TrueDelta Reviews the Seat Room and Comfort of the 2017 Audi A3 / S3 / RS3

2017 Audi A3 / S3 / RS3 Seat Room and Comfort: Cons
YearComment
Same goes for rear seat room. The Audi S3's rear seat can be a tight fit for adults, especially if those in the front seats are tall. But at least most adults will fit. My adult-sized children rode in the back seat from Detroit to Nashville and back without complaining about the amount of space. (It helped that none of us are tall; I'm 5-9.) The back seat in the CLA provides far less room for heads and legs. Mercedes markets it as a coupe for a reason. see full Audi A3 / S3 / RS3 review
