Horse Powertrain's Future Hybrid System can hybridize EVs

Horse Powertrain revealed more information about its all-in-one hybrid powertrain, the Future Hybrid System, at IAA Mobility 2025 in Munich in September. The new details involve a 1.5-L, four-cylinder unit with integrated engine, motor, and transmission that was designed to replace an EV's front electric drive module to convert that EV into a hybrid, PHEV, or range-extended EV.

Horse Powertrain revealed two variants of the Future Hybrid System (FHS) in Munich. The first, called Performance, is 740 mm (29 in) wide and uses two motors in a P1 + P3 configuration, with one each on the engine output and transmission output shafts. The second, the Ultra-Compact, is 650 mm (26 in) wide and is designed to sit between the engine and transmission. The 1.5-L engine, a dedicated hybrid transmission, and a full suite of power electronics for hybrid use are used in both versions. The company said an even smaller version - by 70 mm (3 in) - with three cylinders is being investigated.
