Chevrolet certainly had their fun teasing us with details before the unveiling of the new Malibu. Even though we now know what the new model will look like, Chevy is still at it letting out details a few at a time. They have now announced that the 2013 Malibu will have trim known as Eco, which will share the eAssist mild hybrid system with the LaCrosse and the Regal. It will also have the usual drag-reducing accessories, and Chevy says it will achieve 26/38mpg.
