So what gives? I saw the Golf TDI got more mileage and then the Jetta too for 2010. I've also seen a different DSG mentioned, that doesn't seem likely for 1 year unless they are carrying this engine/transmission for a few years in the Golf.
Today was the first day of my commute with my 2010 TDI (manual), and I got 51 MPG! My commute is 110 miles round trip...2010 TDI Sedan 6spd here.
I got 42 mpg on my first 3/4 of a tank, driving 50/50 highway back roads, did a couple 45 miles trips where the computer calculated 50mpg. Doing another 250+ miles this weekend see what it brings.
