2008 HSV W427

Holden Special Vehicles (HSV) unveiled its 7-liter Supercar W427 at the 2008 Melbourne Motor Show in conjunction with the company’s 20th anniversary celebrations. The final paint scheme, Panorama Silver, is the same as the original Group A SS VL Commodore that was released exactly 20 years ago at the 1988 Melbourne Motor Show.

According to HSV Managing Director, Scott Grant, the W427 could quite possibly the fastest road registrable Supercar ever produced in Australia and among the quickest anywhere around the world and also will be one of the safest cars HSV has ever put on the road. The power output is yet to be known but it was reported to deliver 370 kW of power and 640 Nm of torque.

The HSV W427 features a new 6 piston front braking system, a revised ESP calibration, 6 air bags, improved handling, new Magnetic Ride Control settings and a bimodal active exhaust system.

Other features include an all new front fascia, a 3 piece carbon fiber rear spoiler, 20 inch machined faced alloy wheel, unique exhaust tips and red leather interior.

The HSV W427 will only be produced in limited numbers and will be available for sale in dealerships in the third quarter of 2008.
