    Sport Mode vs. AT Mode efficiency?

    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...
  2. 22” Continental Terrain Contact A/T tires resulted in a negligible INCREASE in efficiency (2.07 mi/kwh) compared to OEM Pirellis (2.04 mi/kwh)

    My OEM 22ā€ 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...

    Efficiency and Range Numbers Don't Add Up

    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...

    Range and energy usage doesnt seem up to add up

    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...

    Best speed for maximum range in R1T?

    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...

  9. Conserve Mode Efficiency Improved? Rivian R1T real world range on a 900 plus mile trip averaged 2.7+ miles/kWh

    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 improvedā€¦ and then this video popped up on recommendation that tells a similar storyā€¦ Tl; Dr is that this guy did 2.77 miles/kWh on 22s...
  10. 3400 Mile Road Trip Charging Performance Report

    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...
  11. Speaking Efficiency - How we perceive efficiency in EVs?

    Hi there Rivian Forums Community, Iā€™m kindly asking for your voice! Iā€™m currently conducting graduate research on the expression of efficiency metrics in electric vehicles. As part of my research, Iā€™m hoping to learn from driversā€™ experiences and use my research to amplify driversā€™ needs. I...
  12. In need of more competitive range and motor efficiency compared to newly updated Tesla Model S & X ?

    I just saw the news on the updates Tesla made today to Model S and X. The electric drive units seem far more advanced with higher efficiency despite still using same battery pack size (100 KwH) and much more range than before (325 miles in the Model X using 100 KwH battery pack). Is it possible...
