Amorphous Motor Debut Delivers 98.2% Hybrid Efficiency
Horse Powertrain, a global leader in innovative, low-emission powertrain systems, has introduced its groundbreaking Amorphous Motor technology to the world. This advanced hybrid transmission motor delivers an industry-leading 98.2% efficiency and enables a 1% reduction in whole-vehicle fuel consumption.
Horse Powertrain first showcased the Amorphous Motor at the IAA Summit 2025. The motor uses amorphous steel, a steel alloy that offers exceptional durability, strength, and magnetic permeability.
Horse Powertrain uses these properties of amorphous steel to reduce the thickness of the steel layers that form the motor stator. The company has reduced the sheets used to assemble the Amorphous Motor to just 0.025 mm thick. This thickness equals one-tenth of the steel used in traditional electric motor designs.
The highly conductive amorphous steel also reduces stator iron losses by 50% compared with equivalent motor designs. This improvement allows the Amorphous Motor to reach its industry-leading efficiency of 98.2%. The motor also delivers a maximum output of 140 kW and 360 Nm of torque.
These efficiency gains help hybrid powertrains achieve lower fuel and power consumption. Hybrids that use the Amorphous Motor can reduce consumption by 1% compared with vehicles that rely on existing electric motor designs. This improvement helps automotive OEMs develop a new generation of low-emission vehicles.
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 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 decarbonisation.”
Horse Powertrain supports ongoing innovation across the hybrid and combustion component stack through a global network of 17 manufacturing plants, five research and development centres, and 19,000 employees. The launch of the Amorphous Motor follows several recent announcements of high-efficiency technologies. These innovations form part of Horse Powertrain’s global strategy, which focuses on a technologically neutral approach to decarbonisation.
