HSV To Release a Limited-Edition Supercar

    0 Ratings
    MELBOURNE, Australia — Holden Special Vehicles, the performance arm of General Motors unit Holden, has thrown down the hot-sedan gauntlet with the announcement that it will build a new supercar based on the Holden Commodore and powered by the Corvette Z06 7.0-liter LS7 V8.

    The new car, to be produced in limited numbers as part of HSV's 20th-anniversary celebrations, is currently known only as the W427 concept. It is expected to hit showrooms in Australia in the third quarter of 2008.

    Few details have been released by HSV, but a company spokesman has revealed that the car is in the early stages of development and will feature a number of components developed from the company's V8 Supercar racing program.

    Expected to develop 496 horsepower at 6,500 rpm and 472 pound-feet of torque at 5,000 rpm, the new model should be able to sprint from zero to 60 mph in just 4.5 seconds and reach a top speed of 155 mph. That would likely make it the fastest road car ever produced in Australia and among the quickest in the world.

    According to reports, the production version of the W427 is also headed to the U.K., where it will be sold as a flagship version of Vauxhall's VXR8. There are no reports that the car will be available in left-hand-drive form for the U.S. market.

    Performance features of the concept include a carbon-fiber rear spoiler, six-piston brakes, 20-inch wheels, a custom induction system and an uprated limited-slip differential, clutch and Tremec TR6060 six-speed manual gearbox. The car also features Magnetic Ride Suspension.

    What this means to you: Here's a reason to look for news bulletins from Australia for the next few months. — Mike Jarvis, Correspondent
