L/100km Tips

Liters per 100 kilometers (L/100km) is the standard fuel consumption measure in most European, Asian, South American, and Australian countries.
Lower L/100km values indicate better fuel efficiency (less fuel used per distance).
To convert from L/100km to km/L, divide 100 by the L/100km value.
To convert from L/100km to MPG (US), divide 235.214 by the L/100km value.
The average modern sedan has a fuel consumption of about 7-9 L/100km, while smaller cars often achieve 5-6 L/100km.
For every 1 L/100km reduction in fuel consumption, a vehicle driving 20,000 km annually would save 200 liters of fuel.
