In 1997, the Honda Motor Company introduced a two-door gasoline–electric hybrid vehicle—the Insight—to Japan. The Insight’s fuel efficiency was rated at 61 miles per gallon (mpg) in the city and 68 mpg on the highway, and its battery did not need to be plugged into an electrical outlet for recharging. By 1999, Honda was selling the Insight in the US, and winning accolades from environmental groups. In 2000, the Sierra Club gave Honda its Award for Excellence in Environmental Engineering and, in 2002, the Environmental Protection Agency (EPA) rated the Insight as the most fuel-efficient vehicle sold in the US for the 2003 model year.
