I've had my 7.5 Performance DSG 4 months now and covered 10,500 miles. This is my 5th GTI in 20 years so am pretty used to the fuel consumption expectations.
However, the results of this new 7 speed DSG box that delivers 2,000RPM at 80MPH on a motorway are pretty impressive :
Total miles : 10,440
Average miles/month : 2610
Average MPG over this period : 38.2
Gotta be happy with that.
