Pontiac Solstice Coupe, 2009

Drawing inspiration from classic sports cars, the 2009 Pontiac Solstice coupe was created for drivers who appreciate both dramatic styling and balanced performance. Unveiled at the New York Auto Show as a GXP model, the Solstice coupe builds on the success of the convertible model while offering a greater range of all-season driving opportunities.

For drivers still wanting an open-air experience, the coupe also features a removable roof panel, fully opening the cockpit to all of the sensations of the road.

The new model has broader appeal . The coupe has all the design cues and pleasing performance of the original roadster, and is an all-season alternative for people who enjoy open-air driving.

The making of a coupe
It is a modern sports car with classic lines. The roofline has a "fastback" shape with stylized "rails" that run from the front of the roof to the rear, culminating in a stylish and functional ducktail-style rear spoiler.
The coupe's roof is fixed aft of the B-pillars, with side windows and a rear liftglass for access to the cargo area. The roof panel is easily removed from the passenger compartment, and an optional soft roof cover stores in the cargo area. A home storage case for the roof panel will be offered through GM Accessories.

Engineering the design
Despite its dramatic new look, engineers made only minor structural changes to create the Pontiac Solstice coupe. The rear fenders and rear fascia are the same as those on the convertible. New taillight assemblies flow more smoothly into the tapered roofline.
The sleek lines of the new roof give the car a fresh appearance, only minimal changes were made to the body structure - it's a great example of building on an already solid foundation.

Lightweight structure
The roof's structure was strengthened with additional support elements, including an aluminum roof bow attached with aluminum brackets. The bow and brackets are stiff, low in mass, a design feature that pervades the coupe's overall construction. The roof includes a lightweight sheet molding compound cover affixed to a rigid aluminum frame for additional lightweight support. A lightweight magnesium roof panel frame weighs just 31 pounds (14.2 kg) and can be removed by one person. The cover is also made of sheet molding compound.

Powertrain and suspension
Because the change to a coupe body style resulted in only a slight increase in curb weight, no drivetrain or suspension changes were necessary to shift from the convertible body structure. Initial tests have shown that the Solstice coupe will deliver ride and handling, acceleration, braking and fuel economy comparable to the convertible model.
The coupe is powered by a standard 2.4L Ecotec four-cylinder engine that generates 173 horsepower (129 kW), while the GXP version is equipped with a 2.0L turbocharged Ecotec engine with 260 horsepower (194 kW).

Interior additions
Much of the coupe's interior remains the same as that of the convertible. However, the area behind the seats was redesigned for easy access to the cargo area, and a storage tray was mounted directly behind the headrests.

Removing the folding-top mechanism made way for a new, flat cargo floor and several storage compartments. The cargo area's covered bins provide secure storage for smaller items. Cargo tie-down hooks help secure irregularly shaped items.

Venturi Astrolab, 2007

Astrolab (latin astro = star, labe = to take) Takes energy from the sun, in order to move...

ELECTRO-SOLAR HYBRID

With 3.6 sqm of photovoltaic cells giving an exceptional yield of 21%, and covered by a film composed of nano-prisms enabling denser concentration of solar energy, Venturi Astrolab is the first high-performance solar vehicle to be commercialized in the world.

Capable of working with very little energy (16 kWc engine) and of recharging even when in motion, this vehicle of another era does not need to be permanently exposed to the sun in order to move. Its last-generation NiMH Venturi NIV-7 batteries - liquid cooled - in fact enable it to restitute stored energy, whether solar or from the electricity supply, making it the first electro-solar hybrid vehicle.

With a top speed of 120 kmhr and autonomy of 110 km, Venturi Astrolab is a real Solar Commuter making extensive trips on a daily basis.
Made by order, Venturi Astrolab is a vehicle with a considerable technological head-start on all other productions worldwide. It meets the needs of people's inter-urban travel, at the forefront of the best that is being achieved in terms of technology.

CONSUMPTION = 0, EMISSIONS = 0
This is very first vehicle that consumes no fossile resources in order to work the emissions of CO2 required for its construction will even be compensated for by evironmental actions.

A parallel can be drawn between Venturi Astrolab and a sailboat both advance silently while making best use of the elements provided by Nature. And the piloting of both makes for sensations unlike any other.

To attain this level of performance while using very little energy, Venturi Astrolab has been designed like a Formula 1 its carbon monocoque chassis is ultra-light and serves as an oversized protection cell ensuring the safety of its occupants in the event of a collision. Its profile recalls the aqua-dynamic design of great racing yachts.

A NEW ERA IN TERMS OF DESIGN
Venturi Astrolab also opens up a new era as regards automobile architecture light and highprofiled, it offers the rays of the sun 3.6 sqm of today's most sophisticated photovoltaic cells (for an overall vehicle length under 4 m).

Its designer Sacha Lakic describes Venturi Astrolab as a flying wing set on four wheels.

Optimised to incoporate its solar cells, the Venturi Astrolab's design takes into account the effect of passengers' weight on the vehicle's dynamic behaviour. Very light when empty, the tandem architecture makes for perfect balance, whether the vehicle is occupied by one person or two.
With Astrolab, Venturi has given priority to the solar solution as its energy conversion technology all of its developments allow us to hope for even higher yields in the years to come. Within a 30-year perspective, Venturi is the only automobile manufacturer capable of presenting such a solution while ensuring new driving sensations and an essential aspect of automobiles the dream.
