The Prius is a complex car that has been thoughtfully designed. The Prius combines an electric motor with a highly efficient combustion engine. The Prius incorporates a new type of transmission that does away with the conventional 'gears' and uses a sun and planets type transmission. This reduces problems that are often faced in conventional transmission since there is no changing of gears. The set-up allows for a smooth transition from high torque to high revolutions per minute. The design also allows for the electric motor and gas engine to work together effectively or allow the electric motor to propel the car without the gas engine running. For more information about how the Prius works visit Graham Davies web site. He put together a very informative web page that is easy to understand and has many illustrations to help in understanding the concepts of the Prius.
Those who have purchased the Prius have loved it, and I am one of them. The cost for the Prius is almost the same as the Camery which is the only Toyota vehicle that is close to what the Prius offers in features (except for the Hybrid components of course). John's website also has a lot of wonderful general information about the Prius.
