Why Gen 1 did not receive "tank turn" - answers from Rivian

[electric-offroad]

My jerk of a neighbor is VERY appreciative that I don’t have tank turn.
But seriously, having a feature like that leads to nothing good. And inevitability, folks would be doing this on dry pavement, causing what I can only imagine would be serious damage to the vehicle. Another case of, just because you can, doesn’t mean you should.

it only really works on a level loose surface, and will tear that surface up along with the tires. In a tank turn all the wheels loose traction, so if there's any slop the vehicle will tend to slide downhill.

Looks cool, but not very practical.

Add me to the I still want launch mode for my Gen 1. It has to be doing more than just lowering the truck. I timed Gen2 Trimax runs with and without it and it is faster in launch mode than just sport. My truck in sport is as quick, as a Tri in sport. So something else is going on.

I think it was MBKHD or whatever his channel is that listed that his test G2 quad was slower than his Gen 1 quad when both are sport.

I'd take advantage of the raised the speed limiter.

From TheDrive: https://www.thedrive.com/news/heres...turn-on-the-first-generation-r1t-and-r1s-quad

TLDR:

• Bosch motors are water cooled.
• Rivian's in-house motors are oil cooled.
• "Ultimately, Rivian’s Chief Software Officer Wassym Bensaid told The Drive that 'we don’t have the same level of control on gen-one Quad' to activate the feature. Left unsaid is the fact that they also seem more confident in their bespoke motors to handle the stress, since Kick Turn can be activated at forward speeds up to 15 mph."

It’s bullshit. They could limit how fast a Gen 1 can do a tank turn, to prevent any damage to the vehicle.

Not only this but They had this working on demo cars of the G1, most people seem to forget this. I remember it even on the demo drives they gave. 100% related to making the G2 Quad special for 2x the price....These are the things I don't like about Rivian. Very snake like.

The way I see it, I don't want the additional complexity. Plus, you can see in forums that most people don't even know how to use audio EQ. And, they got our money already. The development cost required of gen 1, if they were to offer it as part of a OTA update, doesn't seem like how one would operate a [profitable] business. And then there's the aforementioned technical limitation: lack of control over the Bosch motors. Plus, if gen 1 owners had a path to all these upgrades, there'd be no motivation to upgrade to newer. No up-sell.

Fine. BUT there were so many things promised to us and then cancelled or walked back. And that’s what folks are pissed about, myself included.

Keep shouting into the wind and see where that gets you. It’s worked so well so far. /s

Bullshit. Tank turn was a concept feature on a concept car - Rivian canceled that feature well before they took their first order and well before any vehicles were delivered to any customers. No one bought a Rivian expecting to get tank turn. Or if you did, you were just deluding yourself.

It was cool, but problematic from the beginning (read this forum if you want to learn). The one overhead video that most people saw was clearly unstable, sliding around like a water drop on a hot griddle, and we have since learned Wassym had to be in the back seat controlling everything from a laptop, and even then everyone was surprised when they were able to make one mostly-successful take of the video.

The Bosch motors don't have the same capabilities as the Enduro motors. That's a fact, whether you think it would be "easy" to implement this on a Gen 1 or not. Regardless, the feature itself was fatally flawed and needed to be re-worked into what is now the kick turn. And it took them more than 4 years to develop the kick turn into something that can be shipped to customers. Everything points to it's a lot harder to do than it looks, and depends heavily on the motors and suspension, rather than Rivian is deliberately withholding features from early adopters.

Bullshit? I don’t care about rank turn but
Referring to the actual things promised and then undelivered. Should’ve clarified if that was confusing.

Referring to the actual things promised and then undelivered

First, this thread is about tank turn. Read the title, read the previous posts. I don't know what you're specifically talking about if it's not tank turn, but I'm not inclined to argue about all those other fake claims because there are dozens of threads devoted to each. The closest I can think of to "promised and then undelivered" is the camp kitchen, but technically they never took an order for those either, even though they cancelled it well after shipments to customers started. All the other complaints amount to entitled whining IMNSHO.

It was working on demo drives? I don't recall any demo drive showing off tank turn.

A friend of mine was the driver during the infamous tank turn demo video Rivian released, and Wassym was crouched in the back seat with a laptop forcing motor controls manually from his laptop. It was never working from the vehicle's own controls. I know neither mine nor my brother-in-law's early test drives months before our vehicles shipped in 2022 had tank turn as an option. (And my brother-in-law took his to a muddy field and did some donuts - if tank turn had been available, he absolutely would have used it.)

It would be cool to get some kind of trail turn for Gen 1, like on the Bronco where it just drags the inside rear wheel. Kick turn seems kind of like a gimmick for rally driving and too wild to actually use on a narrow trail

GM just updated the Hummer with a new 4 wheel steering mode, called king crab. The rear steering gain becomes 2x the front gain. They already had gain changes in different modes, but the highest gain was 1.2x previously.

I swore I read years ago that Rivian cancelled tank turn for environmental reasons. AI can't be wrong:

Tank Turn cancelled

 

[iansriv]

I'm happy with my G1 R1 as is. I'm used to buying cars as they are and am thrilled for the extras with the OTA changes. I cant recall any document, at the time of purchase, where Rivian promised me Tank Turn. If Rivian had, I would be just as miffed as most on here; despite not seeing any practical use for TT.

 

[IGR]

Personally I don’t care about tank turn, and I don’t recall Rivian explicitly advertising this. However, I did see this feature in promotional videos, therefore it was implied to have it. Am I upset about not having it? Nope. But it’s not a good look for Rivian to tease something like that.
as one youtuber once said: never buy a product based on promises… and I strongly believe in that

Correct. The reason they gave was that it was harmful to nature. But once The G580 debut with tank turn all of a sudden it became available on the G2QM.
