Rinspeed iChange Concept, 2009

The Swiss auto powerhouse Rinspeed presents the Rinspeed iChange Concept, the world's first car whose body adapts to the number of passengers on board. For Rinspeed boss Rinderknecht the vehicle is more than just a clever concept car. "The Rinspeed iChange Concept is a symbol for the fundamental changes the auto industry undergoes worldwide. And it is clear that only those companies will survive that have innovative answers for the demands of a new automotive era." The visionary Rinderknecht is convinced that the days of gas-guzzling behemoths are coming to an end: "The Rinspeed iChange Concept is a signal for the coming global changes to individual mobility. We need to be ready to meet these challenges with new ideas."

In seconds a streamlined one-seater sports car transforms into a comfortable car with ample room for three. The trick: At the push of a button the rear end of the teardrop-shaped car magically pops up. "We have designed and built an extremely flexible vehicle. In it we have brought the themes of versatility and continually changing energy demands to their logical conclusions." The result is a streamlined, lightweight zero-emission car with dramatically reduced energy consumption.

The basic idea behind the 'Rinspeed iChange Concept: The energy demand of a vehicle depends mostly on its weight, the type of engine it uses, and its aerodynamic properties. The engineering-services company Esoro that traditionally builds Rinspeed concept cars has built an extremely lightweight car weighing in at only 1050 kilograms. To power the car, the Swiss specialists chose an electric motor. The idea of the pop-up rear end was conceived to account for the sizeable effect aerodynamics play in fuel consumption.

While other cars always have to ferry around their puffed-up exteriors that can accommodate up to seven passengers even if they're just transporting a single soul, the Rinspeed iChange Concept features an adaptive body. The sole driver is conveyed in a teardrop-shaped car that offers optimal aerodynamic properties and thus minimized energy consumption. If more than one person need to be transported the expanding rear provides room for two passengers. As a result of the increased weight and no longer optimal aerodynamics the energy consumption increases - but only for the time passengers are actually on board.

The energy for the electric motor comes from lithium-ion batteries that are available in two different stack configurations for short- and long-distance driving. The electric motor of the Rinspeed iChange Concept produces 150kW, capable of propelling the car to a top speed of 220 km/h. The sprint from rest to 100 km/h takes just slightly over four seconds. This impressive performance is made possible with the help of a six-speed pre-selector gearbox from the Subaru WRX car. The central research department of Siemens AG (Corporate Technology, CT) supplied the integration technology for engine/generator, electronics and battery connection interface. Siemens has long been one of the world leaders for energy systems and eco technology with pioneering concepts for electric drive systems. Its products cover the entire electric value-added chain from generation to distribution to consumption. The gearbox and drivetrain are lubricated with eco-friendly lubricants from Motorex. Custom-made lightweight 17" and 18" forged wheels with aerodynamic shrouds are supplied by light-alloy wheel specialists AEZ. Pirelli P Zero tires in size 215/40-17 in front and size 245/40-18 in back provide optimal grip.

An initial walk-around reveals that the concept car has no doors. The entire electrically powered roof section of the car measuring just 1.03 meters in height tilts forward to allow passengers to board. Also gone are such mundane things as a key. Its role is filled by an Apple iPhone, which also controls the most important vehicle functions. The Rinspeed iChange Concept is drastically different than ordinary cars in every detail: At the heart of the concept car lies the groundbreaking next-generation Harman/Kardon infotainment system. The system uses an innovative Intel processor technology that guarantees minimized power consumption. The same is true for the Harman/Kardon high-efficiency audio system. This revolutionary technology meets highest demands on sound quality, weighs much less than ordinary systems and at the same time uses only a fraction of energy. This opens the door to a new dimension of energy efficiency. The route guidance of the navigation system is also especially eco-friendly: The system calculates the most energy-saving route and displays the directions in realistic 3D view. Eberspächer Group from Esslingen, Germany is one of the world leaders in car heaters. Specifically for the „iChange" project Eberspächer developed custom-tailored electric and fuel-burning heating systems. Both systems are geared toward the specific requirements and conditions of electric vehicles.

