Rivian Automotive will not enable the "tank turn" feature in its R1 off-road vehicles because the four-wheel thrust needed to rotate in a circle is potentially damaging to trails, CEO RJ Scaringe confirmed in response to a question on social media.
The feature was the subject of a viral video posted on Christmas Day 2019 that showed a silver R1T pickup spinning in a circle, clockwise, in a muddy field. The promotional spot was made before the electric truck went into production in 2021. The video attracted 2.3 million views on YouTube.
"This was something early in the program that we planned to do," Scaringe said on an Instagram video last week as he answered questions from fans of the California EV brand. "In fact, we showed a video of it."
Tank turn is made possible by the inclusion of four motors on the top-end R1T, one at each wheel, Scaringe said. When left-side motors are pushing forward and right-side motors are pulling backward, the pickup can spin on its center axis. The quad-motor configuration puts out 835 hp, Rivian said.
But as the video shows, the trick is rough on the dirt surface beneath the spinning off-road tires.
