This plug-in hybrid concept debuted at the Detroit auto show in January. It's a break from the Prius family, with a lower, more futuristic design. The midsize vehicle has touchscreens that operate like smartphones and a "Human-Machine Interface" system that the company says can learn driver preferences and habits. It is intended for a global market by 2015.
