Rivian Max Pack EPA Data (document shows 141-142 kWh usable battery)

[Epicloop]

I'm not sure, but I think MPGe includes losses incurred from level 2 charging. If that's the case, a more efficient on-board charger could also help the Max Pack numbers. I agree that a rear SiC inverter is also a possibility.



This is an important thing that get's lost in the conversation. Extra range is of less use if it eats into the payload. The Hummer EV has a giant battery and the payload is 1300 pounds. The long-range Silverado EV WT isn't much better at 1400 pounds. My R1S MP payload is 1779, so there's plenty of capacity for people, gear and tongue weight because the battery isn't much heavier than the LP. Not to mention that a physically larger MP wouldn't have been possible in the R1S.

I would buy the R1T with 2 more modules for (149/9=16.55X11=)182kwh (&800V) over the GM options that have the same or less payload.
If a full size truck will sell with 1400lb payload so will a midsize.

My truck only has 1400lbs of payload with the large pack. Add two more modules that probably becomes a ~1000lbs.

So as long as you don't want a spare tire, RUS or power tonneau it's probably ok but for me it's a no go.

Edit: Just looked and Munroe quoted the weight of a large pack at 1750lbs so its even worse than I thought.

The crazy range on the Silverado EV is there for one thing. Towing.

I would be open to paying up for a bigger pack but it would need to be something larger.

Silverado EV has a 200+ kwh battery so at 1.1 mi per kwh I would be able to get about 220 mi towing range. Charging port on Silverado EV is in a bad location. I love everything about the Rivian though.

Larger than1 182kwh?

Larger than1 182kwh?

You read my mind. At 1.1 mi per kwh that would give me 200 miles of towing assuming I could use all 182 kwh. Realistically it would be like 180 miles because I wouldn't be running it flat from 100%.

Right now it's ok with large. I go about 120 miles. I might be able to stretch it to 140 if I wanted to run the pack completely flat.

A 200 kwh pack would be a real winner IMO. Though I'm not sure if they could package it to fit in the S or the T. The weight changes all sorts of things. To tow longer distance you need more battery and more battery adds weight which reducing payload and towing.

That makes it 195lbs per 16.55 kwh MP module. Maybe a 10 module pack as a compromise,
I would be curious to know what a 1/2T motor, radiator, transmission, transfer case, drive shafts, exhaust, & tank of of fuel weigh.

If I divide 1750 by the gross capacity (141 kwh) I get 12.42 lbs per kwh. Now adding modules will not be completely proportional because there are additional components in the pack that will not change but using this number 200 kwh gross pack would be estimated at 2,484 lbs so an extra 734 lbs over large pack.

I don't think weight is as much a problem as the packaging. In the R1S there is just not enough room. In the T even if it fits what will the reduction in payload and towing capacity look like?

I haven’t seen quad 21s get 2.4 mi/kwh, unless limited to exclusively conserve mode.

Unless you can find a car that’s a dual motor large pack, which I haven’t seen shared by anyone, you won’t know how/where the efficiency splits when looking at max pack only, since max pack can only be configured with dual.

I have 2.43 lifetime (6800 miles) in my quad 21 T. I never use conserve.

I wonder if there are tricks Rivian can play here to increase EPA, like:

• a different gear ratio, running the motors hotter
• engaging auto-conserve at a lower speed threshold
• better ball bearings/wiring

... and then paying for the increased warranty costs with the higher vehicle price.

It's not reassuring that Rivian is supposed to put out lower cost R2s at volume and high quality, but:

• the original R1s were delivered years late and had tons of initial quality issues
• Rivian can't even modify their original product to add a meaningfully larger battery pack

In summary, don't think the Max Pack débâcle predicts a smooth launch of the R2s.

I’m actually at 2.63 now.

The math actually comes out at 2.54 but still impressive.

What tires are you on? Do you do mostly long drives?

On 22s I get a lot of 1.95 to 2.0 because we do a lot of 3 to 5 mile drives around town but on trips we do much better.

Edit: nowhere near your numbers but between 2.2 and 2.3

Here is the Rivian R1T loaner showing 2.67 mi/kWh with 20” All terrains.

That average is even further off, you divide the miles by the kWh it is 2.01.

They’re not fake miles. Don’t get the max pack. No one is telling you to.

Duorivians your answers are usually sort of … don’t like it don’t get it ! How is that helping anyone? Rivian or their consumers? This forums are to have educated discussions/conversations or so I thought

I think I mentioned this in great detail before, but for me it's all about Rivian setting expectations. It would be one thing if we were basing expectations on our own assumptions, but we aren't.

I think @DuoRivians / @DuoRivian is right, if you don't like it, vote with your wallet. But Rivian needs the feedback on some level, to know the reason we don't like it. It's often not the feature itself persay but the way in which the implementation/timing/detail of it changed for the worse.

Tesla stumbled a whole lot in the beginning because they built up all this customer goodwill and fanbois army. So when they misstepped, they couldn't hear the constructive criticism over that din of excitement they also created.

Are you the fake account created by Supra who has made just one comment here? In case you must know, this comment was aimed specifically, solely at this one guy

See the comparison of dual motor large pack versus dual motor max pack. The only difference is the battery pack.

If you’re going to resort to cynicism as the answer to what you might not know, that’s not productive at all. Worse, if you extend that cynicism to everything else because it’s convenient for your point of view.

We’re tying to understand how, short a tear down analysis
