ZF’s newly developed range-extender architecture consists of two variants: the eRE and eRE+. The former combines an electric motor, planetary gearset and integrated converter. The latter adds a clutch and differential, enabling it to serve as both a generator and a secondary drive source. Output of the combustion engine ranges from 148bhp to 201bhp.
The results, BMW claims, are a 30% increase in range, a 20% uptick in efficiency and 30% faster charging. Production costs are also 50% less, it has said, suggesting potential for lower prices in the showroom too.
Munich looks to Li
Among the key drivers behind BMW’s decision to revisit the range-extender is the meteoric rise of Chinese car maker Li Auto. Founded in Beijing in 2015, it has taken a leading role in the technology and currently offers four models with a range-extender drivetrain: the L6, L7, L8 and L9 (below).

Li Auto’s global sales surged past 500,000 in 2024 and the company has set an initial target of 700,000 for 2025.
NMC battery technology for BMW’s new range-extender drivetrain is said to be under development in partnership with CATL – the same Chinese-based automotive battery specialist used by Li Auto.
All of Li Auto’s existing range-extender models offer a range beyond 600 miles. The L9, which comes with the option of a 52.3kWh battery, manages up to 731 miles on the CLTC test cycle.
