Holden confirms a 260kW 6.0-litre V8 and an upgraded Alloytec V6 from next month

By MARTON PETTENDY 13 December 2005


IT’S official: Holden has confirmed it will replace its current 5.7-litre Gen III V8 with a more powerful and more efficient 6.0-litre version within two weeks.

Holden boss Denny Mooney said that from 2006 Holden’s staple V8 will become a 260kW/510Nm version of General Motors’ new 6.0-litre Gen IV.

"We are going to come out with a 6.0-litre V8 this year," he said. "We're happy to take another step with our V8. We think it's just a good move from a refinement standpoint.

"(It has) good, strong, low-end torque that people that buy V8s want and enjoy ... the right balance between economy power and refinement."

Holden’s GM-sourced Gen III V8 joined the Holden range in June 1999 with the release of the VT II Commodore line-up, in which it offered 220kW/446Nm. It replaced Holden’s long-running 5.0-litre V8, which delivered 195kW/430Nm in its final form.

But the Gen III doesn’t meet Australia’s strict new Euro III-based 2006 emissions regulations, and it’s believed adopting GM’s new V8 was more cost-effective than upgrading the Gen III.

As reported by GoAuto two weeks ago, many Holden dealers are already taking orders for Gen IV V8-powered models, stocks of which will be in dealerships by the end of December.

Codenamed L72 but dubbed "LS1.5" by Holden insiders, the 6.0-litre Gen IV continues the all-alloy, two-valves-per-cylinder pushrod design of the Gen III, but differs from the Gen IV LS2 6.0-litre V8 that powers the new Corvette Z06 and HSV’s local line-up, in which it produces 297kW.

"It will not be the LS2," said Mr Mooney. "It's actually a lower power version ... of the Gen IV V8. It's got a milder camshaft. It's not meant to be the HSV kind of performance level."

Introduced in its North American SUV line-up this year and originally expected to make its local debut in September’s all-new VE Commodore, GM’s fourth-generation pushrod V8 differs primarily in its employment of variable valve timing and Displacement On Demand (DOD) technology, which is claimed to reduce fuel consumption by up to seven per cent.

Combined with GM’s new 6L80 six-speed automatic transmission, which is claimed to reduce fuel consumption a further four per cent and improve 0-100km/h acceleration times by up to seven per cent, Holden’s new V8/auto combination should be more powerful, smoother and at least as economical as the Gen III.

The Gen III currently powers Holden’s Monaro, SS and SV8 sports flagships and its top-shelf long-wheelbase Caprice (in 250kW guise), and is optional in Calais (with 235kW), Berlina and Statesman (in 245kW form).

It’s not known whether Holden will continue to offer V8 versions of its all-wheel drive Crewman Cross8 and Adventra LX8 models in 2006, when the new V8 will power an otherwise unchanged VZ Commodore range for eight months before the new VE Commodore sedan is released.


Revised V6 for 2006 too
HOLDEN’S Port Melbourne-built Alloytec V6 will from next month gain on-board diagnostics, an upgraded catalytic converter and an extra knock sensor.

Reflecting the cost of meeting Australia’s so-called Step II emissions requirements for 2006, the Alloytec upgrade comes after just 16 months of service in VZ Commodore.

The same upgraded 3.6-litre V6, but with a higher torque output, will next year also appear in Holden’s Thailand-built Rodeo utility. Rodeo’s new V6 will offer more performance and better fuel economy than the Isuzu V6 that’s no longer required for use in Frontera and Jackaroo models.

sweet :eclipsee_

Gen 3's wont be worth much now....god help the old 5 litre...slow as hell by todays standards

Does that say 6 Speed auto? Holden have been VERY quiet about it if they are going to be releasing a 6 Speed auto, as Ford 'told' everybody as quickly as they could when the ZF was finalized.

Why would I fear Windsors? They have been laid to rest. Are you saying that they may come back as ghosts to haunt me?

You should be, it will keep the same status quo that the Gen3 has, that is to say, magazine will sing the Ls1.5's praises above the Boss. You watch.

Thumbs up to Holden, however if they are going to keep the 250kw in stock form for a 6.0L then this is pretty disapointing considering the Gen3 does that now. Of course, there is more to the engine than the kw, the .3 difference will probably ad a little more torque and it should have some good aftermarket mods.

