The desire for more diesel vehicles on American roads has become a popular talking point among automotive enthusiasts. We hear about the super-efficient, high performance oil burners cruising all over Europe and don't see any reason that they couldn't work here. After all, their high torque figures and great range would seem like a perfect match for US roads, even if their fuel is generally more expensive than gasoline. It looks like General Motors might be listening, though. Steve Kiefer, the a

The market for midsize pickup trucks has all but been abandoned in the US, but General Motors is about to shake the market up with the all-new (to the US) Chevrolet Colorado and GMC Canyon. Launching next year, GM already told us that its new trucks would be a "fuel-efficient alternative" to fullsize trucks, and aside from the smaller size, Automotive News says that these trucks will accomplish this with a diesel engine.

General Motors and Isuzu have officially stitched together 1.5 million Duramax 6.6-liter diesel engines. The joint venture between the two manufacturers started in 1998, and now the DMAX plant employs 517 workers in a 584,000 square-foot facility. GM introduced the Duramax turbo diesel engine to the US market for the 2001 model year, and it can be found trucks like the Chevrolet Silverado HD and GMC Sierra HD as well as the full-size Chevrolet Express and GMC Savana vans. In its current configur

In February, the specs on Ford's 6.7-liter Power Stroke turbo-diesel V8 were announced: 390 horsepower and 735 pound-feet of torque. A month later, General Motors laid out the specs on its 6.6-liter Duramax turbo-diesel: 397 hp and 765 lb-ft. According to PickupTrucks.com, the Duramax could be shoved to the corner again later this year, when a high-output Super Duty blows out the footlights with 400 hp and 800 – or more – lb-ft of twisting gumption.

Until recently, the only market segment in the United States that had embraced diesel engines was heavy duty pickup trucks. While we were in Maryland this week to drive the 2011 General Motors HD pickup trucks powered by the revised 6.6-liter Duramax diesel V8, we took the opportunity to ask about the now-shelved 4.5-liter diesel. Like Ford and Chrysler, GM was planning to launch diesel engines in its light-duty pickups this year until the economy – and sales – went in the tank.

The move to official automaker support for higher blends of biodiesel has been a slow one. One important step along the way were the establishment of American Society for Testing and Materials (ASTM) standards for B20 (20 percent biodiesel mixed with 80 percent petro diesel) in the middle of 2008. Last year, General Motors announced that the new 6.6-liter Duramax V8 engine would be factory certified to run on B20 sometime this spring. That time is now.

The revamped 6.6-liter Duramax V8 engine will go into production in April 2010 and the current Duramax, which doesn't meet emissions requirements that go into effect January 1, 2010, will cease production the day before the new year begins. In the interim, GM will be retooling the factory and won't be producing any of the engines to go in the Chevy Silverado and GMC Sierra.
