2027 Rivian R2 EPA Certification w/ specs (range, battery capacity, charging rate, efficiency etc.)

[Gen(R3)Xer]

From what I heard, the wheels are actually the same size. It's the rims that are different sizes. So I believe they are all 32" diameter but the amount of sidewall showing is different.

Ah yes, I remember this too. Maybe the 21” wheels have a more aero design then.

Personally, I'd like to hear from someone who knows whether the battery compartment has room to expand to a max pack, or if it's already full with the current large pack. Imagine a future with a 400-450mi range R2 .

It's most likely already full - I can't imagine them not wanting to offer as much range as they can right now. It's one of the main things that the average person shopping EVs looks at...

This also reflects on the discussion regarding peak charging rate. Current Ev owners understand that max battery capacity is not as important as max dcfc rate. All those people looking to replace their liquid fuel tanks with batteries have an experience where refueling rate is consistent between vehicles so the bigger tank is always better.

Of course. That’s because no one drives the speed limit.

Yes, it’s very true.. in my 8 year old LR m3, on highway I AVERAGE 73-75, which means many spots on highway for duration of 5-10 minutes of 80-82, and some very limited amounts of 63-65..but averaging 73-75.. and my watt/mile is ~ 235w/mile.. so more than 4.2 miles per kw.

BUT when I avg 65, so spots below, few spots >70, or even just locked in at 65 for a full hour (which I’ve done, but that’s pretty painful on i-5 heading south from Bay Area to SoCal!) the watt/mile average is ~ 210, making it closer to 4.75 miles per kw, and would land total range closer to 375 - which the car never shipped with.

I’ve also done 20 miles with the car at 0% before (don’t recommend it) and hypermiling - understandably and had apparent consumption closer to 165w/mile.

So yeah, speed kills range - we all know that, but there are legitimate ways to increase it, or manage it but in our domestic highway context it’s pretty hard to do - behaviorally at least.

Respectfully, that is just speculation. Given that the R1 max pack came out much later than the large pack and that we still haven't seen a Tri motor in the configurator, I don't feel it's unreasonable to hope for an R2 max pack in the future.
While I agree with you that a larger battery would be more enticing to many buyers, here's a counterargument. Maybe Rivian wanted pricing for their initial release vehicles to be closer to their $45K base price, rather than come out of the gates with an $80K Tri-Max R2. Initially offering only one battery and one motor configuration also simplifies initial production efforts.

BMW is using the same type of cells but using 46-95 in the smaller vehicles (i3) and 46-120 (25 mm/1 inch taller) in the SUV iX3. Giving up an inch of cabin space/ground clearance for R2 would bump range to over 400 miles on the 5 cycle test. No idea if Rivian has engineered the platform to accept both types of pack but that is what BMW did.

It is speculation, but if you look at the second image in this thread ( R2 / R3 battery pack photos from RJ | Rivian Forums - R1T R1S R2 R3 News, Specs, Models, RIVN Stock -- Rivianforums.com ), the pack looks about as full as it can be.

Aren’t the wheels and the rims the same thing???

we all know in the real world the R1 cannot maintain that speed for very long

210kwh peak is fine if they can find a way to maintain that peak for more than a minute or two.

I don't know why people keep characterizing it this way by saying Rivian's peak rate only holds for a very short period of time.

My R1T will sustain a rate of >200kW from about 0% to about 45% of the battery capacity. This means I can fill almost half my battery at peak rate. I consider that pretty good. I guess they could have lowered their peak rate to 150kW then held it longer, to maybe 70% of the battery. Is that really better or is it just that it would make you feel better?

My 2023 R1S does not do this or anywhere close to it. I'll usually get 2-3 minutes above 200kw in the 20-30% SoC range, even as the only person charging at a RAN station, before it starts to derate down to 180 or so. Once it starts getting close to 70% SoC it starts to drop off below 150 so that by the time I hit 70% its in the 120 range. From there it continues to drop off below 100kw and down to around 50kw as I get close to 80%.

Current Ev owners understand that max battery capacity is not as important as max dcfc rate.

I totally disagree.

I rarely DCFC. Most of my charging is L2, so I want to go as far as possible before I have to find a public charger.

I have had some absolutely horrible public charging experiences and a bigger battery means I do less public charging. Especially DCFC.

My goal is to drive everywhere without needing a single DCFC, relying 100% on home and destination charging. That will never happen with a small battery.

I keep hoping the Gen3 R1 has a 180 kWh super max battery option. I am going to buy it.

Technically yes, but sometimes people say wheel when they mean tire.

Thanks for sharing the images. I agree that the battery frame appears full and doesn't show the extra module space I've seen in the R1 large battery frame. If there's no space for more batteries, it would seem that only a higher kW/volume battery improvement could yield a max pack. You have successfully diminished my hopes for a future R2 max pack.

@mkhuffman I tend to agree with you, but admit there will be a few with usage patterns who would benefit more from faster charging rates, like @VandalSibs. I'm one who places greater weight on capacity. I guess it comes down to the amount of home charging, the distance between DCFC stations, and the frequency of road trips that require many charging stops along the way. I usually just want to zip to the mountains (Bay Area to Tahoe/Sierras), not drive across 3-5 states on a really long haul. I'm usually doing 0-1 DCFC on the way, most often when camping/offroading deep and want a bigger buffer to run the electric kitchen for multiple days, with one 80-100% top-off in Sacramento.
If I lived in Montana or a region where DCFCs are far apart, I'd definitely choose range first; not getting towed is far more important than how long I need to wait at a DCFC station. I rather enjoy most of the forced charging breaks now to get out and stretch, pee, shop, eat, etc..
