GM plans first light-duty clean diesel V8 for North America

Tonawanda, New York – General Motors has announced it will introduce a new 4.5-litre V8 Duramax turbodiesel for North American light-duty trucks and the Hummer H2 built after 2009. The new engine improves fuel efficiency by 25 per cent, reduces CO2 emissions by 13 per cent, and cuts particulates and NOx emissions by at least 90 per cent.

The announcement was made in conjunction with news that the company will invest US$100 million in its engine plant in Tonawanda, New York to build the new engine.

The diesel engine will fit within the same space of a small-block V8 gasoline engine, thanks to integral exhaust and intake manifolds and a narrow block. It is expected to achieve ratings in excess of 310 hp and 520 lb-ft of torque. “This new GM light-duty diesel is expected to become a favourite among customers who require excellent towing ability and fuel efficiency,” says Tom Stephens, group vice president, GM Global Powertrain and Quality. “It will meet the stringent 2010 emissions standards and it will be compliant in all fifty states, making it one of the cleanest diesel vehicles ever produced.”

The engine plant investment will include a facility renovation, new machinery, equipment and special tooling. The company will also invest an additional US$41 million for vendor tooling, containers and investments at other locations to support the Tonawanda operations. Construction at the plant is slated to begin later this year, with engine production expected in the fourth quarter of 2009. The investment follows an earlier announcement of US$300 million for production of an all-new, DOHC V8 engine for luxury cars and SUVs, which will also commence in 2009.

The Tonawanda plant, which opened in 1938, currently builds engines for the Chevrolet Cobalt, HHR, Colorado, Malibu and Impala, the GMC Canyon and the Hummer H3, as well as 8.1-litre V8 engines for the Chevrolet Kodiak and GMC TopKick medium-duty trucks.
