Convert EV to a hybrid: Horse Powertrain retrofit kit

Stagnating growth in demand for battery electric vehicles in some markets has prompted UK-based Horse Powertrain to develop a modular hybrid system that retrofit an internal combustion engine to existing BEV platforms with minimal modifications.

The company, a joint venture between Renault Group and Geely with backing from Saudi oil giant Aramco, revealed its Future Hybrid Concept (FHC) at the 2025 Shanghai Auto Show as a plug-and-play solution for car-makers seeking powertrain flexibility.

The innovative unit combines an internal combustion engine, electric motor, transmission and power electronics, allowing manufacturers to convert existing BEVs into hybrids without major redevelopment or new production lines.
