What is an extended range electric vehicle?

Range-extended electric vehicles (REVs) are a type of hybrid vehicle that combines pure electric drive with a fuel-powered generation system. Their core feature is that the on-board fuel engine charges the battery pack instead of directly driving the wheels, thereby extending the driving range. These vehicles are usually equipped with smaller-capacity power batteries (e.g., 30-50kWh) and can travel 150-250 kilometres in pure electric mode. When the battery is low, the fuel range extender starts automatically to generate electricity, increasing the combined driving range to over 600 kilometres, which effectively alleviates the range anxiety of pure electric vehicles. In the Malaysian market, range-extended technology is particularly suitable for suburban areas where charging infrastructure is still underdeveloped or for long-distance travel scenarios. For example, the models jointly developed by Proton and Geely adopt a similar design. In contrast to battery electric vehicles (BEVs), their refueling method better aligns with the current dense network of fuel stations in the region. Currently, the Malaysian government offers incentives such as road tax and registration tax exemptions for such new energy vehicles, but some range-extended models may not qualify for full subsidies due to the presence of fuel-powered generation units. With the expansion of charging networks and technological advancements, range-extended electric vehicles may become a transitional solution that balances practicality and environmental requirements.
