Only through about 1/2 a tank right now and haven't confirmed mpg via old fashioned hand calculations...But, it looks like this 6 speed manual Passat is going to crush the TDI DSG Golf in fuel efficiency, at this point based solely on the MFD and computers reporting on approx mileage to empty I'm averaging 45+mpg in combined driving, if the MFD is accurate the Passat is amazing on the highway, I think with a little care I could hit 50 mpg driving 65-70mph, matter of fact I've been averaging 47-48mpg on my daily commute which includes city/stop and go/bumper to bumper/highway cruising at 65-70+ when possible, and break-in driving. I know this route very well and I'm seeing 5-10 mpg+ with the Passat on certain highway stretches.The MFD on my Golf was always dead-on accurate so I'm hoping this one is too. This car is a highway machine, there is no way you could only get 43mpg like the EPA states, heck it will get 43mpg going up a slight grade at 70mph
