However, the average car speed is a useful indicator of fuel consumption. So, the next time that you will have to drive for a long distance try to keep your instantaneous car speed within the range 55 – 80 km/h as much as possible, in order to minimize the fuel consumption of your car.
What is the fuel consumption of a car?
0 – 30 km/h (0 – 18.64 mph): For velocities below 30 km/h the fuel consumption is quite high (above 8 l/100km – 29.34 mpg). Unfortunately this speed range is typical for cars circulating in a city – urban environment. Cars are subjected to a continuous start and stop motion due to junctions and traffic lights.
