Yes...Autobahn. Regarding the fuel consumption: believe it or not but with the M button (all settings set to Sport) and MDM active all the time, the fuel consumption is between 21 and 22 l / 100 km, no matter how fast or slow I drive. Never got the truck under 20 l / 100 km, not even during run-in. Sometimes I really wonder how people get a fuel consumption of 17 or 18 l / 100 km, this would be impossible for me.

22 l / 100 km equals to aprox. 10.7 mpg. Cheers.
