GM delays new technology diesel
GM has indefinitely delayed the release of one of the most advanced engines it has ever designed amid the current financial woes it is suffering.
The 4.5-litre Duramax diesel engine, which was intended for use in light-duty trucks such as the Chevrolet Silverado and GMC Sierra, featured unique cylinder heads that eliminate the intake and exhaust manifolds. It also had a lightweight block with advanced castings for the crankshaft-bearing journals and oil-circulation system.
"We have to make tough decisions right now," said GM Powertrain spokeswoman Susan Garavaglia.
The eagerly awaited engine was due to have began production this time next year.
