On the highway would be 9.6 l/100km at 170km/h a very good efficiency, but I roll here in the 1. gear in a traffic jam. 9.6 l/100km for 9km/h. Makes about 5.3% efficiency.


  Efficiency car and mobility


What is the real efficiency of our mobility with cars? Enlightenment about a lot of misunderstoods about the efficiency of engines and the production of fuel.

Ideal drive for cars
For an ideal drive system with 100% efficiency, only air resistance and rolling resistance has to be calculated
