Tesla's latest idea to combat range degradation involves hot air, and it's serious.

A new aerodynamic development from Tesla

Tesla continues to surprise with its unconventional solutions, and this time it is a patent for an inflatable spoiler designed for the Cybertruck pickup truck. This device, called an “inflatable aerodynamic deflector,” can significantly improve the efficiency of the car when towing.

How an inflatable spoiler works

Using drop-stitch technology, similar to that used in inflatable surfboards, the device takes up minimal space in the back of the Cybertruck when folded. When towing, it inflates to form a wedge-shaped structure that extends the line of the cab and windshield, extending several feet and ending in front of the tailgate.

Officially called an “inflatable aerodynamic deflector,” the device uses the same drop-stitch fabric you’d find on a paddleboard or life jacket.



Benefits for Towing

The main goal of this invention is to reduce aerodynamic drag by smoothing the airflow over the cab and trailer. This will increase the range while towing, which is critical for electric vehicles, especially given their weight and limited charging station network.

Based on diagrams in a patent application first spotted by Carbuzz, the inflatable structure essentially extends the body line formed by the front hood and windshield of the pickup truck.





Tesla’s development context

Tesla has long been trying to solve the problem of reduced range when towing. The company previously announced an additional battery to increase range, which was planned to be placed in the bed, but this project was canceled, despite previous customer orders.

It’s worth noting that towing range is something Tesla has been working on for a long time. It has been shamed by promising a huge battery to increase range, which would be placed in the body.



Implementation prospects

The inflatable spoiler could be a small but important step in improving the efficiency of the Cybertruck. Unlike the canceled battery, this development has the potential for mass production, making it a practical solution for owners of electric pickup trucks.

The application of aerodynamic improvements is becoming increasingly relevant for electric vehicles, where every kilometer of range counts. Technologies like the inflatable spoiler could become standard for future models, especially those designed for commercial or recreational use. The success of this development will depend on its durability, ease of use, and real-world impact on energy efficiency in operating conditions.
