While the Prius Prime retains the Prius Liftback's efficient gasoline-electric hybrid drive system, it adds more battery capacity and a charging port, letting it drive as an electric vehicle for up to 25 miles.
Once its electric range is depleted, the Prius Prime automatically switches to hybrid mode, making use of its gasoline engine. Owners can recharge it from a 110-volt wall outlet or from a dedicated electric vehicle charging station.
The hybrid system is comprised of a 1.8-liter four-cylinder engine and a electric motors powered by an 8.8 kilowatt-hour lithium ion battery pack. Toyota says it takes five and a half hours to recharge the battery pack from a standard 110-volt wall outlet.
