Announcing our new "CLUBS" section where you can join or create a Rivian club or group! You can use this new feature to conveniently plan and discuss local events, gatherings or other club/group related topics.
So we encourage you to join (or start) special-interest and regional-based Rivian clubs at: https://www.rivianforums.com/forum/group-categories/clubs-groups.1/
Honestly, I think the pr team is misinformed with old documentation.@Supratachophobia this article from the verge and a Rivian spokesperson had me wondering though? I’m so confused by it all.
Can't extrapolate directly from R1T Large Pack range because the Max Pack adds weight so one should expect lower miles per kwh, everything else being the same.Honestly, I think the pr team is misinformed with old documentation.
Is Max pack is 180, then the r1t would have 450 range. Plus, the r1s had a physical limitation with 3rd row footwell and max pack. Now it magically doesn't? And lastly, you don't advertise 390 when 400 is so attractive from a marketing perspective. If they are saying 390, then it really is 390 and they couldn't squeeze the 180 into it to get 400.
It comes down to the math for me and they aren't making 2 max packs. *Maybe* they are scared to say the r1t can do 450 with a 180kwh battery it would take to make it do because they don't want to gut large pack sales. Maybe. But I doubt it.
I agree that most likely the battery is just less than 180, but....If Max pack is 180, then the r1t would have 450 range.
Time and time again, weight has proven to not be an indicator/effector of range. Rolling resistance (tires) and drag (highway speeds above 60mph) are the only two things that affect range in a substantial way. A couple hundred pounds is going to be at most a rounding error of a percent or two. I wish these forums let you downvote comments.....Can't extrapolate directly from R1T Large Pack range because the Max Pack adds weight so one should expect lower miles per kwh, everything else being the same.
See, now you all are just trying to come up with any way to justify you are still getting that 180kwh, we aren't. I can't even begin to disagree how stacking a single module is going to throw a monkey wrench on cooling or how you are talking about a foot of batteries making the car ride higher by that amount.I agree that most likely the battery is just less than 180, but....
If they solved the space problem by stacking 2 batteries on top of each other, either hanging under the main battery or on top causing the vehicle to ride higher, it would increase the frontal area, and therefore increase atmospheric drag and negate some of the range gains you would expect from increasing the battery size.
Or
If the increased weight of the battery pack ate too much into the cargo capacity and therefore they needed to beef up structure and suspension to accommodate a significantly higher GVWR (with the stronger structure and suspension also increasing the weight) all that extra weight could negate some of the range gains you would expect from increasing the battery size.
Weight has a significant affect on range when elevation gain is involved especially when towing.Time and time again, weight has proven to not be an indicator/effector of range.

Towing accounts for a super small percent of EV ownership overall which is why I didn't list that caveat.Weight has a significant affect on range when elevation gain is involved especially when towing.
Again, it's not weight that caused them to make it smaller, it was physical space available.I highly doubt it will be 180kw as it simply adds too much weight & cost. The added weight is counterintuitive as it will reduce payload and likely tow capacity. I understand that each KW of cell capacity is 16lbs (30kw-480lb, 45kw-720lb) It seems that a 165kw pack (2 cells) would be a reasonable compromise and match up better to range estimates.
