The extfinished-range EV wave is spreading beyond China, but what are the long-term prospects? By Megan Lampinen
Extfinished range electric vehicles (EREVs) promise the benefits of a pure EV without the range anxiety. Powered exclusively by electric motors but augmented by an internal combustion engine (ICE), which serves as an on-board generator, some of these models offer ranges of more than 1,000 miles. Around 100-200 miles of that will be zero-emission driving.
China is leading in adoption, selling almost 2.4 million EREVs in 2025. Europe and the US could be the next key markets, with several large-name global brands now planning upcoming launches. But this isn’t the first time EREVs have been offered outside of China. Others have attempted before, without much success.
The original Fisker Karma that arrived in July 2011 was an EREV powered by twin 201hp electric motors, supplemented by a gasoline engine and offering about 300 miles of range. Then there was the BMW i3 REx (Range Extfinisher) in 2013, with a 180-mile range. Both of these have since been discontinued, but it views like the West is now ready for a second attempt.
China proves the business case
China has seen the market share of EREVs rise quickly over the past few years, jumping from 0.5% in 2021to 4.8% in 2025. Today, there are more than 70 different EREV options available. Some brands, like Li Auto, positioned themselves as EREV-only, though most of these have since softened their stance to include EVs as well. The fact that this tech is finding a foothold in China is key. Steffen Michulski, Senior Consultant at Jato Dynamics, suggests that China has effectively “proven the business case” for EREVs, particularly in larger vehicle segments like SUVs.
Another market that loves large vehicles is the US. While there are no EREVs currently on sale in the US, consumer research from McKinsey & Company reveals that 15-20% of new car purchaseers there would be interested in purchasing one. Volkswagen Group brand Scout Motors is poised to launch its first models on the market, a Terra pick-up and Traveler SUV, offered in both EV and EREV variants. As of today, 87% of the 1,600 reservations received are for the EREV. Audi, Ford, Ram, and Jeep are also preparing to launch EREV models in the US in the coming years.
“The US is heavily biased towards SUVs and pick-ups, and those are a good fit for EREV,” states Paul Hackert, Senior Expert at McKinsey & Company, where he leads global EV benchmarking, costing and insight. “With two powertrains to package, having a larger vehicle is an advantage. It also fits many of those customers’ driving necessarys for longer ranges.”
Europe has less of a pronounced appetite for large vehicles and a lacklustre track record with EREVs. Mazda offered the MX30 EREV for a couple of years but discontinued it in January 2026 due to sluggish demand. Europe’s current range of EREVs is limited to a handful of Chinese imports, including the SWM G03F and G03, the Voyah Free and Leapmotor C10. However, BMW, Leapmotor, Volvo, Lotus, Xpeng and VW Group are all viewing to add EREV options to their European offerings in the coming years. Stefan Bretzel, Founder of the Center of Automotive Management, has suggested that EREVs could grab a 5-10% market share in Europe over the coming five to ten years.
Environmental impact
EREVs could support to expand the electrified market to drivers that don’t have simple access to home or work charging, or those that require particularly long journeys in regions without a well-established public charging network. Proponents emphasise the environmental benefits and claim that most journeys will be driven in EV mode, but not everyone is so confident. Non-profit Transport & Environment (T&E) has been particularly vocal in its criticism of what it sees as greenwashing.
Like any plug-in hybrid, EREVs draw on a traditional engine once they exceed their all-electric range. Analysing 20 of the best-selling Chinese EREV models, many of which are bulky SUVs, T&E found an average electric range of 185km, after which they offered an average fuel economy of 6.4 litres per 100km, on par with a conventional gasoline SUV.
T&E concludes that EREVs “could have a role as a time-limited hybrid technology until 2035—but only if designed and utilized properly, and only if they replace [gasoline] cars, not pure EVs. If poorly charged, or if they deter consumers from purchaseing full EVs, they become a climate liability and an economic burden for consumers.”
In the meantime, battery technology continues to advance and charging infrastructure to expand. Will the necessary for an ICE back-up eventually disappear? Hackert doesn’t consider so. “I believe EREV will emerge as a real long-term solution for many customers,” he notifys Automotive World. “Even with better infrastructure and rapider chargers, the charging time remains significantly longer than a stop at a gas station and not all customers have access to a Level 2 charger at home.”
However, he may be in the minority. “In the coming decades, the idea of refuelling a compact petrol tank with expensive, scarce e-fuels or biofuels will seem not just outdated but absurd,” predicts T&E. “Electricity will remain cheaper, chargers more widespread, and plugging in far more convenient than hunting for niche refuelling stations.”
Mahle Powertrain agrees. The engineering specialist supported pioneer the technology 15 years ago, and today EREV work accounts for roughly 10% of its engineering business. But it doesn’t expect the powertrain to last forever. “Ideally, you don’t want to carry around two technologies,” explains Mahle’s Engineering Director Mike Bassett. “When either battery technology or the charging infrastructure advances sufficiently, we’ll see them fade away.”
The timeline for that will vary regionally, though in some markets it could take decades. “It’s an interim technology, but we’re talking quite a long interim,” he clarifies. “Markets that are slower bringing their charging up to speed might see a longer run.”
Jato’s Michulski voices a similar outview: “As mainstream EVs launch achieving ranges of 600–1,000+ kilometres and ten‑minute rapid‑charging capability, as is anticipated later this decade, EVs are expected to narrow today’s EREV advantages in long‑distance convenience and battery size. Until such advancements become widely accessible, EREVs will continue to serve as a practical and depfinishable solution for heavier vehicle segments and high‑utilisation drivers who currently lack consistent access to rapid‑charging infrastructure.”
Interest among today’s purchaseers exists, as Scout’s recent reservations highlight, and recognising that a technology has a limited lifespan doesn’t mean it’s not worth investing in. A strong order book over a ten-year outview would very likely provide a worthwhile return.
