Sure and I appreciate Rivian is buying at scale, with long lead times on parts. What I am saying is there's some strong arguments to be made for switching. Their service centers are clearly struggling, 12V battery replacements soak up man hours, they also result in unhappy customers. Having...

That's an outrageous price for brake fluid. 3 x 1.5L is still a lot of fluid, I typically use maybe 1.5L when doing a brake flush. Good to know the 1108 works for Rivian, I have that Motive brake bleeder kit, makes the whole process pretty quick.

It's wild to me all these 12V issues with the R1S/T. I realize the Sodium 12V are a bit more expensive but you would think they would switch to them, update the firmware to correctly support them and then have far less service appointments + happier customers. Surely the reduced demands on...

Shoot I think I made a mistake, I think I found a 275/55R20 by mistake.

Looking at potentially fitting Michelin Defender LTX M/S2 in slightly larger 275/55R22 on my wife's R1S then setting the tire option to 275/65R20 to closely match it. I want the extra sidewall and comfort but don't want to have to buy the 20" wheels.

Oh nice, are they 275/65R20? What sort of efficiency are you seeing compared to stock Pirellis? I take it NVH is markedly improved?

Wow, that's incredible efficiency. Do you have the right tire size set? Almost seems too high. I'm still going for 275/65 as I want the additional side wall for comfort and impact resistance.

I'm 6'3" and had no issue fitting in any row, the third row while not huge is fine for kids. I'd personally like to see tilt forward 2nd row seats so 3rd row access is easier when there's a child seat in the 2nd row.

They are going to not upgrade the R1 until 2029? What planet are you living on? I would bet the house that this is flat out incorrect. A lot of the previously discussed upgrades, 2nd gen heat pump, steering wheel, drive compute should be close to drop in upgrades. This doesn't require a ground...

BYD is hemorrhaging cash despite record sales - Berkshire/Buffet has sold its stake in BYD, Geely is starting to sell stakes in Volvo/Polestar to free up cash after disappointing sales, hardly the most rosy outlook. I think they are smart with capable engineers too but much of their price...

2.5mi/kWh is pretty good, that sucks about the wheel shaking. Could it be worn suspension/drivetrain components? Never had an issue with steering wheel shake on any large SUV I've owned, I don't know why Rivian has such an issue.

Sure, it's called Lucid Gravity, but I'm not into minivans.

I'd like to see this too.

True but BYD owns the entire stack from cells to vehicle and operate at huge scales with huge subsidies (their finances are pretty bad). The CCP/BYD/Geely etc are playing for market share, not profits, Rivian can't do that.

Resistive heating losses are directly tied to the current being pushed in, with 800V you can use the exact same cells but deal with lower resistive heating, even at higher power levels. Switching to a new cell would likely see even bigger improvements was all I was saying. My point still stands...

Yeh I usually swear by Michelins after being burned too many times by other manufacturers (Pirelli). Were you using the Pirelli ATR+ 275/65R20 before? How does the efficiency compare?

In the small print they will swap them for another set of Hankooks, so not really much of a trial.

While I agree they would need to change the pack cooling, it's incorrect to say the charging speeds would not improve much. The cells would be dealing with half the current and thus much lower resistive heating losses. If Rivian combined a newer 21700 cell like the LG M58T with a 800V pack they...

This was my point, a lot of the upgrade work has already been done for the R2. Drive computers, gen 2 heat pump, steering wheel etc, all of which should be close to drop in replacements for the R1. I don't see a huge model refresh, but it makes sense from a cost perspective to align your parts...

Sure it would be nice, but the electronics for an 800V add to the cost of the vehicle and the R2 is very much aimed at a more affordable price point. I'm sure it'll happen eventually as costs come down. An interesting thing is a lot of the newer datacenters are switching to 800V DC supplies to...
