You can drive more than 50km for less than $2.00 of electricity.
No. The HEV still has an obsolete very low efficiency, polluting internal combustion engine, with a battery and high efficiency Electric Motor to reduce emissions. They are a half way step towards Zero Emission Battery Electric Vehicle. They are popular at present because they have a longer range than a BEV.
An HEV normally refers to a car that uses both an internal combustion engine (ICE) and a rechargeable battery with a motor/generator, and electronic controller to improve car efficiency and reduce exhaust gasses. With a fully charged battery, a PHEV will produce less emissions, better efficiency and longer range than a HEV.

A battery electric vehicle is a vehicle that uses a rechargeable battery pack, electric motor and electronic controller in place of an internal combustion engine.
