I don’t know Jerry, I have a 2013 M37 (not the sport so mine should get better MPG) I have never got 21MPG even on the hwy. and you got 21 “overall”..wow. The transmission is the “learning” type, it is supposed to “remember” how you drive and shift accordingly. Both me and my wife drive the car (not that much difference in driving style) but when you leave a stop, going up a hill, the tranny seems to not be able to make up it’s mind what it wants to do….for $60K, I am disappointed.
Sorry to hear this James, I really like the car. You might have your dealer look at it and see if some adjustments can be made. I test cars in Dallas where everything is flat, and that might make a difference too.
GOOD LUCK, I hope the mileage improves.
