Hsv Unveil New 7.0l Engine W427

[Bliksem]

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.

Just heard about this on the news.

[Flynnn]

Let's hear the price tag again...

$125,000.00

[sh@un]

Not bad

I'm sure it'll be number 1 with a bullet on a Bankstown rebirthers hit list when it comes out

[Bliksem]

If nothin else I like that they're using a dry sump setup

[Yo-Yo]

Whoa, talk about "compensating"

shame the car still looks like arse, but each to their own i guess

EDIT: Just saw the coupe holden in the other thread, MUCH nicer... but still a holden

[Nick033]

7.0ltrs cocks must be small

doesnt look like a supercar

wheels look like shit

[black_gtst]

give it a couple of months and a new GTR will be the same price as this slug. engines just keep gettin bigger and bigger cause they gettin fatter and fatter

[bigcarl]

it just amazes me that in this day and age with climate change and carbon trading schemes set to go ahead with companies being able to ff-set there carbon foot prints e.t.c. here is another prime example of a car company that is not only ignoring all this with production of this car but instead of trying to make a more efficient performance car they bring out a 7litre v8! every couple of years . first a 5.7litre then a 6litre now lets just add even more weight to it and chuck in an even bigger donk. and for all the fuel economy whinges out there we will chuck in a six speed over drive , drive it at 80km/h around lang lang sitting on 1200rpm so that we can claim fuel efficiency figures that you and i in the real world will never achieve! i mean how many v8 owners dont hammer the crap out of there cars from stand still at ever set of lights ! specially when they see a 2litre import in the lane next to them. lol.my 2 cents.

[Duncan]

wow. everyone wants to look like an r35 these days. lancers. commodores. yawn.

still, its great to see the motor here, it is a good race motor so this might make the bits easier to get.

[Argh-Ess]

$120k is serious money for a HSV. Looks pretty much like a senator anyway.

[typevu]

Holden's attempt to compete on the same level as the R35 GTR.... definitely doesnt look like a"super car", interior looks cheap - something about the red... the engines nice should be in the coupe 60 body i reckon.

[tridentt150v]

Where's the 4wd Holden have been threatening the world with............and I'm not talking Rodeo!!!

GTR looks much better value IMO.

[Bumblebee]

its a fast family car hahahaha thats all it will ever be... EVER

This is exactly what I was thinking...This is 2008, price of crude oil just hit $102 a barrel...unleaded for $2 a litre is not as far away as we may think....With all the problems with the environment and as we are supposed to be trying to cut greenhouse emmisions along comes this great gas guzzler...WTF are they thinking ? Hey why not go the whole hog and fit a 10 litre V10...that will show em !!...When is Holden going to realise that you do not need to have a big capacity engine to make horsepower.? BMW make this power out of a 5 litre V10...Why cant Holden ditch the pushrod and 2 valve engine and go Hitech ..... ?

[RyanVLSL]

Um it's not Holden who build these engines, it's GM in the states. The biggest engine Holden has ever made, was the 5L 304. (Though a 5.7 stroker was available for the VS GTS-R)

Edited February 29, 2008 by RyanVLSL

[Bumblebee]

yes your right.. holden didnt make this engine but who said they cant make theyre own???

They can and have before.. they just think its more economical for them to purchase engines from the states as oppose to R & D they're own new engine.

7lts to make 370kw.. what a waste of space...

ummm champ you did notice I did say Fit this engine - Not build ?...Thanks but I have worked on a few Holden V8s , I am well aware of what they built and didnt....At least with the Yanks there fuel is a lot cheaper than here...More GM usa being an Ass than holden for building such a large engine....Not necessary...
