GM to Introduce New Light-Duty Diesel for North America
High-efficiency V-8 scheduled for pickup trucks under 8,600 pounds Gross Vehicle Weight
MILFORD, Mich. - General Motors Corp. will introduce a new V-8 turbo-diesel that improves engine fuel efficiency by 25 percent for North American light duty trucks after 2009.
The premium V-8 diesel is expected to deliver class-leading torque, power and refinement while maintaining a significant fuel efficiency advantage over comparable output gasoline engines.
The new dual-overhead cam, four-valve V-8 diesel engine will fit within the same space as a small-block V-8 gasoline engine. This compact size is made possible by using an integrated air system and narrow block.
"This new GM light duty diesel is expected to become a favorite among customers who require excellent towing ability and fuel efficiency," said Tom Stephens, group vice president, GM Powertrain. "It will meet the stringent 2010 emissions standards, and it will be compliant in all 50 states, making it one of the cleanest diesel vehicles ever produced."
Environmental benefits of the new engine include a 13-percent reduction in CO2 versus gasoline engines, and at least a 90-percent reduction in particulates and NOx compared to diesel vehicles today. This will be GM's first engine to use a NOx after-treatment system with a diesel particulate filter to help achieve the Tier 2 Bin 5 and LEV 2 emissions standards.
Technical highlights of the engine include aluminum cylinder heads with integrated manifolding, compacted graphite iron (CGI) block for a strong engine base and fracture-split main bearing caps and connecting rods for a precise fit. A high-pressure, common-rail fuel system is used, which has the ability to inject fuel five times per combustion event to control noise and emissions.
GM (Opel, Saab, Vauxhall, GMDAT, Isuzu and Suzuki) currently offers 17 diesel engine variants in 45 vehicle lines around the world. GM sells more than one million diesel engines annually, with products that offer a range of choices from the 1.3L four-cylinder diesel engine sold in the Opel Agila and Corsa, up to the 6.6L V-8 Duramax diesel sold in full-size vans, heavy duty pickups and medium duty trucks in the U.S.
GM introduced the Duramax diesel 6.6L V-8 in the U.S. in the 2001 model year and since then, customer enthusiasm for this heavy duty diesel has been outstanding.

I can't wait to see how it works out. They've needed a diesel in the light duties for a long time. I wonder what kind of tranny choices will be offered.
I'd like to see a small Alison coupled with it.
