CarGurus Analysis: 2021 Audi A6
Summary
With 241 currently listed for sale and an average price of $27,027.00, 34.9% of 2021 Audi A6s for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2021 Audi A6 4.25 / 5 stars.
85.1% of 2021 A6 models on CarGurus are accident free.
Why it stands out
The 2021 Audi A6 stands out for blending understated luxury with a strong technology focus. In the fifth generation, it was longer and wider than the previous generation and gained about 250 pounds, while also moving to a new aluminum and steel chassis related to the larger A8’s. Audi also gave it digital interfaces, standard Apple CarPlay and Android Auto, dual screens, lots of connectivity, semi-autonomous capability, and standard quattro all-wheel drive, which makes it feel especially modern and well equipped for a used luxury sedan.
It also offers a balanced powertrain setup. The fifth-generation A6 initially had two powertrains, both with a 48-volt mild hybrid system and a trunk-mounted battery: a 248-hp, 2.0-liter turbocharged four cylinder and a 3.0-liter turbocharged V6 with 335 hp and 369 lb-ft of torque. Both engines were paired with a new seven-speed dual-clutch automatic. Standard equipment included 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, while available features ranged from adaptive cruise control and a 360-degree camera to blind spot monitoring, rear cross-traffic alert, adaptive suspension damping, all-wheel steering, and a 19-speaker Bang & Olufsen sound system.
For buyers, the appeal is the A6’s mix of premium feel, technology, and everyday usability. It is not the cheapest choice, and the source notes that the 2021 model has higher-than-average reliability ratings with an average list price around $27,920. Owners also tend to praise its high-tech features and smooth driving experience, along with its performance in various weather conditions. At the same time, some shoppers may want to keep in mind the concerns about wear and tear and past accident records.
