I recently got 27.1 mpg (per the trip computer) in my S on a recent trip. I was trying to see if I could get good mpg, so that’s using Eco mode, Adaptive Cruise, and being light on the go pedal. I was running the A/C, cooled seats, and radio the whole time on my 2 hr, mostly highway, trip. I was pretty amazed.
That’s FAR from my usual 18 mpg on my stop and go commute to work and to drop my daughter off at school. I also have a bit of a heavy foot like AHinCO. 🚘
My overall average is 33.79 miler per gallon (66'6674 total miles driven; 1'973.166 gallons of fuel purchased).
37.20 MPG is the best fuel mileage between I averaged between two fillups (516 miles on 13.871 gallons).
541 miles is the most I drove between two fillups. It was not intentional - I miscalculated, and I drove the last half mile to the filling station with 0 Mile to Empty on the dash, and I hoped the car would not die in the middle of the intersection. I put back in 14.966 gallons at the pump.
