Hello here,
i have some question....
I had a look at the way i take every day to go to work.
It is around 17 Km long (10.5 Miles), and max speed is 80 km/h ( 50 Mph).
The positive height difference is 160m and negative 91m.
The main thing to have a look concerning the car, is the weight before the aero (In France, it is called "Cx" for the drag coefficient , and "SCx" for the area drag), right?
On a such short distance, a difference between a Cx of 0.28 and 0.31 is not very important.
But, a difference between a weight of 640 Kg (Citroën Ax - 1410 lbs) and my convertible with 1410Kg (3110 lbs) is more imprtant.
The problem is, if i want a light car, the engine is light, and need to shiftdown in uphill....
