A team of innovative students from Eindhoven University of Technology (TU/e) in the Netherlands has unveiled a groundbreaking Modular Electric Car prototype named ARIA. Designed with sustainability and practicality in mind, ARIA is not just an eco-friendly vehicle—it’s a car you can repair yourself, challenging the current trend of complex, hard-to-fix electric vehicles.
The key innovation lies in ARIA’s modular construction. Unlike traditional EVs, where a single fault can mean replacing an expensive and integrated system, ARIA is built from separate, easily replaceable components. The body panels, interior electronics, and battery modules are all designed for independent replacement. If a part breaks, owners can simply swap the faulty component without needing a mechanic.
Detachable, lightweight batteries are a standout feature. ARIA uses six battery packs, each weighing approximately 12 kilograms (26 lbs), which can be removed by hand, much like changing batteries in a household device. Together, these six modules provide a total capacity of 12.96 kWh. This design not only simplifies maintenance but also prolongs the car’s lifespan by making battery replacements affordable and accessible.
The car is DIY-friendly, equipped with a built-in toolbox, detailed repair manuals, and a companion app that diagnoses issues and provides step-by-step guidance. Even exterior repairs are straightforward—scratched or dented panels can be removed and replaced in minutes, instantly revealing the components behind them. The modular design, developed through collaboration between students from TU Eindhoven, Fontys, and Summa, showcases practical, hands-on innovation in automotive design.
TU/ecomotive’s vision goes beyond convenience. Modern EVs are increasingly difficult to repair due to integrated batteries, non-standardized parts, and a shortage of specialized technicians. This often leads to vehicles being discarded prematurely, undermining the environmental benefits of electric mobility. ARIA addresses this by promoting longevity, sustainability, and user empowerment.
The project also aligns with European Right to Repair legislation, which currently focuses on electronics and household appliances. “EVs still fall through the cracks,” explains team manager Taco Olmer. By creating a car that consumers can maintain themselves, TU/ecomotive demonstrates the feasibility of applying these principles to passenger vehicles, inspiring both policymakers and the automotive industry.
By supporting the Right to Repair Europe coalition, TU/ecomotive advocates for fair access to spare parts, software updates, and repair knowledge. ARIA embodies the movement’s mission: giving control back to the user while fostering a more sustainable, repairable future for electric vehicles.
