Hi, I just recently went from a 2015 Leon FR 2.0 TDI 150 to a 2018 1.8 tsi FR ST dsg. In my old Leon I was averaging 40+ mpg around town and 50/60+ country & Motorway driving, my new ST struggles to hit 30 mpg around town, and that's with me driving like a saint. The ST is obviously heavier then...
