2015 Audi A6 / S6 Seat Room and Comfort: Pros
Year	Comment
2016	The second benefit of the Audi A6's more open and expansive interior: it feels roomier, especially in the front seats. With no "race car" or "jet fighter" pretensions, the Audi is easier and more relaxing to drive. The BMW, Cadillac, and Mercedes interiors all feel tighter and more confining. see full Audi A6 / S6 review

2015 Audi A6 / S6 Seat Room and Comfort: Cons
Year	Comment
	Want a second reason that the Audi A6 might not be your best bet? Perhaps its front seats, as these despite a four-way lumbar adjustment (driver only unless you get the 3.0T Prestige) are just okay. Though likely what a German orthopedist recommended--I've sat in these seats for ten hours without any soreness--I'd personally prefer seats that are less firm and more form-fitting. This said, forms differ, and the Audi's might fit yours better than mine. The rear seat is roomy but, like most, is mounted too close to the floor to provide adults with sufficient under-thigh support. With that, I'm pretty much out of why-nots (though I'll touch on a potential one below). A very good all-around car, the Audi A6 has no glaring faults. see full Audi A6 / S6 review

2007	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	3rd row seats are big enough and comfortable enough for an adult. 2nd row seats are the best captain chairs I have ever sat in in a car. Glass roof gives additional room appearance. see full Mercedes-Benz R-Class review
