The first-generation Prius, a five-passenger model, was introduced to the States in 2001 (its arrival made it the second mass-produced hybrid, after the two-seat Honda Insight). The second-generation model arrived in 2004, followed by the current third-generation design that arrived for the 2010 model year. The automaker has subsequently added the Prius V, a hatchback wagon (shown above) and the Prius C, a subcompact hatchback. As of March, 2013, cumulative worldwide sales of the Prius had reached 3.67 million units.
Last year, Toyota sold 236,659 Prius models in the US. However, sales of the model have fallen 5.1 percent in the first six months of 2013. In response, the automaker has boosted its marketing for the model, and the promotions are expected to continue through at least July.
