VE Sporties To Kill HSV?

Holden’s sporting VEs will be Australia’s fastest ever production cars. So does that signal the end to HSV?

There is little doubt that the new VE Commodore will set new safety, performance and engineering benchmarks for a locally-produced full-sized passenger car. And the new sporty models Holden will debut this Sunday to anchor the range’s user-chooser sales will raise the performance bar even beyond current HSV models. So is this the end for the lion’s go-fast arm?

Upping the ante further presents a huge challenge for HSV. Delivering a new VE-based range that will command a premium over the factory VE models won’t be easy. But there's little question that HSV will play a large role is Holden's global plans for VE. And if you consider various developments and changes the Clayton (Vic) based organisation has made over the last 12 months, the path forward is clear.

TOP SHELF APPOINTMENTS

The recruitment of former Rolls-Royce engineering chief Phil Harding as HSV’s managing director provides an insight into the elite engineering and presentation levels now required to create some ‘air’ between HSV and comparable Holden models.

The loss of the Monaro body will force HSV to present its VE range as a worthy replacement and substitute for its Z-series GTO models at home and in certain export markets.

Without a stylish two-door body with which to distinguish a GTO replacement, the HSV range will be more often benchmarked against the current crop of premium performance sedans. These include the Chrysler 300C range and the premium Europeans which continue to gain ground in Australia. Expect the HSV range to highlight the rakish four-door coupe style of the VE body.

HSV has recently been criticized for over-production which resulted in its premium models discounted below the retail price of the Commodore SS at the start of 2006. To counter this, several superficial limited editions were rushed out in an attempt to individualise its Z-series mainstream production but the damage had been done.

With residual values critical to a HSV purchase, CarPoint believes that a cornerstone to HSV’s VE marketing will be to maintain exclusivity within the Australian market and generate extra volume through exports and additional models.

IN THE ENGINE ROOM

Holden traditionally introduces new engines one model series before an all-new model so that engineers don’t have to confront the major development issues together. HSV’s Z series introduced the new LS2 engine from the Corvette C6 but in a lower state of tune than the previous LS1 (after it was fitted with a more restrictive exhaust).

Previous Holden management made it clear that 300kW was the sensible limit for the VT-VZ platform hence LS2 power output was restricted to 297kW. That arbitary limit no longer applies.

To maintain current HSV performance levels with the VE’s expected extra 100kg, HSV must improve LS2 output without upping capacity (5967cc). However, fuel consumption is now kicking in as an issue even in performance circles.

CarPoint believes that HSV will use exhaust tweaks to boost power to 305-312kW and the current 530Nm torque figure will rise to around 542-550Nm. Further performance and economy gains will be generated by software and driveline improvements.

And as for a rival to FPV’s F6 in-line six cylinder turbo range? Off the agenda -- the all-aluminium LS2 engine does not suffer from the same weight and fuel economy issues as FPV’s Boss 290 and offers superior performance. A hot turbo version of Holden’s Alloytech V6 does not have the same potential to provide unique performance increments, economy or handling balance over an upgraded HSV LS2.

A NEW GTS

When the GTS was dropped with the Z series, then HSV marketing chief, Chris Payne made it clear that the model would not reappear until it could bring a substantial lift in performance, handling and braking over other models.

There continues to be persistent rumours that HSV has been working on a GTS powered by the 7-litre LS7 as introduced in the Corvette Z06 series. This monster 377kW/637Nm engine was never a possibility in the previous Z series, however, the advanced VE platform is another issue -- especially when it could share export showrooms wearing a Chevrolet badge as a premium four-door alternative to the donor Corvette.

This engine is not cheap and demands serious driveline upgrades. The potential for controversy over power figures would be offset by the added safety and weight of the new range and marketing the new VE GTS as a highly exclusive, limited edition $100,000 plus model.

It is believed that this is HSV’s first preference but there are interim capacities between six and seven litres if availability and pricing becomes a problem. Expect the hi-po GTS to be previewed at the 2007 Melbourne Motor Show and to be earmarked for certain European and Middle Eastern export markets.

