General Motors plans to offer diesel-engine cars under the Cadillac and Saturn brands in the U.S. by 2010, industry journal Automotive News reported, citing a source familiar with the plan, according to Reuters.

In a video blog on the company’s website dated Thursday, GM Vice Chairman Bob Lutz confirmed the top U.S. automaker would use clean diesel engines in passenger cars, sport utility vehicles and other light-duty trucks.

He stressed, however, that emissions hardware and control systems needed to meet the standards would add another $2,000 to $2,800 to the $1,000-$2,000 premium that already exists for diesels over gasoline-engine cars.
