Toyota Prius
the new Prius (2010 US model year) at the 2009 North American International Auto Show, and sales began in Japan on May 18, 2009. Its new body design is more aerodynamic, with the coefficient of drag reduced to 0.25 Cd. An underbody rear fin helps stabilize the vehicle at higher speeds.
The estimated fuel-efficiency rating using the U.S. EPA combined cycle is: 50 mpg-US (4.7 L/100 km; 60 mpg-imp). The Prius becomes the most efficient car powered by liquid fuel available in the U.S. in 2009, based on the official rating. Only the first-generation Honda Insight (2000–2006) equipped with a manual transmission attained higher mileage. The official UK fuel efficiency data for the Prius T3 is: Urban 72.4 mpg-imp (3.90 L/100 km; 60.3 mpg-US), Extra Urban 76.4 mpg-imp (3.70 L/100 km; 63.6 mpg-US), Combined 72.4 mpg-imp (3.90 L/100 km; 60.3 mpg-US).
The 1.8-liter gasoline engine (previously 1.5 liters) generates 98 hp, and with the added power of the electric motor, total horsepower is 134 hp (previously 110 hp). The larger engine displacement allows for increased torque, reducing engine speeds (RPM) which in turn increases fuel economy at highway speeds. With an electric water pump, the Prius engine is the first production engine that requires no accessory belts, which also further improves fuel economy. The electric motors and other components of the hybrid powertrain are also smaller and more efficient. Toyota estimates the new inverter, motor and transaxle are 20 percent lighter. Disc brakes replace the previous rear drum brakes.
