One of the first mass-produced and marketed hybrid electric cars was the Toyota Prius. This pioneering member of the hybrid automotive community was introduced in America in 2001 as a four door sedan with a 1.5 liter inline 4 cylinder gasoline engine with a continuously variable transmission that worked with an electric motor to power the vehicle. The electric motor was recharged with an engine driven generator as well as by the energy reserved when the driving in a coasting or braking mode. This fuel efficient and environmentally friendly technology was still a relatively unfamiliar concept to many motorists in 2001, but with the rising cost of fuel and concerns about the environment, the 5 passenger Prius was gratefully embraced in the United States.

As the years passed, the Prius quickly gained market share with its hybrid technology and family friendly design. The Prius was so widely accepted it was recognized at the North American International Auto Show in Detroit as the 'North American Car of the Year' for the 2004 model year. For the 2004 model year, the Prius arrived in four door hatchback style, further increasing the utility of this relatively comfortable mid size car. The reliable battery back that recharges the electric motor is stowed between the trunk and the back seats and is for the most part physically unnoticeable. However, the fuel efficiency is definitely noticeable, with gas mileage easily averaging over 40 miles per gallon.

As of the 2007 model year, the Toyota Prius is the most fuel efficient car sold in the United States. The two available models are the well equipped base model and the Touring edition, which features a sport suspension system, rear spoiler and 16" alloy wheels. Both models have front seat side and full length curtain airbags as part of the standard equipment package. Reliable, safe and affordably priced, the Prius is a practical and comfortable mid size car that offers hybrid bonuses such as excellent fuel efficiency.
