Horse Powertrain has unveiled a small, modular hybrid engine system designed to fit directly into the space normally occupied by a front electric motor — potentially allowing manufacturers to convert pure-electric models into hybrids from 2027. Lightweight hybrid conversions could offer lower running costs, extended range and broader fuel flexibility on future EV-derived models.
The firm’s Future Hybrid Powertrain comes in two versions: a 740mm-wide Performance unit with two electric motors, and a 650mm Ultra-Compact version with one motor positioned between the engine and transmission. A three-cylinder option that trims a further 70mm is also under development.
Both use a 1.5-litre four-cylinder engine, hybrid transmission and integrated power electronics, supporting 800V charging and the ability to run as a full hybrid, plug-in hybrid or range extender. They can power the front wheels alone or be paired with a rear motor for all-wheel drive.
Horse says the design can cut front overhang by up to 150mm and mounts to the same subframe as an EV motor, helping manufacturers reuse existing BEV components. The units can run on petrol, E85, M100 methanol or synthetic fuels. Space freed up by smaller hybrid batteries could also accommodate a fuel tank without major platform changes.
