Side by side comparison of Toyota Prius Liftback (left) and Prius v (right). The Prius v powertrain uses the same 1.8 liter Atkinson cycle gasoline inline-four engine used in the conventional Prius, a 60 kW traction motor, and shares the Prius's Hybrid Synergy Drive system and the same 201 volt nickel-metal hydride battery pack.
