Model 3 SR+, built April, 2019. Driving flat roads from Illinois to Indiana, 40º F, cabin temp @ 68º F, no significant wind, no traffic, driving 55- 70mph. Used 150 miles of range to go 105 miles. Does that seem normal? This is pretty much how it goes all the time. These weren't ideal conditions, but it's not much better even in the best circumstances.
