Rivian 'Tank Turn' is exactly what it sounds like

Trick feature spins the electric truck in place, but only on dirt

Update: Predictably, the unauthorized video has been removed from YouTube. The rest of the article continues below.

Video has surfaced of a Rivian R1T doing a "tank turn" — that is, spinning in place like a tracked vehicle. It's clearly CGI, and Rivian let us know it wasn't published by them. So maybe it's from the electric carmaker's ad or marketing agencies, or maybe just a talented fan. All that said, the EV startup has itself talked up such a feature. TechCrunch ran a piece last December saying, "Rivian trademarked terms 'tank turn' and 'tank steer' referring to independently moving wheels that can enable extremely tight turns. [Rivian CEO R.J.] Scaringe confirmed that this feature would be available on the R1S, the R1T, and future quad-drive vehicles."

According to the U.S. Patent and Trademark Office, Rivian filed to trademark Tank Turn and Tank Steer on Oct. 24, 2018, but both applications are dead. That feature, however, remains possible, since the R1T and R1S utilize four independent motors at the wheels; there's no reason they can't rotate the vehicles — wheels spinning forward on one side and in reverse on the other, as in the video, to do a smart about-face when confronted with a washed-out road.

And since Rivian filed for the vehicle names R1A, R1C, R2A, R2C, R2R, and R2S, there are likely a few more off-road-capable offerings that could make use of the trick — especially that rumored Rivian rally car.

We imagine there'll be a few restrictions imposed in the fine print, such as not pulling the maneuver on paved roads or other high-grip surfaces. A commenter on another article wrote, "Brian Gase from Rivian confirmed to me that this feature will be on dirt/gravel only. In his words, if you do this on pavement you will 'break shit,'" Gase being Rivian's chief engineer. Of course, the Audi RS3 converted to electric power with four Formula E motors and 1,183 horsepower spun quite the burnout-in-place before burning rubber out of frame, and didn't seem to have a problem, so anything is possible. We're eager to see what Rivian's come up with.
