Rivian confirms tank turn feature for electric R1T, R1S

Flush with cash from Amazon and Ford, among others, Rivian is moving full speed ahead. It confirmed the R1T and R1S due out in late 2020 will be available with a unique tank turn function.

The feature gives Rivian's battery-powered off-roaders the ability to perform a 180-degree turn by spinning in place like a tracked vehicle. We first heard of it in July 2019 when a video showing it in action surfaced on YouTube, but the company quickly pointed out it wasn't authorized and had it taken down. This time, it's official; Rivian announced the tank turn on its verified Twitter account.

Performing a tank turn requires simultaneously spinning the left and right wheels in opposite directions, which is why there's not one car sold new in 2019 that's capable of it. Rivian's models can pull it off because the drivetrain they're both powered by assigns each wheel its own electric motor. They're individually controlled, so getting the wheels on the driver's side to spin forward and the ones on the passenger's side to turn backwards requires little more than a few lines of code.
