TrueDelta Reviews the Seat Room and Comfort of the 2014 BMW 6-Series Gran Coupe

2014 BMW 6-Series Gran Coupe Seat Room and Comfort: Pros
YearComment
2014 Like all BMWs midsize and larger, the 6-Series Gran Coupe can be equipped with the make's multi-contour seats. Thanks to abundant padding and a large number of adjustments, these are about as comfortable and as supportive as seats get. The Audi A7's seats, firmer, flatter, and with far fewer adjustments, aren't as luxurious or nearly as supportive in hard turns. (I did drive the car for over nine hours one day without even a hint of soreness, though.) see full BMW 6-Series Gran Coupe review
2014 BMW 6-Series Gran Coupe Seat Room and Comfort: Cons
YearComment
Even with the 4.5-inch wheelbase stretch, the 6-Series Gran Coupe has a tight, low-mounted rear seat with a virtually useless center position, as the center console extends all the way to the seat. At 5-9, I can sit behind myself with an inch or so above my head and a couple ahead of my up-angled knees. The cushion is well-shaped, but under-sized. The A7 has a much roomier, more comfortable rear seat. It's the one to buy if you want adult-sized people to use that second pair of doors. (Why you'd want these doors if you're not going to use them? I don't know--ask the person who owns one.) see full BMW 6-Series Gran Coupe review
