocharged engine, Acura's exclusive Super Handling All-Wheel Drive(TM) (SH-AWD(TM)), and is designed to redefine the entry premium SUV segment. This near-production prototype provides an advance preview of the all-new RDX that will go on sale this summer.
The RDX features an all-new 2.3-liter i-VTEC(R) four-cylinder turbocharged engine that generates 240 horsepower and 260 lbs-ft of torque. This is the first application of forced induction technology in Acura history. The revolutionary i-VTEC Turbo technology uses a variable flow turbocharger, which is exclusive to the RDX, and provides dramatic performance benefits while maintaining excellent fuel efficiency. To complement the all-aluminum high-performance engine, the RDX utilizes Acura's steering wheel-mounted paddle shifters to manually operate the 5-speed sequential SportShift(TM) automatic transmission.
The Acura's Super Handling-AWD system is tuned specifically for the new RDX platform. SH-AWD's sophisticated electronic controls automatically distribute torque fore and aft, as well as splitting the rear torque left to right. The result is dramatically enhanced handling, traction and stability during sporty driving as well as in inclement weather. A sophisticated chassis with fully independent front and rear suspension complement the SH-AWD. Vehicle Stability Assist (VSA(R)) combines with large disc brakes and ABS to enhance control.
Acura RDX Prototype
The RDX is built on an all-new global light truck platform. Reflecting Acura's commitment to safety through innovation, the RDX is equipped with the Advanced Compatibility Engineering(TM) (ACE(TM)) body structure and additional state-of-the-art safety features. The ACE structure helps to disperse collision forces over a larger frontal area. The system also helps to provide enhanced protection for vehicle occupants while at the same time increasing compatibility with other vehicles in a frontal collision. Front, side and side curtain airbags, in addition to rollover sensors add an extra measure of safety.
The chiseled exterior styling combines with a generous greenhouse to provide excellent visibility for driving in city traffic or on twisty mountain roads. RDX employs a compact upper body with an aggressively raked belt line, sporty wheel flares and a substantial hood that flows down from the windshield to an aggressive Acura signature five-sided grill. Custom 19-inch alloy wheels give the RDX Prototype an aggressive stance. Dual exhaust tips, HID headlights, and a rear spoiler add to the sporty appearance of the vehicle.
The inside, the RDX combines richly appointed materials with a sporty, driver-oriented cockpit. The center console features an innovative storage system, which allows for hidden and lockable storage of a briefcase or laptop computer. The prototype's interior features an assortment of leading-edge technologies, such as the Acura Navigation System with Voice Recognition(TM), AcuraLink(TM) satellite communication system with real time traffic and HandsFreeLink(TM) wireless telephone interface. A premium Acura/ELS(TM) DVD-Audio system is tuned to deliver rich surround sound to the cabin.
The RDX offers seating for five and a versatile rear cargo hatch allows for easy load-in and storage. The second row seats split and fold flat into the floor, providing ample cargo space for an active, on-the-go lifestyle.
With its permanent all-wheel drive and increased ground clearance, the Audi A4 can handle any road or trail; it also offers driving pleasure - even on unpaved surfaces. Naturally, the Audi A4 allroad quattro features all the innovative technologies which impart to the A4 model line its superiority: a range of powerful and highly energy-efficient engines, Audi drive select (intelligent handling technology), the high-tech S tronic transmission, and innovative communication and assistance systems. The vehicle will be available in early summer at a basic price of 37,100 euros.
The design of the Audi A4 allroad quattro recalls the Audi A4 Avant: crisp lines enclose tastefully curved surfaces and the low roof line establishes a coupé-like silhouette. Striking details re-interpret this model line's sporty elegance. The moon-gray single-frame radiator grille bears vertical chrome strips; an accentuated bumper and large air inlets underscore this vehicle's unique identity. Chrome rings encircle the fog lights. And in the option featuring xenon plus headlights, light-emitting diodes comprise the daytime running lights and taillights. Underneath the front end and tail end, the A4 allroad has a stainless-steel underbody guard.
Interior
Refined touches, uncompromising quality and flawless functionality: the interior of the Audi A4 allroad quattro embodies all the strengths for which Audi is renowned. The cockpit clearly serves the driver. Among the control unit's highlights: the standard electromechanical handbrake - which has replaced the lever on the center console with a button - and the central on-board monitor. A color display complements the concert or symphony sound system, or the MMI navigation system plus; the MMI's offset control unit is housed in the center console.
Customers can choose one of several different trim materials: an exclusive allroad fabric, two types of leather, or an Alcantara/leather combination. The fabric designs are available in two colors and the leather trim in seven colors (two of which feature sporty contrasting stitching). Standard inlays are micrometallic platinum; options include aluminum trigon, natural fine-grain ash, laurel nutmeg, and walnut brown. Carpeting is made of velour; the headlining is star silver, linen beige, or black (optional). Many of the operating controls gleam thanks to their standard aluminum look; the door sill trims bear special allroad logos.
The Engines
Audi will initially offer three different engines for the Audi A4 allroad quattro: a gasoline engine and two diesel engines. All three are turbocharged direct-fuel-injection engines. They command respect due to excellent performance, impressive pulling power, smooth running, and high fuel efficiency. The engines are further bolstered by pioneering technologies arising from Audi's modular efficiency expertise. For example, all three units boast a standard on-board recuperation system, which converts mechanical energy into electrical energy during deceleration.
The Driveline
The 2.0 TDI transmits its power to a six-speed manual transmission. The 3.0 TDI and 2.0 TFSI feature the next generation of Audi's dynamic and very efficient S tronic. This innovative dual-clutch transmission switches extremely smoothly among its seven gears within a few hundredths of a second. S tronic also excels thanks to its high efficiency ratio and a broad spread of the gear ratios. The seven-speed S tronic has a fully automatic mode at the ready: the driver can shift as required, if necessary via shift paddles on the steering wheel.
The differential is in front of the clutch and immediately behind the engine. This technical stroke of genius made it possible to reposition the front axle much closer to the vehicle's front end, in turn allowing for a long wheelbase and an ideal distribution of the axle loads. The benefits include steady straight-line stability, superb ride comfort, and excellent driving dynamics.
The Audi A4 allroad quattro features quattro permanent all-wheel drive as standard equipment. Its purely mechanical center differential favors the rear, distributing power at a 40:60 ratio to the front and rear axle. If necessary, the quattro permanent all-wheel drive can route up to 65 percent to the front or as much as 85 percent toward the tail end.
The Chassis
The width of the Audi A4 allroad quattro lays the foundation for its driving dynamics. The car's track is 1,583 mm (62.32 in.) at the front and 1,574 mm (61.97 in.) at the rear - some 20 mm (0.79 in.) wider, respectively, than the A4 Avant. The body is higher on account of a new chassis with longer springs, which - like the new shock absorbers - combine sportiness with comfort. The standard, 17-inch lightweight alloy wheels are fitted with 225/55 tires. At a diameter of 690 millimeters (27.17 inches), even this standard configuration looks rather imposing. For the time being, Audi is also offering 18-inch wheels.
The chassis in the Audi A4 allroad quattro retains all the advantages which distinguish the A4 model line. Steering is straightforward and responsive. A steering box beneath the wheel conveys the driver's input directly to the wheels. The five-link front suspension and the self-tracking trapezoidal-link rear suspension consist largely of aluminum to reduce unsprung weight. 16-inch brakes with excellent cooling behavior provide for rapid deceleration. It should come as no surprise that the Audi A4 allroad quattro offers sportiness, comfort, and stability - onroad and offroad. After all, it is an A4.