GEARING UP

Until now, HSV has been forced to take a backseat in the area of independent transmission development.

No HSV auto model has yet been fitted with a sequential manual selection function when Tickford and FPV rivals have offered this feature since early AU days. GM’s crude four-speed auto has not done any favours to any HSV model and only approached acceptability when Pontiac GTO upgrades were applied to HSV’s Z-series.

The Tremec T56 six-speed manual was equally lack-lustre in most HSV models and again only reached acceptability with the M12 upgrade from the GTO in the Z-series.

The VE will mark an opportunity to further tailor the manual M12 or derivative to HSV’s application for further refinement. HSV is under some pressure to be the first to introduce a race-style sequential shift for the manual transmission. At best, this may be offered as a “sports shift” option or reserved for the GTS.

The auto, however, will be the latest GM six-speed and will feature some form of manual shift function for the first time. Expect HSV to present such a feature in line with its motorsport links.

MAGNETIC ATTRACTION

The VE also marks the end of the days when HSV could restrict suspension travel then firm up the bushes, springs and shockers to hide the geometry compromises in the factory Commodore.

Now that FPV suspension virtually matches the equivalent Ford XR spec, it shows what happens when the factory gets it right. HSV is not in a position to further tighten up VE suspension and lose refinement when the VE starting point (and benchmark opposition) will be so good.

HSV has been quite open about its aim to match the refinement of its best rivals while maintaining the benchmark track performance of its wild Dealer Team Spec (DTS) using the one suspension. There is only one way it can do this.

There have been persistent reports that local suppliers have been gearing up to build Delphi MagneRide technology into the top-spec VE damper units.

This technology uses a damper fluid filled with tiny ferrous particles that respond to different levels of an electro-magnetic field. Depending on how these particles are aligned by the magnetic force, they can change the viscosity of the fluid (and hence the damping characteristics) in an instant.

Unlike conventional adjustable dampers which rely on restricting fluid flow, this system reacts in an instant and doesn’t introduce harshness when damper valving remains as tuned for that suspension.

Whereas HSV’s rarefied and expensive Ohlins adjustable suspension made sense only to track-orientated owners, the Magneride system can make an instant and noticeable difference in all road conditions. It has a low current draw, fits in the same space as conventional dampers and requires only sensors and a control unit to operate.

HSV has the opportunity to be the first local to lift its range into rarefied Ferrari, Corvette and Audi TT territory with this technology. Expect it to be fitted from ClubSport R8 level but don’t be surprised if HSV uses it as a point of distinction in all models.

A NEW FACE

Remember when HSV said at the Coupe4 launch that it would rely increasingly on sheet metal changes to distinguish HSV models? VE is the first opportunity to do this and the success of the VZ Monaro bonnet vents and VZ SS side vents have prompted both Holden and HSV to go further down this track.

VE is also the first HSV model range to be prepared by HSV’s own local design studio when previously this vital work was sub-contracted with mixed results. Plastic add-ons now belong to another market niche and the new Walkinshaw Performance hot shop, a sister company to HSV, intends to be in the front seat with VE body add-ons.

This leaves HSV to find different ways of distinguishing the VE range. Already exposed are the major sheet metal tweaks in the front guards with the large Range Rover/Jaguar-style vertical gills. There is an opportunity to match these in the rear guards on upper levels.

Expect not only more aggressive detailing but look for more embedded changes that will be harder for backyarders to replicate. Different exhaust treatments with the VE’s fuel tank moved ahead of the rear axle will be exquisite.

Expectations inside the cabin have risen so strongly that HSV’s cheap looking add-ons and gauges will no longer be enough. Again, the changes will be more far-reaching and classier. There will still be an aggressive performance edge to the graphics but quality will be the primary focus.

Holden's sporty new VE SS

Why do they want to kill the cool performance part of the Holden group? I think that performance groups are pretty gosh darn cool. Maybe they'll put a SVT and say they are closing but they aren't.

