Today's run was from Bentonville, AR to Albuquerque, NM. Cruised at 70 mph. Had a head wind of about 35 mph almost the entire day and a run from 1000ft to 5600ft overall including a stretch over 7000 ft. and even so got 27.1 mpg for the day's effort. For the trip so far: 2560 miles, 83.32 gallons for 30.72 mpg overall average.
One final leg tomorrow of 800 miles.
Couldn't be happier with the way the car performs.