On rough terrain, the Audi A4 allroad quattro relies on a high-tech feature of its Electronic Stabilization Program (ESP): the Offroad Detection (ORD) technology automatically identifies the type of driving surface and adjusts the ESP's control parameters accordingly. When the driver depresses the gas pedal, ESP increases propulsive power by tolerating more wheel spin than otherwise. If necessary, it will override for a time in the interests of safety.
On paved roads, Audi drive select further enhances the joys of driving. This control system automatically and perfectly adapts the personality of the Audi A4 allroad quattro to the driver's preferences. Audi drive select namely evaluates the engine's throttle response, the Servotronic power steering, and S tronic's shift points in automatic mode. The driver can freely switch among three different engine maps: comfortable, standard, and sporty. And MMI navigation plus provides yet another on-board control option, and is individually programmable.
The Audi drive select can be paired with Audi dynamic steering. It consists of a superimposed gear system, and varies the steering ratio as well as steering assistance in a continuously variable manner. Audi drive select functions directly at low speeds and indirectly at high speeds. At the vehicle's cornering limit, the dynamic steering keeps the Audi A4 allroad quattro on course via split-second corrective actions - subsequently obviating extensive ESP intervention.
Audi is presenting a new vehicle concept - the Audi A5 Sportback. The five-door model with the long, flowing rear end unites the best of various vehicle genres: the emotion and elegance of a coupe, the comfort of a sedan and the practicality of a station wagon. The Sportback joins the Audi A5 Coupé and Cabriolet as the third member of the Audi A5 model family.
The interior is spacious, offering uncompromising comfort in all four seats. The large luggage compartment hatch is harmoniously integrated into the long, tapered tail end with the flat C pillars; the spoiler lip underscores the tension-filled character. The luggage compartment volume of 480 liters (16.95 cu ft) nearly matches that of the Audi A4 Avant and increases to 980 liters (34.61 cu ft) with the rear seats folded down. Audi A5 Sportback
The Audi A5 Sportback follows the consistent path of innovative technologies at Audi when it comes to the drivetrain. All of the engines are highly-efficient direct injection models - TDI for the cultivated diesels, FSI for the gasoline engines - and all comply with the Euro 5 emissions standard.
The perfect complement is the Audi drive select vehicle dynamics system, which enables the driver to freely vary the throttle response characteristic, the shifting points of the seven-speed S tronic, and the boost provided by the servotronic steering system, which comes standard (from power outputs of 140 kW (190 hp) upwards). The system is offered as a modular package with at least one of the following three options: sport differential, adaptive shock absorber control or dynamic steering with variable boost.
The Design The front is marked with horizontal lines. The horizontal bars come to the forefront in the single-frame grille, which is framed with a narrow strip of anodized aluminum. Two lateral edges underscore the presence of the single-frame grille and extend over the hood as a powerful V contour.
Audi uses ellipsoidal halogen headlamps in models with engines below 140 kW (190 hp). The xenon plus units standard on the other models are available here as an option. With these headlamps, the daytime running light is provided by light-emitting diodes (LEDs) arranged in an arched strip. The LEDs are characterized by their distinct appearance and particularly low energy consumption. The dynamic cornering light system known as adaptive light is optionally available for all models.
The Audi A5 Sportback's sporty character is also immediately apparent when viewed from the side. The large wheels - 17-inch wheels are standard with sizes up to 20 inches available as options - are framed by a powerful body with a slender window strip. The C pillar runs rearward in a long, elegant wave. The pillar integrates a narrow third side window with an upward pointing tip - a homage to the Audi 100 Coupé S from 1969.
The Body The foundation for the qualities that characterize the Audi A5 Sportback is the high body stiffness, which provides the basis for the precise, sporty handling, the superior ride comfort, the high crash safety and the tranquility on board. Oscillations and vibrations are practically imperceptible to the driver and passengers - including those transmitted through the steering wheel and the seat, which comprise the interface to the vehicle.
Audi uses a wide range of state-of-the-art technologies to build the body-in-white. These include hot-shaped steel sheets, most of which are fabricated in the Ingolstadt plant where the Audi A5 Sportback is produced. The tailored blanks of boron alloy steel are heated to 950 degrees Celsius in a continuous furnace and immediately quenched and shaped in a water-cooled die.
This imparts them with an extremely high tensile strength. You could hang six Audi A5 Sportback cars weighing a total of ten tons from a strip of this material two millimeters (0.08 in) thick and 30 millimeters wide (1.18 in). Hot-shaped steels are very light, and profoundly impact the weight balance. The Audi A5 Sportback 2.0 TFSI weighs only 1,500 kilograms (3,307 lb).
Interior and trunk Thanks to its long wheelbase, the Audi A5 Sportback has a spacious interior in which passengers sitting in all four seats will enjoy plenty of room. The Audi A5 Sportback offers much better leg and shoulder room than the Audi A5 Coupé, its dimensions being only few millimeters short of those of the A4 Sedan. The long doors open wide to afford very easy entry and exit, and the car has a very unique, coupe-specific touch: All four side windows are frameless.
The Audi A5 Sportback is designed as a four-seater. Compared to the A4, the rear seats are mounted slightly lower and somewhat farther forward. An armrest is standard, with two additional cup holders available as options. The front seats are sportily low and sculpted for perfect ergonomics; they can be precisely adjusted and offer perfect control and support. Audi offers a fine array of options, including sport seats with large side bolsters, extendable thigh rests and a four-way power-adjustable lumbar support in addition to fully power-adjustable seats with an optional memory function. The greatest comfort is offered by the climate-controlled comfort seats, in which small fans with an automatic heating function ensure that the driver and passengers neither sweat nor freeze.
Luxurious interior The interior of the Audi A5 Sportback is a treat for the senses. Elegant design touches, perfect ergonomics, high-grade materials and uncompromising craftsmanship impart a harmonious overall impression. Teardrop-shaped chrome frames surround the two large instruments and secondary indicators. The high-mounted, central onboard monitor is standard, as is the three-spoke leather sports steering wheel.
Engines Audi has also consistently turned to innovative technologies for the engines. The Audi A5 Sportback will be available with three TDI and three FSI engines at launch, with three additional engines to follow by mid-2010. All of the engines prove that efficiency and dynamic performance are not mutually exclusive, but rather build on one another. Audi's success in motorsports confirms the power of this philosophy: The R8 FSI and R10 TDI racing cars have recorded eight overall victories in the 24 Hours of Le Mans, the world's most grueling circuit course race. On the road, the TDIs from Audi have been at the forefront of efficiency technology since their introduction 20 years ago. No other power plant can match the ratio of power to low fuel consumption offered by the turbocharged diesel with direct fuel injection.
Energy recovery standard Audi uses its new technologies from the modular efficiency platform in the Audi A5 Sportback. All models are equipped with a recuperation system that makes use of the kinetic energy during deceleration. During the coasting and braking phase, the alternator can convert the kinetic energy into electrical energy that is stored temporarily in the battery. When the five-door coupe accelerates again, the battery feeds the energy back. This improves fuel efficiency by reducing the load on the alternator, which is driven by the engine. Furthermore, all models with a manual transmission are equipped with a gear-change indicator that recommends a gear to the driver for optimal efficiency.
