Fuel Consumption (l/100 Km, Mpg)
Fuel consumption shows how much fuel a car uses for a given distance, for example in litres per 100 km or miles per gallon.
What is Fuel Consumption (l/100 Km, Mpg)?
Lower litres per 100 km and higher mpg both mean better efficiency. Official figures come from standard test cycles; real consumption depends on driving style, traffic, weather and load. Electric cars use kWh per 100 km in the same way.
How it works
The trip computer calculates consumption from the injected fuel quantity and distance travelled.
Why it matters for your car
A sudden rise in consumption can point to low tyre pressure, a dragging brake, a faulty thermostat or a sensor problem. Measuring at the pump over several fill-ups is more accurate than a single trip computer reading.
