2017 Cadillac ATS Seat Room and Comfort: Cons
Year	Comment
	Unfortunately, the "why nots" from three years ago remain. The compact Cadillac sedan's rear seat hasn't gotten any larger, and the coupe's is even tighter. Meanwhile, Audi, Lexus, and Mercedes have introduced competitors with roomier rear seats. At 5-9 I can sit behind myself with a little room to spare in the ATS sedan, and virtually none to spare in the ATS coupe. Drivers who need the seat further back than I do will eliminate leg room for all but the shortest rear passengers. see full Cadillac ATS review
