I have a 2019 premium manual, 38,000 miles on the odo. We live at 5100 feet altitude. We get 25.5-26.5 on the, as Lonelydriver so eloquently put it, exaggerometer. We also take a once a week trip to our other house (260 miles round trip) in the lowlands (700 ft) and get about 31.5 MPG with the majority of the trip at 75+ on the interstate.
