Tesla has filed a patent for an inflatable aerodynamic deflector designed for its Cybertruck, aiming to improve towing efficiency by reducing drag when pulling a trailer.
The Cybertruck, known for its stainless-steel exoskeleton and sharp-edged design, already offers a lower drag coefficient than most pickup trucks. However, towing remains a challenge as trailers generate significant aerodynamic drag.

The U.S. automaker said in its patent application: “An inflatable aerodynamic deflector to reduce drag and enhance efficiency. Constructed from drop stitch material, it forms one or more air chambers between parallel skins. The component includes a pressure regulation mechanism and diverse attachment interfaces such as rail systems, magnetic fasteners, and quick disconnect clips, distributed along the vehicle for secure mounting. This component acts as an aerodynamic deflector, optimizing airflow around conveyances, especially combination vehicles like tow vehicles and trailers.”

According to the filing, the inflatable device would be mounted on the Cybertruck’s bed, rising to reduce the air gap between the truck and a trailer. By extending the angle of the windshield over the trailer, the system is intended to redirect airflow and enhance towing range efficiency.
Tesla has not disclosed when or if the technology will be incorporated into production models.
