I have had a 2013 Yeti diesel 4x4 170bhp dsg pre-facelift L&K model for a couple months now, bought to be ready for winter weather which in years past saw me get cut off in my Warwickshire village. Initially I was very concerned about the terrible fuel economy I seemed to be getting, mostly in the mid thirties mpg and somehow showing an average consumption of below thirty, despite doing very little city driving... for my winter preparation I swapped the fancy 17” alloys that came with the car (with some average Dunlop tyres fitted) for some Skoda Spectrum 16” alloy wheels with a new set of Nokian WR A4s. Almost immediately my range on a tankful of diesel went up by over hundred miles. Since then I have been obtaining even more spectacular fuel economy by using cruise control at 30, 40, 50 and 60 mph (have not done motorway driving since cc experiments started) - it seems counterintuitive but the best economy with cruise control comes in S mode on the DSG when the dashboard displays S6 selected even at speeds as low as 45 mph, and even on quite hilly rural roads...
