General Motors has released official details on its new 4.5L V8 Duramax turbo-diesel engine which could feature in the Holden Commodore line up by 2010.

The new V8’s compact size enables it to fit within the same space as petrol units, offering GM the flexibility to introduce it in a wide variety of vehicles to meet market demand and new CAFE regulations.

It is expected to deliver 231kW of power and an enormous 705Nm, returing a 25 percent improvement in fuel efficiency over comparable petrol engines.

The environmental benefits of the new engine include a 13-percent reduction in CO2 emissions and at least a 90-percent reduction in particulates and NOx compared to many diesel vehicles today.

“This new V-8 diesel meets the toughest emissions requirements in North America, and it also delivers an effortless performance feel because of its high torque across the speed range,” said Charlie Freese, executive director of GM Powertrain Diesel Engineering.

If it works in the Commodore, they will we see it in the G8 or the Park Avenue?

or even.... gasp, the Camaro?

[Slick_Holden]

Does anyone really think this will be coming?.
Performance like this form a diesel is insain!..

Option 290kw 560Nm V8... Or 4.5lt V8 Turbo Diesel 231kw 705Nm..

Maybe other way around, If it works in the G8 and is wanted that gives Holden reason enough to do it, Either way they will be testing it out from go to wo.
So it will be all good for everyone.

It would work great, if a little heavy, as a high performance engine in cars but the new 2.9L V6 diesel coming out of Europe would be a better match for most people and offer much better fuel economy I would guess. Depends on your priorities. I'd love a G8 with the 2.9L.

With diesel fuel close to $4.50 I don't see no benefit. So what I will get 35mpg in my G8 for example and pay high diesel fuel costs. Yup that saves me money. With more diesels on the road it will give oil companies an incentive to raise diesel prices even more.

The success of the Audi R8 TDI will determine if we get a performance car with a duramax. I for one think it would be awesome. Better mileage and tons more potential for tuning ect.

VE Cross8 plus this thing = maximum WIN.

Chuck it in a Rodeo too .... that will knock the socks of the TRD Hilux

[skylark68]

The diesel option would probably be prohibitively expensive combined with high diesel fuel costs = no go. I'll stick with gasoline.

Agreed - I'd much rather see a V6 diesel in the Commodore/G8 instead of the Duramax...

...however, the 4.5 liter Duramax would be nice in a performance variant, if they were so inclined!

Given the added weight over a diesel, the 4.5L would be more at home in a RWD Lucerne/DTS. Adding that much weight to the nose would make a RWD car "push like a dump truck" to quote Ward Burton.

[prototype66]

It would work well in the Lambda vehicles as well. Hopefully more bio diesel will be available soon.

Don't worry gasoline will soon catch up to diesel prices.

[Slick_Holden]

Might be good for HSV and LWB models of holden to export into Europe and the middle east with this TD?.
They say it's what is missing maybe right now?.

Yeah, it will and Diesel will also go up. Diesel fuel use to be less expensive than gasoline. What happened?
