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

[DuoRivians]

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

The math of dividing the total distance by total energy probably isn’t right. The total energy likely includes energy spent on stuff like hvac, computing power, etc

I want to add here that my wife agrees and disagrees with me on Max pack. She agrees it's not much difference and she also agrees it's a lot of extra money. She said she would likely go for it because while the amount of time saved is small it will accumulate as you own the truck and continue to take trips.

We figured that if we were towing we could potentially save 15 minutes each way or 30 minutes each trip. We take about 10-12 trips per year so we could save 5-6 hours per year for each year we own max pack.

I still wouldn't pay the 10k but my wife said she would. Hopefully this helps some folks make the decision. There may be some value in towing with max pack after all.

It also helps with the degradation losses. No one ever wished they had less range , especially when towing with an EV. Disconnecting to charge just sucks, glad I haven't had the pleasure yet.

Data would say degradation is steeper though.....

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 DM has a better payload & very few of the MP have a spare/RUS/PTC so payload would still be above 1400lbs.

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?

Disregard the R1S, if they want to sell a real max pack for it put it on the T chassis & have a R1S XL.
Weight is an issue, since it kills payload.
we know the modules are approx 195lbs (or less) The MP has 142kwh net (usable)so:
10 modules = 158kwh usable & 1945lb pack
11 modules = 173kwh usable & 2140lb pack
There is no room for a 12th module so that is as good as it gets, no 200kwh gross as it is too big & heavy.

They could probably do 11 modules and no skid plate, but re-tuning the suspension will be hard.

Retuning suspension for 5% more weight will be hard?
Really no different than a spare/RUS/PTC, having a couple passengers or payload/tongue weight.

They may just accept the 900 # payload, and likely reduced SAE tow rating, but increasing the GVWR down the entire line is often more engineering intensive that it seems, even if its only 200#. Sometimes it's a suspension tuning, rigidity of a part, or simply tire weight ratings push them to LT tires.

Only a very small % of MP have RUS/Spare/PTC so sans those items:
11 module, 173kwr usable
1792- 390=1402lbs>900
1748-390=1358lbs>900
10 module, 158kwh useable
1792-195=1598lbs>900
1748-195=1553lbs>900
Keep the GVWR the same & the payload is still same or better than the full size GM offerings and in line with the midsize offerings.

My problem is lack of range whether you tow a trailer or not. I am in Arizona and no longer tow from Phoenix to Lake Havasu City. The infrastructure to charge is just simply lacking and only adding more (liable) chargers or have an increased range can change this.
I hope in the future, there will be more (reliable)fast chargers or more range out of the battery pack.
Love the truck and would get another if that were solved. And, unhitching the trailer to charge is a real pain.
Range anxiety has returned!

Anyone know if the EPA test results are with the HVAC off?

5 cycle testing, so includes tests with HVAC usage.

Nice numbers! Since temperature has a big impact, how was the weather?

Weather was little cold, HVAC running heat at 75 degrees.
