With an overall Carivo score of 7.5/10, the 2015 Audi S4 earns a Recommended rating among the sedans we've scored. Its strongest dimension is Technology at 8.4/10, while Reliability at 6.4/10 is where it trails the competition most noticeably. It's a solid all-rounder that delivers across most dimensions without obvious deal-breakers.
Reliability and safety are the two dimensions that matter most for long-term ownership costs. We rate reliability at 6.4/10 — below the segment average in our scoring. Budget for potentially higher maintenance costs and check the recall record below before buying. On safety it earns 8.2/10: respectable, if not class-leading — several competitors bundle more driver-assist tech as standard. Check your trim's official ratings at nhtsa.gov.
The 8.3/10 performance score reflects a chassis and powertrain that punch above the segment norm — this is a sedan you choose partly for the drive itself. Technology scores 8.4/10 — one of the stronger tech packages in the segment. Expect a responsive infotainment system, broad smartphone integration, and a solid suite of driver-assistance features.
Priced from $39,128–$48,590, 16 MPG, seating 5, the Audi S4 sits in the mid-market bracket of the sedan segment. The value score of 6.5/10 is a red flag — comparable alternatives offer meaningfully more for the same outlay. Shop the segment before deciding. At 11 years old, resale value, parts availability, and whether a successor model has improved on its weak points are all worth investigating before committing.
Bottom line: Think of the 2015 Audi S4 as the dependable pick rather than the exciting one. Its softer scores in value and reliability are the only real asterisks. Shoppers who value predictability over headlines will be well served.
