I would also be interested in how much these tailgate scoops help drag and efficiency.

It's to reduce the base drag from the square back. I wished the R1S had this but since it does not, I have put vortex generators on the roof top up stream a bit to reduce the base drag. The drag is caused by adverse pressure gradient due to flow separation behind the vehicle.

If coupled with a controlled diffuser, it can significantly lower the overall drag of the vehicle. What people often see in on the race cars are to increase the downforce. The diffuser to lower drag would not be as big and mostly to control the flow direction rather than lower the underbody pressure. Rivian has filed for a patten on deployable diffuser that gets deployed at the freeway speeds - sort of like how Porsche has a rear wind that deploys at speed, except this is for below the bumper.

I agree. I'm having a major dilemma after this leak. I was determined to hold on to my 2022 LE R1S until Gen3 autonomy hardware arrived but now I'm tempted... What does the group think, wait for Gen3 or go LE R2?
There really isn't enough detail on how far Gen 2 can go and how soon lidar software with more advanced autonomy will be ready after it comes out. Even the launch date for lidar release may have moved by a few months. At first they said late 2026 and now RJ has recently said early 2027.

People on the fence just have to wing it and make a decision or wait until Rivian gives more granular detail. Will be interesting if they talk about lidar tomorrow (i'm guessing not).

I think ultimately, their bread and butter (majority of sales), will be the standard RWD R2 with 345 mi range. Because range anxiety is a thing, real and imagined. People will stretch themselves to get it. And at just over $50k after destination and fees/taxes, it's right at average transaction for a new car in 2025. This proves how smart and deliberate Rivian is with pricing/planning.
Rivian R1T R1S 2026 R2 pricing, range & specs! $57,990 Performance Launch Edition / $53,990 Premium /  $48,490 Standard / $45,000 Standard (Smaller Battery) this (1)

Interesting - I never noticed that R1S didn't have them. Assumed it did, because R1T does.

I would not count out the R2 Base. There are those people who might be able to make that $ work and take advantage of writing off the loan interest on their taxes. Makes a big difference for the bracket of earner. Quite different than a traditional higher income Rivian buyer to date.

I do feel that NO EV Vehicle should be sold today with less than 300 mile range at a minimum but that is just me.

Maybe it's because in their wind tunnel work they didn't see enough of a benefit. R1S and R2 aren't equals. R1S is longer and taller. Adding vortex generators is interesting. But... where's the observed result?

Meh. That’s a stretch…
Tax incentives don’t really count. Tesla didn’t really “offer” it at 35k. They cheated on that one
I agree, otherwise I really stole my R1S quad at 71,500 (79,000-7500), honestly I feel like I stole it even at 79k….

And legacy auto will keep doing this until they stop making ICE models... which probably won't happen in my lifetime. 800V architecture is cool, but 5~10 minutes less per DCFC session isn't going to make a whole lot of real-life difference. Only better battery chemistry and charging tech could make a greater dent in charging times. Until then, more charging opportunities, i.e. infrastructure, would make EV life better.

And BMW's fast charging claims on the i3X is possible only with higher spec fast charger, which isn't yet common. And, we don't know what impact that high charge rate has on pack longevity.
Fair points, 800v is nice but how much real-world time is actually saved? I like the look of the iX3 and I do miss BMW ownership (330i ZHP for 10 years then three BMW i3's between my husband and I), but I'm really into the Rivian ethos, outdoorsy, adventurous. I noted elsewhere that as charging stations get closer together EV owners might consider only charging to ~50% (from 10%) and moving on, more stops but less time charging, not sure which would be more time efficient. As it is when we travel in our Equinox EV, by the time we let the dogs use the restroom and use the restroom ourselves we might have 5-10 minutes before we're at 80%. If we are also stopping for a meal during a charging session we have "wasted" zero minutes charging.

There was at least a six-month period last year when you could get the Model 3 RWD with 363 miles of range (not the stripped model) for $35,000. It was $42,490 - $7,500 tax credit at POS = $34,990.

Yeah, I at least certainly don’t consider and offering that included an expected $7500 federal tax credit that didn’t apply to everyone as achieving delivering a $35,000 car.. and to be accurate when the $35K car was announced, there were no longer tax credits for TESLA at all.. they had worked through their pile of available tax credits and it was prior to the IRA which unlocked new tax credits. So their company’s’ purported $35K car, should have been just that a $35K car.

I used to think like that but not so much anymore. On long trips I typically stop every 100-150 miles to stretch my legs. I have a 10 year old Model S that gets 170 miles at 80% and took that on a 7500 mile cross country trip last July.

Long range and fast charging numbers are great for specs but in the real world for day to day most people don’t use either of those.

What is “Semi Active suspension”? For us mountain rural folk 9.6” will be dragging the battery on rocks.

I'm assuming, the rwd 2027 comes with lidar...right?

I was a long time BMW fan. Still have one ('01 M Roadster). I gave them benefit of doubt when Chris Bangle took charge of design and introduced his controversial Bangle-Butt. But when his successor gave us and doubled down on giant buck-toothed grille, I was done. Plus, BMW engineering has a special talent for complicating the uncomplicated. When the motorized glovebox failed on my '13 X5, I learned it wasn't just a simple spring dampened soft-open mechanism. The glovebox assembly included some weird infra-red switch/sensor. Why on earth? The total bill was close to $700. Luckily BMW covered it under warranty. And full brake replacements on the X5 every 2 years was a bit much.

As for charging times... I think the topic is charged (pun intended) full of misinformation and ignorant hot takes. Daily, each of us easily waste far more time consuming social media than what it takes to complete a DCFC session. I usually use my DCFC sessions to catch up on reading and the time passes quickly. If I had 800V and shortened it by 5-10 mins, it really wouldn't make much difference.

You're talking about ground clearance. Unlike R1, no R2 has adjustable ride height since it does not have air-sprung suspension—spring height is fixed. "Semi Active" likely refer to adjustable dampers, with which compression and rebound damping of the shocks can be adjusted independently and on-the-fly; to control ride quality as well as stability. But we will all find out tomorrow.
