Fuel consumption: l/100 km, mpg US and mpg imp
Europe states consumption in litres per 100 kilometres, English-speaking countries in miles per gallon. The two are inverse to each other: a lower figure in l/100 km corresponds to a higher figure in mpg.
| l/100 km | mpg US | mpg imp |
|---|---|---|
| 3 | 78.404861 mpg US | 94.160312 mpg imp |
| 4 | 58.80364575 mpg US | 70.620234 mpg imp |
| 5 | 47.0429166 mpg US | 56.4961872 mpg imp |
| 6 | 39.2024305 mpg US | 47.080156 mpg imp |
| 7 | 33.60208329 mpg US | 40.35441943 mpg imp |
| 8 | 29.40182288 mpg US | 35.310117 mpg imp |
| 10 | 23.5214583 mpg US | 28.2480936 mpg imp |
| 12 | 19.60121525 mpg US | 23.540078 mpg imp |
| 15 | 15.6809722 mpg US | 18.8320624 mpg imp |
The US and imperial gallons differ: 1 US gal = 3.785411784 l and 1 imp gal = 4.54609 l, so mpg imp is always higher than mpg US for the same consumption. The conversion is normalised through litres per 100 kilometres because the two scales run in opposite directions.
