Horse Powertrain has unveiled a groundbreaking ‘Amorphous Motor,’ a dedicated hybrid transmission unit that achieves a staggering 98.2% efficiency, setting a new benchmark for the industry.
First showcased at the IAA Summit 2025 and officially launching its global debut this week, the motor promises to reduce whole-vehicle fuel consumption by 1%.
While that may sound incremental, in the world of OEM emissions targets, it is a massive leap forward.
The Amorphous name refers to the stator’s construction. Traditional motors use stators made of stacked silicon steel laminations, usually around 0.25mm thick.
Horse has swapped this for amorphous steel, a glass-like alloy with no crystalline structure, offering incredibly high magnetic permeability.
Because the material is so conductive and strong, Horse has been able to shrink the stator layers to just 0.025mm thick. To put that in perspective: it is one-tenth the thickness of traditional motor steel. It is thinner than a human hair.
In a standard motor, energy is wasted as heat through “iron losses” (hysteresis and eddy currents) within the stator. By using ultra-thin amorphous sheets, Horse has slashed these losses by 50%.
The result is a motor that stays cooler and converts more battery energy into movement, outputting a peak power of 140kW (approx. 188hp) and 360Nm of torque.
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.”
