Never mind Elon's Tesla Cybertruck, the Rivian R1T pickup and R1S SUV are still very much on Roadshow's most anticipated new trucks list -- EV or otherwise. And if both all-electric vehicles weren't at the top of our must-drive list before, they might just be after this video detailing a killer new feature: Tank Turn. 

We've heard rumblings about this tech for some time now, but the electric-truck startup has now confirmed that its four-motor setup will allow for what could be the best vehicular donuts this side of a Monster Jam monster truck. With four motors that can be independently powered in different directions simultaneously, opposite-phase drive is possible. Translation? You can have one side of the vehicle's wheels powered in one direction, while the other side's wheels go in the opposite direction, resulting in the ability to pivot within the vehicle's wheelbase: just like the tracks on a tank. Such a feat would be very difficult and likely very costly to engineer on a conventional internal-combustion-powered truck with differentials. 

As you can see from this video, you'll probably need to execute such maneuvers on dirt or gravel to avoid excessive driveline stress, but this new Rivian feature could be more than just a killer party trick -- Tank Turn figures to be a boon on tight trails where you're hemmed in by trees and rocks. Rivian has stated that off-road ability is a priority for its electric trucks from Day One, and this could be a unique way to make good on that promise.

It's not clear how this feature is activated -- it seems unlikely that you summon Tank Turn just by cranking the steering wheel all the way in one direction. It's also not clear whether Tank Turn will be standard or optional. We likely won't know more until the Rivian R1T pickup and R1T SUV hit the market, which is expected to be in late 2020 or early 2021.

The R1S's Tank Turn feature will make it one unique SUV.

In any case, Rivian appears to be headed into 2020 with a full head of steam. On Monday, it was revealed that the Plymouth, Michigan-based startup has raised a further $1.3 billion in funding, with repeat investors Amazon and Ford among them. Ford, you may recall, has already signed a $500 million deal with Rivian to employ the company's "skateboard" architecture to underpin a future electric Lincoln, and Amazon previously invested $700 million in the company in furtherance of a purpose-built all-electric delivery van, the latter of which is expected in 2021.

Will you see Amazon Prime vans hurriedly executing the world's coolest donuts at Christmastime in 2021? Probably not. Then again, if you live on a gravel or dirt road...
