Hybrid vehicles and SUV variants
A hybrid vehicle is http://www.purevolume.com/listeners/abidingaccuser421/posts/4408369/Cars+%3A%3A+John+Leigh+Wins+Lifetime+Achievement+Award - http://www.purevolume.com/listeners/abidingaccuser421/posts/4408369/Cars+%3A%3A+John+Leigh+Wins+Lifetime+Achievement+Award - a vehicle that uses two or more distinct power sources to move the vehicle. The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors. When the term hybrid vehicle is used, it most often refers to a Hybrid electric vehicle. These encompass such vehicles as the Lexus RX 400h and 450h and others. A petroleum-electric hybrid most commonly uses internal combustion engines (generally gasoline or Diesel engines, powered by a variety of fuels) and electric batteries to power the vehicle. There are many types of petroleum-electric hybrid drivetrains which offer varying advantages and disadvantages.The Lexus RX 450h, which went on sale in mid-2009, is a hybrid vehicle. It is equipped with a 3.5-liter 2GR-FXE V6 engine, now running on the Atkinson cycle, which produces 245 hp (183 kW); by incorporating a more powerful inverter and electric motors, total horsepower reaches 295 horsepower (220 kW). Two additional systems are added to the RX 450h's Lexus Hybrid Drive powertrain, an exhaust-heat recovery system to reduce engine warm-up periods (optimizing engine start-stop times), and a water-cooled Exhaust Gas Recirculation (EGR) system to reduce engine pumping losses.
