Tesla's upcoming Roadster to feature electronically controlled rear wing with collision safety protocols

Tesla's recently published patent describes an electronically deployable rear wing system destined for the next-generation Roadster. The component emerges from the car's body in fewer than three seconds and repositions its angle within 250 milliseconds. When engaged for maximum grip, the wing produces 700 kilograms of downforce in high-speed driving above 100 miles per hour, while an alternative setting eliminates downforce entirely to minimize drag. The design incorporates protective mechanisms including a mechanical latch that retracts the wing following forceful impacts and predictive systems that sense approaching rear collisions through camera, radar and lidar detection to trigger early retraction.

1. Patent continuation filed August 2025, building on original application from March 2025; the US Patent and Trademark Office released the filing publicly on September 24, 2026
2. Wing transitions between fully stowed and fully deployed positions in under three seconds; angle modifications occur within a quarter-second
3. Drag reduction setting produces zero downforce; maximum downforce setting generates 700 kg at speeds exceeding 100 mph
4. Integrated controller draws data from vehicle speed, steering input, brake application, GPS location, and autonomous systems to govern wing operation
5. Impact-triggered mechanical latch folds the wing away after collision; forward-looking sensors monitor for imminent rear-end impacts and command retraction
6. Tesla plans to reveal the Roadster on October 1, 2026, with speculation about potential SpaceX cold thrust integration
