My wife's 5mi commute usually takes 25-35minutes with traffic. thats a lot of heating the battery and cabin for such little mileage. hence horrific commute efficiency. I bet OPs commute is similar. As far as long trips with the Mach-e it has been much much more efficient.Strange result. Plugging your data into ABRP, which uses real-world data for its predictions, shows your car, a 2021 Performance with 20" tires, would do that trip at 284Wh/mile. Yes, ABRP is using the 27F temps, 67F interior, and speeds the OP specified, 68mph max, etc. 34min trip, 31 miles, 13% SOC used, 9.1kWh, 284Wh/mile.
Are your brakes dragging? And, what app are you using?
