I noticed when he launched the R1S he didn’t do a brake stand like Rivian advises, I’m not sure if that makes a difference as I’ve always launched my truck by holding both pedals down and letting go of the brake. I’d be curious to know if that makes a difference in launch times

2/1/23–refreshed update preorder holders, “damnit Rivian, I’m out.”
2/2/23–Rivian beats Lambo and Super Snake, “I’m so excited to get my Rivian”.

yeah, hard to believe we have to bring up a "limiter" when discussing quarter mile times for a performance vehicle. I wonder if it's due to a cooling limitation.We’ve got to do something about that speed limiter so these Rivians leave no doubt

watching that all I can think is "man that Lambo's seat looks a lot more comfortable than my R1S seat"

2 of those are propelled by noise?
And remember folks, electricity travels faster than the speed of sound....

I'm thinking it's more like the 7000+ pounds of vehicle with 800+ HP. Not to say that the other two aren't wicked heavy and wicked powerful, they are. Most larger vehicles with squishy suspensions I've had have a limiter in the 100MPH range, including a couple Raptors. I suppose the R1S could tighten up the suspension and be really planted, but geez, that's a lot of vehicle to control at 100+MPH.
Seems like Lambo has no choice, a limiter wouldn't do well with their brand. Plus it's got MASSIVE brakes. And that Shelby...I couldn't paid enough to ride in that rig. I've seen a Shelby Raptor tear 6" of cargo bed sheet metal on both sides in Baja just due to really bad engineering.

I think the main (at least advertised) speed limiter is in the tires, especially for the 20" ATs on the Rivian and the off-road shoes on the Shelby. I also read somewhere on this forum (so it MUST be true) that the original "first drive" R1Ts for the press events were limited at 130 mph - wouldn't that be fun! The post went on to point out that the motors' limits were ~150 mph and it was determined that 130 mph would potentially put too much stress on the motors, hence the lower 110 mph limit.
Either way, I think 115-120 mph limit would be better to at least allow the truck/suv to continue accelerating all the way through the quarter-mile...sucks to be maxed out for last 100 or so ft of the contest.

Yep, that makes a lot of sense. The tires I'm sure are a huge limiter. Again, 7000lbs, 800+HP...yeah I want some stout, high speed rated tires! AT's probably are going to cut it! I wonder if the 20's, 21's, and 22's all have their own unique limiter MPH's? Or at least AT's vs the other two.
While I agree it would be fun, I think I'm OK with Rivian trying to keep me alive (says the 48 year old me, the inner child disagrees). I'm that nitwit that if it'll go 130, I have to see. When I first got a Model S Plaid in June '21, they were limited to 163MPH and I just had to see. That thing accelerated so hard to 163 that it felt like it hit a wall when it reached the limiter. A soft wall, but it was very noticeable. I'm thinking the R1's would feel the same at their limited MPH.

Yeah like others have said the limiter is probably due to tires and motor stresses. I still think they could juice it up enough to not top out in a standing quarter.

if it is then THAT should be the "limiter" and until that threshold is reached, let the power go. I believe there were early mentions of R1Ts crossing 130 so there's still top-end left and realistically if it's kicking in "a few car lengths" prior to 1/4 mile you're not gonna put significantly more heat into the entire system over the next 0.2s or so. It would be nice to let these vehicles "breathe" just a little bit more - even a 120 cap seems like it would be a meaningful difference and yet a pretty small increment to unlock.