The Chassis The Sportback draws on all of the high-end skills of the Audi A5 series for the chassis as well. The five-door coupe shines with sporty handling, superior stability and good ride comfort. The Audi A5 Sportback turns in quickly and willingly, takes all manner of corners at high speed and with great stability, finding good traction at the exit point of the curve.
There are a number of good reasons for these strong points. Among the most important are the high body stiffness and the balanced distribution of axle load. As in the entire A5 series, the front axle is moved far to the front of the Sportback as well. This was made possible by the unusual arrangement of the powertrain components. The differential, which determines the position of the axis, is mounted directly behind the longitudinally installed engine and thus in front of the clutch or torque converter. The battery was moved to the luggage compartment for better balance.
A lot of technology went into the chassis itself. All major components of the front and rear suspensions are made of aluminum, which greatly reduces the unsprung masses. The front wheels are mounted on a five-link axle that can absorb separately the longitudinal and lateral forces acting upon it. Bearings are stiff in the lateral direction for sporty precision and soft and supple in the longitudinal direction.
The front axle and the engine are fastened to an auxiliary frame that is rigidly bolted to the front section of the car. The high rigidity facilitates the spontaneous generation of steering force. The steering box, mounted low and far forward, transmits the steering commands directly to the wheels.
The Radar and camera: the assistance systems A whole range of innovative assistance systems make driving even more relaxing, more controlled and safer. The adaptive cruise control with the integrated Audi braking guard uses radar technology to maintain the distance to the car in front. The integrated Audi braking guard provides the driver with advance warning of an impending collision and assists with braking. Audi side assist also uses radar to make lane changes safer. Audi lane assist uses a camera to help the driver stay in the lane. The Audi advanced parking system uses the rear-view camera to display the area behind the car on the onboard monitor.
Audi R8 Spyder 5.2 FSI quattro - exceptional performance and breathtaking dynamism coupled with the intense sensations of open-top driving. Its lightweight cloth top opens and closes fully automatically; several body parts are made of a carbon fiber composite material.
The Audi R8 Spyder 5.2 FSI quattro makes a powerful statement. The sculptured lines of the emotion-packed, high-performance sports car are a fascinating and unique interpretation of its dynamism. Unlike the Audi R8 Coupé, the Spyder does not have sideblades behind the doors. The side panels and the large cover over the storage compartment for the cloth top are made of a carbon fiber composite. Two arched cowls, which extend to the spoiler lip and include large, integrated air vents, give the rear of the open-top two-seater a powerful profile.
The electrohydraulic soft top opens and closes in 19 seconds, even while driving at speeds up to 50 km/h (31.07 mph). When opened, it folds like a Z into its storage compartment over the V10 engine. The compartment cover opens and closes automatically. The heated glass window, which is separate from the cloth top, is lowered into the bulkhead. It can be independently raised and lowered at the press of a switch, with the top up or down. An additional net-like wind deflector comes standard and can be latched into the bulkhead behind the seats in two easy steps.
The top, which comprises an outer skin of a leakproof textile fabric and the headliner, is fully compatible with high-speed driving. When driving at moderate speeds with the top up, interior noise levels in the Audi R8 Spyder are barely higher than in the Coupé. The bulkhead includes integrated rollover protection in the form of two strong, spring-tensioned plates. Head/thorax side bags in the backrests protect the passengers in the event of a side impact. Full-size airbags stand at the ready in the event of a head-on collision. In a rear-end collision, the integral head restraint system reduces the risk of whiplash injuries.
Close attention to detail: the design Numerous details demonstrate that the Audi designers put their hearts into the design of the Audi R8 Spyder 5.2 FSI quattro. The air inlets in the nose, which direct air across the three radiators, and the lip of the front skirt are painted high-gloss black. The struts in the broad, low, single-frame grille are finely coated with chrome. The standard full-LED headlights are technical works of art. Their reflectors resemble open mussel shells; the daytime running lights appear to be a homogeneous strip, but actually comprise 24 individual LEDs that form a curve at the lower edge of the headlight.
The full-LED headlights from Audi are unmatched by its international competitors. Light-emitting diodes are used for the low beams, the high beams, the daytime running lights and the turn signals. With a color temperature of 6,000 Kelvin, the LED light is very similar to daylight, making it easier on the eyes when driving at night. Additional strengths include excellent light distribution, long service life and extremely low energy consumption.
The side sills of the Audi R8 Spyder 5.2 FSI quattro are broad and angular. V10 badges on the flanks allude to the power of the engine. A dark surface between the rear lights emphasizes the car's width. The chambers of the lights are colored dark red, with LEDs generating a three-dimensional light pattern. The exhaust system ends in two large, oval tailpipes, and the fully lined underbody ends in an upturned diffuser. The rear spoiler extends automatically at higher speeds.
Interior The open-top two-seater from Audi features a generously spacious interior. The three-spoke leather multifunction sport steering wheel is flattened at the bottom as in a race car, and the low-mounted, electrically adjustable seats guide and support the body perfectly.
Quality of fit and finish is extraordinary and the controls are clear and logical. The standard driver information system includes a lap timer for recording lap times. The instruments and the gear lever knob feature red rings. The pedals, the footrests and the shift paddles of the optional R tronic are in aluminum look. Highlighting the list of standard equipment are a generous full-leather package featuring Fine Nappa leather, an excellent sound system from Bang & Olufsen, a deluxe automatic air conditioning system and heated seats. Six different interior colors are available.
Many additional fine features documents the top status of the Audi R8 Spyder 5.2 FSI quattro. The leather for the seats are colored with pigments that reflect the infrared component of sunlight, which keeps the seats up to 20 degrees Celsius cooler.
Uncompromising power: the engine The Audi R8 Spyder 5.2 FSI quattro, which was developed in cooperation with quattro GmbH, dazzles with uncompromising performance. The V10 engine with the aluminum crankcase, much of which is hand-built, follows in the grand motorsports tradition at Audi. The normally aspirated engine produces 530 Nm (390.91 lb-ft) of torque at 6,500 rpm. Peak output of 386 kW (525 hp) is reached at 8,000 rpm, and the rev limit is not reached until 8,700 rpm. Specific power output is 100.9 hp per liter of displacement; each hp only needs to move 3.3 kilograms (7.28 lb) of weight.
The Audi R8 Spyder 5.2 FSI is also available with an optional automatic six-speed transmission. The R tronic offers a normal and a sport program as well as a fully automatic and a manual mode. The manual mode allows the driver to make lightning-fast gear changes using the joystick on the center tunnel or with the paddles on the steering wheel. The open-air sports car also comes with "Launch Control" - a program that manages engagement of the clutch perfectly to maximize acceleration at start.
The quattro permanent all-wheel drive features a central viscous coupling and distributes power to all four wheels with a heavy rear bias. It works together with the locking differential on the rear axle to provide significantly greater traction, stability, cornering speed and precision. It is the superior technology - in particular for a high-performance sports car.
The dazzling performance: the chassis The Audi R8 Spyder 5.2 FSI quattro has a 2.65-meter (8.69-ft) wheelbase and a 43:57 axle load distribution. Like in a race car, there are double triangular wishbones made of aluminum at all four wheels. The hydraulic rack-and-pinion power steering conveys highly precise road contact. The chassis is tuned for good comfort, thanks in part to standard Audi magnetic ride technology. This uses magnetic fields in the shock absorbers to adjust their response to road conditions within milliseconds and adapt to the driver's style. The driver can choose between two base characteristics. A sports suspension with conventional shock absorbers is available as an option.
