Horse Powertrain has revealed a new hybrid transmission Amorphous Motor that has achieved an industry-leading efficiency of 98.2%, enabling a 1% reduction in whole-vehicle fuel consumption.
First seen at IAA Summit 2025, the Amorphous Motor uses amorphous steel – a steel alloy with high durability, strength and magnetic permeability – for the stator block.
By leveraging these properties of amorphous steel, Horse Powertrain has reduced the thickness of the steel layers required to make up the motor stator. As a result, the sheets used to assemble the Amorphous Motor are 0.025mm thick – one tenth the thickness of steel used in traditional motors.
Using this highly conductive material, the Amorphous Motor’s losses to stator iron are reduced by 50% compared to equivalent designs. This enables the motor to achieve efficiency of 98.2% while outputting a maximum power of 140kW at 360Nm.
These efficiency gains mean that hybrids using the Amorphous Motor in their powertrains will see a 1% reduction in fuel and power consumption compared to those using existing motor designs, helping automotive OEMs deliver a new generation of low-emission vehicle models.
Ingo Scholten, deputy chief technology officer of Horse Powertrain, said, “This latest innovation demonstrates Horse Powertrain’s continued commitment to research and development, providing suppliers and OEMs with the tools to raise the bar on when it comes to fuel economy and emissions performance.
“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 decarbonization journey.”
