2020 Audi A4 allroad

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 A4 allroad.

Transmission Automatic (AM-S7)

The 2020 Audi A4 allroad uses an engine that takes 5.5 quarts of 0W‑30 oil and is paired with a seven‑speed automatic (AM‑S7) to achieve an EPA rating of 27 city, 35 highway and 30 combined mpg. In the 2018‑2024 model‑complaint record, the 2020 model year records the highest total of 154 owner complaints, driven primarily by electrical‑system issues and accompanied by three recalls. By contrast, the 2021 model year logs only a single complaint, making the 2020 allroad the clear reliability low point of the current generation. This concentration of reports suggests that researchers should treat the 2020 model year as an outlier for electrical‑related concerns when evaluating the allroad line.

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 A4 allroad represents a significant statistical outlier in this generation's federal record, with complaints spiking to 154 compared to only 3 in 2019 and 1 in 2021. This year also saw a peak in Technical Service Bulletins at 1,038, more than double the volume recorded for 2018 and 2019. The most frequent issues for 2020 involved the Electrical System and Back Over Prevention, though the data does not specify the root cause for these complaints. While the 2020 model had 3 recalls and 1 crash complaint, these figures remain relatively consistent with the low recall trends of the surrounding years. Due to the disproportionate surge in complaints and TSBs relative to the rest of the generation, this is not a recommended year to buy.