260kW, 510Nm which means it trumps the BOSS260 (the ECE vs DIN issue would mean it is really about 266kW by the same measure as the BOSS) and is lighter.

The question mark remains over the Adventra, Crewman, Cross8 variants which are currently at a lower state of tune than the sedans and ute. If, as I have read elsewhere, they are going to run the same power across ALL variants it would suggest that the 6.0l is seriously detuned as the above mentioned models do not have the space for the same exhaust setups as the mainstream models. This new engine is going to have a lot of legs and expect it to go up to 265/270kW for VE in line with regular Holden practice.

hasnt it been shown that holdens theory on that isnt as good as they made out ? as motor dyno'd a boss 290 and a LS2 and they both produced 226RWKW
could be wrong

When you have so many thousands of cars to shift you tend to keep quiet about major updates/upgrades...hence the official press release within weeks of the actual model changes

....."we have good news but can't tell you too far in advance until we get rid of our massive stockpile"...

Ford is not in the same boat and with the lack of exterior changes from BA to BF needs to push the mechanical changes, fuel economy gains & NVH improvements as much as possible.

That being said, can we say that our Gearbox is better than theirs? Ours comes out of Germany, and theirs is out of where?

From GM Powertrain / Hydramatic, the people who invented the modern torque-converter auto. Where it comes from means diddly.

It *could* be argued that GM / Holden are using their own developed and built transmission whereas Ford have had to use an outside supplier.

It is well known that the ZF is a very good box, but it doesn't automatically mean the GM unit is bad. The 6L80 is very similar in design and sophistication to the ZF and while the codename may sound similar to the older generation units, it is a brand new clean sheet design. From what I have read it also has a superior torque rating of 750Nm compared to 600Nm for the ZF.

Holden buy it from the US, how have they done any development and building of the auto. They just take them out of the box and fit them. The ZF is still way ahead of the GM 6 speed.

There are many different version of the ZF trans. We get just two of them. BMW 7 Series V12 has 776nm with a ZF trans, so I would imagine that version would be able to hold atleast 800nm safely.

It definately will be interesting in the next few years to see how the 6L80 will stand up to the ZF.

haha nicely done
still, my push bike is faster, just ask the legoman

[RavenLS1]

sounds like a nice ugrade for holden looks like it should be a nice donk.

[sbcb]

Wonder if the piston slap is sorted?

[T_Terror]

Thats really hot news, i would seriously look at a VZ if the rest of the car was up to scratch.

[FPV]

Ford have got one of the world's best automatic tranmissions in there, thats just a fact. It doesnt matter that they have sourced it internally/externally, they have gone out and got the best they can get to develop the falcon into a better world class car. To prove that they have got the best you will find the transmission in Audi's,BMW's and Jaguar, the list goes on.

However the 6L80 should not be based on previous transmissions such as the 4 speed hydramatic, i don't think it would be acceptable to build a 6 speed transmission for use in the Cadillac STS-V if it was to have similar traits to the 4 speed. We will just have to wait and see when holden gets there transmission, how it will go against ford's.

[Laminge]

AWD anyone?

[red_hotxr6]

Obviously the old engine cant keep up with the ford powerplants.

Pity they dont haul on the track, go craig. : :

If that is your line of thinking then you are seriously misinformed. :MrT_anim:

[XplosiveR6]

Who cares, its just another crate motor holden has dumpt streight into the commodore from Chev, im sure if ford dumped the GT motor streight from the US in a falcon into would be a screemer too. When holden actually engineer something for themselves then ill be impressed.

[HSE2]

Have to give credit where it is due. Holden with its vast access to engine options have been able to address emissions standards while improving the breed simultaneously. Certainly sounds like a nice unit.

[HRT8]

What started out as an informative post has, like usual ended up with some very small minded people rubbishing products no-one has even sampled.
Who cares where the motor or gearbox for that matter comes from. Its the competition between the two big car makers that benefits us as consumers in the end.

Competition gives us far better end products!

Phew, the voice of reason at last. Agree 100%

l want the best car for my money not the one that has the most "in house" gearbox FFS! l agree with HSE2, seems like a good move, improve the engine offering and meet the new emmisions standard. Where's the downside :
