I'd be shocked if it's anything but, in particular the 800v bit given the huge battery. Charging 180kwh on 400v could be painful. In fact, I suspect they are related, and the delay is owing to expected completion of the dual motor/Enduro development (all dual motor also now 2024). The in house motors are more compact, providing more room for batteries.
There are 800V vehicles that only charge at the same kW rating as the Rivian at 400V. (Kia EV6/Hyundai Ioniq 5/Genesis GV60 top out at 230 kW, barely more than the 225 kW I've seen my Rivian take.) The Hyundai Group vehicles are small efficient crossovers, so that 225 kW is a *huge* amount of miles-added-per-minute, compared to the relatively inefficient (due to being a big powerful truck) Rivian, which at the same kW-input rate is adding fewer miles.

800V alone doesn't make for a faster charging experience. That said, because we know Rivian has experience with battery packs capable of accepting 500 Amps, there's a good bet that a Rivian 800V system might get a full 350 kW.

On top of that, it only even really helps at 350kW stations. My first towing trip with my R1T I had a painful experience stopping at a 50kW station. An 800V architecture wouldn't have helped there. (Or even a 150 kW station. Although a max pack R1T would have given me enough extra range while towing to make it to a 350 kW station.)

Huh, take it back then. Dual motor expected to be ready by Summer.
That'll make my brother-in-law happy, he has dual+max configured.

Looks like GM will be first with a 400 mile truck. Maybe first 2.
Frankly, given the size they are working with, all the full size trucks should be easily capable of having a 400mi battery (but still offering smaller for price point). I think it's still what kind of truck do I want (size, features, etc.), then picking a range. A 1,000mi Lightning for the same price as a Rivian would still not interest me. A 400mi Ranger for a reasonable upcharge would be very interesting. Rivian doesn't have anything to worry about until they start making EV Rangers, Tacomas, etc.

It's worth noting that for now, any Rivian lifers that have been waiting for the Max, can't simply downgrade their powertrain to a dual motor, as our pre Mach pricing doesn't allow us to choose that configuration. So to get a max pack earlier, you have to change to dual motors, technically you'd have to create a new preorder, or have them add it to your account, likely at an additional cost.

What the royal F, Rivian?!

This almost certainly means I don't even get the chance to buy another Rivian.
And R1T only?
… then make the R1S in the full length wheelbase.

By 2024 – pardon my tmesis, but – it's a-whole-nother ballgame of electric vehicle technology and there's just no way of knowing what technology will be in an EV battery. It won't be a 180kWh slab of 2170s or probably even 4680's, it's going to be LFP or any one of the "this changes everything" technologies that gets announced seemingly every week for the last year.

Far out.

Has Rivian quiet-quit the R1 (and all of their consumer vehicles including the R2?) in favor of delivery vans … and electric bicycles?

I'm too miffed to correct the punctuation of my post!

Well sure, but we're not comparing to Hyundai. If Rivian is pouring money into 800v R&D, you can surely expect that it comes with charging speed improvements vs. the status quo. I know there are other potential benefits, but that's the primary one and the only one that is really marketable.

Also, the smaller size of the battery for those other vehicles is a limiter on how fast they can charge. A 180kwh (twice the size of those), 800v battery system should be seeing 300+kw.

You're right about the 350kw infrastructure though. But, that will be increasing, including Rivian's own network. It's still something that won't make sense/be worth it for everyone, especially with an added cost factored in. I personally wouldn't pay much of anything to charge faster than I can already, because I don't do it often.

Silverado SOP is supposed to be March 1st of next year. Sierra forecast is not until October, but if Rivian's delivery dates for the Max pack aren't until 2024, it indeed seems likely they will both be shipping already.

Ram is actually forecast to bring their BEV and Range extended 1500 to market before the end of 2024.

Ford was smart to get some early market share with their current Lightning, but it looks like they are going to cancel the program very quickly after the new plant is up and running with the ground-up design.

That doesn't sound right at all. I have a "day one" R1S order and it is "noted" for Max Pack but there was at the time now way to actually order Max Pack. I have a day-one R1T ordered with the then promised Max Pack and that was built without the Max Pack. The Max Pack was offered as a $10K checkbox.

I switched to a large pack. I don't need the Max Pack (though it would be awesome,) and hope to get delivery sooner. I was still hoping for late 2023 (early 2022 order) but now I'm guessing it won't be until late 2024. We've been sharing a vehicle, so... ouch.

It would have been really nice if for the first couple of months they updated the estimates monthly instead of quarterly. They could have predicted a ton of changes once they got a real estimator out, and it's going to be really annoying waiting to see if I ended up at the back of yet another line.

Earlier this spring I spoke with someone - off the record - who had been at Rivian for at least 5 years. He told me that if you want to actually get the truck, don't wait for the Max. Other than a test mule here and there, they haven't done much with them yet. The at-the-time estimate of 2023 deliveries he believed was just the temporary "kick the can down the road" placeholder for Max packs before they could kick the can a little harder. Looks like he was right. Hopefully there's a chance the Max pack benefits from some different architecture and battery tech.

I switched to a Large pack, got my truck, and recently got nearly 350mi on a single charge of freeway driving so I was happy with that.

I think all the Max Pack preorders deserve an explanation from Rivian at this point. If it isn't going to be the new 2nd gen 800V architecture with Enduro motors I'm not sure I'm going to wait that long to get one.
As a Max Pack preorder holder since March 2019, I agree.

I really do wonder if they will ever build it.

And, let's say they do deliver it in April 2024. I will have waited 5 years! I must be nuts.

Well, time to go look for a clean used ICE pickup this weekend, no sense trying to nurse the old ICE P/U any longer.