The Audi R8 Spyder 5.2 FSI quattro rolls on 19-inch wheels of 10-spoke Y design. The front rims are shod with 235/35 tires, with 295/30 tires at the back. 305/30 tires are optionally available. The brakes offer impressive performance: The four discs are internally ventilated and perforated, with eight-piston calipers up front and four-piston calipers at the back. Optionally available from Audi are oversized carbon fiber-ceramic discs that are extremely lightweight, robust and long-lived. The ESP stabilization system has a Sport mode and can also be completely deactivated. The brake system includes an assist function that facilitates starting on gradients.
Audi is once again producing a five-cylinder engine - and a very special one at that. Arriving at dealerships this summer, the Audi TT RS has a turbocharged 2.5-liter engine with direct gasoline injection; it produces 250 kW (340 bhp) and 450 Nm (331.90 lb.-ft.) of torque. The blazing five-cylinder engine enables the Audi TT RS to perform extraordinary feats. In conjunction with quattro permanent all-wheel drive and a high-performance chassis, the engine makes the compact Audi TT RS a top-notch sports car - available as a coupé or roadster.
Sporty five-cylinder gasoline engines have a long legacy at Audi. The most famous is arguably the turbocharged 2.1-liter engine in the Audi quattro. The first version, which was launched in 1980, offered an impressive 147 kW (200 bhp). And the Audi Sport quattro from 1984, directly inspired by motorsport, delivered a whopping 225 kW (306 bhp). For 25 years, turbochargers and quattro have been a dynamic formula for success.
Audi has resumed using this recipe. Designed from scratch, the five-cylinder engine combines a turbocharger with FSI direct gasoline injection to elevate the Audi TT RS to a high-performance sports car. The TFSI delivers 250 kW (340 bhp) from a displacement of 2,480 cc (151.34 cu in): a specific output of 100.8 kW (137.1 bhp) per liter.
The power-to-weight ratio is also outstanding. In the case of the Coupé, which weighs in at a mere 1,450 kilograms (3,196.70 pounds), the power-to-weight ratio is just 4.3 kilograms per bhp. The Audi TT RS Roadster has a weight of 1,510 kilograms (3,328.98 pounds) and a power-to-weight ratio of 4.4 kilograms per bhp - thanks to its extremely lightweight and largely aluminum body constructed as per the Audi Space Frame principle. Audi TT RS
The Audi TT RS Coupé rockets from 0 to 100 km/h (0 to 62.14 mph) in 4.6 seconds; the Audi TT RS Roadster needs just a tenth of a second longer. The limited top speed of 250 km/h (155.34 mph) is merely the official figure for both versions; as an option, Audi can increase it to 280 km/h (173.98 mph).
Compact and Lightweight: The Five-cylinder TFSI
The ultra-powerful five-cylinder engine is extremely fuel-efficient, requiring an average of just 9.2 liters/100 km [25.57 mpg] as regards the Coupé (Roadster: 9.5 l/100 km [24.76 mpg]). Switchable flaps in the intake manifold mix the incoming air in a calculated configuration. Injected at a pressure as high as 120 bar by the common-rail system, the gasoline swirls intensely in the combustion chamber - which in turn cools the walls. This subsequently facilitates a compression ratio of 10.0:1, which is very high for a turbocharged engine. Both of the adjustable camshafts, controlled via chains, also enhance charging efficiency with respect to the air-fuel mixture.
The large turbocharger generates up to 1.2 bar of boost pressure. The intercooler, fed air ideally by the lower segment of the single frame radiator grille, reduces the temperature of compressed air by over 80 percent at full load.
When an Audi TT RS driver pushes the standard Sport button on the center tunnel, a flap installed in the left exhaust tailpipe renders the exhaust noise even more robust and intense while boosting engine responsiveness. An optional Sport exhaust system is available with matt black tailpipe trims and sound flap.
For Purists: The Driveline
The Audi TT RS is the first classic sports car in the Audi RS family. Like the Audi RS4 and the Audi RS6, the Audi TT RS was developed by quattro GmbH as a pure, no-holds-barred driving machine. A new six-speed manual transmission conveys the engine's tremendous power, and permits easy and precise operation thanks to a specially designed shift lever boasting particularly short shift travel. The transmission's defining characteristics are a high efficiency ratio and a sportily narrow spread of the gear ratios.
The Audi TT RS features quattro permanent all-wheel drive as standard equipment. Its heart lies at the rear axle: an electronically controlled, hydraulic multi-plate clutch. If a situation calls for it, the clutch redirects a majority of the torque input from the front wheels to the rear wheels.
Within milliseconds, a powerful electrical pump in conjunction with an accumulator presses together the clutch's plates via hydraulic pressure. Additions to the quattro powertrain include a constant velocity joint before the propeller shaft and a compact rear-axle differential - both are heavy-duty components.
High-tech Excellence from Audi: Chassis and Body The chassis of the Audi TT RS builds on the cutting-edge foundation of the base Audi TT design. The four-link rear suspension, which handles longitudinal and lateral forces separately, plays a crucial role. The electromechanical steering is highly efficient and the power steering adjusts to the vehicle's speed. With aluminum in the front and sheet steel in the back, the body's innovative mixture of materials results in a well-balanced axle-load distribution, excellent crash safety, and the outstanding rigidity which lays the cornerstone for the car's precise handling.
The Face of Power: The Exterior At just 4.20 meters (13.78 feet) in length, the vigorously compact Audi TT RS hints at its explosive potential from the very first glimpse. The front spoiler tapers downward into a splitter, reminiscent of a racing car. The large and squared air inlets have diamond-shaped inserts. And the high-gloss black single frame grille with a frame in matt aluminum look and the TT RS badge bear the same styling. The xenon plus headlights with LED daytime running lights notify faraway drivers that an Audi TT RS is approaching.
The sides of the vehicle are accentuated by large wheels in 5 twin-spoke design, vigorous side sills, and exterior-mirror casings in matt aluminum look. At the tail end, the two large oval exhaust tailpipes - spaced apart - are encircled by a diffuser insert. Here, too, is a TT RS badge. A stationary rear spoiler is standard, though customers can opt for one which automatically extends and retracts. Thanks to a drag coefficient of just 0.3, the 2+2-seat coupé and the two-seat roadster glide effortlessly through the wind. Audi offers the TT RS in eight colors. Among them are four exclusive options: Daytona Gray, pearl effect; Mugello Blue, pearl effect; Sepang Blue, pearl effect; and Suzuka Gray, metallic. The Audi TT RS Roadster's soft top comes in black or dark gray.
The Interior and Equipment Packages The dynamic exterior of the Audi TT RS is matched by the interior. The leather multifunction sports steering wheel has an especially thick rim, is flat-bottomed, and is covered with perforated leather. Integrated in the instrument panel, the driver information system can display boost pressure and oil temperature as well as a lap timer for chronicling feats at the racetrack. The door handles consist of two slim strips - typical of Audi RS models. An automatic climate-control system and the concert sound system are standard, as are an electrohydraulic soft top and an electric wind deflector for the Audi TT RS Roadster.