Looks like HSV has a real chance to unleash some amazing cars onto the australian market, they have been a pretty smart company in the past given the limitations they had with the previous commodores, if the VE is as good as they say the HSV's will be phenominal, just wish i could aford one lol would be good if they could find a way to let the american market decide if they wanted them to

100kg more weight? That means about 4100lbs or above two US tons on the V8 models. That's about what a '69 5.7L Impala weighed. Progress?

This chassis is "zeta" right? That means our dear, dear Camaro should be the heaviest one in history.

We're getting all this massive displacement and horsepower that dwarfs what you could get in 1960s cars, but it wasn't until Pontiac used its small, 3500lb/1590kg car, the Tempest, with the 6.5L engine that the "supercar" (yes that word was coined to describe the Pontiac GTO, not Ferrari's GTO) was born.

When weight goes up you get a "viscious circle." You have to have bigger wheels and tires to corner the same with greater body weight, but the bigger tires create more running friction and then the fuel economy goes down. The bigger wheels have greater inertia, so acceleration and braking suffer, so then you have to have a bigger engine, then fuel economy takes yet another hit.

One wishes some of the resources that went into creating killer hood scoops and air foils were instead invested in more aluminum and composite parts.

[Rick_VT]

but when u consider how big this car is and the serious amount of safety thats been built into it it cant help but get heavy, but doesnt mean the camaro will be that heavy, they may make it a bit smaller to save weight and i dont know why GM doesnt use more aluminium in its cars to save weight, why cant it as a company buy a serious amount for all its divisions to use to save weight in there cars, im sure they could get a great deal for such a big purchase

[KingElvis]

I've heard that raw steel prices are up significantly - wouldn't that mean the case for aluminum should be better?

I'm sure Holden has produced a fine, world class machine - I just regret that weight increases seem to be a matter of course in redesigns lately.

Yes they Holdens will gain weight but they shouldn't be any heavier than there arch rival Ford ( Falcon ) which currently wheighs about 100kg heavier than the Holden Commodore. And it wont be over 2 ton as the current clubsport weighs under 1700kg. So the new HSV Clubsport should weigh about 185 0kg which is about the same weight as the Ford FPV GT, It will also have more power and more Torque.

Even the Last of the HSV GTS were only 1710kg So the new one should be 1950kg and have around 370kw 600+ nm torque.

Our Holden SS which had 245kw could at 100km or 62mph, just throw it back to 2nd so can you imagine what these cars will be like! i cant wait to find out

[mikmak]

You put your SS into 2nd at 100KPH? You cruel cruel man!

errrrr, no.......

the word 'supercar' was around a while before the Pontiac GTO was released....

the 1954/1955 Mercedes-Benz 300SL was called a supercar...

That's right. There is no way Holden will kill HSV. Besides the image these cars create (BMW alternatives), they make huge $ from the operation. Just expect some pretty good HSVs.

exactly.

better Holdens means insane HSVs.
Holden would never kill off HSV, it brings so much 'street cred' to Holden

[Rick_VT]

Can u just imagine how good the next few series of HSV's are goin to be cause HSV has to be a step above the basic holdens, cant wait to see what the aftermarket guys bring out now to exploit and brand new chassis

[Generation IV]

Yeah guys, the HSVs are going to be absolutely insane. And im gonna say it, and i want to know if anyone agrees with me. FORD ARE ABSOLUTELY STUFFED!!!

[mikmak]

Maybe until 2008. The Typhoon is a pretty convincing performance car at the moment though. And the extra Beef of VE might shrink the focus of the weight of the Falcon and its associated range. Then again no LWB and little in the way of export will surely slap them around a bit. I hope they stage a bit of a come back as its the GM-Ford competition that ensures we get such good product.

[jbernie]

FPV has had the benifits of late... mainly because we are all waiting on the VE and the HSV alternates, you don't wan't a few hundred Z series HSV's ditting on lots and bargain basement prices, there are so many changes with the VE that maybe FPV will win the battle but lose the war, HSV may not be able to get enough cars out this year... lets just wait and see.
