Fuel Efficiency-Light Plane Vs Small Car
I'd like to know in general terms how a modern lightplane like a Cessna 172, compares to a modern smallish car in fuel efficiency both travelling in calm air and level flight at, say 90mph. I have read about specialized composite magterials aircraft getting 50mpg.

No comparison! I own a Hyundai Accent, 30 MPG, holds 11 gallons, will get 350 miles per tankful at 65 mph.
I fly a 1965 Piper Cherokee 180hp that gets 10 Gallons per hour. It holds 50 gallons total, will go 350 to 400 miles per tankfuls. (two tanks, one in each wing). I flew last week four one hour. It cost $65.00 to top off the tank.
Plane is twice as fast as the car, four-five times more expensive!
I won't discuss the other expenses in aircraft ownership except the plane spends most of its time on the ground costing $!

Have to look at things a little different.
The Airplane saves some time, and may save gas depending on the route. If you can fly for an hour and get to the destination, or drive for 3 in traffic, the plane might well be more efficient.
What is the real fuel cost to the destination?

lets say you want to go 300 miles.
In a car averaging 60mph and 30mpg = 5 hours and 10 gallons of gas ($40 of gas) $4/gal
In an aircraft average 120mph and 10gph = 2.5 hours and 25 gallons of gas ($125 for gas) $5/gal
However all kinds of variables can be thrown into these calculations including weather conditions, wind, maintenance and insurance costs, and even parking or hangar costs. The figures I used are just rough estimates for aircraft fuel burn and speed.
If you want to fly, buying a commercial ticket would be cheaper, but the car is the most efficient.
Some small light sport aircraft i.e. zenith zodiac, sonex, sonerai, vans aircraft, can average 30mpg at 4 gph, but not all the time.
