CarGurus Analysis: 2018 Audi A6
Summary
With 661 currently listed for sale and an average price of $16,832.00, 36.3% of 2018 Audi A6s for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 Audi A6 5 / 5 stars.
70.7% of 2018 A6 models on CarGurus are accident free.
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.

For me Audi interior designs are by far the best. It have all the features I was looking fore and more, and there are much mor features they you can get that my A6 doesn’t have since I got mine used, but Audi offers many more in new models. The most important was getting a 3.0T, I believe if you are getting in a luxury/Sport sedan you don’t really want to go with the smaller engine, the power is excellent especially when entering the highway with fast incoming traffic. I can go on and on about it, but the best is to do a good research and test drive it, then finding the right Exterior interior color combination that you like so you can enjoy driving this piece of engineering every time you get behind the wheel.
