Donut Lab Transforms EV Design with Unique Motors
At CES 2025, Donut Lab introduced an innovative solution poised to redefine the electric vehicle (EV) industry. Their cutting-edge second-generation motors, shaped like donuts, promise to significantly lighten vehicle weight while enhancing efficiency and power.
Traditionally, EV designs borrow heavily from combustion engines, featuring motors placed within the vehicle body and connected via complex drivetrains. Donut Lab challenges this norm by embedding the motors directly into the wheel arches, unlocking additional interior space for cargo or extra batteries. These motors boast a hollow center design, which explains the “donut” nickname and contributes to their reduced weight.
The 21-inch motor units deliver an impressive 630 kilowatts (845 horsepower) and 4,300 newton-meters (3,171 pound-feet) of torque, all while weighing merely 88 pounds (40 kilograms). This innovative design can eliminate the need for traditional drivetrain components, potentially reducing overall vehicle weight by hundreds of pounds.
While the lighter motors promise increased range and lower manufacturing costs—estimated to be up to 50% less due to fewer parts—questions about unsprung weight’s impact on ride quality and handling remain. Nonetheless, Donut Lab is hopeful that the advantages will outweigh any drawbacks.
Beyond cars, these adaptable motors are being developed for semi-trucks, scooters, motorcycles, and even drones, illustrating their versatility. This groundbreaking design may also encourage bold new vehicle aesthetics, emphasizing aerodynamics and creativity. Donut Lab’s technology promises to alter the landscape of EV engineering, making the future of electric transportation an exciting prospect to consider.
Revolutionizing Electric Vehicles: Donut Lab’s Groundbreaking Motor Technology
At the forefront of electric vehicle (EV) technology, Donut Lab has made waves with its revolutionary second-generation motors unveiled at CES 2025. These uniquely shaped motors, reminiscent of donuts, are set to not only transform the weight and efficiency of EVs but also challenge traditional automotive design paradigms.
