2020 Audi A6 allroad

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 A6 allroad.

Transmission Automatic (AM-S7)

The 2020 Audi A6 allroad is an elevated off-road-oriented wagon built on Audi's MLB platform, powered by a turbocharged engine paired with a seven-speed automated manual transmission (AM-S7), and requiring 8.0 quarts of 0W-20 viscosity oil for service. EPA fuel economy estimates for this model year stand at 20 mpg city, 26 mpg highway, and 22 mpg combined. With 8 total owner complaints recorded and 4 recalls, the 2020 model sits within a complaint history spanning 2020–2026 that peaked at 24 complaints in 2021 before declining to just 1 complaint by 2025—a trajectory suggesting improving reliability perception across the lineup, though the electrical system emerged as the most frequently cited concern area for this generation.

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 A6 allroad opens the federal record with 8 complaints and 4 recalls, a baseline that appears modest until contrasted with the 2021 model year, which more than triples complaints to 24 and recalls to 12 while TSBs surge to 1,311. Subsequent model years 2024 through 2026 show a sharp decline to near-zero complaints (0–2) and a single recall each, with TSB volume tapering from 675 to 127. The 2020 complaint profile centers on the electrical system (three reports) plus isolated items involving structure, powertrain-electrical integration, and forward-collision/lane-departure functions; the data does not specify root causes. No crash or fire complaints were recorded for 2020. Positioned just before a pronounced 2021 spike, the 2020 model year sits at the quieter leading edge of the generation’s documented federal activity. For a buyer prioritizing a lower complaint and recall footprint within this generation, the 2020 represents a comparatively favorable entry point.
