Here is a real-life example comparing flying and driving to the same
place. The plane is an RV-6A, O-360 carbureted, one Lightspeed ignition
some drag from old wheelpants and one crooked main gear fairing.
Car is a 2001 Jeep Grand Cherokee Laredo, cruise control, 8 Cylinder
and automatic with full time 4WD.
Flight to Page took three hours (headwind) at 16,500 feet. Distance
about 400 statute miles using 19.5 gallons of 100LL. The comes to
20.5 miles/gallon (6.5 GPH). Add one hour for additional time before
and after the flight and the trip took four hours. As an aside, the trip
back took 2.5 hours and burned 14.9 gallons for 26.8 MPG (6 gallons/hr).
The trip back was at 17,500 feet and I had about a 30 knot tailwind.
The car trip took 12 hours each way. 600 miles at 21 MPG burned
about 28.6 gallons each way.
The plane trip was done in one day whereas the car trip took over two
days and required two nights in a hotel.
Pictures for perusal included.
