General Motors is planning a fall 2007 launch for its highly anticipated so-called “dual-mode” or two-mode gas/electric hybrid version of the 2007 Chevrolet Silverado and GMC Sierra full-size pickup trucks.
Company insiders tell Inside Line the hybrid version of the trucks will see a 25 percent improvement in fuel economy over the conventional trucks, with a combined city/highway fuel economy rating of 25 mpg. The hybrid trucks will also be outfitted with a new V8 engine with an unspecified displacement that makes approximately 365 horsepower and 350 pound-feet of torque.
Both the Chevrolet Silverado and GMC Sierra are capable of using the new hybrid system. It is unclear which truck will be the first to get the hybrid system
