GM delays 4.5L V8 Duramax turbo-diesel engine

It seems like General Motors’ current financial situation is hurting the company’s future advancement that would have provided it a strong ground to compete with its rivals. According to Automotive News, the Detroit automaker has now delayed one of its most advanced engines it has ever designed, the 4.5L V8 diesel for its light-duty trucks.

Yes, truck enthusiasts that were eagerly awaiting the engine are extremely disappointed, but GM Powertrain spokeswoman Susan Garavaglia says the automaker has to make some very tough decisions due to its current financial health.

The new 4.5L V8 Duramax turbo-diesel produces more than 310-hp with a peak torque of 520 lb-ft. It was to debut in the 2010 Chevrolet Silverado and GMC Sierra light-duty trucks. The engine was capable of delivering 25 percent better fuel-economy versus the gasoline engines. It would have raised the trucks’ fuel-economy into the mid to high 20s mpg.

Production of the engine was scheduled to start next fall at GM’s plant in Tonawanda, New York.
