R1S Off-Roading with Family [Video]

tjaco007 · Nov 11, 2022

Took the R1S off-road with the family over the weekend. Pretty much sold me in keeping this thing as long as it will run!

Went with some friends who brought their side by side. Pretty awesome to get to our destination, do some crawling, and then head home all in the same vehicle. Drift mode was everything it's hyped up to be.

How do you find on road ride as that has been coming in for some criticism recently.

I think it's all relative. My previous car has been a M3P which is pretty rough from a ride perspective, so going to the R1S in All Purpose mode feels super comfortable. In fact, I generally drive it in Sport mode because it's lower to the ground and feels more similar to what I'm used to.

Definitely don't have criticism on the ride quality, but that's just me.

Great video and thank you for sharing - the baby in the frunk and the kids laughing made me giggle!

Yeah, I was fairly confident I wouldn't be re-selling the vehicle prior to taking the family out. But the laughs and enjoyment from them definitely sealed the deal.

(I also didn't deflate the tires at all, which would have helped with some of the slippage I got. But even at full psi it wasn't too bad.)

First off - jealous you have yours and I don't.
Secondly- keep having fun and showing the world how amazing yet practical of a vehicle it is.

However - question/thought. With 4 motors, why does the wheel continue to spin when it has no traction, shouldn't the computer realize this and reduce power there while increasing it to the other wheels which do have traction (ie not moving). I'm not a code writer but simple logic seems to be IF wheels rotating <4 then reduce power to wheels >=1 rotating and increase power to wheels >=1 not rotating. It goes back to that logic in my mind that unless you are highcentered and all 4 wheels are spinning, you should never be stuck.

Yeah I completely agree with your thought.

I definitely could have reduced tire spin by airing down the tires. But even that aside, I remember seeing the early marketing material on the Rivian, about how 4 motors means it puts the torque exactly where it's needed. But I didnt get the sense it was quite that sophisticated when taking it out.

Not at all criticizing Rivian. The vehicle is miles above the competition. Clearance and torque are incredible, and everyone else with their jeeps and trucks commented how electric is the future of off-roading. But I do think there's potential improvement via software updates on how the vehicles recognize which wheels really have traction.

Another video showing example of wheel spin that shouldn't happen. Although in this case it was doing better, but any wheel off the ground should not be spinning. Again logic = if pressure = 0, then spin = 0.... Do I need to be a coder or what :giggle:

Maybe it tests for traction by rotating at a slow speed? It may need to look for resistance in the wheel to determine if its in the air or on the ground. It does seem like something that could be done through the suspension also, but maybe its simpler to look for resistance through torque than to look for maxed out suspension in one of the wheels.

I got my ID.4 stuck in the snow last year, and it did something similar; it would slowly spin the wheel to see if it had traction, and then allow throttle inputs based on that; if it found no traction, no matter what I did it wouldn't provide power. If it happened to find traction (while rotating slowly), it let me spin the wheels. Made it really hard to get unstuck with no way to turn off traction control, because all it would do was measure for traction, and when it didn't find any it would turn off power to the wheels.
