Inclusive Entry Design for the Volkswagen ID. Buzz

Mobility challenges affect millions worldwide, severely limiting independence and access to reliable transportation for individuals with disabilities. Despite advancements in assistive technology, existing vehicle entry systems—such as ramps and hydraulic lifts—continue to fall short due to high costs, mechanical complexity, and difficulties in achieving seamless factory integration. These limitations hinder widespread adoption and risk compromising user safety and independence. Our project targets the Volkswagen ID Buzz, an electric vehicle that represents a unique opportunity for incorporating inclusive design solutions directly into the production process. Our work is focused on enhancing vehicle accessibility for mobility-impaired users through innovative engineering that is both practical and compliant with stringent standards such as the Americans with Disabilities Act (ADA). We aim to overcome the limitations of traditional ramp and lift systems by developing an integrated entry mechanism that wheelchair users can independently operate. Our solution features a scissor lift mechanism seamlessly integrated into a modified car and door frame with linear actuators to fold the platform into the door, ensuring it remains stowed when not in use and fully extends to the ground when needed, optimizing both functionality and design. We developed a 50% scale prototype capable of withstanding 300 pounds, meeting ADA load-bearing requirements, and successfully demonstrated a full lift cycle while carrying a person. These results indicate that our design not only meets safety and accessibility standards but also offers a practical alternative for factory-integrated vehicle accessibility solutions.
