Why it stands out

The 2018 Audi A6 stands out as a midsize luxury sedan that blends understated style with a strong emphasis on technology and driving polish. In this generation, Audi had already moved the A6 into a more modern era, with a longer and wider body, a new aluminum-and-steel chassis related to the larger A8’s, and standard quattro all-wheel drive across the lineup. It also brought a notable tech leap, including digital interfaces, standard Apple CarPlay and Android Auto, dual screens, lots of connectivity, and semi-autonomous capability.

For 2018, the A6’s appeal was also rooted in its broad equipment and balanced character. Standard features 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. Available features 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 helped make it feel especially well equipped. Buyers looking for a used luxury sedan with a premium interior, confident handling, and a long list of available technology will find a lot to like here.

There are a few tradeoffs to keep in mind. The A6 was described as having a front-wheel-drive bias, and its fuel economy was disappointing. Its conservative exterior styling may also appeal more to buyers who prefer restraint than to those wanting a more dramatic look. Still, for shoppers who value a refined cabin, strong road manners, and a sophisticated but understated personality, the 2018 Audi A6 remains distinctive.
