Amidst the dynamic landscape of electric vehicles, one company is poised to make waves with an innovative approach. The UK-based Watt Electric Vehicle Company is partnering with Finnish firm Donut Lab to showcase a cutting-edge integration of modular EV platforms and in-wheel motor technology at CES 2026 in Las Vegas.
Revolutionizing EVs with In-Wheel Motor Technology
While in-wheel motors are not new to the world of conventional internal combustion engine vehicles, their application in electric vehicles (EVs) marks a significant advancement. According to CleanTechnica, “The holy grail of electric vehicle technology is in-wheel electric motors, which put power directly to the street and eliminate a host of other parts.” Research by SAE International suggests that EVs equipped with in-wheel motors demonstrate an 18% efficiency improvement over their single-motor counterparts.
Donut Lab, a pioneer in in-wheel motor technology, first attracted attention at CES 2025. Their new motor, fitting within a 21-inch wheel, boasts impressive specifications. Each motor is capable of generating up to 630 kilowatts (845 horsepower) and 4,300 newton-meters (3,171 pound-feet) of torque. Weighing in at approximately 40 pounds (88 kilos), the motor is significantly lighter than traditional electric motors. Donut Motor, as it’s called, combines maximum torque and power density with a lightweight design, eliminating the need for conventional drivetrain components.
Diverse Applications Across Vehicle Categories
In September, Donut Lab revealed a comprehensive lineup of five electric motors at CES 2025, designed for a variety of vehicle categories. From scooters and motorcycles to heavy-duty trucks and drones, each motor incorporates direct-drive architecture, ultra-high torque, and a lightweight footprint.
The Donut Motor stands out by eliminating gearboxes, driveshafts, and differentials, thereby reducing unsprung weight and simplifying vehicle design. The motor’s unique shape, featuring a larger diameter and minimal active materials, allows for higher torque and power density, offering more power per kilogram than conventional motors. This innovation not only enhances performance but also reduces drivetrain costs and enables the development of flat-floor, modular vehicle platforms.
Innovative Partnership with WATT Electric Vehicle Company
Donut Lab’s collaboration with WATT Electric Vehicle Company is set to unveil a prototype at CES 2026. This partnership combines WATT’s “module-to-chassis” integrated battery platform with Donut Lab’s agile in-wheel motors. Although the current prototype features only two motors for the rear wheels, a four-motor version is anticipated later in 2026.
WATT emphasizes the platform’s versatility, capable of supporting various vehicle configurations from beach buggies to high-performance sports cars and commercial delivery vehicles. The modular approach of the platform significantly lowers the barrier to entry for new vehicle development, maintaining high standards of performance and efficiency.
At the core of this partnership is the precision control of each Donut Lab in-wheel motor, enabling advanced torque vectoring and enhancing driving dynamics. The elimination of traditional powertrains reduces weight and complexity, while improving energy transfer efficiency. The system’s real-time control capabilities offer superior accuracy, stability, and traction control, transforming the driving experience.
EV Prospects in the US
While the US market faces challenges in EV adoption, California remains a beacon of hope. The state, which would rank as the world’s 4th largest economy if independent, shows strong commitment from EV stakeholders. Moke International plans to introduce the Moke Californian open-air electric car in the state, and the IONNA EV charging joint venture is set to invest over $250 million to expand its network of “Rechargery” stations. The initiative also includes outreach programs aimed at first-time EV buyers.
IONNA’s recent announcement highlights that Rivian and Ford vehicles, along with those from founding members BMW, General Motors, Hyundai, Kia, and Mercedes, can now utilize the Rechargery “Plug & Charge” system. By the end of 2026, Honda, Stellantis, and Toyota vehicles are expected to join. This investment signals optimism for the future of EV sales, particularly in California.
