2025 Audi S6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2025 S6.

Transmission Automatic (S8)

The 2025 Audi S6 is a high‑performance midsize sedan built on Audi’s MLB platform, powered by a twin‑turbocharged V6 that delivers strong, responsive power while the S8 automatic transmits it smoothly; its EPA rating of 19 city/27 highway/22 combined mpg reflects a balanced focus on performance and efficiency. With only one owner complaint recorded—centered on the electrical system—and two recalls, the 2025 model’s reliability profile is markedly improved compared to the broader S6 lineage, which peaked at 42 complaints in 2013 and reached a low of one complaint in 1996. This indicates that the 2025 S6 represents a significant step forward in durability within the series, offering researchers a more dependable platform for comparative studies.

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 S6 registers only one federal complaint categorized under the Electrical System, with zero crash or fire incidents reported, representing a continuation of the minimal complaint volumes observed in 2020–2021 (2 and 0 complaints, respectively). This stands in stark contrast to earlier generation peaks such as 2013’s 42 complaints and 2014’s 20 complaints, placing the 2025 model year at the low end of the historical complaint spectrum. While the 2020–2021 period exhibited a concerning upward trend in recalls (rising from 6 to 10 annually) despite low complaint volume, the federal record provided does not specify recall figures for 2025, focusing solely on the solitary electrical complaint. Without data indicating recalls or investigations for this model year, the 2025 S6 presents a favorable complaint profile relative to the generation’s history, though the data does not specify the root cause of the single electrical issue. Given the minimal complaint activity and absence of reported crash or fire concerns, this appears to be a promising year to buy from a reliability standpoint, contingent upon verifying any outstanding recall information outside this dataset.