The first shake-down has been held at Fiorano of a very special one-off, the Ferrari P540 Superfast Aperta, built for an American client. The car, the second in a new Special Projects programme created by Ferrari to meet requests from the most discerning clients and collectors to create truly unique models, is based on the Ferrari 599 GTB Fiorano and was inspired by a Carrozzeria Fantuzzi-designed Ferrari built specifically for the 1968 Fellini film, Toby Dammit, itself inspired by one of the tales of Edgar Allan Poe.
In accordance with the Special Project's approach to producing such individual one-offs, the Ferrari P540 Superfast Aperta respects all existing international safety and homologation requirements and is thus road legal. The car was designed by Pininfarina and built in Maranello, and the client was directly involved in each stage of its development. As the 599 GTB Fiorano donor car is a coupé, considerable effort went into strengthening the chassis by using finite element analysis in development and the increase in weight was kept down to just 20 kg by employing carbon-fibre extensively.

The Ford Fiesta is the next milestone under the ONE Ford plan to design and develop vehicles that meet the differing needs, wants and expectations of customers around the world. More than 500,000 Fiestas have already sold to customers in Europe and Asia.
When developing the new Fiesta, Ford conducted extensive global customer research. Findings clearly indicated the need for style topped the list of customer desires everywhere in the world. In Europe, across North America and in the Asia Pacific region, customers are looking for a distinctively designed small car that offers world-class quality, convenience, comfort and connectivity.
The anticipated new Ford Fiesta arrives in North America with strong consumer awareness, thanks to the Fiesta Movement program. With 100 social media mavens chronicling their experiences of driving European market Fiestas on American roads, Fiesta has generated more than 675,000 Flickr views and more than 5.5 million YouTube video views.
Kinetics and aesthetics
Kinetic design imparts a sense of movement - even while standing still - harmonizing character elements to reflect global Ford identity, enabling Ford Fiesta to project its own air of confidence, style and individuality. Fiesta targets a youthful "design progressive" mind-set, a consumer group that values style and diversity as worthy assets.
Up front, Ford Fiesta sports the global Ford face, centering the Blue Oval badge on the grille over the signature inverted trapezoid lower grille opening. These subtle cues engender familiarity across the portfolio, providing aesthetic linkage between the distinctive new Ford Taurus, the fuel-efficient midsize Fusion and the bold Fiesta.
Adding eyes to the Ford Fiesta face are sweeping, elongated headlamps that frame and connect the hood to muscular, sculpted front fenders. Available in sporty five-door hatchback or four-door sedan body styles, Ford Fiesta provides ample space for occupants and their gear. The Ford Fiesta design is further enhanced with a choice of nine vivid new colors. From Bright Magenta through Lime Squeeze to Blue Flame, Fiesta's broad color palette - more available colors than any other segment competitors - instills vibrant individuality.
The Inside o Ford Fiesta Ford Fiesta is as dramatic on the inside as it is on the outside. Boldly sculpted surfaces, contrasting colors and comfortable, supportive materials make the interior as individual as the driver.
The instrument panel centerstack - focal point of the new Fiesta interior - was designed to feel as useful and familiar as the keypad on a mobile phone.
The North American Ford Fiesta features first-row bucket seats with a 60/40 split second-row seat. Cloth or leather seating surfaces vary by trim level offering comfort, style and individuality. High series Ford Fiestas also offer leather with sporty contrast accent color piping.
Soft, sculptured surfaces and the centerstack layout provide the Ford Fiesta with a sense of harmony. Intuitive switchgear placement, comfort zone seating and available ambient lighting allow a driver to maximize the mood with seven complementary colors - switchable among three levels of intensity - for interior accent lighting.
Fun, with fuel efficiency Ford Fiesta's flowing sculpted hood covers a 1.6-liter DOHC I-4 engine with an estimated 119 horsepower and 109 ft.-lbs. of torque. Spirited performance and fuel-efficient economy are signature attributes with the Ford Fiesta expected to deliver best-in-class fuel economy at 40 mpg.
Ford Fiesta's advanced 1.6-liter engine features Twin Independent Variable Camshaft Timing (Ti-VCT) allowing the engine to be downsized for fuel economy while continuously optimizing camshaft phasing for throttle response, performance and flexibility. Big results from a small package are possible with several new technologies in this new global engine, including an advanced new front end accessory drive (FEAD) belt with stretchy dynamics to improve the engine's thermal dynamics. The elasticity in this new drive belt eliminates the need for a belt tensioner and contributes to overall fuel economy.
Ford Fiesta features a standard five-speed manual transaxle with gear ratios selected to offer spirited off-the-line performance and exceptional fuel economy for drivers who desire three pedals and a stick shift to maximize driving experience. Specially tuned front struts, bushings, dampers, stabilizer bars and a rear twist-beam axle keep Ford Fiesta sure-footed and firmly planted. Sporty, European driving dynamics prevail.
Automatically game-changing An available all-new North American industry-exclusive PowerShift six-speed automatic transmission combines the responsive performance and fuel economy of a manual transmission with the convenience of a traditional automatic in one advanced, dual dry-clutch package.
Twin internal clutches keep the PowerShift in constant mesh, always optimizing for maximum responsiveness or fuel efficiency, depending on input received from the driver's foot on the accelerator pedal. This "dry" transmission operates with sealed internal lubrication, reducing internal friction and adding to Ford Fiesta fuel economy. The lack of pumps and hoses reduces under-hood complexity, saves weight and also contributes to fuel efficiency. PowerShift has been proven in Ford's European market and will redefine North American small car segment expectations for responsive shifting and fuel efficiency.
Power steering conserves fuel For confidence-inspiring on-road dynamics, Ford Fiesta features Electric Power Assist Steering (EPAS) which reduces complexity while saving weight and fuel. This advanced system is speed-sensitive - providing optimized assist based on speed, cornering forces and acceleration or deceleration. The Ford is aggressively moving to EPAS across its product lineup. The system already is available in several Ford, Lincoln and Mercury nameplates, and by 2013 nearly 90 percent of Ford's lineup will offer this fuel saving technology.
EPAS also includes Pull-Drift Compensation to help Ford Fiesta track true regardless of road crown or side wind conditions. In addition, active nibble control helps detect and compensate for tire balance irregularity. Both features - enabled by EPAS - are class-exclusives.
Strength, safety, quality and quiet More than 50 percent of Ford Fiesta's welded body structure is made from high-strength steel, with ultra-strong boron steel used in several critical areas. This rigid body shell contributes to Fiesta's confident road-holding, best-in-class occupant safety and quiet composure. The Ford Fiesta safety is enhanced by an array of features including dual-stage first-row air bags, a class-exclusive driver's knee air bag, side air bags and side curtain air bags. AdvanceTrac® with ESC (Electronic Stability Control) is standard on Ford Fiesta, along with seat belt pretensioners, rear door child safety locks and a Safety Canopy system.
Tested and proven on virtually every continent where you can drive a car, Ford Fiesta arrives with proven quality and customer readiness.
Fiesta NVH (noise, vibration and harshness) control is taken to a new level of quiet for this segment, helped in part by a specially laminated, class-exclusive windshield that was chosen to help absorb and contain noise. Engine noise is subdued by a hood blanket, with enhanced door seals keeping wind noise minimized. Special padding behind the instrument panel and foam baffles mounted inside the pillars keeps Ford Fiesta quiet. Even the headliner material was specified for its sound-deadening qualities. Much of Ford Fiesta's sound-absorbent materials are comprised of recycled content, helping to conserve resources as it preserves peace and quiet. In addition, Ford Fiesta aerodynamics contributes to both NVH control and fuel efficiency.
