I've never once seen or felt traction limited by them during hard launches.
You won't see or feel it, but if you have a quad, it is happening. There's no way they would not break loose with that power. When I limit or turn off traction control, they do squeal. Simple physics; no damn way can 835 HP get to the ground without traction control.

Here's my timeslip from April 15, 2023 for my 2022 R1T Quad Motor with large pack and 20" AT Pirelli Scorpion tires. I was in Sport mode with firm suspension and lowest ride height if I recall. I removed most items from the truck before taking it to the track. I was probably at 90% charge for this run. This was my best run, but the other runs were similar. This aligns with other instrumented tests I've seen from 2022.

Made some more runs today. It wasn't as high of an SoC and made some change to launching. This time it was just smash and go with traction control OFF. Posted later is just a fun run in conserve mode at 48% SOC from 50-70 mph.

I had a bunch of these runs tightly grouped. This one I actually had to let off at the end and then got back on it as I had to avoid an obstacle. So while the run was technically invalid, based on my other runs, it if was totally level, and I didn't have to left a little, and no crosswind or headwind, I think I could have been in the high 3.3's. Keep in mind this was on a 51% SoC.

The main difference for this run was taking off traction control. I also got the stab the go pedal technique down better. Brake torquing has consistently netted me slower times so far. I think the brakes might be grabbing to much. WIth rollout this would have been a 3.2 second run which is quite respectable given the conditions and drivetrain temps (incl battery). I had 5 runs back to back that were within .03 seconds of each other. I am to the point I am deleting runs that don't matter.

Conserve mode (50-70): For reference, C&D in Sport mode was about 1.17 seconds quicker than what I ran in Conserve. All in all, not bad TBH.

Good sir, that's not...how power works.

This isn't a debate. Power is defined as an equation of Force x (times) Distance / (divided by) time. It's physics.

Time is a constituent requirement of power.

You cannot have any power at all when time = 0. It's simply a mathematical impossibility.

You're not 'dumping' all of your power instantaneously. Horsepower is going to be rated within a graph, and its peak will be contingent upon a lot of factors.

Which is where I postulated the curve is going to be defined (tuned) by Rivian, and is highly likely (I'd bet quite a lot on it) tuned with respect to the characteristics of the truck within its configuration. In this case, it'll be tuned to maintain static friction (grip) of the wheels and tires.

You can retort something about torque, which is work (force x distance), but time is still the thing they can tune in/out of it. It'll also have limitations with respect to the motors and drives that Rivian uses. It'd be meaningless if you have 1,000,000 ft-lbs of torque, but it was measured at 1 inch per year, for example. How quickly can you impart the ~908 lbs-ft of torque is going to become your power number.


Edit: to your point, however, I have not tried turning down any of the traction options, and I've never done a 'full send' attempt at maximizing my 0-60, so you could verily be correct insofar as there is another level of traction limit (tuned acceleration curve) when fully enabled. And this may be the delta in our experience. Keep in mind that surface preparation, tire pressure, and environmental factors will also be contributing factors when taking in the full picture.

Thanks. Yes, I did charge for several hours this morning before starting out on a 48 amp charger. It got them up from the 30's into the 60's.

I am not chasing Rivian Hall of Fame times here. I am just trying to quantify how fast it is, typically under the conditions I'll drive it. It is also to provide a reference for others and to see how what works for them as well. So all the suggestion are good, and incrementally can make a difference. My past experience has show with my Teslas that for the street, almost none of it makes enough of a difference to be worth the hassle. If Rivian does offer a launch mode, I'd definitely try it.

At the track, it might be depending on who I was running. I think I only had one race at the track with my Plaid, where the difference of going through the hassle of getting it into cheetah stance and having my SoC over 95% would have made the difference between winning and losing. It can run upper 9.3's low 9.4's all day long without a bunch of hassle. On the street, I am usually between 50-60% SoC. That is where I usually keep all my EVs.

I'll only charge higher just before I leave so that my average SoC is right in the sweet spot of 50-55% for non-LFP batteries like in my Plaid and Rivian. That has really minimized the degradation on my Teslas and it should on the Rivian as well. On the Plaid it is even more critical as the battery doesn't have a lot of surplus power to feed what the motors can pull. Once it starts to degrade it will slow and there is nothing you can do about it. My Plaid and M3 LR are coming up on 3 years old and both have about 2% degradation. Obviously something I am doing is working. It should work with the Rivian.

Getting the temps into the 80's should get you a good deal more power. Still a reasonable temperature for a battery to be at during at least some portion of the year.

Thanks for sharing. Are you the left lane? What is your truck config?

Thanks, love the pic. Do you recall your SoC? That was a close race other than R/T.

The launch characteristic of the truck is significantly different between traction control on and even the mid way, reduced setting. Traction fully on is very soft off the line compared to traction reduced or off. If you have it off, and stab the accelerator, it feels like being rear ended by another car.

You crushed the other person while on AT tires with double their reaction time. Probably ruined their ego, ha.

You bought a Rivian for the race track/drag strip?

Are you going to start modifying it to get faster times? Special tires, special shocks, add some aerodynamic parts?

Or are you just seeing how fast they all go?

I bought an R1T for everything that it can do - from hauling to towing to camping to commuting to off roading. I am not planning on modifying it to get any faster - I took it to the track to see what it could do (and I feel that the track times are more accurate than Dragy times).. It also makes me feel good that it's operating well if it matches the instrumented times that the reviewers/magazines get.
