Top 20 Rank: 3Toyota has become America's best automaker. Its Camry has been the best-selling car in the U.S. since 2002, and the Lexus LS 430 has been the leading luxury-car brand for seven straight years. The company's long-term strategy is as green as anyone's. Sales of the Prius, which runs on a gas-electric hybrid engine, passed 100,000 units in 2006. The Prius is today as de rigueur in Hollywood as the hydrocarbon-swilling Hummer used to be.