The features and functionality
From class-exclusive automatic climate control to a standard aux input, Ford Fiesta offers customers a number of standard and available features that increase convenience and add connectivity. Among them is Ford SYNC, integrating a driver's mobile phone with Fiesta's onboard, voice- activated communications and entertainment system. Ford Fiesta also offers keyless entry and push button start, a feature unique within the segment. Drivers of all sizes can adjust the tilt-and-telescoping steering wheel to suit their individual preferences. Reflecting Ford Fiesta's versatility and adaptability, adjustable cup holders can accommodate Red Bull cans and Big Gulps along with every container size in between.
The Infiniti G37 Coupé offers dramatic performance in a thoroughly seductive shape. Although sharing a great deal of hardware with the Infiniti G37 Sedan, the Coupé is designed to appeal to different buyer.
The dynamic styling allied to its obvious performance potential will appeal to successful individuals who appreciate beautiful design and enjoy driving.
There are three versions of the Infiniti G37 Coupé on offer - the well equipped G37 Coupé, the more luxurious GT version with leather upholstery, and the sport-oriented S version with 4-Wheel Active Steer system, a Viscous Limited Slip Differential (VLSD) and sports suspension settings among other changes.
Exterior styling A long bonnet, short overhangs and dramatically raked roof line give the Infiniti G37 Coupé a silhouette that sets it apart from rival products based more heavily on their saloon counterparts.
Designed as a modern sports car without compromise, the Infiniti G37 Coupé has elegant and sophisticated proportions allied to an expressive, curving shoulder-line to give a feeling of movement even when stationary. The shorter and lower roofline also helps accentuate the Coupé's low centre of gravity and gives a clear indication that this is essentially a rear-wheel-drive car.
Curving 'character' lines at the front of the car mimic the lines of the front wings and help give the Coupé a more athletic and aggressive stance, while the wave-style aluminium bonnet incorporates a natural power dome to accentuate the potency of what lies beneath.
Interior environment The Infiniti G37 Coupé provides a sporting cockpit environment for the driver and a luxuriously open space for its passengers. The dashboard and centre console, complete with seven-inch colour display, adopts Infiniti design DNA with a 'double wave' upper section linked to a central vertical spine for a feeling of solidity. Textured aluminium trim inserts can be found on the centre console, the instrument binnacle and the door panels.
Its gracefully curved door trims have been inspired by traditional Japanese ceremonial swords, while the trim inserts are modelled on Japanese Washi handmade paper. Other signature Infiniti features are the elegant analogue clock on the dashboard and purple backlighting of instruments and controls. Thanks to its long wheelbase, there is room in the rear compartment for two adults with easy ingress and egress provided by the wide opening doors and the electric fold and slide front seats. The practicality and loading capacity of Infiniti G37 Coupé is further improved by the folding rear seats
The Engine and powertrain Infiniti's latest 3.7-litre V6 is a potent, high revving, 24-valve twin cam unit producing 235 kW at 7,000 rpm (320 PS) and an impressive 360 Nm of torque at 5,200 rpm. Constructed from lightweight aluminium, the engine features a two-part bed-plate construction which is more rigid than a single piece casting for reduced vibration levels. It also permits sustained use at higher revs: the V6 is red-lined at 7,500rpm.
The VQ37 unit features VVEL (Variable Valve Event and Lift) technology to optimise efficiency and, in turn, the balance between power, response, fuel efficiency and emissions.
By continually altering valve lift and therefore the quantity of air in the combustion chamber it provides a more powerful combustion phase to increase torque and power. Best of all, as the valves control the intake rather than a conventional butterfly, response to throttle inputs is immediate. VVEL improves fuel economy and lowers emissions compared to standard valve lift systems.
Precise mapping of the ECU, meanwhile, helps the engine provide a progressive 'swell' of power and torque, providing a 'building wave' of acceleration rather than a peaky power delivery.
It delivers a top speed of 250 km/h (155 mph) with 0-100 km/h (0-62 mph) taking 5.8 seconds (on M/T version). Fuel economy over the combined cycle is 10.5 l/100kms (26.9 mpg) while the Coupé has a CO2 figure of 249 g/km. The engine is fully compliant with Euro 5 emission level requirements.
In keeping with the performance profile of the Coupé, Infiniti engineers have developed a special aural soundtrack for the car. Equal length tubular exhaust manifolds and a symmetrical exhaust and silencer system have allowed the engineers to create a linear sound with a good balance between low and high frequency notes.
As well as a smooth shifting six-speed manual transmission, the Infiniti G37 Coupé is available with a new seven-speed automatic option with Adaptive Shift Control (ASC) and magnesium paddle shifters mounted behind the steering wheel.
Chassis and driving dynamics
The Infiniti G37 Coupé uses the second-generation version of Infiniti's FM platform. The 'front midship' engine location sees the compact V6 mounted in the front of the car, but as low and as far back as possible, with most of the block behind the front axle line. The result lowers the centre of gravity and helps to deliver the optimum front to rear weight distribution.
The fully independent suspension uses lightweight aluminium components to reduce weight as much as possible. A double wishbone set up at the front and a subframe-mounted multi-link arrangement at the rear allied to an extremely rigid body shell, gives the Infiniti G37 Coupé agile handling perfectly in keeping with its performance potential.
All versions of Infiniti G37 Coupé come with Electronic Stability Program (ESP), while the power-assisted four-wheel vented disc brakes have a four-channel, four-sensor Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist (BA) as standard.
To enhance the braking feel, the Infiniti G37 Coupé uses a 'link-design' pedal which becomes progressively firmer as g-forces and vehicle speed increases. As a result, the driver has a more direct sensation of the forces acting on the car as he brakes from high speed, as well as the benefit of increased assistance. At lower speeds the brake is easier to operate but with more travel relative to assistance.
The power steering system is a vehicle-speed-sensing type with a twin-orifice structure, which provides optimum steering effort at both high and low vehicle speeds. The sports oriented G37S version has a number of chassis changes in keeping with its sharper profile. The principal enhancement is the addition of the 4-Wheel Active Steer (4WAS) system which helps improve handling performance still further by varying the front steering ratio and adjusting the geometry of the rear suspension according to steering input and vehicle speed. Other standard features of the G37S include a Viscous Limited Slip Differential, recalibrated suspension settings and an enhanced braking system with four piston front brakes and two piston rears.
Standard and optional equipment The Infiniti G37 Coupé has a full complement of user friendly - and above all, useful - standard equipment, plus options for those who want to make even more of a statement. Standard features include the intelligent I-key with smart access and push button starter, a six-disc, seven-speaker audio system with an RCA AUX-in jack socket for MP3 players. Bluetooth phone connectivity and cruise control with speed limiter can all be operated via switches on the leather-trimmed multi-function steering wheel.
Other standard features include power seats (with eight way adjustment on the driver's side and four way for the passenger), aluminium pedals and footrest, auto-dimming rear view mirror, front and rear parking sensors, automatic lights and wipers, 18-inch alloy wheels, six airbags and integrated fog lamps. For the perfect driving position, the binnacle is attached not to the dashboard but to the steering column itself, and moves with the wheel when the latter is adjusted for reach and rake.
