  1. Quad motor vs locking diff

    Yes, that is another facet. Here are a few posts I made last year about the topic: https://www.rivianforums.com/forum/threads/rivian-off-road-struggling.5026/post-136087 https://www.rivianforums.com/forum/threads/rivian-off-road-struggling.5026/post-136410 Basically once you start losing...
  2. Rivian battery overheating during charging in cool weather

    . Wow this is pretty bad. 96 kW charging at 30% battery capacity on a 350 kW charger on a 37F day. Has anyone else seen this bad?
  3. Quad motor vs locking diff

    Except the difference is one may get you from point A to B and the other may not. A vehicle with three locking diffs will still get you anywhere a Rivian can on the road. But a Rivian most certainly cannot go some places the three locking diff vehicle can go. Yes, of course the Rivian is going...
  4. Quad motor vs locking diff

    Not when you have 300+ lbs of motor rotor, gears inside the gearbox, driveshaft, CV's, bearings, brake disc, wheel and tire inertial mass to move per corner. Nothing is super quick accelerating and decelerating that mass.
  5. Quad motor vs locking diff

    Ya but this particular issue is manufacturer independent and will affect all off-road EV's that don't have mechanically locking diffs. The easiest way for me to boil down is; when you have three locking diffs, the entire driveline is working in unison independent of traction. Therefore, any...
  6. Quad motor vs locking diff

    I forgot to mention one thing, the Hummer EV that has a rear "E-locker" with two motors on the rear axle also suffers from this issue. It's not just Rivian, but will be all EV's that don't have a mechanically locked differential (the Hummer EV does have a FRONT mechanically locked diff). In the...
  7. Quad motor vs locking diff

    It's extremely stressful on components, wastes a ton of energy, generates a massive amount of heat, is dangerous, and brakes typically don't have the fidelity at near release friction coefficient which is different on every wheels brake disc.
  8. Quad motor vs locking diff

    No you cannot. Exact same power to each wheel would make each wheel spin the same speed if the truck was on a lift. As soon as one tire touches the ground, the power to continue rotating (and hence moving the vehicle) DRASTICALLY changes, instantly. Now for example you have three free spinning...
  9. Quad motor vs locking diff

    I've already explained why a quad-motor Rivian will never be as good off-road compared to an off-road 4x4 with center, rear and front locking diffs in the off-road section. Rivian quad motor acts more like a "good" AWD system. That is why it struggles even over some pretty small/basic obstacles.
  10. Ride quality R1S vs R1T? Should I be worried about reviews?

    Exactly. Other manufacturers are producing in very small quantities compared to Tesla. Also, 2023/24 recession is going to GREATLY limit the amount of people looking for a $100K SUV/Mid-sized pickup that Rivian offers.
  11. Ride quality R1S vs R1T? Should I be worried about reviews?

    I completely disagree. Tesla's price cuts were a dominance power-play. Also, because their margins were so high, they could do it. Other/Legacy auto makers are now sweating in their offices, BAD. Tesla has 2/3rds of US EV market share now. I expect that to go UP, not down, after their price cuts.
  12. Tesla Price Cuts Across The Board

    If you are talking to the guy from the tweet, should probably go on Twitter lol.
  13. The Rivian R1S Destroys The Tesla Model X (I Own Both) - Owner's Delivery Review

    My friend had an X for like 5 years and I rode in it quite a bit. Never impressed me and I think it was/is way over-priced. Definitely Tesla's worst vehicle.
  14. Tesla Price Cuts Across The Board

    It is good news I think for Rivian buyers that actually want to use their vehicles. As the Tesla price reductions cut the knees off their competitors, this means people buying Rivians just to flip will dry up as their used values continue to decrease. As will the weak economy coming over the...
  15. Ride quality R1S vs R1T? Should I be worried about reviews?

    Ya if Tesla came out with a true mid-size SUV that could off-road, they would absolutely dominate. There is a big gap in their portfolio. IMO the X is a silly over-priced vehicle, the Y being a great value but too small and basically no off-road capability. The Cybertruck is coming but not...
  16. R1S Auction Prices Coming Down

    I just won this auction for $75,651.51!
  17. R1S Auction Prices Coming Down

    I wonder if people are trolling him. Obviously this transaction will go nowhere.
  18. Tesla Price Cuts Across The Board

    Thoughts?
  19. R1S Auction Prices Coming Down

    Ebay doesn't care about any of that crap as long as they get their money. I see used vehicles being listed as "new" on that site all the time.
  20. R1S Auction Prices Coming Down

    I see. I wonder how the IRS would prove though that you just bought intending to re-sell versus getting the vehicle and just saying you "didn't like it".