The pure wool used in the interior was further refined into high-tech wool by Schoeller using state-of-the-art processes. The wool is spun and died in accordance with the highest eco standards. It provides an extremely extravagant ambiance in the Rinspeed iChange Concept, looks stunning and is delicate to the touch. The competence partner Strähle + Hess transformed this natural product into a striking interior. Its surface character and materiality combine to create a symbiosis of shell, firmness and frothy air. Unconventional techniques create unusual surfaces. The seams of the seats are reversed and the removable seats cushions are adorned with the prototype's name. Xmobil provided further customization services. While textiles can be found in the Rinspeed iChange Concept in their original form in other areas, they are newly interpreted on seats and cargo floor using various refinement techniques such as braiding and gathering and a combination of both. Leather strips alternate with technical textiles. The seat cushions are interchangeable, braided felt alternates with technical textiles formed into three-dimensional shapes. This transfers the adaptive concept of the Rinspeed iChange Concept to the interior as well. The diamond-coated anti-slip floor is supplied by abrasives specialist KGS.

The Swiss Federal Ministry for Energy (Bundesamt für Energie) supports the „iChange" project as a groundbreaking research and development project. Solar panels on the top and sides of the roof provide electricity to the fan to keep temperatures in the Rinspeed iChange Concept comfortably low on hot summer days. The large Sharp solar panels also provide additional eco-friendly charging of the batteries.

With the Rinspeed iChange Concept Rinderknecht, a passionate C. F. Bucherer watch wearer, and his partners once more want to provide food for thought for the automotive industry. The Swiss car visionary: "If we want to maintain our individual mobility in the future we have to rethink the car in its entirety, without taboos. Most of all, we have to take its ecological aspects into consideration." And in the end everyone has to personally answer the same question: Am I ready and willing to change myself, do and can 'I change'?

Volvo S60 Concept, 2009

Scandinavian inspiration

The front of the Volvo S60 Concept sports the enlarged iron mark in the trapezoidal grille. The two lamps that flank the grill emphasise the vertical stance of the front and highlight the bonnet's V-shape. The angled headlamps flow up into the strongly sculptured bonnet and combined with the lower air intake's reverse trapezoidal shape, this gives the concept car a very expressive "face".

Viewed from the side, the concept car's slim coupe roofline and window graphics are accompanied by an entirely new shoulder line, forming a gentle double wave, stretching from the headlamps all the way to the rear. Both the seven-spoke 20-inch wheels and the tread of the low-profile tyres have been specially designed, while the bronze-painted brake callipers match the "Warm Liquid Copper" livery.

The unique rear parallelogram doors offer a spectacular show when they are opened and closed. Door opening is initiated by pressing a button and the movement starts off in the traditional way. In the next phase, the forward section swings out away from the car's body and the door glides parallel with the side of the car until it reaches its end position by the rear wheel. Since the car does not have a B-pillar between the front and rear seats, this door configuration offers exceptionally generous entry and exit access.

The transparent attachment of the door mirrors illuminates and becomes part of the indicator function. The panorama roof is another ingredient that contributes to the concept car's airy Scandinavian aura.

Viking longboats in the headlamps
In each of the headlamps, the lights create a silhouette of two miniature Viking longboats sailing side by side, one for main beam and one for dipped beam. When driving in the dark, the light is reflected from the concealed, upward-facing High Performance LED bulbs, projected ahead by the ships' filled sails.
A closer look reveals more detail. The compact cooling system for the LED bulbs has protruding cooling blocks made out of aluminum, semi-visible under the ships' hulls. This design creates the illusion of shimmering glass panels that float above a dark and mysterious Scandinavian sea.

Inspiration from the racing track
The tail lamps, which follow the curve of the rear shoulders, are as advanced as the headlamps. When switched off, the lamp panels show no trace of the traditional red or yellow. But when activated, the position marker lights, brake lights and turn indicators come on in their correct colours with the help of LED bulbs. The solid glass panel is sectioned into horizontal "slices" that create the visual impression of a three-dimensional architect drawing when the lights come on.
At the rear there is also a retractable diffuser that adjusts with vehicle speed to give better aerodynamic properties.

New technology detects pedestrians in the danger zone
The Volvo S60 Concept also presents a safety innovation that can detect a pedestrian who steps out into the path of the car and the car's full braking power is automatically activated if the driver does not respond to the danger. The technology, Collision Warning with Full Auto Brake and pedestrian detection, will be introduced in the all-new Volvo S60.

Elevates the brand's image
The Volvo S60 Concept was created to pave the way for Volvo Cars in one of the automotive world's most focused segments, characterised by razor-sharp competition.
