Following up on yesterday's post/wish list for the Lexus luxury SUV that is powered by a hybrid gas/electric engine, General Motors Canada announced today that it is the first to market in Canada with a truck that uses a hybrid engine. GM is putting a hybrid engine into its Chevrolet Silverado and its GMC Sierra full-size pickup trucks. The products will only be available to its fleet customers right now but should be consumer showrooms by the end of the year.
