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."

Not digging the red leather. But that should be a beast to drive.

 

Wow thats sexy

 

Fugging Aussies!

 

That is sexy as hell

 

Nice!

 

That is damn sexy!!!! I wish I could get one.

 

Damn awesome.

 

I dig every square inch or it.

Nice! I'll drive it

 

Thats like the ultimate daily driver, enough room for a nice long trip. And the power to just own almost anything that pulls up next to you.

Very very nice. It would be nice to see that here in the states.

 

Agree, we get screwed over here.

 

how do we get GM to put those kind of seats in vette and future camaros!!!!!

fk are we going to have sedans with real seats and not the zo6!

 

Not bad at all........

 

Damn nice car.

 

If only America got badass cars like the Aussies. No, we get the Toyota Prius. Sick car, I'd love to daily drive that. The body lines look similar to the G8/Aussie version...

 

Now that i look closely at the seats, they seem pretty similar to those we will be seeing in the 2009 Cadillac CTS-V.

If you go down the page a bit, you will see a picture of one of the seats in the V. It looks like a pretty similar design, but more than likely made with different materials.

Yeah, we get screwed over here... the Z06 will probably be cheaper, looks better and can outperform that thing, what a rip.

 

We aren't basing the getting "screwed" quote just off this car alone. Look at all the new cars that Holden and Ford just showed off to be produced for the Aussies, and they look awesome. The Z06 is a fantastic car, and the ZR1 is going to be the car that sets the benchmark for what real performance is. But consider if we weren't going through all the bullsh*t of high gas prices and people crying over the enviroment, this W427 could have been the Pontiac G8 GXP. And i think that would have been awesome, but we do usually get the short end of the stick. Example the 2006 Pontiac GTO, what it should have been, 2006 Vauxhall Monaro VXR 500.
