Horse Powertrain unveils high-efficiency hybrid motor

Horse Powertrain has unveiled a hybrid transmission motor using amorphous steel alloy that it says achieves 98.2% efficiency, enabling a 1% reduction in whole-vehicle fuel consumption compared to existing motor designs. The motor, first showcased at IAA Summit 2025, outputs peak power of 140kW at 360Nm and is designed for use in hybrids, plug-in hybrids, and range-extended electric vehicles (EVs).

Amorphous steel offers high durability, strength, and magnetic permeability, allowing Horse Powertrain to reduce the thickness of the steel layers in the motor stator to just 0.025mm—one tenth that of traditional motors. The company said this reduces stator iron energy losses by 50% compared to equivalent designs.

In a statement, Ingo Scholten, Deputy Chief Technology Officer of Horse Powertrain, said: “The Amorphous Motor is an ideal tool to power a new generation of high-efficiency range extended EVs, hybrids, and plug-in hybrids, ensuring these technologies continue to play a substantial role in automotive’s decarbonisation journey.”

Horse Powertrain operates 17 manufacturing plants and five research and development centres globally, employing 19,000 people. The company said the motor forms part of a broader strategy focused on a technologically neutral approach to decarbonisation.
