The automotive industry is on the brink of a revolution with the introduction of donut-shaped engines that are expected to transform electric vehicles (EVs). These motors, developed by Donut Lab, are designed to be directly fitted onto wheels, reducing weight, increasing power, and lowering operational costs. The second-generation motor displayed at CES 2025 boasts 630 kW of power and 4,300 Nm of torque at a mere 40 kg weight, making it an attractive option for EV manufacturers. The benefits of donut-shaped engines are plentiful. They lead to increased efficiency in battery systems, longer battery range, reduced vehicle weight, and lower manufacturing costs, potentially making EVs more accessible and appealing to a wider market. However, challenges like unsprung weight, which can affect braking and cornering, need to be mitigated through innovative engineering solutions. Despite these challenges, the versatility of donut-shaped engines extends beyond cars to motorcycles, delivery vehicles, and drones. The scalability and affordability of these motors hint at a future where they become a standard in the transportation industry. While there are still hurdles to overcome, the promise of environmentally efficient and high-performance transport through these innovative engines is a hopeful sign of what's to come.
