Had a real good run in the GTD yesterday (first time in a long while), down to Lichfield. Took it stead on the M6 (65-70ish) and then 50mph through the road works (average speed cameras), then 60ish down the A50 and other A roads to Lichfield, and was pretty chuffed to see these figures on my return. This was from a cold start, on quite a busy M6.
Car set to individual mode on the driver profile select - which for me is Engine - Normal, DCC - Comfort, ACC - Sport
So 161mile round trip at an average speed of 48mph and it returned an indicated 64.5mpg (which knowing my computers accuracy) should work out at about 61-62mpg. Pretty chuffed with that on a DSG box. It had my theoretical indicated range as 659 miles which I've never had before (415 range plus 244 miles travelled).
Still not quite the 68.9mpg Extra Urban that VW quote (based upon a real 62mpg it's still 10% out), but pretty much in line with the advertised Combined figure of 60.1mpg for my model.
