LONDON—YASA Ltd. has received the Royal Automobile Club’s prestigious Dewar Trophy for its axial-flux electric motor, which is smaller and lighter than traditional devices. It saves weight by using up to 80 percent less iron and significantly less copper than traditional e-motors.
The motor is scheduled to enter mass production in the next generation of Mercedes-Benz AMG cars in late 2025. YASA was acquired by Mercedes-Benz in 2021.
