Couple of my takeaways from this document that I didn't anticipate learning.

Test results: https://www.rivianforums.com/forum/attachments/foi_srivt00-01l2_appipt1_041024-pdf.96359/

-R1 still uses CCS ports.
-21" Wheels seem like they may have been eliminated starting in 2025, most efficient option became a 22" aero wheel.
-2025 models will have heat pumps.
-AC compressor was relocated to improve NVH.
-DC and AC charging rates appear unchanged for the LFP vehicles.
-Still only 15A 120V outlets off the AC inverter.
-LFP standard range appears to match the existing rating for software locked non-LFP standard range batteries, but is appreciably more efficient considering battery size went from 105.9 kWh to 92.5 kWh
-Battery weight went from 796 kg to 727 kg, Volume from 562L to 505L.
-GVWR unchanged, R1 Vehicle weight without battery weight difference is inconclusive since optional equipment is not mentioned in either 2024 or 2025 documents.
-Peregrine program named confirmed by the EPA document.


More notes by @zefram47
  • 20" tire size only listed as 275/60/20 instead of the 275/65/20
  • Heat pump specifically mentions waste heat recovery
  • Adds a dedicated HV battery heater (instead of only using the motors for heat?)
  • Interestingly, AC charging called out as 220-240V. Surprised it doesn't say 208V is allowed and a shame 277V isn't specifically supported.
  • Fascinating...curb weight listed as 6532 lbs R1S and 6507 lbs R1T continuing with 8532 lbs GVWR
  • Claimed range (not real-world / adjusted range...need to compare with current R1 EPA test data to be meaningful):
    • R1 20": 380 miles city / 322 miles highway
    • R1 22": 405 miles city / 340 miles highway
    • Both reported numbers show an R1S test vehicle, so R1T may be slightly higher

What would we do without @Dark-Fx ? The efficiency of the LFP batteries is very interesting indeed. The 21" wheel option is very curious, and frankly disappointing given that you have to get the whole offroad upgrade to get the 20" wheels. Thank goodness there are good aftermarket solutions out there.

Interesting, thanks for posting! Wonder what the price point for LFP standard range will be?

I expect it to be a little bit less than it is currently, but it's hard to say. It looks like they probably still have similar suspension. In the photos in the documents, I don't see a standard sway bar and am fairly sure the hydraulic lines are still present. Some had been speculating they might drop the air suspension for a less costly coil-over setup, but it would add significant complexity to their production so I didn't expect it, personally.

I have an expectation that a lot of the vehicles coming off the line first are going to be bottom of the barrel cost wise, because of the current economic environment and difficulty Rivian is having selling the higher cost trims.

Surprised that CCS1 port is still used instead of NACS. The updated vehicle must be 2025 model year and they dont have NACS worked out for in-vehicle install at this time.

The most interesting is the elimination of 21" wheel. Pirelli made special tire for Rivian. Now not being used. Must have finished the contractual obligation.

Of course this means 275/55/21 tire size is orphaned and without a real alternatives since going forward it will not be equipped by Rivian. No other tire maker will make this size for such a small user-base.

Luckily I have the 22" so maybe theres's a hope for more tire options.

Thankfully, as expected.

-AC compressor was relocated to improve NVH.
-LFP standard range appears to match the existing rating for software locked non-LFP standard range batteries, but is appreciably more efficient considering battery size went from 105.9 kWh to 92.5 kWh
-Battery weight went from 796 kg to 727 kg, Volume from 562L to 505L.
Very welcome and great to hear. Still holding out hope that they've modified it somewhat because it's both loud and inefficient.

-DC and AC charging rates appear unchanged for the LFP vehicles.
I'm still on team 800v, but it will be an upsell for more $$$ trims.

I'm not surprised. Next-Gen RAN stations are still going to be CCS with NACS support via adapter. They mention native NACS support "with a future hardware update", so it'll probably be a while.

The LFP pack is really interesting, especially if it reduces the cost somewhat, but it's definitely still limited by the inability to upgrade to DM-P.

For sure I am hoping the same thing. At least since it appears the overall efficiency has gone up that the range should go up on identical large/max pack vehicles. Looking like Max could end up being ~450 mile range rated.

And if they are going to keep the currently poor Max Pack pricing structure, offering 800v charging capabilities, among a few other features, could help better justify the cost difference.

If the vehicles are that much more efficient I could see range estimates staying the same, especially for the lower trims. This would help improve build cost while offering a competitive product.

Hopefully they also offer the 20” wheel with a AS tire and not the whole AT package.
21 wheel discontinue is not that curious to me at least as there is lots of info on this forum and just general physics that smaller wheels aka 20’s on AS 275/60/20 tires are more efficient than the 21’s. Which is curious is why they would make the 22’s a aero wheel.

Agree, the 275/55/21 tire size is a real "head scratcher" as Rivian essentially configured a unique tire size. Still only the OEM offering from Pirelli, and nothing else available on the market.

Probably because if 20" was offered as the baseline, people would not upgrade to 20" AT very often. People will take delivery with baseline wheel and aftermarket to 20"AT at a significant less cost than the factory option.

I hope Rivian will switch to a single lithium battery for low-voltage uses.
Maybe a situation where the different battery chemistry is preferred depending on things like temps.
