Donut Lab And WATT Electric Vehicles Develop Lightweight, In-Wheel Motor EV Platform

in-wheel motor platform

Summary: Donut Lab and WATT Electric Vehicle Company have partnered to integrate Donut Lab’s in-wheel motor technology into WATT’s ultra-lightweight PACES skateboard platform. The combined system eliminates conventional powertrains, using rear in-wheel motors (with 4WD to follow) to deliver high performance, agility and modularity across multiple vehicle types. A functional prototype is planned for display at CES 2026.

Engineering takeaway: Combining a module-to-chassis battery platform with direct-drive in-wheel motors enables precise, millisecond-level torque control at each wheel. Removing drivetrains, differentials and axles reduces mass, inertia and mechanical losses while freeing packaging space. Software-defined torque vectoring becomes a core vehicle attribute rather than an add-on system.

Why it matters: This architecture lowers the technical and cost barriers for new and niche EV manufacturers to deliver high-performance vehicles. It shows how lightweight structures and in-wheel propulsion can fundamentally reshape EV handling, efficiency and platform flexibility. The approach points toward simpler, more modular EV architectures with greater software control over driving dynamics.


Donut Lab and  WATT Electric Vehicle Company (WATT) today announce an innovative partnership that promises to set new standards in electric vehicles. It combines the class-leading light weight enabled by WATT’s ‘module-to-chassis’ integrated  battery platform with the agility of Donut Lab’s in-wheel motors . The two companies will show a functional prototype skateboard platform at CES 2026 in Las Vegas on the Donut Lab stand.

The collaboration centres on WATT’s PACES (Passenger And Commercial  EV Skateboard), an innovative low-volume aluminium platform technology renowned for its class-leading lightweight construction. PACES will now incorporate Donut Lab’s in-wheel motor technology, featuring two direct-drive motors at the rear axle, with a four-wheel drive variation coming later in 2026. 

The result is an exceptionally lightweight EV platform that delivers huge performance and unrivalled agility, capable of spawning multiple vehicle configurations from beach buggies to high-performance sports cars to commercial delivery vehicles. This modular approach dramatically lowers the barrier to entry for new vehicle development while maintaining the highest standards of performance and efficiency.

At the heart of this partnership’s innovation is the ability to independently control each Donut Lab in-wheel motor with millisecond precision. This creates unprecedented degree of torque vectoring during cornering on tarmac or when finding grip off-road. 

By eliminating traditional powertrains entirely, the direct-drive architecture removes unnecessary weight, frees up package space and reduces complexity while dramatically improving energy transfer efficiency. The system’s real-time control capabilities provide levels of accuracy, stability, and traction control far beyond what conventional systems can achieve, fundamentally transforming the driving experience. With next-gen software-defined driving dynamics the OEM is in full control of the desired drive experience for the end-product.

“The integration of Donut Lab’s revolutionary in-wheel motor technology represents a significant leap for what PACES can offer the automotive world,” said Neil Yates, CEO of WATT Electric Vehicles. “Its motors, inverter, and software systems, perfectly complement our lightweight platform philosophy. The direct, fine control of the individual wheel speeds brings an agility and that is perfectly complemented by the low mass and inertia of our chassis technology. This skateboard can produce vehicles that will set new benchmarks for EV handling.” 

“WATT EV’s PACES platform provides the perfect canvas to showcase the full potential of our advanced motor technology,” said Marko Lehtimäki, CEO of Donut Lab. “The exceptional low mass of PACES allows our high-torque, high-power-density in-wheel motors to truly shine, delivering a driving experience that would be impossible with heavier platforms. When you combine our direct-drive precision control with WATT’s lightweight engineering expertise, you create something genuinely transformative, a vehicle architecture that’s lighter, more efficient, more powerful, and infinitely more engaging to drive.”

The WATT-Donut Lab skateboard platform’s modular nature opens doors to an extensive range of vehicle types and applications across multiple segments. The simplified architecture also reduces manufacturing complexity, minimises lifetime maintenance requirements, and lowers overall costs compared to traditional electric powertrains, making high-performance electric vehicles more accessible to smaller manufacturers and niche markets.
