New Tesla Roadster with system to stay glued to the road
Tesla continues to patent quite intriguing solutions, and the latest one involves a suction system designed to stick cars to the asphalt.
For now, these are just rumors, but everything suggests that the second generation of the Tesla Roadster, which will be unveiled in a few weeks, will feature such a system to keep it stuck to the asphalt.
Do you remember the McMurtry Spéirling, the 1000 horsepower electric hypercar that uses massive fans on its body to generate 2000 kg of downforce? The logic is exactly the same, but instead of being limited to a model for racetracks only, it could be applied to a road vehicle.
The American brand recently filed a patent with the United States Patent and Trademark Office (USPTO), under the code US 2026/12746987 B1, following another patent that described a massive active rear wing capable of generating up to 700 kg of downforce, which we have discussed before:
How does it work?
The patent describes an “electric fan car” equipped with four electric fans mounted on the rear diffuser, “configured to increase downforce and reduce drag.”
According to the document, this system can “include a diffuser that extends from an inlet at the lower part of the vehicle’s body to an outlet in the rear section,” as shown in the image below.
In other words, the idea behind this solution is not to add propulsion but rather to smooth airflow and the turbulence it creates beneath the car, as well as to “suck” it against the asphalt. Examining the patent drawings, this solution appears to affect only the rear end of the vehicle.

Is it for the Tesla Roadster?
Like the huge spoiler we reported a few days ago, it’s not clear which model this solution is intended for, though it wouldn’t be surprising if we saw it implemented in the Roadster.
But while the patent for the active rear wing showed a concept car with a coupe design, the solution the brand has just patented is integrated into the design of what appears to be a Tesla Model S. Interestingly, that model has already stopped production.
Moreover, although both patents were registered within a short period of time, nothing ensures they are for the same model or that they will even make it to production. It could simply be a coincidence, as brands constantly file patents.
On the other hand, if we consider the performance promises made by Elon Musk for the Roadster — 0 to 100 km/h in less than two seconds and a top speed exceeding 400 km/h — it wouldn’t be entirely unreasonable for this solution to feature in the Roadster, whose unveiling has been delayed until next day 15.
