What Happened
Horse Powertrain has revealed the HORSE D20 Methanol range-extender powertrain, first shown at the Beijing Auto Show 2026. The powertrain is designed for range-extended EVs (REEVs), acting as a reserve power source to recharge the vehicle's battery. It outputs up to 105kW, weighs 170kg, and combines a 2.0-liter turbocharged four-cylinder engine that runs on 100% methanol with power electronics and a generator.

Why this matters
The HORSE D20 Methanol offers automakers a way to build range-extended EVs that run on methanol, an alternative fuel that can be produced from renewable sources and has lower carbon emissions than gasoline. Its compact axial flux motor and high efficiency could make REEVs more practical for buyers, while the technology showcases progress in alternative fuel powertrains.
Terms in This Story
- REEV
- Range-extended electric vehicle; a battery electric vehicle with a small internal combustion engine that recharges the battery when depleted.
- Axial flux motor
- An electric motor where the rotor and stator are arranged as parallel disks, allowing a shorter and more compact design than traditional radial flux motors.
