Calculate Fuel Consumption Drag Coefficient Speed and Weight

von 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“

Calculate your air resistance depending on the speed
What is my speed

What is my CW value (truck 8 or 0.8)

Your resistance increases quadratically with the speed see see Wikipedia to

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.
