2025 Audi S4

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2025 S4.

Transmission Automatic (S8)

The 2025 Audi S4 is characterized by its S8 automatic transmission and EPA fuel economy ratings of 20/29/24 mpg, anchoring the latest iteration of this long-running model. Early reliability data for the vehicle reflects a quiet entry, with just 3 owner complaints primarily focused on tires alongside a single recall. When measured against the model's broader complaint history spanning 1990 to 2021—which saw a high of 148 complaints in 2000 and a low of just 1 in 1995—this minimal early feedback indicates the 2025 S4 is entering the market with a notably stable foundation.

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 S4 sits beyond the endpoint of the provided federal record, which concludes in 2021; against that final documented span—where 2020 logged 16 complaints and 3 recalls while 2021 logged 2 complaints and 4 recalls—the target year’s early complaints total three across tire and electrical system categories, with zero crash or fire reports. Because the year-by-year dataset contains no recall, investigation, or TSB entries for 2025, the model year has not yet accumulated the reporting history required to establish a reliable trend. Falling at the unrecorded leading edge rather than inside the documented arc, the sparse 2025 data implies neither the elevated complaint volumes seen in 2020 nor the recall frequency of 2021, yet it offers no proven durability benchmark. The record therefore suggests this is a cautiously optimistic but largely unvalidated year to buy, as the absence of red flags in early complaints is encouraging but insufficient to confirm it outperforms the documented 2018–2021 pattern.
