| 2013 Audi A4 / S4 Seat Room and Comfort: Pros | ||
| Year | Body/Powertrain | Comment |
| 2012 | 4dr Sedan supercharged 333hp 3.0L V6 7-speed automated manual AWD |
Without question, the most comfortable car for long road trips that I've ever owned. Our family of four took a road trip of ~2000 miles, longest single-day drive was 11 hours, and never felt any fatigue or discomfort from the seating. Seats are firm and supportive but not harsh or uncomfortable. see full Audi A4 / S4 review |
