efficiency

I know these questions have been asked before and there are some great compilation threads like this: ksurfier: https://www.rivianforums.com/forum/threads/affordable-high-efficiency-20-wheels-and-33-tires-options-275-60r20.24561/ but I am having a hard time distilling the wealth of info down...

I've already posted this over on reddit but figured I'd drop it here also. ---------------------------------------------------- So I just got these swapped in 3 days ago and took it on a short road trip. Total trip was about 300+ miles but I collected data from the two longest sections (going to...

Just curious because I have never seen my R1T give me these types of numbers (I have the latest update 2025.18.01). This is with my 20" AT factory tires that now have 13k miles on them. Granted this was for driving downhill from Leadville, CO, to Buena Vista, CO (a 2k elevation drop), but I...

Gen1 R1S and this is my second winter with the car. With the weather getting colder, I'm seeing my efficiency start to go down. I was wondering if anyone had done any studies or research into: 1. How much energy goes into conditioning the battery ready for departure? What is the ideal battery...

I've got a new 2024 R1T still riding on the OEM Pirelli Scorpion's. I expect those tires to wear out relatively quickly compared to other tires I've had on other vehicles. I like the range I get with the stock 21's, and now that there seems to be a viable alternative to them I like the idea of...

These are the battery capacities. How can they maintain the same battery ranges as gen1 Large for Gen 2 Large? Battery is down 16% and folks on Gen2s seem to be getting 2.5 miles per KWh. That’s about a 270 range when taken down to zero. That’s a decent variance over published range from...

It would be nice to NOT have a limit on mi/kWh. Appears to be limited to 4… But why? Let’s say my trip is essentially all downhill. mi/kWh could essentially be 99+ I don’t see a reason to limit it to 4 mi/kWh. Please update this in a future software update Rivian ?

Morning, all. My commute is 90% highway and I'm playing with different ways to gain efficiency. I've seen the posts saying you shouldn't run in conservative mode all the time, because it shreds your front tires. But, one of the features conservative mode does that interests me is being able to...

My OEM 22” pirellis were worn by 21k miles. Got Conitinental terrain contact A/T 275/50R22 through simpletire (and installed at Firestone) chose these based on nearly the same load capacity as OEM, deeper tread (12/32 vs 7/32) and 60K mileage warranty was a little worried about impact on...

Welcome to the trippiest club on Rivian Forums. Looking forward to talking efficiency, accessories, fast charging and everything in between.

Not sure if this is really an "issue" but the efficiency numbers for my R1T seem off. I'm in California, driving on 21" AS wheels/tires. Usually a pretty normal, slightly conservative driving style. I drive mostly rural roads and freeway (not a lot of stop lights or stop n go block by block...

Am I crazy or do these numbers seem pretty off for what I should be getting? I know driving mode, driving style, cabin heat and ambient temp are all huge variables, but getting less than 1.5 mi/kwh tells me something isn't right. Sure the first 100 mi I had some fun driving in sport and did a...

Four+ years ago CleanTechnica posted an article showing some great graphs from some great data garnered by ABRP on Tesla performance at different speeds and temperatures. It includes the following two graphs, showing that the ideal speed--to get maximum range--for the Model S100 is about 35 MPH...

Short and sweet details. R1S, 22s 80 degree weather mostly Flat Texas drive 224 miles 4pm to 8pm ( rush hour hit in Waco ) usually takes 3.5-4 hours depending on kiddo stops/food This trip was 4.5 hours. 18 min stop to charge a touch, and a 20 minute Whataburger stop. Pleasantly surprised...

The team at Out of Spec has released another video, this time highlighting range and efficiency aspects for the three stock wheel options. YT Link: Rivian R1T Consumption Test!

This weekend i had a mini trip to LA and averaged 2.6+ miles/kWh on 20 ATs with conserve mode which made me wonder if conserve mode efficiency has secretly improved… and then this video popped up on recommendation that tells a similar story… Tl; Dr is that this guy did 2.77 miles/kWh on 22s...

We just returned home from a week long 3400 mile road trip with our R1T. This is our first EV. The TLDR; the truck performed exceptionally well and charging 26 times was no hassle at all. My wife and I live in Ann Arbor, MI. We got our R1T about two months ago and decided to take it on a road...

Hi there Rivian Forums Community, I’m kindly asking for your voice! I’m currently conducting graduate research on the expression of efficiency metrics in electric vehicles. As part of my research, I’m hoping to learn from drivers’ experiences and use my research to amplify drivers’ needs. I...
