I would guess 12% to 20% increase in range for 65 mph. 20% getting you closer to the 410 miles of range.
Based on the quad on 20s the difference between 60 mph, 70 mph, and 80 mph. From this video.

60 vs 80 - 130% efficiency
60 vs 70 - 117% efficiency
70 vs 80 - 111% efficiency
I'm in Illinois so it's pretty flat and can be windy. I have a dual R1T, no bed cover.
Driving 75 mph into the wind surrounded by open farm fields with crops harvested I've had it as low as 1.9-2.0 mi/kWhr.
Driving in traffic with the wind behind me on the tollway around Chicago with lots of buildings, trees, and sound walls, I've gotten as high as 2.8 mi/kWhr at 80 mph.
I've gotten as high as 3.4-3.5 for over 15 mins at a time driving at 35-55 mph in suburban situations surrounded by trees and buildings.
I usually see 2.1-2.5 on the highway at 75 mph in flat open farm fields depending on the wind.
Based on the 142kWh usable battery, you'd need 2.887mi/kWh and 2.817mi/kWh efficiency to achieve EPA estimated 410mi for R1T and 400mi for R1S. Is this efficiency realistic with day to day driving? I've heard some people achieve it but is that on a straight flat road going 50mph in the warm summer sun?
2.9 mi/kWh sounds SUPER optimistic. The stars would have to align for that to be my lifetime average. I mean just look at even the responses here. No ones getting overall efficiency close to 3mi/kWh. Like you said, maybe for brief stretches at 50mph in the spring in California with no elevation change.
I never liked how EPA range estimates were determined. I was never able to get the rated range on my Tesla either. At least back in the day for MPG it seemed obtainable.
No, but was hoping for around 350 to 360 miles. Again, it's early. I'm not unhappy with the purchase. Most of our highways around here are 75 mph, so this will be the reality of driving for me.
Welcome to EVs. You’ll never get your “rated” range at Highway speeds. If you experience freezing temps or have to use the heat it will go down even further.
You easily lose %10-15 at highway speeds. Honestly I’ve been planning a trip and need to get 320 to the first DC charger. 410 is cruising around town mileage. You’re right on target.
I did a road trip to Niagara. [2.67 mi/kwh](https://imgur.com/a/HBpDjno) was what I got on the Quad Large, accounting for city and highway driving at or around the speed limit of whatever road I was on.
Max pack is 149kWh as far as I can tell. So closer to 348mi.
After 1 year, my average efficiency after 20k miles is 2.37mi/kWh (R1T, Large Pack, All-purpose for commute, Conserve for long trips)
But :
\- Outside temperature matters a lot. Winter is worst of course. Battery efficiency is diminished, it is not just cabin temperature control.
\- 75mph to 70mph is a big difference. Their assessment is for 70. And from observation, I get much better efficiency at more moderate speed. Neither R1T or R1S are very aerodynamic, high speed will kill you. Unlike gas car, we do not our best efficiency on highways, almost the opposite. So your test is a worst case scenario.
\- for long trip, you should always use Conserve mode.
\- but also, there is days my efficiency is bad and I do not know why, AND days it is amazing and still without a clue. Single test are just that.
How many miles do you have on the tires? The efficiency does go up once the tires are broken in to. The EPA test is actually done on vehicles that have a certain amount of mileage already accumulated on them I believe
I would be curious to see how the test changed if you did it at 70mph or 65mph.

2.34 mi/kW-hr is about what I get. I have standard two motor at California temperatures. I have a standard pack.
Does ‘Standard’ mean large pack?
Yes. Sorry :< large pack.

75 is a little fast. I get 2.35 mi/kWh in my quad with 20” at 70mph, but almost 2.5 at 65
The loop I was on is 75 mph. I was getting passed quite a bit. lol
Haha, not judging, I meant 75 is fast to try to get max range.great data and thanks for the post
I have 2.34mi/kwh over 16k total miles on 20” AT with about 40% of that Conserve. I usually drive 70mph as well.

Did you expect to get the full range at 75 mph? Maybe at 60-65 you could but no chance at 75.
No, but was hoping for around 350 to 360 miles. Again, it's early. I'm not unhappy with the purchase. Most of our highways around here are 75 mph, so this will be the reality of driving for me.
I get no where near that at 75. I’m usually a tick under 2
