HORSE D20 Methanol Range Extender Powertrain Debuts for REEVs with 105 kW Output

Horse Powertrain introduced the HORSE D20 Methanol range extender powertrain on July 14, expanding its portfolio of propulsion technologies for range-extended electric vehicles (REEVs). The integrated system weighs 170kg and combines a motor, power electronics, and a 2.0-liter turbocharged four-cylinder engine into a compact package capable of delivering up to 105 kW of output. The solution is engineered to improve driving range while supporting electrified vehicle architectures without changing its core technical specifications.

Designed for 100% Methanol Operation

The HORSE D20 Methanol powertrain features an engine engineered to operate using 100% methanol fuel blends. A 240mJ high-energy ignition system enables ultra-lean combustion inside the cylinders while also allowing reliable pure-methanol cold starts at temperatures as low as -35°C. The engine's nitrogen oxide (NOx) emissions comply with China's CN6b standard of 35mg/kWh and consequently satisfy the Euro 7 requirement of 60mg/km, maintaining the stated emissions performance.

Axial Flux Generator Improves Efficiency

An all-new generator architecture has been integrated into the powertrain through an axial flux motor mounted directly on the engine crankshaft. Compared with conventional solutions, the axial flux motor is 46% shorter while producing 63% more kilowatts per unit of volume. The motor delivers an electrical efficiency of 96.4%, contributing to improved overall system performance while preserving the original engineering characteristics announced for the powertrain.

Performance and Battery Charging Capability

Laboratory testing indicates that the HORSE D20 Methanol achieves a fuel-to-energy conversion ratio of 47%. According to the announced performance figures, the system can completely recharge a 40kWh electric vehicle battery using only 19.6 liters of methanol fuel. These specifications position the powertrain as a range-extending solution intended to combine efficient electricity generation with the operational advantages of methanol-powered internal combustion technology for REEV applications.
