Unnamed GM officials told Bloomberg that the also unnamed hybrid could be "ready in time for the Detroit auto show in January," and that any commercial production is at least a year away. The vehicle will get more than 60 mpg and plug into any outlet.
Officially, GM had no comment on this rumor, but it is convenient that the news slipped out today, just a week before the film "Who Killed The Electric Car?", which is critical of GM, opens in theaters.
