I just ran a test to see what energy efficiency my Model X achieves at 65mph (to get more accurate estimates from abetterrouteplanner.com). I love the results, but they seem significantly different from what others have reported. Can someone with more experience weigh in on whether these results are reasonable? If not, where did I go wrong in the testing? I drove 11 miles at 65mph, 5.5 miles each way to minimize the impact of elevation changes. Round trip: 286 wh/mi. First leg: 394 wh/mi Second leg: 177 wh/mi Obviously, there is an elevation difference, thus the roundtrip measurement. Test conditions: 20" tires, TACC and Lane Assist on, 60F outside temp, music and AC on, light breeze, light traffic (car never slowed from 65) well paved and mostly straight highway. I measured once I was at 65mph and stopped the measurement before decelerating, this was to minimize the impact of starting and stopping a trip on such a short distance measurement. I am interested in the measurement for a cross country trip that will be entirely highway and happen this week, so I think the conditions are applicable.
