Toyota Motor Corp. (TYO:7203) was the first automaker to mass produce a hybrid, and the Prius remains the most popular one on the market even as competing brands are beginning to grab market share. Now the world's largest automaker is bragging that its Prius plug-in hybrid hit the equivalent of 581 miles per gallon on Germany's famous Nürburgring Grand Prix-style race track, known as the "The Green Hell" for its challenging curves and steep climbs in the forests 75 miles northwest of Frankfurt.
