What is l/100km

L/100km (litres per 100 kilometres) is a measurement of fuel efficiency. It tells you how much fuel a car needs to travel 100 kilometres.

The lower the number, the more fuel-efficient the car is. So, if a car has an l/100km rating of 6.5, it means it uses 6.5 litres of fuel to travel 100 km.
