As has become tradition, our editors compiled a list of every new or substantially revised vehicle, assigned them to their respective categories based on factors such as segment and price, and deleted vehicles not driven by at least one editor prior to voting on Nov. 12, 2007. Except for contenders in the Best Car for the Environment, Best Family Car, and Best Car for Teen Drivers categories, all vehicles must have been introduced for retail sale during the 2007 calendar year. Each editor voted for the vehicle they’d most often recommend, with winners determined by a simple majority.
