Like Mercedes, Audi is putting stock in diesel for North America. With that they have unveiled two flavors of the Q7 TDI. For those who just need a nice luxo-SUV with good mileage the 3.0L TDI is for you. However, for those of you who know a vehicle isn’t about just getting from point A to point B, then make sure you add another 6 cylinders after that.

Mercedes wants consumers to know they can still have the large. powerful cars Americans expect and still get good mileage.
