HSV W427 Concept

HSV W427 Concept



HSV (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.

To be able to produce a vehicle of these proportions is truly remarkable.

The W427 will be quite possibly the fastest road registrable Supercar ever produced in Australia and among the quickest anywhere around the world.

While power output figures are still to be confirmed, the W427 is likely to produce in excess of 370kW of power and 640NM of torque.

It will also be one of the safest cars HSV has ever put on the road.
