The Aria features a modular design, which includes detachable battery modules weighing twelve kilograms each. This allows for easy replacement of faulty parts without requiring specialized tools or technical expertise. The 13-kWh battery pack comprises six such modules, making it accessible to anyone familiar with basic automotive maintenance techniques.

One of the standout features of Aria is its bodywork design, which facilitates quick access to internal components by detaching outer panels. This approach contrasts sharply with modern EVs where batteries are often integrated into the chassis, complicating repairs and increasing costs for independent garages. The students aim to demonstrate that sustainable design can be practical and user-friendly.

Team leader Taco Olme emphasized the importance of repairability in electric vehicles, noting that current models often lack standardised parts and require proprietary tools for maintenance. He welcomed European legislation from 2024 that grants consumers the right to repair products more easily but pointed out that EVs are currently excluded from these regulations.

The Aria project underscores a broader trend towards sustainable design in automotive engineering, drawing comparisons to earlier models like the Volkswagen Beetle or Ford Model T, which were celebrated for their simplicity and ease of maintenance. The modular nature of Aria reflects this ethos, offering an accessible solution to the growing issue of EV repairability.

With its innovative approach to sustainability and user-friendly design, the Aria aims to inspire both policymakers and automotive manufacturers to rethink current practices. By showcasing what is possible within a year’s timeframe, the TU Eindhoven team hopes to encourage industry-wide adoption of more sustainable and practical vehicle designs that prioritize repairability.
