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).
About Miles per US Gallon
Miles per US gallon (mpg(US)) is the US and Canadian standard, displayed on every EPA Monroney sticker and used in CAFE regulations. The US gallon = 3.785411784 L; 1 mile = 1.609344 km. 2026 CAFE passenger car standard: ~49 mpg. Toyota Prius Prime: 52 mpg; Tesla Model 3: 132 MPGe. Historical: Ford Model T 21-25 mpg; 1973 US full-size cars 10-15 mpg. NASCAR at race speed: 4-5 mpg; Class 8 semi: 5-8 mpg. L/100km = 235.21458/mpg(US): 30 mpg = 7.84 L/100km; 50 mpg = 4.71 L/100km.
