OK, now let's calculate what MPG I should get at a steady 55 MPH.
55 MPH = 80.7 Ft/Sec.
Drag = 0.0143 X 80.7^2 + 54 = 147 lbs.
Hp = 147 Lbs X 80.7 Ft/Sec / 550 Ft-Lbs/Hp = 21.6 Hp.
Estimated fuel consumption = 21.6 X 0.5 Lbs / Hp-Hr / 6 Lbs/Gallon = 1.8 GPH.
Estimated MPG = 55 MPH / 1.8 GPH = 30.6 MPG.
This is almost exactly what I would expect on a 17 degree day with zero wind at 55 MPH. Now, I had a good turbodiesel at 0.35 lbs / Hp-Hr, I would expect 43.7 MPG under the same conditions. DROOL.
