2020 Audi S8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 S8.

Transmission Automatic (S8)

The 2020 Audi S8 pairs its automatic transmission with EPA fuel economy ratings of 13 mpg city, 22 mpg highway, and 16 mpg combined, while requiring 10.0 quarts of 0W-30 engine oil for service intervals. Reliability data shows this model year generated only three owner complaints—predominantly regarding the engine—alongside five recalls. Within the broader 2003–2026 production span, where complaint volumes have ranged from a high of thirteen in 2013 to a low of one in 2021, the 2020 model lands near the favorable end of the spectrum, positioning it as a relatively low-issue year for the nameplate.

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 2020 Audi S8 marks the launch of a new generation, and its federal record reflects a typical first-year pattern: zero consumer complaints on file but a substantial 970 technical service bulletins—the highest in the entire dataset—indicating that Audi was rapidly issuing service guidance to address early-production issues. This stands in stark contrast to the preceding 2017–2018 model years of the prior generation, which had settled to just 339–410 TSBs and only one to two recalls each, suggesting the old platform had matured. However, the 2020 model carries four recalls with no investigations, and the following year (2021) saw recalls double to eight while TSBs climbed further to 1,106, signaling that problems were still being identified well after launch. The three complaints on record for 2020 span the engine, electrical system, and powertrain/electrical categories, with one fire complaint noted, though the data does not specify root causes for any of these issues. By 2026, the record shows just one recall and 129 TSBs, suggesting the platform eventually stabilized. **Takeaway:** The 2020 S8 is a first-year model with an unusually high service-bulletin count and a recall profile that worsened the following year, making it a year to approach with caution—buy only if all four recalls have been verified as completed and a pre-purchase inspection specifically checks for open TSB-related repairs.
