Usually does. FMVSS dictates that it can indicate lower than actual, so manufacturers add error to give a buffer.
Our R1S with 22" sports is 2mph optimistic. I'm aware of the law but I've also had vehicles that were spot on. I wish there was a way to calibrate the Rivian speedo.
Anybody have any idea of what batch has gone out yet? My launch edition is vin 006450 and I still have not gotten the update.Looks like 2025.06 is out to the public starting today.
I mean really thinking about it you shouldn’t even need to set the tire size. The vehicle has onboard GPS they should be able to take in the speed measured by GPS and take a measurement of axle rpm and calculate total wheel size, you could optionally add total tire/rim weight to further dial in the range estimates
We're only 58 hours into the update being released. It will take at least a week as Rivian sends it out in batches to not overwhelm the system. First priority is Connect+ subscribers, which is over 80% of Rivian owners. Some are expecting that they will be the first, but with that many subscribers, some will have to wait too. There is no specific order that they flag your vehicle for download. If it were by VIN, I would have been one of the first on day 1 every time since I'm VIN 000045. I didn't get flagged until 34 hours in this time. I have waited up to 10 days for some of the updates to be flagged for download. Be patient, it will come s00n.
Thanks for the response I appreciate you I will just wait patiently.
Yes, I’m in the high 6000s. Downloaded without issue a few hours ago. Mirror tilt seems to be working.
Hell ya! How many miles? What was your delivery date?
Original owner took delivery 12/2021. I bought it off of him (Rivian employee) in May, 2023 with 21K miles. Been all over the place, up to Mt. St. Helens, down to LA, out to Dallas for the eclipse and back through Monument Valley and Canyonlands adding another 34.5K miles in the last 22 months totaling 55.5K miles on it so far!
I've not done the testing myself, but I've heard that this is by design. The vehicle knows what speed you're ACTUALLY going, and odometer/trip meter readings are bang on. But the speedo on the dash purposefully displays +2 mph for liability sake, so people don't speed as much
Thanks for the report. This is why I tend to wait a few weeks before doing the update. I'm more than happy to be last and let the "I WANT THE UPDATE NOW!!!" gang do the beta testing ahead of me.
This is the norm for most cars. I did noticed that my 100% charged all purpose mode went from 303 miles down to 285 when switch to 20". 275/60/20". This is absolutely not true becaused I had 18K miles on it and it is slightly more efficient than my original 21". Each of them have been thru the whole season of winter/summer.
