"Liters Per 100 Kilometers" (L/100 km) is a common measurement used to express fuel efficiency in vehicles. It indicates how many liters of fuel a car consumes to travel 100 kilometers. A lower L/100 km value means better fuel efficiency, as the vehicle uses less fuel for the same distance. This metric is particularly useful for comparing the fuel consumption of different vehicles, including cars, trucks, and motorcycles. It helps consumers make informed decisions when purchasing a vehicle, as more fuel-efficient options can lead to cost savings and reduced environmental impact over time.
