A New Era in Electric Vehicle Innovation
At CES 2025, Donut Lab introduced groundbreaking technology that promises to reshape electric vehicle (EV) designs and their capabilities. Their innovative second-generation in-wheel motors, characterized by a unique “donut shape,” aim to significantly cut down vehicle weight while ensuring high power and efficiency, potentially ushering in a new phase for the EV market.
Traditionally, EVs have borrowed designs from gas-powered vehicles, placing motors within the car’s structure and connecting them to the wheels through a complex drivetrain. Donut Lab reimagines this concept by embedding motors right inside the wheel arches. This smart design allows for more room inside the vehicle, accommodating additional cargo, passengers, or battery power. Each 21-inch motor unit boasts impressive specifications, generating as much as 630 kilowatts (or 845 horsepower) and 4,300 newton-meters (3,171 pound-feet) of torque—all while weighing a mere 88 pounds (40 kilograms). The significant reduction in system weight may translate to enhanced performance and efficiency in EVs.
However, the increased unsprung weight in the wheels raises concerns regarding vehicle handling and ride comfort. Nonetheless, Donut Lab remains hopeful that the benefits, such as superior torque and simplified production processes, will ultimately outweigh any drawbacks.
This innovative motor technology isn’t limited to cars; it has adaptations for semi-trucks and electric scooters, indicating a broad market appeal. As Donut Lab’s designs push the boundaries of EV aesthetics and functionality, the future of electric transportation looks bright.
