According to Automobilwoche, BMW is evaluating the feasibility of mass-producing range-extender electric vehicles (EREVs), a move that could significantly enhance its electric vehicle (EV) performance in the Chinese market.
The German automaker has reportedly tested a range-extender system on an iX5 prototype, which internally is dubbed the “iX5 REx.” With a small internal combustion engine dedicated to charging the battery, the vehicle is said to achieve a range of up to 1,000 kilometers.
Autocar previously noted that BMW’s renewed interest in range-extender technology stems from the rapid global growth of EREV sales, particularly in China—BMW’s largest single market. Chinese consumers have shown increasing preference for EREVs, which address range anxiety by combining electric propulsion with a backup fuel-powered generator.
While BMW has long focused on pure EVs and plug-in hybrids, the competitive landscape in China’s EV market—dominated by local brands and characterized by evolving consumer demands—has prompted the automaker to reconsider diversified powertrain strategies. Range extenders could position BMW to better compete in segments where EREVs have gained traction, such as premium SUVs.
Industry analysts suggest that if BMW proceeds with EREV production, the technology could first debut in the next-generation X5, leveraging the model’s popularity in China. The move highlights BMW’s efforts to adapt to regional market dynamics and strengthen its foothold in the world’s largest EV market.
