Rivian includes rollout, that might be where the discrepancy is occurring. I do agree though, German cars always sandbag their times and efficiency numbers so you know it will do what it says or better. Better has been my experience as well.
What tires do you have on your R1T? You will get better performance with street tires. Also did you launch with your foot on the brake at full throttle? Seems like 3.1 or even 3.3 is pretty close to the best time you could possibly get. Seems pretty nitpicky to me.
Yes, that's correct. AP is not responsive at all by EV standards, even if you drive around with stability reduced to keep the rear motor active.
I have the 21's (street tires).
So they nerfed the Gen2 large pack's size and, possibly nerfed higher speed acceleration of the PDM. Sounds like something Tesla would do.
The 21s are the range tires, not the sport tires. For the best 0-60 you'll need the 22s.
The motors on the G1 QM are actually all identical. The difference is that the front motors are geared slightly taller and the rear shorter, though the Munro video didn't give numbers that I remember. But this is one reason the axle disconnects are on the rear motors...taller gearing is better for highway speeds for efficiency. The rear is shorter since weight transfers to the rear under acceleration and RJ stated that the front was still traction-limited even with the taller gearing, so it wouldn't be surprising if they were pulling some power from the front to maintain grip. The G2 Tri and Quad will have more powerful motors at the rear vs G1 to take full advantage of the extra grip at the back end. I will say that on a slick (ice/snow) surface drift mode is highly entertaining. I had the opportunity to run a snowcross last winter and only discovered this on my final run, but the truck was so much easier to control and really point where you wanted it. It wasn't a big deal that you're effectively down on power since you can't put much down on the snow anyway, but it dialed most of the understeer out of the truck while trying to pirouette around tight corners.
This matters 100%, @DayTripping. You'll get best performance on a Gen1 Quad with the 22s. The Gen2 Quad comes with a new Michelin Pilot Sport 5 as the spicy tire and in a staggered setup with 305s out back, IIRC. Just putting winter tires on my R1T QM from the factory Pirelli 34" ATs I notice a huge drop in acceleration performance, though I haven't instrumented it yet. They definitely changed the programming a bit since last winter as now if I peg the throttle off the line it'll actually spin the tires where last winter it would not, and this is in AP mode. I almost feel like the .47 update did give a little more pep to AP mode, but I could be dreaming...again, no instrumentation. Even the 34" tire diameter will make a difference for outright performance over the 33s...the 33s will effectively be shorter gearing and faster acceleration, but less top speed, as well as weighing less than the 34s.
The Dragy showed up but I couldn't find any places to do full passes or even launch. I was able to get in some 30-70 runs in AP. For comparison, here are the numbers Car and Driver got for a 2022 LE QM.
Here are the numbers I got 2024.47.01 in AP mode. SoC was 68%. I have a 2023 R1T Adventure Edition QM on 21's. It was 55F, and my battery temps were 65F when I made my first pull and motor temps were all under 80F. Between me and the cargo in the truck, probably looking at 500#'s as I had a bunch of tools in the gear tunnel and I am 230#. All times are with a Dragy. There can be some slight rounding occuring.
AP runs
First pass:
30-50: 1.21
50-70: 1.96
30-70: 3.18
30-80: 4.45
Second pass:
30-50: 1.08
50-70: 1.87
30-70: 2.94
30-80: 4.22
Sport runs
My first pass was:
30-50: 1.22
50-70: 1.86
30-70: 3.08
30-80: ran out of room
They were ran in order. So the Sport run had the advantage of the warmest pack and motors but they weren't hot. At the end of the last run they were at about 122-125. Which is pretty close to the temps I see running down the highway in AP or Sport mode. The second AP run was even slightly uphill, enough that it was considered an invalid run but being uphill made it all the more impressive than the Sport mode which was pretty level.
You can draw your own conclusions from the numbers but the one clear thing is everyone one of my passes bested the C&D numbers. Combining their 30-50 + 50-70 times puts it at about 3.8 seconds. At worst I was 7 tenths better and at almost 9 tenths. This is significantly better. Even more impressive is was at a 68% SoC when I started.
What is interesting, but not surprising, is the AP best run was better than the Sport run, even with the drivetrain not up to temps yet. The power meter is definitely showing higher on the AP runs than Sport as others have noted.
For a reference point, the R1T will hang pretty well with a refreshed (2021+) Model S long range until until about 65 mph. That car is very quick from about 50 mph up. Mine would run 10.8's in the 1/4 all day long and trap in the high 120's.
I'll do more runs when I have time. I plan to do most of the runs around 60-80% SoC. If I charge to 90-100%, I won't drive it enough to run down the charge quick enough. I hate to keep it at a high SoC to minimize degradation.
Not sure if there is enough interest, but a dedicated Dragy thread (if there is one I couldn't find it) could be interesting to other acceleration junkies like me.
I started a thread here:
Good information, but I do have a question. I have a Gen 1 Quad and I've never seen the display screen you show. Where is it and how do I get there?Has anyone noticed the yellow bar will not max out at highways speeds at full throttle in sport?
Try it in all purpose and while the response is slow you will see the bar max out. (Assuming sufficient charge temps, and traction)
but this is not enough for me I love performance and data. I used the service screen to confirm that in sport while at low speeds you will get 1600amp briefly above 40mph the amps max out at 1400amps, in all purpose over 40 you will get 1600amps. With a full charge the voltage will sag to about 385v if you do the maths 385x1600 =616kw or about 825hp this seems on point. But why why why do we only get 700hp when in sport over 40?
I was even more shocked when this was backed up by repeated 50-100 runs using a “draggy” measuring device.
Average 50-100
Sport 6.25
All purpose 5.52
That is 14% slower in sport!
I ran this experiment on multiple days slightly varying all possible variables like ride hight traction control ect and yet the results are consistent within a few %
I would love to see if anyone else can confirm this. The good news is that the yellow bar is a true representation of the amps. Or power however you want to think of it. Just imagine 835hp or 1600amps at the top (gen1 quad)
I would also love to see if this is the case on some of the other motor setups especially if someone is willing to get in the service screens and see what amps the gen2s are pulling.
First photo is sport , second is all purpose 3rd is draggy comparison of 50-100 times.
