New & Used 2026 Audi A6 for Sale near Missouri

Is the 2026 Audi A6 a good car?

The 2026 Audi A6 earns a 7/10 expert rating. The standout strength is Form and function at 8/10.

It is aimed at you if you want a luxury sedan that covers the basics well, with a powerful engine, standard all-wheel drive, and a spacious cabin. Those strengths make it appealing for everyday use, especially if you value comfort and capability in a midsize sedan.

The trade-offs are clear, though: the interior materials are unimpressive, the infotainment system is poorly executed, and the driving experience is unrefined. Even so, it still comes across as a reasonable value for a luxury sedan that covers the bases well. Good and great deals make up 34.5% of listings, which gives you some room to shop selectively.

Is the 2026 Audi A6 reliable?

The 2026 Audi A6 is presented as a mainstream luxury sedan with standard all-wheel drive and a four-year/50,000-mile warranty, which helps support ownership confidence. Its performance setup is straightforward for the segment, with a turbocharged 3.0-liter V6, a seven-speed dual-clutch transmission, and standard quattro all-wheel drive.

Audi also says the A6 is meant to cover the bases well as a single model, and the available maintenance coverage helps soften early ownership costs. The main long-term risk for used buyers is that this first model year brings a redesigned platform and an interface that is still in flux.

What should I look for when buying a used 2026 Audi A6?

Accident-free inventory is excellent at 97.7% — clean inventory, standard diligence applies.

You should still run a history report and prioritize a pre-purchase inspection, especially because this is a redesigned model year. Focus on cabin condition, infotainment behavior, and whether the car feels as refined as you expect on the road. If you are shopping early-build examples, pay extra attention to software and interface quirks.

Key things to evaluate:

• Trim level: Premium, Premium Plus, and Prestige are the trim levels, and the base Premium is the one most likely to leave you without some of the convenience and driver-assistance upgrades found higher up the range.
• Powertrain: The A6 uses a turbocharged 3.0-liter V6 with 362 horsepower and 406 pound-feet of torque, paired with a seven-speed dual-clutch transmission and standard quattro all-wheel drive.
• Safety package: Standard equipment includes adaptive cruise control, forward-collision warning, automatic emergency braking, rear cross-traffic alert, blind-spot monitors, traffic-sign recognition, parking sensors, and lane-departure warning. Premium Plus and Prestige add park assist, adaptive cruise assist with automated lane centering, and a 360-degree camera system.
• Infotainment: You get an 11.9-inch digital instrument cluster and a 14.5-inch touchscreen, plus standard wireless Apple CarPlay and Android Auto. An optional 10.9-inch front-passenger screen is available, and Audi says an updated interface is scheduled to arrive later in the model year.
• Fuel efficiency: The A6 is rated at 23 mpg combined, with 20 mpg city and 29 mpg highway. In testing, it averaged 22 mpg.

Which 2026 Audi A6 trim should I buy?

The 2026 Audi A6 is offered in 3 trim levels: Premium, Premium Plus, and Prestige.

Here's the short version:

• Premium: This is the entry point, and it gives you the core A6 formula: the V6, standard all-wheel drive, and the main comfort and safety basics. It makes sense if you want the least expensive way into the model and do not need the extra convenience tech.
• Premium Plus: This is the best-value trim for most shoppers because it adds the useful safety and convenience upgrades, including park assist, adaptive cruise assist with lane centering, and a 360-degree camera system.
• Prestige: Choose this if you want the most upscale version of the A6 and are interested in the available luxury and appearance upgrades, including the adaptive air suspension and the optional S Line Black Optic Package.

The Premium Plus and Prestige trims add the most meaningful safety-package upgrades.

This is a moderate buyer’s market, so you can shop selectively without expecting a deep bargain on every listing.

• Inventory: There are 397 listings available.
• Clean inventory: 97.7% of listings are accident-free.

Is the 2026 Audi A6 safe?

The A6 comes standard with the expected array of driver-assist features, including adaptive cruise control, forward-collision warning, automatic emergency braking, rear cross-traffic alert, blind-spot monitors, traffic-sign recognition, parking sensors, and lane-departure warning. A park-assist system, adaptive cruise assist with automated lane centering, and a 360-degree camera system are also standard on the Premium Plus and Prestige trim levels.

Audi doesn’t offer a hands-free driving system, and the lane-centering feature allowed the A6 to wobble from one side of the lane to the other quite a bit. Robust driver monitoring is at least part of the package, which helps guard against misuse of the tech.

It earns a 6/10 safety score from our experts.

Should I buy a 2026 Audi A6 or consider a different year?

If you're weighing the 2026 against nearby model years, here's how to think about it:

Choose the 2026 if:

• 34.5% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 97.7% — clean inventory, standard diligence applies.
• The redesign brings a powerful standard V6, standard all-wheel drive, and a spacious cabin, even if the tech and refinement still need work.

The bottom line: If you want the newest A6 with the strongest standard powertrain and all-wheel drive, the 2026 is the one to target. If you are more price-sensitive, a nearby model year may be worth considering, especially if you want to avoid paying for the first year of a redesign.
