6-speed shiftable automatic AWD		 Huh, never have, never will sit in the back of this car...It is a hoot to drive see full Audi A4 / S4 review
2008 4dr Sedan 420-horsepower 4.2L V8
6-speed manual AWD		 Rear seats seem very cramped for leg room. I've never used them, but have only ever dared to take adults on short trips in the back. Heated seats are available for the rear passengers. see full Audi A4 / S4 review
2008 4dr Sedan 340-horsepower 4.2L V8
6-speed manual AWD		 Depending on how tall your front passengers are, your rear passengers may not have any room to sit. Can fit 4 average sized adults, but it will be tight. see full Audi A4 / S4 review
2008 4dr Wagon turbocharged 200hp 2.0L I4
6-speed shiftable automatic AWD		 Seats hard and unforgiving,had a sore back in first hour. Saab seats always been superb. see full Audi A4 / S4 review
2008 4dr Wagon turbocharged 200hp 2.0L I4
6-speed shiftable automatic AWD		 The rear seat is adequate, but not large. Child seat fits fine, but my son can kick the back of the front seat. see full Audi A4 / S4 review
2008 4dr Sedan 255-horsepower 3.1L V6
6-speed shiftable automatic AWD		 The rear seat is too small for adults on long trips (over an hour). And the rear seat can only hold 2 people even for short trips. see full Audi A4 / S4 review
