GM’s chief executive was talking green technology in environmentally conscious California on Wednesday, announcing that the nation’s No. 1 automaker is working on a hybrid vehicle that plugs into a standard electrical outlet. Rick Wagoner, during an appearance at the Los Angeles Auto Show, said General Motors Corp. is dedicated to developing alternative fuel, hybrid, electric and hydrogen-powered vehicles.

Mechanically identical to the Tahoe Hybrid that bowed in January of this year at the Detroit auto show, GMC’s Yukon Hybrid is a full hybrid that will have the capability of running on electric power alone at low speeds, unlike GM’s mild hybrids, the Chevrolet Silverado and Saturn Vue Green Line.
