ZF has announced that Chinese automaker Leapmotor will integrate its advanced eRE+ range extender technology into a version of the D19 premium SUV, starting in 2026. The eRE+ system enables generator operation and also supports switchable front-axle drive for all-wheel-drive capabilities.
The eRE+ technology is built around an electric motor featuring an integrated inverter, accompanying control software and a planetary gearbox. Unlike ZF’s earlier eRE—which functions solely as a generator—the eRE+ adds an intelligent clutch and differential, allowing the unit to act as a secondary drive as needed.
This system delivers a generator output of 90 kW and supports a peak drive output of 200 kW, providing additional boost for overtaking and dynamic driving situations. ZF says that this enables the Leapmotor D19 to achieve a total range greater than 1,000 kilometers. The specific combustion engine utilized in the range extender system is not supplied by ZF.
The eRE+’s ability to operate the engine within its optimal efficiency band is designed to keep fuel consumption and carbon dioxide emissions low. According to ZF, the platform delivers switchable all-wheel drive without the need for separate, dedicated components, potentially reducing both development time and supply chain complexity for automakers. Target markets identified by ZF include automotive manufacturers in China and North America focused on expanding their range-extended electric vehicle offerings.
“Range extenders are currently in increasing demand, especially in the Chinese and North American automotive markets,” said Sebastian Schmitt, head of ZF’s Electrified Drive Technologies division. “We responded to this demand in good time with a flexible range of range extender technology and local production capacities. This strategy has borne fruit and led to our new order for Leapmotor,” said Timo Meisel, Senior Vice President of Electrified Powertrain Technology Division, Asia Pacific.
