What is the Wh/mile number to achieve Rated Range on an X?

With my P90D, 22 inch rims, it is 320-325. Usually achieved on Hyw with ~ 65mph driving in Cruise Control. That is based on my experience where the rated and actual (last 30 miles) equal the same.

That's really great for a P90D with 22 inch rims. Most 90D with 20 inch rims would like to see that.

Keep in mind that Tesla also estimates a 10-15% range decrease with 22" wheels

On my X75D, rated is somewhere very close to 310 Wh/mile.

My lifetime is running about 316 right now (~3000 miles), so it's realistic for me in decent weather at least.

My 90D over 7000 miles my lifetime is 340 Wh/mile. When we go on long road trips I tend to get better. We did a 600 mile road trip to the mountains and back and my average for that whole trip was 318 over the 600 miles. This is with a 90D with 20" tires. I usually do 65-70 with autopilot on the highways. Most speed limits here at 65-70.
