All Terrain Wheel Difference from Large to Max Pack, 48 miles for $10k?

[boostincincy]

For me, the freelance world in which I live, is very different from when I ordered the truck, May 2022. Now with Leasing as an option, I'm almost certainly going to go that route, as it minimizes risk etc in the near term.

I always thought I would want the Max Pack, just to have the longest possible range. But, if I'm selecting the 20" Dark All Terrain Wheels, which is another 'must'. For the $10k difference it's only changing from an EST 307mi to 355mi. I understand all the factors at play, but based on EPA estimations, that just doesn't seem worth it to me.

Is this difference, for those who have All Terrain Wheels, seemingly accurate from either Max Pack or Large Pack owners?

I'll ask a question to hopefully help answer what you're getting at.

What do you want the added range for? Is it camping and overlanding? Putzing around town? Or thinking you'll get it on a road trip?

I live in the Northeast. I have a race car I very rarely tow anymore. (X5 is my tow vehicle). So realistically a lot of our Northeast adventures are around 150-200 miles each way, which isn't a problem for the Large Pack. But I think the Large Pack isn't big enough to tow where I tow realistically. But, that's few and far between, where are the road tripping/camping trips are more of the focus for the vehicle(aside from work commute).

Only you have the answer because "worth" is subjective, pending your usage and priorities. EPA figures are just for reference. Too many other factors involved in the real world.

ok, so you basically get 11kwh with the max pack.

The Max Pack is more efficient than dual motor large pack in the city. My theory (yet to be confirmed...) is that they stuck the more efficient front motor package in the back of the max pack as well. So if towing tends to engage the rear motor in a dual motor build you should get an increase from the 11kwh (~25-30 miles) + some from the added efficiency. In the EPA city tests it was about 9% more efficient.

At the end of the day the additional range you'll see is probably something like 18% and 13% for a full battery. If you take the rule of thumb and cut the 20" dual motor range in half you're probably at like 25 more miles on an absolutely full charge when towing.

FWIW @OutofSpecKyle said he's getting a max pack R1T from Rivian to test soon. A towing range/efficiency test may be interesting given it's not just a battery capacity increase and may be subject to whether the clutch disconnect happens when towing.

You can also get an idea of range vs speed for different wheel sizes from the EPA coast down data:

The only advantage to max pack is saving public charging time on longer road trips. It's not going to save you a ton of time, but the short amounts of time all add up over the course of weeks, months, and years. It's also slightly more energy so in theory you can stay in the 20-80% area longer.

I tow at least a dozen trips a year with my travel trailer. Towing a UTV on a flat trailer I might get 1.5mi per kwh. Travel trailer between 1-1.2 mi per kwh. Even then best case max pack gets me an extra 14 towing miles. I can't justify max pack but I know there are other folks who feel its worth it.

My theory is that Rivian was very conservative with large range estimates and is creatively optimistic with max pack range estimates.

It's going to save you some stops, because you can travel further between stops.

But it's not going to save you much if any time, because you will have to charge for longer to fill the larger battery.

True but on the final leg of the trip you may need to charge less or not stop at all. Also on certain legs where you would need to charge above 80% on large you will not need to do so on Max pack. That's where the time savings comes in. It's not going to be much but it could add up over time.

I'd love to test a max pack on a long towing trip with our travel trailer where there would be many stops. I'm not sure if ABRP has been updated yet to reflect the true usable capacity of max pack.

Like I said though for me, I would rather use the funds for charging costs. If the chargers are working properly the stops are almost too quick for us in the Rivian. We are very happy with large.

The large pack range is very conservative, I’ve gotten 356 miles with 20” ATs on a road trip in conserve. Maybe the max is too? Not enough real world data yet -

 

[Franksmartin]

I agree especially if you are using AT tires on the max pack. I mean you can just switch to all season tires and get similar range improvement for much less money.

Wow that's best I've heard. Would love that to be possible

did you mis-type 256?

ON 22's I've never gotten more than 280 on conserve and as bad as 220 with a big head wind (quad motor large pack)

Could this be, as I've read (I don't yet own the truck), that the Dual Motor configs are more efficient than Quad?

They are pretty similar in range, which is also a head scratcher as to why they don't do the max battery with quad motor, if you compare the expected range on quad motor in conserve mode with dual motor in all purpose (these modes are actually the most similar) there is not much difference(using large battery on both)
