2023 Audi S6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 S6.

Transmission Automatic (S8)

The 2023 Audi S6 is equipped with an S8 automatic transmission and carries EPA ratings of 19 mpg city, 26 mpg highway, and 22 mpg combined. Across the S6's complaint history from 1992 through 2021, owner-reported issues have varied widely, from a high of 42 complaints in 2013 to a low of just one in 1996, reflecting a model line with inconsistent reliability patterns over the decades. The 2023 model year aligns closely with that lower end, recording only a single owner complaint — filed under the "Unknown Or Other" category — alongside one recall, which suggests that by this point in the model's evolution, major reliability concerns have largely subsided even if the picture isn't entirely clean.

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 2023 Audi S6 exhibits minimal federal scrutiny, recording only a single complaint categorized under "Unknown or Other" alongside zero crash or fire complaints. When contextualized within the generation's historical arc, this is highly favorable; preceding years saw escalating regulatory activity, with TSBs surging to a peak of 1,111 in 2021 and recalls spiking to 10 that same year. While the data does not specify the root cause for the sole 2023 complaint, the target year's low volume represents a dramatic drop from the complaint peaks of 42 in 2013 and 19 in 2016. Positioned after the generation's highest volume of recalls and TSBs, the 2023 model falls on a downward slope of the complaint arc, implying potential stabilization following the heavily scrutinized 2020-2021 period. Consequently, the 2023 S6 stands as a strong model year to buy, offering a stark improvement in federal complaint metrics over the preceding years.
