The original Prius hit the streets of America back in 2000 with its Corolla-like looks and a funky hybrid-electric drive that was unlike anything else on U.S. roads except the two-seat Honda Insight. That first-generation Prius was replaced in 2004 with the familiar hunchback turtle look we’re all used to. The second generation is where Toyota really gained ground with hybrid sales, moving over 600,000 cars before the third-generation Prius took over in 2009. With the new model, the Prius gained a few reshaped exterior panels and a more futuristic interior while retaining is stellar fuel economy numbers. Since then, Toyota has moved over 710,000 third-gen cars.
