Pros: Availability of refined diesel model; impeccable interior materials; fine all-around build quality; quick acceleration with supercharged V6
Cons: Some complicated controls; prices escalate quickly as options are added; rear seat not as spacious as exterior size would suggest
CG Says: The Audi A6 excels for its high levels of polish and sophistication that strikes a nice blend between the performance-oriented BMW 5-Series and coddling Mercedes-Benz E-Class. First-rate interior accommodations and a remarkably hushed cabin add to the experience. We also applaud the addition of the new-for-2014 TDI diesel model. However, rear-seat room is less than impressive, and reasonable base prices quickly skyrocket as you add expensive standalone and packaged options. Unfortunately, some of the more desirable luxury and convenience items will force you into the high-end 3.0T model. Still, for those with the means to acquire such a vehicle, the A6 is an extremely appealing premium-midsize sedan.
