Toyota announced the arrival of the four-generation Prius just last year, but of course, there’s always room for improvement, especially in the face of rapid advances in the world of all-electric transportation.

So how do you develop an industry leader without screwing up the formula? Enter the Prius Prime. Framed as the “ultimate” iteration of iconic gas-sipper, the Prime bears a new aesthetic, even more standard tech, and a revamped, hyper-efficient plug-in powertrain.
