The fuel economy of a vehicle is a measure of how much fuel its engine uses over a certain distance, most often 100km.
What impacts fuel economy?
The listed fuel economy is an average based on a daily use which is affected by road, traffic and weather conditions, and vehicle speed and load. Driver behaviour also affects fuel economy too as manoeuvres such as sudden acceleration and heavy braking waste fuel.
How it is calculated?
The following formula is used to calculate fuel consumption in
litres every 100km.
- Fill up your car’s tank.
- Record your current mileage as displayed on your odometer. If your car has a trip odometer, reset it to zero.
- Drive your car normally until you must fill up again.
- Use your odometer to see how many kilometres you have travelled since your last filled up and record how much fuel was used during that time.
If you don’t have a trip odometer, write down the latest odometer reading and subtract the first odometer reading to determine how far you have driven.
- Multiply the amount of fuel used by 100 and divide that by the total kilometres driven. For example: 42 litres times 100 divided by 400 = 10,5 litres/100km.
