The Audi A7 arrived on the scene a few years prior, and it instantly added a fresh look into the Quattro-loving lineup. I’m not going to call it a four-door coupe, because that’s a stupid thing to call a car with four doors. Still, the A7 wears a shape that’s far better looking than your standard sedan. It’s a trend that was started with the original Mercedes-Benz CLS, but I think Audi perfected it when it launched the A7. Now, the Audi A7 family has expanded. The standard car is joined by the fun S7 and the cuckoo bananas RS7. There’s another one out there, however, that’s a bit more reserved. It’s the 2014 Audi A7 TDI… and it might wind up being your favorite member of the Sportback family.

We never needed to put more fuel in it, because it barely drinks the stuff.]
