Why it stands out

The 2020 Audi A6 stands out as part of the model’s fifth generation, which ushered in the sedan’s modern era. It was longer and wider than the previous generation and gained about 250 pounds, but it also moved to a new aluminum and steel chassis related to the larger A8’s. Audi paired that hardware with a major technology leap, including digital interfaces, standard Apple CarPlay and Android Auto, dual screens, lots of connectivity, and semi-autonomous capability. Quattro all-wheel drive was standard across the lineup, reinforcing the A6’s appeal as a luxury sedan that still delivers confident all-weather traction.

For 2020, the A6’s lineup expanded with the return of the S6, which brought a 444-hp, 2.9-liter twin-turbo V6. That year also marked the return of two wagon options, the RS 6 Avant and the A6 Allroad. The model’s equipment list was already strong, with standard LED headlights and taillights, S-line exterior styling, a power sunroof, tri-zone automatic climate control, and Audi’s Pre Sense City automatic emergency braking. Available upgrades such as adaptive cruise control, Audi’s virtual cockpit, a 360-degree camera, blind spot monitoring, rear cross-traffic alert, a sport suspension, rear side airbags, adaptive suspension damping, all-wheel steering, and a 19-speaker Bang & Olufsen sound system added to its premium feel.

The 2020 Audi A6 is appealing because it blends understated luxury with a high level of technology and a broad range of available features. It is not the most bargain-friendly choice, and the source notes that the model can be pricey relative to some used alternatives. Still, for buyers who want a refined midsize luxury sedan with standard all-wheel drive and a modern cabin, it offers a compelling mix of comfort, capability, and sophistication.
