Holden Special Vehicles unveiled a seven litre program at the 2008 Melbourne Motor Show, the last instalment of the company s 20th anniversary celebrations.
The car to be known in its final development stages as the W427 is finished in the same Panorama Silver paint scheme as the original Group A SS VL Commodore, released at the Melbourne Motor Show of 1988, exactly 20 years ago.
HSV Managing Director, Scott Grant, said the W427 was a tribute to how far the company has come in just twenty years.
A new six piston front braking system will provide a 50% increase in pad area, while the Holden W427 also receives a revised ESP calibration, six air bags, improved handling and new Magnetic Ride Control settings.
The Holden W427 receives a bimodal active exhaust system to improve noise quality and back pressure management.
Styling and design highlights include an all new front fascia, a three piece carbon fibre rear spoiler, 20 inch machined faced alloy wheel, unique exhaust tips and red leather interior.
The Holden W427 will go into production in the middle of the year and will be available for sale in dealerships in the third quarter of 2008.
