| 2014 Audi A8 / S8 Seat Room and Comfort: Cons | ||
| Year | Comment | |
| The A8's seats can be adjusted just about every way its possible to adjust a seat. While they do provide proper support, they're firm and don't mold themselves to the human form, at least not mine. They are very good seats, but those in the Jaguar are better and those in the BMW are best of all, both more supportive and more luxurious. see full Audi A8 / S8 review | ||
