Best-Selling Hybrid Car
To date, the best-selling hybrid car is the Toyota Prius with over 30,000 sold in Japan. The Prius, launched on Oct. 14, 1997, is a hybrid-powertrain vehicle combining a 1.5-liter gasoline engine with a electric generator. The Prius decreased emissions by half, cut smog chemicals by up to 90% and can go twice as far as a standard car on 0.3 gals of fuel. During one Japanese test cycle, the car achieved a fuel consumption of 77mpg.

Most Eco-Friendly Gas-Powered Car
The SULEV-rated (Super Ultra-Low Emission Vehicle) Accord EX Sedan, developed by Honda, has the lowest emission levels of any gas-powered car. A SULEV engine emits only 2.3 lbs of ozone-forming hydrocarbons per 100,000 miles of driving or 86% less than a Low Emission Vehicle (LEV).
