At this year's North American International Auto Show in Detroit, Toyota debuted an entire line of Prius models, including the intriguing Prius C Concept. They still stress that this is a concept, but a small, sporty hybrid hatchback is surely on its way. We can merely hope Toyota is smart enough to retain these design cues, especially as this is meant to be a "fun to drive" hybrid with taut handling and a sub-$20K price. Toyota is promising the highest mileage of any hybrid on the road that isn't a plug-in.
