Hennessey Performance Engineering today announced that it is introducing the company's first concept car - The Venom GT.

Penned by British auto designer, Steve Everitt, the Venom GT would incorporate Hennessey's potent Venom 1000 Twin Turbo Viper V10 powerplant into a light weight mid-engine chassis weighing "under 2,700 lbs". Power would be run through a 6-speed transmission or optional sequential gearbox.

With a power to weight ratio of just 2.7 lbs per bhp Hennessey estimates that the Venom GT could attain 0 to 100 km/h times in less than 2.5 sec. and a 0-300 km/h time of around 14 seconds. Company founder, John Hennessey, is careful to point out that the Venom GT is not being built as a "Veyron Slayer". out, "The Veyron is an ultra fast and ultra luxurious grand touring car which also happens to be quicker and faster than any other road car, except for our Venom 1000 Twin Turbo SRT which beat the Veyron earlier this year from 0-200 mph. The Venom GT will be a much more engaging sports car to drive by challenging the driver with 1000+ HP in a chassis that is nearly 1500 lbs lighter than the Veyron."

Hennessey said, "The company already has existing Venom 1000 Twin Turbo clients interested in ordering the lighter, mid-engined Venom GT. "Right now are taking a serious look at building 2 concept cars that could be shown to the public sometime in 2009. If there is enough demand we may consider doing a very limited production run of the Venom GT."

If the Venom GT goes into production, it would be built at the company's facility at Lonestar Motorsports Park which is located just west of Houston, Texas.

Following repeated requests by motor racing enthusiasts among the SLR. CLUB members, the British motor racing specialists RML Group (Ray Mallock Ltd) have developed the new SLR 722 GT. This puristic super-sportscar is designed exclusively for the racetrack, has no approval for on-road use and will take part in the SLR. CLUB Trophy, a competition series forming part of the SLR. CLUB racetrack programme in Europe.

Compared to the series-production version, the SLR 722 GT has been uniquely and comprehensively re-engineered by RML, especially with respect to the suspension, braking system, aerodynamics, interior and exhaust system. More than 400 components were redesigned. The key data of this edition limited to 21 two-seaters kerb weight 1390 kilograms, maximum output 500 kW/680 ps at 1.75 bar boost, and maximum torque of 830 Newton metres to guarantee maximum racetrack performance.

The SLR 722 GT already makes a powerful impression at standstill: new body components such as the front apron with front splitter, wide wings, prominent side skirts, the large rear diffuser and the fixed rear spoiler are obvious indicators of outstanding racetrack performance and extensive aerodynamic development work.

The likewise redesigned bonnet conceals a supercharged AMG 5.5-litre V8-engine uprated by RML to develop a peak output of 500 kW/680 ps and a maximum torque of 830 Newton metres. A racing air filter and a new exhaust system ensure outstanding responsiveness and an even more striking engine sound. Dispensing with numerous comfort features means that the SLR 722 GT tips the scales at a kerb weight of just 1390 kilograms. The result is a favourable power-to-weight ratio of 2.0 kg/ps and an acceleration time of 3.3 seconds from standstill to 100 km/h. The maximum speed is 315 km/h.

Modified suspension with central wheel locks

Fast lap times are guaranteed by the newly developed suspension: a new wheel location system at both front and rear provides improved kinematics and lateral dynamics. A modified stabiliser at the front axle reduces roll when cornering, while an adjustable wheel camber combined with shock absorbers with variable compression and rebound characteristics allow the suspension to be set up for different racetracks. 18-inch light- alloy wheels with central locks allow fast tyre-changes during a race which is also assisted by the pneumatic jacking system.

Power is transferred by a five-speed automatic transmission with steering wheel shift paddles, which has been adapted to racing conditions. A mechanical locking differential with a locking effect of 70 percent under acceleration and 80 percent on the overrun ensures traction without loss of power. Highly efficient, fade- resistant braking is provided by the new racing brakes complying with FIA GT regulations, which feature a modified cooling airflow and adjustable balance. The interior of the SLR 722 GT is characterised by the functional atmosphere of a thoroughbred racing car. Eye-catching details include a rollover cage, a redesigned instrument panel with a racing display, a racing steering wheel and bucket seats with six-point seat belts.

Developed by motor racing specialists

Development, production and sales of the SLR 722 GT are in the hands of the renowned British motorsport and automotive specialists RML Group. A maximum of 21 vehicles will be produced. Servicing and participation in racing events is also under the aegis of RML in collaboration with the SLR.SAFETY & SPEED ACADEMY.

The owners of cars already ordered are all members of the SLR. CLUB a highly exclusive community which organises events relating to the SLR and is chaired by Dr. Dieter Zetsche, Chairman of Daimler AG and CEO of Mercedes-Benz Cars. The SLR.SAFETY & SPEED ACADEMY forming part of the SLR. CLUB offers special driver training courses, and enables customers to acquire a national Category A racing licence.

Prominent, highly-skilled instructors for the SLR. CLUB include David Coulthard, Klaus Ludwig, Jochen Mass, Chris Goodwin and Christina Surer. The central focus of SLR. CLUB events is on automotive passion, professionalism and perfection.

DETROIT — General Motors plans a new family of rear-wheel-drive vehicles for Pontiac. The G8 line will include a sedan followed by a wagon and sport truck.

All will be modeled after products sold by GM's Australian subsidiary, Holden, according to three sources familiar with the project. The vehicles will be assembled in Australia.

The G8 sedan goes on sale early next year. It replaces the Grand Prix and will be Pontiac's flagship sedan with a starting price around $25,000.
