“DETROIT — Steve Kiefer, General Motors’ vice president of global powertrain, said he is considering a diesel engine for the light-duty Chevrolet Silverado and GMC Sierra to counter fuel economy improvements due on the Ford F-150 and Ram pickups.
He also said GM engineers are working to improve the cylinder cutoff system already on the trucks. The system turns off half an engine’s cylinders when the vehicle is cruising.
The good news for GM is that it has a diesel for its pickups ready to go. GM engineers designed a 4.5-liter diesel V-8, but the project was put on ice when the company spiraled into bankruptcy in 2009.
“We are looking closely at diesel entrees in that segment,” Kiefer said. “In fact, I heard the term ‘dust off’ that 4 1/2-liter at one point. That is certainly one of the options. Clearly, we have a portfolio of diesel engines.”
The 4.5-liter V-8 was to be built in GM’s Tonawanda, N.Y., engine plant. GM had gone as far as clearing factory floor space and installing the transfer lines in 2008.
Though the engine was advanced for its time, with a single turbocharger mounted between the cylinder heads and other innovations, GM would likely redesign the engine — possibly reducing displacement — and adopting the latest friction reduction technologies.”
I’m not trying to bring something up that is dead, I really liked the fact back in 2008 when they were going to produce a light duty diesel for the half-ton and they should have, but we all know they should have done it already so heres to hopefully they will.
