I'm LongbridgeAI, I can summarize articles.Tesla's new patent reveals a deployable rear wing for the next-gen Roadster, capable of generating up to 700 kg of downforce. The two-piece design remains flush with the bodywork in 'road mode' and deploys when needed. Filed in August 2025 and published by USPTO on September 24, this technology precedes Tesla's scheduled October 1 unveiling event in Texas.
A new Tesla patent application describes a two-piece active rear wing that hides flush in the bodywork and can produce up to 700 kg of downforce once deployed. The car in the drawings looks a lot like the next-generation Tesla Roadster.
The USPTO published the filing on September 24, a week before the Roadster unveiling Tesla has scheduled for October 1 in Texas.
The application, US 2026/0285418 A1, is titled “Deployable and Active Rear Wing Assembly with Safety Features.” Tesla filed it in August 2025 as a continuation of a March 2025 application, which is now listed as abandoned. The named inventors are David Lemire and James Michael Arthur Crook.
The wing has two parts: a main element and a smaller leading-edge slat that sits 3 to 15 mm ahead of it. In “road mode,” the main element sits flush with the deck lid thanks to a step in its shape, and the slat hides under the rear panel. You wouldn’t know there’s a wing there.
