With my 116i the average consumption is 6,1l per 100k, only 3700k done so far. Mostly on comfort, but very much enjoying the sportmode from time to time
We went to Austria in july, up in the mountains and through Germany (so speeds up to 190kmh, usually 140-150) and my average was only 6,2 (1600k trip).
Very, very pleased with my figures!
