I have an interesting datapoint on doing the same ~125 mile drive at about the same time, within two minutes of the same drive duration, in successive weeks with significantly different ambient temps. Total drive duration: 1:55 Distance: 124miCabin temperature: 74 Wheels/tires: 19" with Goodyear Eagle Tesla-foarm Touring, approx 20K miles. I set AP to 75mph continuously with some places where I boosted it 5mph to overtake the right lane and move over for advancing traffic behind me. Mild freeway traffic overall. Last week: temps in low 60s during drive Today: temps 85-90 Before both drives, car was range charged to 249mi. Range mode on. Rated range after drive: Last week: 118mi Today: 131 mile So with temps in between 60-70, the range for a 124 mile drive dropped from 249 to 118 (131 miles equivalent). Today, the same drive utilize 118 miles, or 6 miles less than the actual distance, despite driving at 75mph most of the while with A/C on. Very nice indeed. I expected more residual range due to higher ambient temps, but not more than a dozen miles more.
