EREV: Hyundai, Genesis, Jeep, Ram, Ford

An Extended Range Electric Vehicle (EREV) is an electric car driven entirely by an electric motor, featuring a built-in gas engine that acts only as a generator to recharge the battery. [1, 2]

How an EREV Works

Electric Drive: The wheels are turned only by the electric motor. The gas engine never connects to the wheels.
Onboard Generator: When the battery gets low, the small gas engine turns on to make electricity and refill the battery.
Plug-In Capability: You can plug the car into a wall charger or charging station just like a normal electric vehicle. [1, 2]

EREV vs. Traditional Hybrid or PHEV

Traditional Hybrids: Use both the gas engine and electric motor to turn the wheels.
Plug-In Hybrids (PHEVs): The gas engine can drive the wheels directly alongside the electric motor.
EREVs: The gas engine never drives the wheels; it only creates power for the battery. [1]
