2025 Audi S5 Sportback

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2025 S5 Sportback.

Transmission Automatic (S8)

The 2025 Audi S5 Sportback arrives as the latest iteration of Audi’s five‑door coupe, retaining the brand’s S8‑type automatic gearbox and delivering an EPA rating of 20 mpg city, 29 mpg highway and a combined 23 mpg. Across the model year the vehicle has logged only nine owner complaints, with the most frequent issues reported in the electrical system, service brakes and forward‑collision‑avoidance suite, and it has been subject to two recalls. Compared with the earlier 2018‑2021 window—where complaints ranged from a high of 26 in 2018 to a low of just one in 2021—2025 sits toward the lower‑end of the reliability spectrum, indicating a continuation of the improving trend that researchers can regard as a relatively stable and dependable point in the S5’s history.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2025 Audi S5 Sportback enters the record with only 4 complaints logged, all tied to electrical system, forward collision avoidance, lane departure, service brakes, or engine areas, and no recalls, investigations, or crash/fire incidents reported. This stands in contrast to the earlier model years: 2018 and 2020 saw complaint spikes of 26 and 25 respectively, while 2019 and 2021 were lower at 6 and 1, and recalls gradually increased from 3 to 5 across the 2018–2021 span. The 2025 model’s minimal complaint count suggests a potential improvement, but the data is limited to a single year without the multi-year accumulation that earlier years have, and the upward recall trend in prior years hints at ongoing refinement needs. Given the currently available federal record, the 2025 Audi S5 Sportback appears to be a solid choice with no significant red flags, though buyers should remain aware that long-term reliability patterns are not yet established.
