RC:
Fuel consumption is out of this world, during my testdrive (and I didn't drive over 180 kph because of the snowy road conditions over here in Bavaria), the X6 M ate 21.7 liters / 100 km. Not much different to my Cayenne Turbo S under similar conditions/speeds I'm afraid but I also have to emphasize that I was driving in M-Dynamic Mode most of the time.
This will decrease by 2-3 litres after you put 10K km on the odometer.
