Read original articleTesla has filed a US patent for an innovative inflatable aerodynamic deflector designed to improve the towing efficiency of its Cybertruck. The system consists of air bladders made from drop-stitch fabric that inflate from the truck bed to form a semi-rigid, wedge-shaped spoiler. This deflector bridges the gap between the Cybertruck and a trailer, smoothing airflow and reducing drag—a major challenge for electric pickups when towing. The device can be securely attached using various fasteners and includes a pressure-regulating mechanism to maintain stability. When not in use, it remains deflated and stowed, preserving the Cybertruck’s distinctive angular design.
Towing significantly reduces the driving range of electric vehicles due to increased aerodynamic drag, making solutions like this deflector critical for improving real-world performance. Tesla’s inflatable spoiler aims to channel air more efficiently over and around trailers, thereby conserving battery power and mitigating the range penalty associated with towing. Unlike permanent aerodynamic add-ons, this lightweight, deployable system offers flexibility and practicality.
