This 856 Horsepower Electric Motor Weighs Only 88 Pounds

Donut Lab, a British electric vehicle technology brand that is driven by a vision to push the boundaries of electric vehicle (EV) performance, is redefining the future of mobility with a new electric motor has a better power-to-weight ratio than Koenigsegg’s Dark Matter motor.

“Our flagship innovation, the Donut Motor, is the world’s first-ever in-wheel motor that combines maximum torque and power density with a lightweight design, eliminating the need for traditional drivetrain components. This breakthrough technology forms the cornerstone of a platform that consists of best-in-class components, each designed to excel independently and dominate when combined.”

Weighing in at just 88 pounds, the Donut Motor is fully integrated into the wheel and packs 856 horsepower. That’s the same weight as Koenigsegg’s Dark Matter motor, but with 56 more horsepower. While Koenigsegg’s motor offers 922 pound-feet of torque, according to Donut Labs, the Donut Motor can make as much as 3,172 pound-feet of torque, a whole lot of twist for on-road driving which would likely be tuned down for street-legal vehicles.

Also designed with motorcycle, truck, and even aviation use in mind, smaller, lighter versions of Donut Labs’ motor can be integrated into the wheel while still making plenty of power for high-performance vehicles. After all, 856 horsepower per wheel would be a bit much for most drivers to handle.

Speaking of, smaller versions of the Donut Motor are already used in Verge motorcycles.

“Great unsprung mass has been the most important reason why everyone hasn’t used motors integrated with the tire in their vehicles. Through the torque and power density we’ve now achieved, the relative weight of the motor is so small that for the first time the unsprung mass is insignificant,” said Donut Lab CEO Marko Lehtimäki.

Donut Labs states that its new motor is up to 50% less expensive to produce when compared to conventional electric motors. The lower cost and eyewatering performance of the Donut Motor could lay the groundwork for the auto manufacturers that are striving to produce more affordable EVs for the masses.
