ZF has secured its initial commercial order for the advanced eRE+ range extender technology. Chinese automaker Leapmotor will integrate this system into its upcoming D19 premium SUV, scheduled for launch in 2026. This collaboration marks a significant deployment of hybrid powertrain solutions in the region.
Highlights
- ZF eRE+ technology will debut in the Leapmotor D19 SUV starting in 2026.
- The system combines generator operation with switchable front-axle drive capabilities.
- Peak drive output reaches 200 kW, supporting overtaking maneuvers and all-wheel drive.
- Extended range capabilities exceed 1,000 kilometers while maintaining low emissions.
System Architecture and Performance
The Leapmotor D19 utilizes the ZF eRE+ system, which differs significantly from standard range extenders. Standard units typically function solely as generators to charge the battery. The eRE+ includes an intelligent clutch and differential to enable direct vehicle propulsion.
This architecture allows the system to act as a secondary drive source. Manufacturers can offer switchable all-wheel drive and performance boosts without installing separate components. This approach reduces development overhead and hardware complexity.
Key technical specifications for the D19 application include:
- Generator Output: 90 kW
- Peak Drive Output: 200 kW
- System Range: Greater than 1,000 kilometers
- Components: Electric motor, inverter, software, planetary gearbox, intelligent clutch.
Please note that the internal combustion engine used in this configuration is not supplied by ZF.
Market Dynamics and Strategic Fit
Demand for range-extended electric vehicles (REEVs) is expanding, particularly within the Chinese and North American markets. These systems support new energy vehicle platforms by allowing smaller batteries to be charged via combustion engines during operation.
This technology addresses infrastructure limitations for battery-electric vehicles. ZF leveraged its flexible product range and local production capacities to secure the Leapmotor contract. This strategy aligns with current automotive trends favoring versatile powertrain solutions.
Cost Efficiency and Environmental Impact
The range extender engine operates continuously in its most fuel-efficient power band. This operational efficiency ensures low fuel consumption and reduced CO2 emissions compared to traditional powertrains.
The technology offers several industrial advantages:
- Low platform costs for manufacturers.
- Short development times for new model integration.
- Simplified supply chains by reducing component counts.
ZF views this technology as a bridge between current consumer needs and a fully electric future. It supports EU climate targets by reducing emissions in markets where full electrification faces adoption hurdles.
Industry Context
Leapmotor, founded in 2015, focuses on intelligent electric vehicle design and manufacturing. The company produces high-value components in-house, including electric drives and battery systems. In 2023, Stellantis invested in the company, forming the joint venture Leapmotor International B.V. to expand global distribution.
