A new power option is available on the G2500 and G3500 Express Cargo Van models for 2006 with the arrival of the new Duramax 6600 turbo-diesel V-8 engine. It is the only diesel-powered engine offered, and its 460 lb.-ft. of torque is far more powerful than any of the gasoline engines available for the Express.
