New EV Mashup Marries In-Wheel Motors With Modular Platform

The article highlights a new collaboration between UK automaker WATT Electric Vehicle Company and Finnish firm Donut Lab, showcased at CES 2026. Donut Lab specializes in advanced in-wheel electric motors, which integrate directly into the wheels, eliminating traditional drivetrain components like gearboxes and differentials. This innovation reduces unsprung weight, simplifies vehicle design, and enables higher torque and power density compared to conventional motors. Their flagship Donut Motor fits inside a 21-inch wheel, producing up to 630 kW (845 hp) and 4,300 Nm (3,171 lb-ft) of torque, while weighing about 40 pounds—significantly lighter than typical electric motors. WATT’s partnership with Donut Lab combines the latter’s in-wheel motor technology with WATT’s lightweight, modular “module-to-chassis” battery platform, creating a prototype skateboard EV platform currently featuring two rear in-wheel motors. This modular design promises enhanced agility and performance, with plans to launch a four-motor
