How is a PHEV different than a standard hybrid?
The PHEV has additional battery capacity that allows it to run solely on the electric motor at speeds up to 35 mph until the batteries are depleted. The standard hybrid uses the factory installed on-board battery power and electric drive to operate the car while idling and at slow speeds and to provide additional boost during acceleration. The standard batteries are recharged as the car slows or brakes through regenerative braking.
