GM Announce New V8 Diesel

Beginning 2009, GM have announced they will be producing a new small block 4.5L V8 turbo-diesel for the GM Zeta platform - which of course includes our current VE Commodore range. The new tree-hugging engine will churn out 230kW of power with an impressive 700Nm of torque available on tap at just 2,000rpm.
Fuel-efficiency is drastically improved by twenty-five percent and our ozone layer will thank the thirteen percent reduction in CO2 emissions compared to petrol engines in identical vehicles.
While there is no official word on whether this engine will make it into Australian production vehicles, with Australia’s love for the V8 and fuel prices on the rise, it would seem logical that we would see it as part of the Holden line-up in the near future.
To accomodate the new engine, GM have also announced a $100 million upgrade to their Tonawanda engine plant to meet the needs of producing the diesel.

Wow 700Nm of torque. From a GM engine. I would have never thought they were capable of designing something like that.

700Nm of torque is crazy… but ‘tree hugging engine’. 1 year after this engine is released (2010) Honda is supposedly releasing a Hydrogen cell vehicle. Now that is tree hugging… not a V8 which brings fuel consumption down from levels that will deplete the earths oil in 30years now in 39years!

Hope they put that in the Hummer H3
Only problem for GM is they don’t have a 5 speed, car grade auto that will handle that torque
They’ll have to buy the Touareg V10 trannie from VW - that already handles more than 700Nm

4.5L ok not bad but still a massive motor compared to the PSA Peugeot Citroën and Ford developed diesel that gets 199Kw and 640nm from a 3.6L Direct Injection Twin Turbo V8 diesel. This motor is currently used in the 2007 Range Rover. Just hope the PSA DT17 diesel will be put into the Territory!

The PSA Peugeot Citroën and Ford developed diesel V-8 engine is a twin turbo engine. The GM 4.5L V-8 is a single turbo with as you can see from the photo reversed flow heads,the exhaust is in the center V, feedsdirectly into the single VG turbo, and the intake is integrated into the valve cover which have the intercoolers build into them.

The Range rover 3.6 Diesel is a Landrover/Ford project its got nothing to do with the Gemini agreement with PSA and sorry you won’t be seeing in the Territory - 2.7 V6 maybe. Fuel Cells have been Heralded as the new Green Messiah for as long as I have been involved in engine Design 12 odd years, I Have worked with Honda and respect them a great deal but a cannot see anything that will work in the next 12 years especially in the + 1.5 tonne 4 x 4 market. Diesel will be King for the next 10 years But its my job so I would say that wouldn’t I.
