Drove from MN to Daytona Beach area and back in early July 1553 miles each way plus 600 miles driving around. I drove hard 90% of the time 80 mph + 125 mph at one point for a couple of miles. Averaged 21.5 mpg confirmed via receipts using 91 to 93 octane. I used normal,eco modes 80% and sport the other 20%, 3 adults with 800 lbs of stuff that mpg dam happy with that and still outrun just about anything.
