Although the electric motor of a PHEV always drives the wheels, EREVs feature an auxiliary power unit, usually an internal combustion engine, that acts as a generator to recharge the battery when it runs out.
An EREV, or Extended-Range Electric Vehicle, is a type of car that combines an electric motor with a petrol or diesel engine. This hybrid vehicle is designed to provide longer driving ranges compared to traditional electric cars.
In the UK, EREVs are becoming increasingly popular as they offer a more sustainable and eco-friendly option for drivers who may have concerns about the limited range of fully electric vehicles. EREVs typically operate on electric power alone for shorter trips, relying on the combustion engine for longer journeys or when the battery is depleted. This technology allows drivers to enjoy the benefits of electric driving while having the peace of mind that they won't be left stranded if they need to travel longer distances.
Additionally, EREVs in the UK often qualify for government incentives, such as reduced road tax and exemption from congestion charges, making them an attractive choice for environmentally conscious drivers.
