LONDON: Horse Powertrain has made the global debut of its groundbreaking “Amorphous Motor” technology.
This dedicated hybrid transmission motor achieves industry-leading efficiency of 98.2%, enabling a 1% reduction in whole-vehicle fuel consumption.
First showcased at IAA Summit 2025, the Amorphous Motor uses amorphous steel – a steel alloy with incredibly high durability, strength, and magnetic permeability.
By leveraging these properties of amorphous steel, Horse Powertrain has been able to dramatically reduce the thickness of the steel layers required that make up a motor stator.
As a result, the sheets used to assemble the Amorphous Motor are just 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 allows the motor to achieve industry-leading efficiency of 98.2%.
This is achieved while outputting a maximum power of 140kW (190PS) 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 automakers deliver a new generation of low-emission vehicle models.
Horse Powertrain deputy chief technology officer Ingo Scholten said, “The Amorphous Motor is an ideal tool to power a new generation of high-efficiency range extended EVs (electric vehicles), hybrids, and plug-in hybrids.”
Horse Powertrain’s continued innovation is powered by a global footprint of 17 manufacturing plants, five research and development (R&D) centres, and 19,000 employees.
Horse Powertrain is a new global leader in hybrid and combustion powertrain solutions, supporting automakers with a range of systems including engines, transmissions, power electronics, and integrated hybrid platforms.
Consisting of two divisions, Aurobay Technologies and Horse Technologies, Horse Powertrain counts some of the world’s leading automakers among its 20 customers.
Horse Powertrain is headquartered in London, UK.
The company’s three shareholders are Renault Group (45%), Geely (45%), and Aramco (10%).
