so, if doubling your speed takes 4 times the power, roughly speaking, and power is proportional to fuel consumption, again roughly speaking, then with the right engine combo, you should be able to cruise @ 90mpg at 103mph and 180mpg at 52mph?

Would narrow wheels and direct drive, instead of wings and a propeller help or hurt mpg?
