TrueDelta Reviews the Seat Room and Comfort of the 2016 Audi A4 / S4

2016 Audi A4 / S4 Seat Room and Comfort: Pros
YearComment
2017 Before the 2009 model year redesign, the Audi A4's back seat was too tight for adults of more than average size, and marginal even for these. With the 2017 the back seat has grown yet again. Not only this, but the cushion is higher off the floor than in previous A4s or in competitors, such that it's now the most comfortable in the class. This said, the rear doors could open more widely, such that I struggled to get a decent photo of the rear seat. Since its 2014 model year redesign the Lexus IS has had a passably roomy rear seat, but it can't match the Audi's for comfort. see full Audi A4 / S4 review
2016 Audi A4 / S4 Seat Room and Comfort: Cons
YearComment
Pressed to come up with another con, I might offer the front seats. There's nothing bad about them. There's just nothing outstanding about them, either. Those in the sport-trim Lexus provide more lateral support and feel more comfortable to me. (With seats personal impressions are bound to vary, so definitely evaluate them yourself.) see full Audi A4 / S4 review
