Have seen 28mpg mid-run in my CLS63 (M156) but that's normally dropped to 26/27 by the time I've parked up on a few trips to/from Silverstone and Donington this year.
150+ miles each way makes for a reasonably long run and sometimes you get a clear run where nobody has decided to have a smash and cause carnage.
