Yasa, the British axial-flux electric motor specialist owned by Mercedes-Benz AG, has produced its 50,000th electric motor, marking a new milestone for the company as it scales up manufacturing to meet rising demand from high-performance electric and hybrid vehicles. The milestone unit rolled off the production line at Yasa’s facility in Yarnton, near Oxford.
The production achievement follows the opening of Yasa’s fully modernised electric motor plant in May, which provides annual capacity of more than 25,000 units. The company has also posted a series of technical performance benchmarks this year. In July, Yasa reported a record for power density in electric motors, which it surpassed again in October when a motor weighing 12.7 kilograms briefly delivered peak output of 750 kilowatts on a test bench.

The company reflected on its development in a statement shared on LinkedIn, saying, “From our first product in 2010 to powering some of the world’s most advanced performance applications, including Ferrari SF90 Stradale, Lamborghini hybrids and the next generation of Mercedes-AMG electric cars, every motor represents our pioneering spirit and engineering precision.”
Yasa Chief Technology Officer Tim Woolmer said the company’s production growth had accelerated sharply with the commissioning of the new plant. He noted that Yasa built just 20 motors in 2010, while in 2025 alone it is expected to manufacture around 20,000 units. “Going from 20 motors per year in 2010 to 20,000 motors per year in 2025 represents a 60% year-on-year growth every year for 15 years. Should be at 20m per annum by 2040,” Woolmer wrote in a comment.

Yasa specialises in compact axial-flux electric motors, which differ from conventional radial-flux designs by aligning the magnetic field along the axis of rotation rather than the radius. This configuration allows higher power density and a smaller overall motor size, often resulting in a distinctive disc-like form factor.
Mercedes-Benz AG acquired Yasa in 2021 and has since integrated the technology into its high-performance electric strategy. In 2023, the automaker unveiled the Vision One-Eleven concept car featuring Yasa’s motors. That development culminated in the AMG GT XX, which uses three axial-flux motors and set multiple performance records in August, supported by the high output and efficiency of its powertrain.
