Mercedes unveils record-breaking electric motor

Just a few months ago, Mercedes-Benz subsidiary YASA unveiled the most powerful electric motor in history. Engineers have refined their prototype, which is now capable of delivering more than 1,000 horsepower. Mercedes plans to use the development in its future cars.

The developed motor produces 59 kW per kilogram. That is 79 horsepower per 1 kg, which significantly exceeds Yasa's previous record (56 hp per kg). With a weight of only 12.7 kg, the prototype produces a peak power of 750 kW (1006 horsepower). For comparison, this is the level of hypercars with less weight than an average electric bicycle. Even in continuous load mode, the motor demonstrates performance at the level of 350-400 kW (469-604 horsepower).

Importantly, no rare or expensive materials are used in its production. Unlike traditional radial systems, the axial flow relies on thin disc rotors that deliver more torque with less weight.

YASA's technical director and founder, Tim Woolmer, called the result “the most important confirmation of the effectiveness of the new generation of axial electric motors.” Mercedes, which bought YASA in 2021, plans to put these motors in its future flagship electric sedans and SUVs.
