Toyota Prius Japan top-selling car for third year Jan 11 08:08 AM US/Eastern TOKYO (AP) - The Prius gas-electric hybrid was Japan's top-selling vehicle in 2011 for the third straight year, underlining how the ecological car has scored a big hit. Sales of Toyota Motor Corp.'s Prius totaled 252,528 vehicles in 2011, the Japan Automobile Dealers Association said Wednesday.
