Chinese automakers are rapidly transforming the electric-vehicle field, with extended-range models advertised at up to 1,700 kilometers of combined range. This progress signals a strategic push into new markets, especially Europe, where Chinese EVs have grown more attractive on technology and features, with pricing also a draw. The headline combined-range figures describe travel using both stored electricity and fuel-powered generation; they are not equivalent to a battery-electric vehicle’s certified electric-only range.
Unlike conventional plug-in hybrids, Extended Range Electric Vehicles (EREVs) use an onboard gasoline engine as a generator to supply electricity while driving. Electric motors propel the wheels, while the generator can extend travel after the battery’s charge has been used. This layout is designed to retain electric driving characteristics while addressing a persistent concern among buyers: range anxiety.
How EREV Technology Works
EREVs pair relatively large battery packs with an onboard generator. That combination can provide large electric-only driving while extending total distance beyond the battery’s standalone range. The BYD Seal 6 DM-i, for example, is cited with a combined range of 1,505 kilometers, including up to 210 kilometers of electric-only travel before the gasoline engine is needed.
XPENG’s G7 EREV and G6 EREV are cited at up to 1,700 kilometers of combined range, while the X9 EREV is reported at 1,600 kilometers with a 63.3 kWh battery. These headline figures depend on vehicle configuration and test methodology. A useful comparison separates electric-only range from total range and identifies the relevant test cycle: a Chinese-market CLTC combined-range figure cannot be compared directly with a European WLTP electric-range figure.
XPENG’s European configurator illustrates the distinction with battery-electric specifications for the G9L: a 110 kWh gross NCM battery, WLTP ranges of 553 kilometers for the AWD version and 591 kilometers for the RWD Long Range Ultra, and power ratings of 430 kW and 270 kW, respectively. Those WLTP figures measure electric driving range; an EREV’s combined figure also includes travel enabled by its fuel-powered generator.
The technology is attracting attention as Chinese brands expand their European presence. Reuters reported that Chinese automakers including Chery and BYD recorded sharply higher sales in Europe in September, while Geely and SAIC also posted increases. That momentum reflects rising competitive pressure, although sales growth and the technical range claims for individual models are distinct measures.
The Promise of Solid-State Batteries
Chinese manufacturers are investing in solid-state battery technology as a potential route to higher energy density and longer range. Projections of travel beyond 2,000 kilometers on a single charge remain forward-looking targets, often associated with the CLTC cycle, whose results are not directly comparable with Europe’s WLTP figures.
Companies including CATL, BYD, SAIC, GAC and Chery are pursuing next-generation batteries, with some development targets reaching energy densities of 600 Wh/kg. Chery has also set a target of more than 2,000 kilometers per charge for its Omoda and Jaecoo brands. These ambitions reflect the industry’s effort to improve range, charging performance and battery life as the technology moves toward commercial use.
Charging infrastructure is developing alongside battery development. BYD has announced an ultra-fast charging network with power of up to 1,500 kW, paired with its Blade Battery 2.0 technology, and says the system can charge a battery from 10% to 97% in nine minutes. The actual charging experience depends on vehicle compatibility and operating conditions, but the stated figures indicate the scale of investment in reducing charging stops.
Global Impact and Context
The advances are unfolding as the global automotive industry shifts toward electrification. Chinese manufacturers’ development pace has also prompted established automakers to seek local expertise. Volkswagen and XPENG signed a cooperation agreement in 2023 to develop an electric-vehicle architecture for China; Volkswagen said the China Electrical Architecture was completed in 18 months. Reuters has reported that the partnership is part of Volkswagen’s effort to accelerate vehicle development amid intense competition in the Chinese market. The shift is reminiscent of the change facing iconic models like the Mazda MX-5, which, as discussed in this analysis of the last gasoline-powered Miata, marks a broader industry move away from combustion engines.
For consumers, longer combined range can reduce the need to plan around charging infrastructure, while electric-only capability supports shorter trips without running the generator. If the technologies reach mass production, Chinese automakers could help make long-distance electric travel more accessible and raise expectations for what electrified vehicles can deliver.
Solid-state batteries are widely viewed as a potential next step for EV technology, with the prospect of higher energy density and improved safety. Range figures need to be read in the context of their test cycles: CLTC results tend to be higher than WLTP results, and combined EREV range includes generator-supported travel that a battery-electric WLTP figure does not. As emissions rules tighten and competition intensifies, these distinctions will matter to consumers and manufacturers assessing the next phase of electric mobility.
