2023 Audi S8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 S8.

Transmission Automatic (S8)

The 2023 Audi S8 is offered with an automatic transmission and EPA fuel-economy ratings of 15/23/18 mpg. Its reliability record is comparatively light: only two owner complaints have been logged, with the top reported area being “Unknown Or Other,” and one recall on file. Against the model’s broader 2003-2026 complaint history—peaking at 13 complaints in 2013 and bottoming at one in 2021—the 2023 model sits near the low end, just above the 2021 minimum and well below the 2013 high, which points to a relatively quiet reliability profile so far.

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 federal record shows complaints rose from 3 in 2003 to a peak of 13 in 2013, then declined to zero by 2017‑2018. Recalls followed a similar pattern, increasing to five in 2013‑2014, falling to two‑three in 2015‑2016, then rising again to four in 2020 and eight in 2021 before dropping to one in 2026. The target year 2023 is not listed in the year‑by‑year data, so its specific complaint and recall counts are unspecified. However, the surrounding years (2021 with 1 complaint/8 recalls and 2026 with 0 complaints/1 recall) indicate a downward trend in both metrics after 2021. Consequently, the 2023 Audi S8 likely benefits from the improving reliability trend, making it a sound choice among used models.
