I hit a new low last night with a 79 mile trip out to dinner. -2 to 3F, an average speed of 45 MPH, 3 people, dry salted roads. We started with 80% battery, not preconditioned, cold interior, returned home with 23% battery.
39.2 miles to and from. So, 0.57*88=50.2 kWh to drive 78.4 miles is 1.56 mi/kWh or an overall range of 138 miles, premium AWD ER. Overall range loss of 51% in these conditions. Heat on Auto 72, 2 seats and wheel. Cruise used.
Car reported 1.55 (1.2 to and 1.9 return) meaning reporting error was minimal. Also the travel time shown on the final screen screen is wrong. IDK what went wrong with Trips. We did not drive 70 MPH. For a strange reason the miles of the “trip” did not reset coming back and were spot on at 78.4 for the round trip. The time is about right and return Mi/kWh.
I think I could assume if I preheated we would have done 1.9 mi/kWh each way, a much better outcome, 167 miles range.
With an SR, that’s a range of 105 miles.
Even funnier, look at my EV driving data from FordPass, I just found it recorded. 2.1 on the way there (1.2 actual) and the return with double the miles, 2.4 (1.9 actual)., 100% incorrect and attached below. I will have to say this data is useless.
