Executive Summary
The electric vehicle industry is witnessing a transformative breakthrough as Finnish startup Donut Lab secures €25 million in seed funding to revolutionize EV propulsion systems. Their innovative 'Donut' in-wheel hub motor technology represents a fundamental shift in how electric vehicles are designed and powered. By integrating the motor directly into the wheel rim, Donut Lab eliminates the need for traditional drivetrain components, potentially reducing vehicle weight, improving efficiency, and lowering production costs. The company's expansion into the UK with a new R&D hub, coupled with the strategic addition of former Nokia chairman Risto Siilasmaa to their board, positions them to scale their technology across multiple vehicle categories. This development signals a potential turning point in EV architecture that could reshape the future of electric mobility.
Current Market Context
The electric vehicle market is experiencing unprecedented growth, with global EV sales expected to reach 14 million units in 2023. Traditional EV designs have relied on centralized motor systems, requiring complex transmission mechanisms and heavy drivetrain components.
