Tesla’s Latest Solution To Range Loss Is Full Of Hot Air And That’s Not A Joke

- Tesla filed a patent for an inflatable spoiler designed for the Cybertruck.
- The add-on inflates into a wedge to reduce drag and improve aerodynamics.
- This range extension during towing could help make up for other failed tech.
If there’s one automaker in America willing to think completely outside of the box, it’s Tesla. In this case, it’s literally thinking outside of the box, or more precisely, from the bed of the Cybertruck.
A new patent application indicates that the company could soon sell an inflatable balloon that acts as a spoiler of sorts. If it works as intended, it could extend towing range by a significant amount.
A Wedge in the Wind
Officially dubbed an “Inflatable Aerodynamic Deflector,” the device uses the same drop-stitch fabric that you’ll find on a paddleboard or life vest. When stowed, it’ll lie flat in the bed of the Cybertruck.
When it’s time to tow, the owner can deploy the contraption, which will take the shape of a wedge. And when we say wedge, we mean a really big one.

Based on diagrams in the patent application first discovered by Carbuzz, the inflatable will basically extend the body line made by the front hood and windshield section of the truck. It’ll continue on that same plane several feet and end just before the tailgate.

Inflate To Tow Further
In essence, the device should smooth the air out over the truck and then over any trailer that may be in tow. Why make it inflatable? Elementary, dear Watson: weight savings.
Every ounce added to a vehicle has a small penalty in performance. That’s true in all vehicles, no matter their method of propulsion, but since it’s harder to find a charger and slower to charge an EV, it’s more important to keep weight down as much as possible in something like the (already pretty heavy) Cybertruck.

It’s worth noting that towing range is something that Tesla has been trying to sort out for a while. It infamously promised a huge range-extending battery that would’ve sat in the bed.
Despite several customers placing an order, the brand canceled the project and hasn’t really had a backup way to improve range during towing.
This new inflatable could be one small way to claw back some additional range. Now all Tesla has to do is, unlike that range-extending battery, actually put it into production rather than letting it float away like its last big idea.
