| 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 | ||

Smaller than the Maxima. Third person would be uncomfortable, less knee room. The plastic trough behind the front seat is too low. see full Infiniti G review |

The rear seat is basically a storage area. No one can sit back there! But its really no different than the rear of any convertible. (like my Mercedes Benz CLK350) see full Infiniti G review |

Seats in back are cramped. Once the kids hit teenage years they are not going to be happy back there for long rides. see full Infiniti G review |

Seems smaller than the G35, no rear reclining seats anymore and the headrests stick up a bit more than the old car. see full Infiniti G review |
