my guess would be 28.5 mpg if it's the 4 cylinder model. but if it's the v6 i'd guess around 26.7 mpg? but that's guessing if u don't have a heavy foot like most pple who have the tdi model. i had one a few yrs ago and i did have a heavy ass foot. but nowadays that gas is so freakin hi, i just tap that pedal, and pray for no hills
