The only recent car I remember consistently beating advertised estimates is the Jetta TDI, if I remember correctly it's rated at around 43 MPG highway and journalists routinely see significantly better mileage, nearer 50 MPG.

All that said, I will shoot myself in the foot if you can prove to me you got 47 MPG in a Fusion hybrid. Short of extreme hyper miling techniques, that number has always sounded like utter bullshit to me and I'm not a bit surprised Ford is taking heat over this, and I really expect these advertised numbers to be revised shortly.

Do you guys really think Ford has the ability to produce a cheap midsize sedan that can get near that mileage claim?
The EPA does test cars and confirm results, maybe not for every single car, but they do monitor the results, and most O.E. vehicle manufactures don't cheat for the precise reason that by self policing they generally avoid the issues that Hyundai faced.

Given how the previous Fusion hybrid was capable of close to if not over 42 mpg city and the new one has a better powertrain it should do better at least in the city, and aero tweaks to help the highway test result.

I can't confirm the results, but the test is done on a dynomometer, and if it can run as extensively and as quickly on electric only propulsion it can get much higher mpg ratings on the test than is easily achieved in the real world with a lead footed driver.
