Rivian CEO explains why spectacular Tank Flip mode is a no-go


The fantastic Tank Flip function that Rivian confirmed off means again in December 2019 bought numerous truck and off-road lovers speaking, for good motive. 

The mode confirmed off the potential of utilizing all 4 of the electrical motors in Quad Motor R1T and R1S electrical vehicles to rotate the car round and round in basically the identical area, given a floor that was the correct quantity of slippery. 

It was a jaw-dropping transfer that Rivian managed to program in—making use of propulsion to the wheels in reverse instructions on the left and proper sides of the car, in a really managed method, that will be subsequent to not possible to engineer into a standard roadgoing gasoline SUV.

In an Instagram Q&A session posted Friday, Rivian CEO RJ Scaringe nonetheless sounded excited in regards to the concept, explaining how with the instantaneous torque (in both route) of electrical motors plus an array of subtle controls and a suggestions loop, “you’ll be able to create a torque second the place the car rotates on its heart axis like a tank.”

However Scaringe defined (under) why the Tank Flip function will seemingly by no means make it right into a manufacturing truck. 

Electrical vehicles have to tread flippantly, too

No, Scaringe didn’t point out attorneys or regulators placing the kibosh on it. 

The reason being easy, if the scar that the truck left within the video isn’t sufficient to underscore the purpose already. The Tank Flip has the potential to be actually damaging. 

Scaringe stated that over the past yr and a half, Rivian determined that whereas it may implement the Tank Flip, it’s simply not according to the corporate’s messaging to tread flippantly

“It is so simply abused and so laborious to make it possible for we do not tear up trails and actually do issues which might be in distinction to what we stand for as an organization,” he summed, noting that it didn’t really feel congruent with how Rivian preaches respecting the paths and never leaving ruts or injury. 

This seemingly means that one other patented Rivian parlor trick, Ok-Flip Mode, can also be a no-go. However the off-road prowess of the structure itself stays the promoting level. And as almost everybody who’s gone off-roading in an EV will agree, the acute finesse and precision at which electrical propulsion methods can ship torque makes off-roading much more pleasurable and fewer nerve-wracking. Rivian does already reap the benefits of this with distinct drive modes for the R1T and R1S.

Though it’s unclear whether or not Rivian might need dibs on the thought, Mercedes has already additionally teased the thought for its upcoming EQG electrical SUV, calling it a G-Flip.

Rivian is within the strategy of beginning deliveries of its Twin Motor vehicles, which function the corporate’s personal, cost-saving Enduro drive unit, together with motor and discount gear. They’ll finally be utilized to Quad Motor variations, too.
