Tesla has been very skillful at keeping the latest version of its Roadster under wraps. The prototype was unveiled almost ten years ago, and since then we’ve only seen a few highly restrained previews. Over the past decade, there have been many speculations and even more delays. Now, finally, it seems everything is ready for the major launch scheduled for October 15th. The official details have been carefully controlled, but a newly published patent might change that.
The official document filed with the United States Patent Office describes an active rear spoiler with several aerodynamic configurations. What’s interesting is the vehicle it’s illustrated on: a highly detailed sports car that closely resembles an evolved Roadster. Many have already announced that this will be the final appearance of the new Roadster, which bears some resemblance to the concept introduced almost a decade ago.
A spoiler with a load capacity of 0 to 700 kg
According to the patent, the system can generate zero aerodynamic drag in DRS mode and up to 700 kilograms in its most aggressive setting at top speed. The document mentions speeds exceeding 161 km/h (100 mph) when discussing high-drag operation. This is an extraordinary figure for a car wing used on road vehicles and indicates exceptional performance potential.
To put this in perspective, the McLaren Senna, approved for road use, generates 800 kg of drag at 250 km/h with the entire car. The Senna GTR, designed only for circuits, reaches 1,000 kg, and Aston Martin has cited over 1,000 kg for the Valkyrie AMR Pro. Tesla claims up to 700 kg just from the Roadster’s rear wing.
A low and wide coupe, not a copy of the 2017 prototype
The illustrations show a two-door, two-seater vehicle with a very low profile, prominent rear wheel arches, a fastback-style trunk, full-width rear lighting, and a sizable diffuser. Defined side surfaces as well as specific tire and window designs are also visible. Additionally, it appears to be a fixed-roof coupe rather than the 2+2 convertible roof model Tesla showcased in 2017.
Still, if it were a generic vehicle to illustrate the technology, someone at Tesla would have gone to great lengths to design it. With the Roadster once again accepting $50,000 reservations, any hint about its final appearance holds special value for future buyers. They will still have to wait. The Roadster’s unveiling was supposed to take place on October 1, but the event had to be postponed to October 15 due to weather conditions.
The big caveat: Tesla never says it’s the Roadster
The application, US 2026/0285418 A1, is titled “Deployable and Active Rear Spoiler Set with Safety Functions.” It protects the aerodynamic system rather than the appearance of the car surrounding it. Submitted in August 2025 as a continuation of another application from March 2025, it was published by the U.S. Patent and Trademark Office (USPTO) on September 24. Therefore, it cannot be claimed to be a production Roadster. It is possible that Tesla, like other manufacturers, has filed a patent it will not apply for in the short or medium term.
