Lutz claims on an Internet posting that the U.S. buying public dictates what the automakers build. American drivers usually prefer vehicles with larger engines, often in vehicles larger than they really require; trucks and SUVs have been a large seller for both American manufacturers and imports. However, many import brands have "credits" stored up from previous years that help them meet the current CAFE requirements that the domestic brands do not posses. The CAFE standards currently peg any given automakers trucks at 20.7 mpg, with cars at 27.5 mpg.
General Motors has been playing a game of catch-up lately with hybrid vehicles, selling far fewer than Toyota, Honda or even their Detroit rival Ford. Additionally, many of the latest vehicles released by the automaker have been SUVs and their new line of trucks -- vehicles which make up the majority of vehicles sold in America. Toyota is poised to release the newest version of their full-size pickup, the Tundra, in the coming year. However, Toyota sells far fewer trucks in America than does General Motors.
