Holden Special Vehicles unveil seven litre Supercar the W427
Holden Special Vehicles today unveiled a seven litre program at the 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, Scott
Grant said.
The W427 will be quite possibly the fastest road registrable Supercar ever
produced in Australia and among the quickest anywhere around the world, he said.
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, Scott Grant said.
A new six piston front braking system will provide a 50% increase in pad area, while
the W427 also receives a revised ESP calibration, six air bags, improved handling
and new Magnetic Ride Control settings.
The 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.
Scott Grant said HSV would be introducing a unique customer relations program to
accompany the launch of the new vehicle.
The W427 will only be produced in limited numbers and we want to reflect that
exclusivity in how we connect with our Supercar customers, Scott Grant said.
This program will see the LS7 engine being fitted at Clayton, along with the dry
sump system and a range of other engineering features. We are looking at
opportunities to allow owners to visit HSV and view the unique manufacturing
process that goes into building this car.
The 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.
Make no mistake, while the specifications of the car unveiled on the stand today at
the Motorshow may change slightly between now and when production begins, this
car is destined to make as big an impact as the original Walkinshaw twenty years
ago.

seven liters?

that is serious.

[clutch-monkey]

i dislike the nose. i prefer the CSV 427...or as a concept, the coupe 60.

Australians must be gods at making cars, they take press release pictures of them on the moon... how cool is that?

</idiotic comment>

I'd rock it.

nah, just used the same studio they faked the moon landings with.
...or, it's an analogy for rising fuel prices

[092326001]

specs sound mad but the nose is awful, and those exhaust look absolutely miniscule

[Ferrer]

It is like a 4-door Z06. And like the M3 Saloon it looks like it colud almost be a sensible family car. Almost.

[clutch-monkey]

the only thing stopping it from being sensible is the fuel economy it gets, imo... worth it to scare m5 drivers though?

[fpv_gtho]

30% stiffer springs over the already stiff GTS would make it impractible as well. For comparisons sake, between the Falcon XR8 and GT the front springs are about 5% stiffer whilst the rear springs are a similar number softer...

[TVR IS KING]

Americans and Australians like to think they build the same kind of cars. Powerful, tough V8s.
Only we do it well, learn from us.

I forgot that Australia was responsible for engineering and producing the LS7.

Zing.

Yeah, the Corvette for example, is a real piece of crap. It only has huge power, great design, an amazing engine, and is capable of thrashing 99% of cars on the road, including much more expensive cars.

American sportscars suck.

The vette is nice - it is a stand out among a herd of useless crap
