2025 R1S Tri-Max Delivery, Storm Blue, Ocean Coast

[Ddowns2050]

when I get it back later this week from PPF I will charge to 100% and report back. In my road trip last week, I charged to 85% and it showed 298 Miles.

In theory…

141 kw battery
85% = 119.85
298 / 119.85 = 2.486
2.486 x 141= 350 miles in All purpose

swflor, I agree with your calculations as mine have been about the same. When I do the math when I put 30% back in the battery and check what the truck says what the kw's put back in are, it prorates to 141 or actually a little better. I just don't understand why it doesn't display what Rivian says it should be.

If you look on Rivian's website it shows 371 and 405 miles respectively what the range should be. This is my 3rd Rivian and the only one that doesn't display the Rivian claimed range.

As far as charging your truck to 100% when you get it back. You don't necessarily need to do that. Just hit the lightning bolt in settings which takes you to your energy window. Under your display miles it will say for example 250 miles, and under that it will say miles in all purpose or whatever mode you are in. If you touch that box it will display a window showing how many miles you have at the current rate of your charge and what miles you will have at 100% in conserve, all purpose, and sport mode. It will show all 3 projections.

Makes sense.

This is my 5th Rivian. All the others are Quads.

Honestly, I’ve never paid much attention to the efficiency…I put tires on that give the best ride, when the battery needs charged, I charge it. I bought them because they are awesome machines….not because I wanted to go 500 miles on a charge. Hahaha.

I will look at the R1S Quad this morning and see what it says…you have me curious now.

2023 R1S Quad, sitting on 20s

this was delivered with Sport Dark 22” with Pirellis. I immediately switched them to Continental Terrain Contact AT 22”. I switched this to 20s and had it reprogrammed…

22 program with 20s, speedometer is low by 2mph
20 program with 22s, speedometer is high by 2mph

I would rather be going slower than I think vs faster.

Look was way better. Efficiency was similar to what I was getting on my 24 R1S with 20s.

the 20s ride better, so for every day I stick to 20s on the Quads and switch to 22s when I want a different look.

In the Tri-Max, I immediately put Michelin Defender LTX MS2 on the Dark 22s and so far enjoying that. Still not as cushy as the 20s, but the Michelins are way better than any other 22 tire I have tried.

Will get these same screen shots on the Tri-Max hopefully Thursday or Friday.

Sounds good. Let me know. I hope you meant tri max. But let me know on that if you get a chance. I'm curious also. I'm also very glad to know there is someone worst than me with 5 of these awesome vehicles. Ha!

the info I posted above was for a Quad. Shows 273 in All Purpose on 20s. I think original stated was 274.

my tri-max is getting PPF installed right now so once I get it back later this week I can report back on what the max miles is showing on the screen for full charge.

Rivian service is checking logs and is going to report back. I just want to make sure that this brand new battery doesn’t have diminished capacity or some bad cells or something out of the ordinary but when Rivian Service gets done I should know the whole scoop.

are they doing that remotely or did you have to take it to them.

They are doing it remotely. They asked me to charge to 100% and let them know when that is done so they will have a time stamp. They are then going to see if the truck is really charged to 100% or if the display is incorrectly showing that it is at 100%.

got it. Keep us posted.

That would be great, though normally I'm not super worried about being ultra nerdy re range and efficiency - i think something interesting is going on here - based on what I'm seeing in this thread I'm starting to wonder how much more efficient the tri motors are compared to the gen1 Bosch drivetrains. There's many factors that make this a hard comparison - and though the 21" wheel was just to weird to live, i do now wonder if the relative efficiencies of the drivetrains was a factor in its discontinuation - as it makes direct comparison a bit harder.

Using the 2023 Quad motor R1T (21" wheels) as an example, and comparing with the gen2 Tri with its stock 22" wheels (note lower rolling resistance tires on gen2 22" wheels compared to gen1):

Drive Mode (rivian defaults for height etc)	Gen1 Quad R1T Range Advertised	Gen1 Quad R1T Range scaled assuming 141kWh battery	Gen2 Tri R1T Range Advertised	% diff based on drivetrain and wheels/tires alone.
Conserve	348	375	405	8%
AP	328	353	371	5%
Sport	318	342	??	??

Not a massive improvement once accounting for the battery.

Comparing the specs for the 20" wheels i thought might be a better comparison but again the tires have changed to ones which may also have a reduced rolling resistance over the OEM gen1 models:

Drive Mode (rivian defaults for height etc)	Gen1 Quad R1T Range Advertised	Gen1 Quad R1T Range scaled assuming 141kWh battery	Gen2 Tri R1T Range Advertised	% diff based on drivetrain and tires alone.
Conserve	??	??	??	??
AP	284	306	329	7.5%
Sport	??	??	??	??

It would be great if we could get a real world comparison with the same wheels/tires on a gen1 and gen2 to actually understand what the efficiency of the new drivetrain is - especially when we start to see the new gen2 quad next year.

sorry for the delay here. This is what my Tri-Max shows for max charge miles.

something tells me Rivian will reply with some sort of comment that this can’t be the holy grail because it says “based on your driving history”

let us know what you hear.

I had mobile service out yesterday. They proactively changed the 12 volt battery in my R1S. The tech said he was the one looking into why the range didn't show what Rivian advertised on my tri max. He said they had delivered very few tri max trucks, but said they knew it wasn't showing the range it should and he would be escalating it to the factory if other tri max trucks showed the same and yours is exactly the same as mine. He thought they would have to get the calculations correct because the can't advertise 371 miles of range in all purpose and then deliver them showing 346 like yours and mine. So I think it will be addressed.

I hope this gets fixed, as this is showing the new ascend motors to be less efficient per kwh than the original gen1 quads:

Drive Mode (Rivian Defaults for Height, etc.)	Gen1 Quad R1T Range Advertised (mi)	Gen1 Quad R1T Range Scaled (141 kWh) (mi)	Gen2 Tri R1T Range Reported (mi)	% Diff Based on Drivetrain and Wheels/Tires Alone
Conserve	348	375	395	+5.3%
AP	328	353	346	-2.0%
Sport	318	342	341	-0.3%

What is the source of that data?

Wayback machine for the Quad Ranges at different drive settings.

I've redone it with what my own R1T is displaying after 17 months of lead footed use, and fixed the max batter size to match the gen2 size - which certainly makes things look a bit better:

Drive Mode (Rivian Defaults for Height, etc.)	Gen1 Quad R1T Range Reported (131 kWh) (mi)	Gen1 Quad R1T Range Scaled (140 kWh) (mi)	Gen2 Tri R1T Range Reported (mi)	% Diff Based on Drivetrain and Wheels/Tires Alone
Conserve	347	371	395	+6.5%
AP	316	338	346	+2.4%
Sport	311	333	341	+2.4%
