Yasa sets world record: 550 kW electric motor with the highest performance density in the world

The British company Yasa Motors, a daughter of Mercedes Benz, has a new one in a prototype test unofficial world record set up: only one 13.1kg of heavy electric motor Should a performance of 550kW (748 hp) reach - this corresponds to a power density of About 42kW per kilogram. According to Yasa, the highest value so far became worldwide in any area of application achieved.

Revolution in electromotor development

The record was loud Tim Woolmer, CTO and founder of Yasa, more by chance found in internal tests. In a LinkedIn post, he speaks of a historical moment:

"We all love new world records. They are a yardstick for our progress and drive our innovations forward."

For comparison:

• Equipmake HPM-400 (2023): 400kW at 30kg → 13kW/kg

• Helix engine (2024): 650kW at 28kg → 23kW/kg

• Yasa prototype: 550kW at 13.1kg → 42kW/kg

The engine contains no exotic materials such as Cobalt iron slats or Strand wire, was not by 3D print Made and is still record -breaking. With this, Yasa wants to prove that such results are possible without elaborate special technologies.

Series production and scalability

Particularly noteworthy: the new engine is scalable and ready for series production. Yasa plans with an annual production of up to 50,000 units to economically portable costs. Series production could soon be in the Yasa plant in Oxfordshire (UK) start.

Yasa already delivers electric motors today Mercedes-AMG, Lamborghini and Ferrari. The power density now reached opens the door for completely new vehicle concepts - from super athletes to light electrical aircraft.

"This result shows what is possible when deep tech, research and practice work together," Woolmer told Autocar.

Meaning for electromobility

According to Yasa, the record is not only a milestone for its own company, but for the entire electric motor industry. Performance density is a central factor for efficiency, weight saving and new drive concepts.

Conclusion:

Yasa has one with its new 550 kW electric motor new scale in terms of performance density set. Without exotic materials, but with high engineering, the company impressively shows the potential in the next generation of electric motors.