The Adaptive Front-light System (AFS) and "Scratch Shield" paint are also standard. Bi-Xenon headlamps are linked to steering inputs and automatically follow the path of the front wheels to provide a wide spread of light around corners and on winding roads. "Scratch Shield" paint incorporates a special highly elastic resin within the conventional clearcoat to increase the paint's flexibility. A car painted with "Scratch Shield" paint can exhibit up to five times fewer scratches that a conventional clearcoat when exposed to the same conditions.
In addition to its chassis and dynamic changes, the G37S adds a sports seat with manual thigh extension for the driver. The seats themselves are upholstered with leather as well as heated and have 14-way power adjustment (driver) and 8-way power adjustment (passenger). There's a tyre pressure monitoring system as standard, plus 19-inch alloy sports wheels.
The major option is the new seven-speed automatic transmission with manual mode and magnesium paddle shifters, enabling drivers to shift the transmission without releasing their hands from the steering wheel. With its additional forward gear, the new automatic transmission has a wider spread of ratios which benefits both fuel consumption and drivability. The seventh speed is effectively an overdrive ratio, returning improved fuel economy on a steady throttle without compromising in-gear flexibility for overtaking. Shift points are tuned to keep the engine in the largest part of the torque curve, ensuring there is always a healthy reserve when the driver wants to overtake. The linked Adaptive Shift Control (ASC) system switches between three different programs depending on input from the major control systems throughout the car.
Other options include Intelligent Cruise Control (ICC) which uses brake, throttle and laser sensors to help maintain a set distance between the Infiniti G37 Coupé and the car in front. In automatic transmission versions, the software reduces driver's workload even more allowing ICC to work from 0km/h to 180 km/h thanks to the "Full Speed Range" feature. An integral part of the ICC option for A/T models, the Intelligent Brake Assist system analyses closing speeds to a vehicle ahead helping reduce damage caused by a rear-end collision. If the driver must take immediate action to avoid a collision, the system sounds a warning to prompt driver action or can even activate the brakes to decelerate the vehicle.
A custom-engineered Bose® sound system sets a new standard for stereo performance in a car. Its 11 high-performance speakers provide crisp musical detail, with impactful low notes bringing G Coupé owners closer to the power and emotion of a live concert performance. To achieve this, Bose® engineers used proprietary digital signal processing and multiple channels of custom equalization to help tune the sound specifically for the vehicle. The Bose® sound system is available as part of a Multimedia pack with also incorporates a DVD navigation system with voice recognition and a rear-view parking camera. Final options include an electric glass sunroof, metallic paint and a temporary spare wheel (replacing standard tyre repair kit), while a subtle African Rosewood trim interior is available on the G37 GT.
The Safety High levels of passive safety were a priority at the design stage. As a result, the Infiniti G37 Coupé has a full complement of six airbags, with dual-stage front airbags, seat belt sensors and passenger seat occupancy sensor. The front seats incorporate hip and thorax bags, while there are front-to-rear curtain airbags for protection in a side impact.
The standard is a pop-up bonnet, designed to offer greater crash protection for pedestrians. In the event of a collision, a small pyrotechnic charge raises the trailing edge of the bonnet close the lower edge of the windscreen. This creates a larger buffer between the bonnet and the top of the engine, providing a more yielding surface which in turn helps to reduce potential injuries.
The Quality Infiniti is synonymous with vehicle quality, and that's something that doesn't happen by accident. On the Tochigi production line in Japan every vehicle - not just every tenth - is laser scanned to ensure that panel gaps are within prescribed limits.
The super sports car boasts a purist design, the systematic incorporation of lightweight engineering and superior handling dynamics. At the same time, the SLS delivers the everyday utility and exemplary safety that typifies Mercedes, making the new Gullwing model the ideal synthesis of the strengths of Mercedes-Benz and AMG.
The new super sports car from Mercedes-Benz and AMG dazzles with its unparalleled technology package: an aluminum space-frame bodyshell with gullwing doors; an AMG 6.3-liter, front-mid V8 engine with a top power of 563 hp, 479 lb-ft of torque, and dry sump lubrication; seven-speed dual-clutch in a transaxle configuration; a sports chassis with aluminum double-wishbone suspension; and a DIN curb weight of 3,573 pounds. It's a combination that guarantees supreme handling dynamics. The car's ideal weight distribution between the front and rear axles (47 to 53 percent respectively) and its low center of gravity emphasize the outstanding sports car concept. The Gullwing model accelerates from 0 to 60 mph in 3.8 seconds and has a top speed of 196 mph (electronically limited).
Design: The distinctive design of the new Mercedes-Benz SLS AMG dazzles with its passionate sportiness and reinterprets the breathtaking design of the Mercedes-Benz 300 SL, one of the brightest design icons of the Mercedes-Benz brand. With its pure design, the new SLS AMG reflects the teachings of modern sports car design: The nearly 6-foot-long hood, the low greenhouse positioned far back, and the short rear with the extendable rear spoiler symbolize dynamism, as do the long wheelbase, the wide track, and the large wheels. The proportions are determined by the short overhangs and the design of the super sports car, with a low-slung, front-mid engine mounted well back and a dual-clutch transmission in a transaxle configuration. The stylistic highlight is without a doubt the gullwing doors, which impart the SLS AMG with incomparable charisma and make a unique statement in this vehicle segment.
It is not just the gullwing doors that awaken reminiscences of the Mercedes-Benz 300 SL. The characteristic wide radiator grille with the large Mercedes star and the wing-like fin are also reminiscent of the face of the legendary sports car. The three-dimensional, sculptured front with the low, v-shaped front skirt with lateral indentations gives the Gullwing model a powerful stance on the road. The car's dominance is underscored by six large air intakes and the wide-set, vertical headlamps with intriguing components: The central bixenon low-beam headlamps with metallic wing element are framed by two LED blinkers above and two LED daytime running lights below.
Influences from aircraft construction... Echoes of aircraft construction are stirred by the exposed Mercedes star, whose cone in profile resembles the air intake of a jet engine, and the long hood. The farther the viewer's eye wanders to the front, the greater the curvature of the hood. The same visual effect is produced by the design of the four "Silver Shadow" fins gracing the two air vent grilles on the end of the hood. These lines, which are typical for aircraft, also optically accelerate the air flowing past, giving the Mercedes-Benz SLS AMG an extremely dynamic appearance even when standing still.
Interior with aircraft design elements and racing functionality... Drivers who raise the gullwing doors of the Mercedes-Benz SLS AMG and sit down in the sports seats will experience a very special interior. In its conception, the Mercedes-Benz designers took their cue from aircraft construction to create an ambience that immediately evokes associations with plane cockpits. The defining stylistic element is the dashboard, whose powerfully extended wing-like profile creates the impression of great width. The dashboard incorporates "silver shadow" electroplated air vents with an adjustable set of nozzles, whose shape vividly calls to mind jet engines. The instrument cluster with its shift-up LED display and two white illuminated circular instruments also appears very sporty in the metallic silver shadow look. The silver dials have red pointers and a 225 mph scale. The main feature between the dashboard's two center air vents is the COMAND multi-media system with its 7-inch screen.
The elongated center console made of real matte metal also plays upon the plane cockpit theme. Among other things, the center console incorporates the AMG DRIVE UNIT, which is aligned towards the driver's seat and enables SLS owners to customize their vehicle set-up. The AMG SPEEDSHIFT DCT 7-speed sports transmission is operated by means of the E-SELECT lever, which is styled like a jet's thrust regulator. All of the control elements are constructed of real metal, boasting a shiny silver shadow surface.
