What was your average MPH when the MPG read 29.5? Lot of hills or flat?
BTW, I've never seen trip averages of 29.5 mpg with my M2C or my previous M235i, but I live in CT where nothing is flat. Oddly, I have never set the cruise at 85 either - it's 70 for me, and I still can't get the kind of mileage you got. Who knew the S58 was more efficient than the N55 or S55?

Other notes: automatic & tires were at 36 psi (a little higher than the recommended 32 on the door sticker).
Fairly flat from Austin to Dallas. I don't have My Trips activated, so I don't know the avg mph. I got stuck in 3 separate stop & go periods for several miles each during the trip. Probably a good 5 mi each time. I also had a good chunk of time over 90 mph (making up those stop & go sections). Minus the S&G, I was never below 75 mph.
Speed limit is 80 or 75 for the majority of the drive & I've found if cruise is set at 85 (really 83), I don't get a second look from the LEOs.
