Defining EREVs
Extended-range electric vehicles (EREVs) are a new and unique type of electric vehicle (EV) that combines the benefits of battery-powered driving with the flexibility of having a generator on onboard. Unlike plug-in hybrid electric vehicles (PHEVs), which can switch the propulsion between electric and combustion engine, EREVs are powered by an electric motor at anytime.
What is the difference between EREV and Hybrid Cars?
The key difference between EREV and other forms of electric cars is that when the battery depletes, a small internal combustion engine (ICE) kicks in, this intervention is not to drive the wheels directly, but to generate electricity and recharge the battery. This unique setup allows EREVs to maintain the electric driving mode while extending the overall range beyond what a battery alone can provide.
How does EREV operate?
Typically, an Extended-range electric vehicle (EREV) operates as pure electric vehicles for short to moderate distances, relying solely on battery power. However, when longer trips are required, the built-in ICE generator ensures that the vehicle can continue running without needing a charge. This makes EREVs particularly useful in areas where charging infrastructure is limited or for drivers who want the benefits of an EV without the range anxiety.
Additionally, because the wheels are always driven by an electric motor, EREVs and similar to BEVs offer smooth acceleration and quiet operation compared to traditional hybrids. Their design simplifies the drivetrain, reducing mechanical complexity.
Current range for EREVs
Currently, Extended-Range Electric Vehicles (EREVs) offer electric-only driving ranges between approximately 160 to 320 kilometers, significantly outperforming comparable PHEVs, which typically offer 30 to 65 kilometers. EREVs also deliver a total hybrid driving range of around 640 to 800 kilometers, with some models—such as Li Auto’s L9 and AITO’s M9—extending up to 1,315 to 1,400 kilometers, addressing the long-distance needs of consumers without ready access to charging.
Main OEMs providing Extended-Range Electric Vehicle (EREV)
Some of the leading OEMs currently offering Extended-Range Electric Vehicles (EREVs) in the global market include:
- General Motors (GM) – Through its Chevrolet brand, GM has been a pioneer in EREV technology with the Chevrolet Volt, and continues to explore EREV platforms for future models.
- BYD -This Chinese powerhouse is the world’s largest EV manufacturer by volume and offers EREV models like the Qin Plus DM-i and Song Plus DM-i, which blend electric range with ICE backup.
- Li Auto – A standout in China’s premium EREV segment, Li Auto’s lineup (Li L7, L8, and L9) features large SUVs with extended electric range and onboard generators.
- ROX Motor – A rising Chinese luxury SUV brand, ROX offers the ROX 01, a rugged EREV designed for long-range travel. It combines a 1.5L turbo petrol engine with dual electric motors, delivering up to 1,115 km of hybrid range and 235 km of pure electric range—ideal for both urban and off-road adventures.
- Mazda – Mazda has re-entered the EREV space with the MX-30 R-EV, which uses a rotary engine as a generator to extend electric range. It’s a compact crossover that blends Mazda’s driving dynamics with EV practicality.
- Leapmotor – This Chinese EV startup is focused primarily on BEVs, but it has announced plans for range-extended platforms in its future lineup, especially for export markets where charging infrastructure is limited.
- Ram (Stellantis) – Ram is entering the EREV market with the Ram 1500, a full-size electric pickup with a gasoline-powered generator. It’s designed to offer long range and towing capacity without range anxiety—perfect for North American truck buyers.
- BMW – While primarily focused on BEVs and PHEVs, BMW has explored EREV configurations in models like the i3 REx (Range Extender), which was especially popular in urban markets.
