HYBRID ELECTRIC VEHICLE
HEVs combine gas engines with electric motors to generate electricity as you drive, which also means they never need to be plugged in.
PLUG-IN HYBRID ELECTRIC VEHICLE
PHEVs operate in the same way as HEVs, but can optionally be plugged in for extended electric-only range.
HYDROGEN FUEL CELL ELECTRIC VEHICLE
FCEVs use hydrogen as an energy source in conjunction with electric motors, emitting water as the only by-product from the tailpipe.
