Ultra-Compact Design for Flexible EV Platforms
HORSE C15 is a compact range extender technology offering within Horse Powertrain’s X-Range family, a category of solutions designed to enrich EV platforms with combustion and hybrid technology. No larger than a briefcase, HORSE C15 integrates an engine, generator, and inverter into a unit compact enough to be fitted within existing battery electric vehicle (BEV) platforms with little to no modification. This allows OEMs to easily and efficiently convert a BEV platform into a range extended EV (REEV).
Efficient Power and Flexibility
Featuring a 1.5-liter, four-cylinder engine and an integrated generator, inverter, and cooling package, the HORSE C15 measures just 500 x 550 x 275mm in its naturally aspirated version. HORSE C15 can be installed horizontally or vertically, unlocking exceptional flexibility in vehicle design.
Matias Giannini, CEO of Horse Powertrain, said: “Range extended EVs are the fastest-growing powertrain category in many global markets. The HORSE C15 range extender solution offers OEMs a straightforward and cost-effective way to tap this opportunity, and adapt their native BEV platforms into REEVs. HORSE C15 will play a critical role in this transition as one of the market’s most efficient and flexible REEV solutions to date.”
Compliance and Performance
Designed for Euro 7 compliance (including China 7 and SULEV20), HORSE C15 will be available in naturally aspirated form for B- and C-segment vehicles, with maximum engine power up to 70kW. For larger D-segment vehicles and LCVs, a turbocharger increases power output up to 120kW. The unit runs on both gasoline and synthetic fuels, maintaining the high-voltage battery charge which powers the vehicle’s electric drive motor.
Smooth Driving and Reduced Emissions
Unlike traditional plug-in hybrid vehicles (PHEV) and Hybrid Electric Vehicles (HEV), the REEV combustion engine never directly drives the wheels. This ensures minimal fuel consumption, reduced emissions, and smooth, responsive driving. When used with low-carbon fuels, the cradle-to-grave footprint is comparable to a BEV.
Horse Powertrain will be debuting the HORSE C15 range extender technology at IAA Mobility 2025, as part of its stand in Hall A2, Booth B40.
