About Liters per 100 Kilometers
Liters per 100 kilometers (L/100km) is the standard fuel consumption unit of the EU, China, Australia, and most of the world. Lower values mean greater efficiency: 5 L/100km is exactly twice as efficient as 10 L/100km. EU WLTP certification requires reporting in L/100km; CO₂ in g/km ≈ L/100km × 23.9 (petrol) or × 26.5 (diesel). Benchmarks: European average new car (2024 WLTP) ~6.5 L/100km; compact SUV 8-11; articulated truck 28-35; M1 Abrams tank ~130. 1 L/100km = 235.215/mpg(US) = 282.481/mpg(Imp).