The cockpit impression is rounded off by the concave interior trim of the gullwing doors, the high waistline clearance and the muscular side skirts, all of which also convey the feeling of sports car ergonomics. The high craftsmanship of the SLS interior is demonstrated by the use of refined materials such as nappa leather, real metal, and, as an option, real carbon appliqués. All of these features also express a great attention to detail. To help customize the interior, the leather is available in five designo colors: black, classic red, sand, porcelain and light brown.
Wide-opening gullwing doors for easy entry
Despite the low seating position typical of sports cars, which means the seats are located only 14.5-inches above the road surface, the wide opening gullwing doors ensure easy entry and exit. The designers made sure that the doors had as large an opening angle as possible, which is why they swing up by 70 degrees. Another consideration that is just as important is that the distance between the opened doors and the road surface is an ample 5 feet, while the size of the passage between the opened doors and the upper edge of the side skirts is a generous 42 inches. By contrast, the entry height (the distance between the road surface and the upper edge of the side skirts) is a low 17.7 inches. Another important criterion for ensuring an elegant entry and exit is that the opening and closing of the doors requires little effort even when it's very cold, because of two gas-dampers next to the door hinges.
The gullwing doors require less room to open than do conventional coupe doors and can be completely opened in standard-sized garages. The gullwing doors can be opened from the interior by means of a silver shadow opening handle. Thanks to the linkage system in the door's armrest, the door is easy to handle when closing. The buttons for the power windows, the central locking system and the exterior mirror adjustment are also easily accessible in the interior trim. The interior has a spacious feeling, due primarily to the large shoulder room of 58.4 inches and the wide elbow width of 63.2 inches. In conjunction with the generous headroom of 38.9 inches and the driver's effective legroom of 41.6 inches, the deep seating position is also relaxing. The passengers benefit from a relatively steep windscreen that provides a good view.
The button for unlocking the rear hatch can be found underneath the light switch. In addition, the hatch can also be opened by using the car keys. The luggage compartment has a volume of 6.2 cu. ft.
The aluminum space frame for light weight and highest strength
The vehicle's all-new body consists of an aluminum space frame, which combines intelligent, lightweight design with the highest strength and thus further boosts the SLS' excellent handling properties. Light aluminum profiles combine the force nodes to create a stable structure. The large, low-lying cross-sections of these aluminum profiles exhibit high resistance torques, thereby ensuring the desired direct transfer of drive, braking and chassis forces. Undesired flexibility is reduced by the structure; the vehicle responds rigidly, directly and as if it was almost free of torsion.
The intelligent aluminum space frame, which has been optimized in terms of weight, is 45 percent aluminum profiles, 31 percent aluminum paneling, 20 percent cast aluminum and four percent steel. Ultra high-tensile, hot-rolled steel is used in the A-pillars to further improve occupant protection. The bodyshell weight is 531 pounds — and given that the maximum power is 563 hp, represents a top value in the super sports car segment.
The Advanced AMG 6.3-liter V8 engine with an output of 563 hp
The heart of the new SLS is a high-powered eight-cylinder engine manufactured by Mercedes-AMG. The advanced 6.3-liter V-8 engine, which has an output of 563 hp at 6,800 rpm, makes the Gullwing vehicle one of the most powerful sports cars in its segment. In conjunction with the low vehicle weight, this results in a weight-power ratio of 6.3 lb/hp. The naturally aspirated engine provides its maximum torque of 479 lb-ft at 4,750 rpm. The Gullwing vehicle accelerates from 0 to 60 mph in 3.8 seconds and has an electronically limited top speed of 196 mph (all figures are preliminary). The high-torque V8 engine, which is called the M159 within the company, has a displacement of 6,208 cm³. It has been completely restructured compared to the basic M156 engine, and it displays the typical characteristics of high-performance racing engines.
The perfect synthesis of lightweight construction and stability
The use of high-strength components compensates for the increased burden on the engine resulting from its higher output. Forged pistons, a strengthened crankshaft mounting, an optimized crankcase structure, and improved lubrication by means of a need-regulated high-powered oil pump ensure maximum stability. In spite of the increased demands placed on it, the engine weight of the M159 has been further reduced. The forged pistons, as oscillating masses, make a particularly valuable contribution to this reduction. This results in a dry weight of 452 pounds, and thus a weight-power ratio of 0.8 lbs/hp — a value that is unmatched by any competitors. Sophisticated catalytic converter technology makes it possible to comply with current and future emissions limits such as EU5, LEV2 and ULEV.
Dual-clutch transmission in the transaxle configuration with the Torque Tube
The AMG 6.3-liter V-8 engine transmits its tremendous power to the rear axle via an especially lightweight drive shaft made of carbon — similar to the DTM C-Class touring car. The dual-clutch transmission is located on the rear axle (in line with the transaxle principle) and is tightly connected with the engine housing by means of a Torque Tube. In the Torque Tube, a carbon camshaft rotates with the same speed as the engine. The advantages of this sophisticated solution include the rigid connection between the engine and the transmission, which results in an optimal response to forces and torques.
The new AMG SPEEDSHIFT DCT seven-speed sports transmission is responsible for the power transmission. This dual-clutch transmission is characterized by quick shifting without any interruption of traction — minimum speeds of 100 milliseconds are possible. The driver has a choice of four different driving programs: C (Controlled Efficiency), S (Sport), S+ (Sport plus) and M (Manual), as well as a RACE START function. During the Sport, Sport plus and Manual driving programs, the automatic rev-matching function is active; all of these modes can be comfortably managed via the torque regulator in the AMG DRIVE UNIT. Optimal traction is guaranteed by the mechanical differential lock, which is integrated into the compact transmission housing.
Direct steering, differential lock and three-stage ESP
With a constant mechanical gear ratio of 13.6 : 1, the rack-and-pinion steering gear delivers a consistently direct steering feel, thereby meeting drivers' high expectations of a super sports car. The parameter power steering works with speed-dependent support and improves feedback for the driver as driving speed increases, a crucial factor when driving straight ahead at high speed. The mounting of the steering gear in front of the engine, on the frametype integral support, allows a particularly low engine position. The Gullwing car features a 3-stage ESP, giving the driver a choice of the three modes "ESP ON", "ESP SPORT" and "ESP OFF" at the push of a button. Even in "ESP OFF" mode, simply applying the brake pedal makes all ESP functions accessible again.
The traction logic of the acceleration skid control ASR is active in all three ESP modes. If a drive wheel begins to lose traction, a targeted activation of the brakes supplies a considerable improvement in traction — especially in combination with the mechanical multiple-disc limited-sl ip differential lock, which is standard equipment. During particularly dynamic driving, this allows more effective transfer of the engine output to the road.
AMG high-performance, ceramic-composite brakes, new "flow forming" wheels
The AMG high-performance compound brakes on the front axle ensure the vehicle quickly comes to a stop even under an enormous load. Even better braking performance is provided by the newly developed, optional ceramic-composite brake system with larger brake discs. Thanks to their increased hardness, the ceramic brake discs offer greater safety at high temperatures and are also impressive by virtue of their weight, which has been reduced by about 40 percent. Through the reduction of the unsprung masses, they further optimize the Gullwing model's handling — which becomes especially apparent during motorway driving around bends at high speed.
