Calculate Fuel Consumption Drag Coefficient Speed and Weight

You want to know how high your fuel consumption is depending on the speed of your vehicle? It increases exponentially … Compare eg: 80 km / h with 160 km / h from 8000 to 32000 it is a quadruple. Or in other words, you can save 75% if you drive at half the speed! Maybe you’re listening to an Audiobook or talking to a passenger from the commuter ride-sharing community.

“A van with 60 km / h consumes significantly less fuel than the most aerodynamic vehicle with 120 km / h”

Resistance of motor vehicles, the dependence on the Reynolds number can often be neglected. Then, the CW value is set as a constant value so that the resistance increases quadratically with the speed.
