They say good things come in threes. And the third generation of Prius proves to be no exception. Toyota plans to release the latest version of its man-made masterpiece—bigger, faster, and more efficient than its predecessors—in May. The Japanese car company first launched its dual design in 2000, and has dominated the hybrid category ever since. The 2010 update will average 50 miles per gallon, and range in price depending on whether you go with the stripped down style or fully loaded luxury version. With well over one million Prius vehicles currently on the road, and eight of ten Prius drivers satisfied with their purchase, hopes are high for round three.
