With the number of eco-conscious people increasing by the day, all automobile manufacturers are now forced to step into the hybrid market. While some are already into manufacturing fully hybrid versions, companies like GM Chevrolet came out with the hybrid version of their Silverado that was marketed as a “mild” hybrid. The company is all set to launch a fully hybrid pickup truck as well to be in tune with the ever growing demand for hybrid trucks. GMC Sierra, a full size hybrid pickup truck, would also be offered on sale in early 2009. Ford’s F-Series also employs hybrid technology to offer fuel economy to its patrons.
