Like hybrids, plug-in electric vehicles (or PHEVs) have an internal combustion engine and an electric motor. Plug-in vehicles take the hybrid philosophy a step further by installing a larger battery that can be charged externally. The idea is that you can drive short distances, typically 30-60km, using only the electric motor. The engine can add power when needed. When the battery is depleted, electric-only driving is not possible, so the PHEV will switch to hybrid operation. Some PHEVs also allow the driver to select a mode where engine power is used to recharge the battery pack. Because there is a gas tank you can drive anywhere you can go with a gas powered car.

Pros: Can always run on electricity, fuel tank backup for long trips
Cons: The added weight of the engine reduces efficiency, short range of the EV
Good for: People who do very short trips but need flexibility for longer trips
Examples: Mitsubishi Outlander PHEV, Volvo XC60 T8, Range Rover PHEV Vogue, Porsche Cayenne E-Hybrid, BMW 330e
