With my Brabus, the mpg is directly proportional to the amount of fun I am having
On the Autobahn…
Translated to ‘English’ …
Total Distance: 353 km = 220.6 miles
Average Speed: 152 km/h = 95 mph
Fuel Consumption: 20.3 l/100km = 13.9 mpg
At the other end of the scale, I once drove all the way from Leeds in the UK back home to Germany at a much more sedate 100 km/h (about 60 mph) and averaged 6.6 l/100km (42.8 mpg).
Average around town is usually less than 8 l/100km (over 35 mpg).
