If you're thinking about a new midsize 4 door car ... be sure to test drive the new Volkswagen Passat TDI.

Our mileage has been pretty remarkable -- so far we're averaging just shy of 46 MPG, with a one-day high of 50.2 MPG (moderate speeds and only a few steep hills to climb) and a low of 42.6 MPG (low speeds, lots of hills). Based on what I've seen, I have no doubt that we could top 55 MPG on a long, level road with a 65 MPH speed limit...
