About Fuel Economy
Fuel economy measures how efficiently a vehicle uses fuel. Higher MPG and km/L values mean better efficiency; lower L/100km means less fuel consumed per distance.
Note: US and UK gallons differ — 1 UK gallon = 1.20095 US gallons, so UK MPG is always higher than US MPG for the same vehicle.
Pro Tips
The MPG and L/100km relationship is inverse — better fuel economy means higher MPG but lower L/100km.
An average car gets around 30 MPG (US) ≈ 7.8 L/100km — use this as a benchmark for comparisons.
