Unlike traditional hybrid vehicles, where both engines work to power the wheels, ZF’s system introduces a small gasoline engine that functions solely as a generator. It activates only when the battery charge dips, recharging the pack without driving the wheels. This allows the engine to operate at a fixed, fuel-efficient RPM, drastically cutting emissions and improving long-term efficiency.

ZF’s approach mirrors previous attempts like the Chevrolet Volt and BMW i3, but modern updates, smarter control systems, and stronger battery tech make it more practical in today’s market. Drivers can still enjoy a full-electric ride for most of their commute, with the added security of extended range for longer journeys, all without relying on large, expensive battery packs.

ZF’s new system will launch in two variants: the eRE and the enhanced eRE+. The base eRE integrates an electric motor with a planetary gearset and inverter, delivering between 93 and 147 hp. For manufacturers needing more dynamic options, the eRE+ includes a smart clutch and differential setup, pushing output up to 201 hp and offering dual roles—either as a generator or an auxiliary drive motor.

This modularity allows automakers to tailor the system to different vehicle types, from city hatchbacks to larger SUVs. As electric adoption rises, ZF’s flexible tech offers a low-cost, scalable way to ease the transition in markets with underdeveloped charging infrastructure.
