GM (GM): The Diesel Goes Green

GM (GM) is investing $100 million in a new plant to build reduced carbon-dioxide diesels that are also more fuel-efficient than current models. "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," said Tom Stephens, GM’s vice president of global powertrain and quality.

While the new engines will initially be put into SUVs and pick-ups, the technology may give the company a leg up on "greener" vehicles and could eventually be used in cars.

Perhaps the hybrid is not the wave of the future.
