For the environmentally conscious, the 2003 Toyota Prius offers better-than-excellent EPA estimates coupled with the convenience of five passenger seating. The Prius is a Hybrid vehicle featuring a 4-cylinder gas engine and electric motor combination under the hood. The engine generates 70 horsepower from a 1.5-liter gas/electric inline 4-cylinder mated to a 1-speed CVT automatic transmission. EPA estimates peg the Prius in the 52 City/45 Highway range. The Prius comes nicely equipped with auto climate control, cruise, keyless entry, power accessories and AM/FM/CD audio.
