Can Extended-Range EVs solve India’s charging problem?

Although EV adoption continues to rise in India, the inadequacies of the country-wide public charging network remain an impediment. And many manufacturers are attempting to work around that impediment, some offering self-charging hybrids, while others introducing plug-in hybrids – neither of which are favoured under the current tax regime.

The electric car’s biggest problem may not be the battery, the charging network or even the price. It may simply be the fact that people still want the freedom to drive 800km without planning where they will stop. That is helping revive an idea that once looked like a technological halfway house: the extended-range electric vehicle, or EREV.

What is an extended range electric vehicle or EREV?

An EREV has a relatively large battery and an electric motor that drives the wheels. When the battery runs low, a small petrol engine switches on, not to drive the wheels, but to generate electricity. Plug it in for everyday driving and it behaves like an EV. On a long journey, petrol effectively becomes a mobile charging station. McKinsey estimates that EREVs can offer roughly 160-320km of electric driving range, compared with around 30-65km for a typical plug-in hybrid, while delivering total ranges of 650-800km. The nomenclature can get confusing in the Indian context, where the term “Extended-Range” is applied to EV variants with a larger battery, offering greater range than the base model.

The idea has found its most enthusiastic audience in China. EREVs and plug-in hybrids grew 79 per cent and 76 per cent respectively in 2024, according to Reuters, as Chinese consumers increasingly gravitated towards electrified cars without wanting to give up long-distance flexibility. Li Auto has arguably been the poster child for the format, having delivered more than 1.4 million EREV vehicles cumulatively by the end of 2025. Its current line-up includes the L6, L7, L8 and L9, with the latest L9 offering a claimed 350km of WLTC electric range and 1,370km combined.

Stop-gap measure or the future of mobility

Almost all Indian car manufacturers have stated that they intend to fully focus on BEVs with the exception of brands like JSW MG Motors, who recently introduced a new PHEV – the MG Hector Tomahawk. JSW MG Motor India unveiled its MG ADAPT architecture in July 2026, and this is specifically designed to accommodate BEVs, strong hybrids, PHEVs and REEVs/EREVs on the same platform. In the EREV configuration, the electric motor drives the wheels while the petrol engine acts solely as a generator.

Think of the Extended Range Electric Vehicle as an inverse plug-in hybrid. Where plug-in hybrids rely on an internal combustion along with a mid-sized battery, the extended range vehicle is by all accounts a conventional battery electric vehicle with a petrol-driven motor that helps generate electricity in real time, thereby allowing for greater highway driveability and making long highway charging sessions

optional. In that sense it consumes less fuel, depending on the usage and that aligns it with India’s intent to reduce its oil-import bill. They also use smaller batteries, which, for a resource-poor country like India.

Are EREVs inherently cheaper than plug-in hybrids?

EREVs can be cheaper to own and run than its plug-in hybrid equivalent, but the answer depends heavily on how they are driven and charged. Their biggest advantage is electric range. With a larger battery, an EREV can cover 150–300km on electricity, allowing many owners to complete most daily journeys without using petrol. A PHEV, typically with a smaller battery, may switch to its engine after 50–100km. A conventional PHEV needs an engine capable of driving the wheels, an electric motor, a transmission capable of integrating the two, and considerably more mechanical hardware. An EREV can use a smaller, relatively simple petrol engine purely as a generator and a conventional EV drive unit. For drivers who charge regularly, therefore, an EREV could deliver lower fuel bills over the course of a year. However, no manufacturer has currently announced plans to introduce EREVs in the country, in the immediate future. Other than MG Motors, BYD is the only car maker with a presence in India, that, in its domestic market, is dabbling in some variation of this technology.

The counterargument is that the larger battery makes an EREV more expensive to buy, and battery replacement could eventually represent a greater financial liability. It also isn’t inherently more efficient when running on petrol. Converting petrol into electricity and then using that electricity to drive the motor involves energy losses, while a PHEV can send engine power directly to the wheels. A PHEV may therefore consume less petrol on long highway journeys once its battery is depleted. In India, taxation could further undermine the EREV’s economics if it is treated as a hybrid and does not receive the favourable GST treatment given to EVs (currently 5%). Ultimately, an EREV makes the strongest financial case for high-mileage owners who charge frequently and do enough urban driving to exploit its larger electric range.

While brands like Hyundai have announced plans to introduce EREVs to markets like the US, they remain committed to increasing their electric portfolio in India, focussing on India-specific, low-cost EVs to increase EV sales share.

EREVs do two things well – potentially lower the up-front purchasing costs when compared to a plug-in hybrid and lower fuel usage if used for last-mile driveability. They also give the owner the luxury of stopping for a charging session according to their convenience and not according to the demands of the battery. In that sense, they offer the best of both worlds. The future may be undoubtedly electric, but EREVs might just help make the journey to full electrification easier.
