  1. PC MAG: Rivian, Tesla, and Ford are embracing LFP batteries...customers aren't told which type they're getting

    No, it wouldn't be hard to check either, LFP batteries with similar range are about 30% heavier. They also have poorer cold weather performance, but there are advantages too. They're safer, less susceptible to thermal runaway, and have extremely high cycle life even when stored at high charge...
  2. Rivian vs Tesla vs Frigidaire?! (Average annual electricity consumption)

    It's still a valid comparison though. If your gas powered vehicle can't fully utilize the energy in gasoline it's not the fault of gasoline, it's the inefficiency of the vehicle. The energy is still there and being used even if it's wasted. Electric cars are simply much better in that respect...
  3. Newest "Now You Know" Video focusing on 12v battery issues in Rivians

    They didn't compare their service responses, they described a bad experience where they were told incomplete/incorrect information, had their car towed by someone who had no idea what it was, and multiple times where it had died and been undriveable. I did watch (most) of it and even if the...
  4. One Pedal Foot Exhaustion

    I've noticed (and I can't tell if it's just in my head or real) that if you have regen set to 'high' it takes more force to keep the pedal at a certain acceleration. I usually don't use it like that unless I'm in heavy traffic, but has anyone else felt the same thing?
  5. Some Quick Math on Electrical Grid CO2 Emissions and Vampire Drain

    I think that's a fair bet, my energy delivered as measured by the EVSE is about 9-10% higher than what the car is saying it's getting and that's right in line. I'm not sure how much of that is inverter loss so DCFC might actually be more efficient in terms of power delivered because the inverter...
  6. PSA: don't slam your gear tunnel doors!

    I just palm the door and 'throw' it into place. Haven't had a problem with any warping/bending but it's a pretty common way of closing doors to prevent having to 'push' on any particular part and apply more force to it. I wouldn't really call it 'slamming', but it's more force than gently...
  7. What I like least about my R1T

    I realize I'm skipping all the comments here to reply to the OP but I'm not sure this could be further off the mark. It's never going to feel like a miata but compared to every other vehicle in this class I think the driving feel is top of the pack. The fact that there's any steering feedback in...
  8. Windows not rolling all the way up *FIX*

    They took apart my damn door to fix this one and I could have just done this? Silly, feels like it creaks more now too.
  9. Charging to Optimize Battery Life - What's Your Strategy?

    Almost universally the best way to reduce calendar aging is to maintain the lowest possible charge level, although the benefits in trying to 'maximize' this life diminish as you go lower in charge level (Chemistries are obviously going to vary somewhat but here's an actual paper on it.) Low SOC...
  10. Will these work for the 22s -- Pirelli Scorpion AS Plus 3 tires

    If you can find SLs that can handle stock inflation pressure more power to you, I just found when I was looking they often didn't meet it (most fitments were XL range tires.) That said it seems to be inconsistent across brands and makes, and I'm surprised to see ours is SL (although given it's...
  11. Michelin Defender tires installed on 20" wheels

    I wouldn't use SL range on this truck. Most SL tires can't handle inflation pressures above 42/44 cold, so they'll wear excessively and reduce range on our vehicles.
  12. Regen braking in conserve mode vs other modes

    Front brakes typically do 65-80% of the work when normally braking, and the actual bias won't be noticeable if you're not in a traction limited scenario. If you're on a slick surface or dirt you can notice because the car will 'push' a lot more especially if braking and turning using front...
  13. System Fault, then no heat

    That's a new one - I really wish there was some more detail on what went wrong in these cases because seeing major systems fail and "service your vehicle" isn't helpful when you're nowhere near it. I've left mine in the cold at 0 and below overnight and it's worked perfect every start, but...
  14. Rivian, please ”add” a power button

    In my last car I never need to take the keys out of my pocket. A regression to that behavior (with a bulkier stupider phone) is not an improvement. I'd love to be able to force things "off" so I don't need to go into the climate menu and turn it off and turn off my music so it doesn't randomly...
  15. Vampire Drain - 4.57 kWh/day, 8 miles rated range per day

    One thing that I think makes it hard to quantify the drain is that coming from a drive cycle and storing the car especially outside in the cold could lead to a lower voltage reading on the cells without really using energy. It's extremely hard to quantify charge levels across a temperature swing...
  16. Vampire Drain - 4.57 kWh/day, 8 miles rated range per day

    I think leaving it plugged in especially when cold (<50F) is not ideal, because the truck needs to warm the battery in order to be able to charge it at all, but since you're charging 1-2% at a time most of that heating is wasted over a long period instead of just for a few hours while it charges...
  17. For those who got R1S (or R1T) at original approximately $78k would you buy one for new price of approximately $93k?

    I don't think I would - although it's really not an indictment of the car so much as the fact that $95k is a ton of money for *any* car and I don't think i could stomach it. Everyone's so careless on the roads or in parking lots and I can't stand the thought of daily driving that much car. For...
  18. I designed some 3D printed window shims to fix my Driver's side wind noise

    Interesting I might need to give this a shot. I get a little wind noise but never noticed anything 'loose' and its still quieter than many other cars so it didn't stick out. When you just used tape did you just stick it over the gap or were you specifically trying to hold that trim piece down...
  19. 21" to 20" wheels switch -- never-ending drama

    They only pick OE equivalent wheel sizes - to my knowledge Tesla doesn't let you just input a tire size and there's a lot of variation in tires on a particular wheel. I'd like to change mine to 275/60/20 or 275/55/20 when I need new ones, but it's the same wheel.
  20. Official Rivian Email: A Look Ahead to 2023. Rivian Membership cancelled and unbundled into subscription services

    Yeah if they're going to charge me for the modem I'm disconnecting this thing from my own wifi - they can pay for all the data they want to send back to the mothership. I'm not paying another sub for data when I literally carry a phone everywhere, I'll just switch to a car that lets me use that.
