New & Used 2026 Audi A6 for Sale nearDecatur, IL

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.

Audi positions this redesigned midsize luxury sedan as a premium all-around choice, with a powerful engine, standard all-wheel drive, and a spacious cabin. That makes it appealing if you want the core luxury-sedan formula in one package.

The trade-offs are clear: the interior materials are unimpressive, the infotainment system is poorly executed, and the driving experience is unrefined. So while the A6 covers the basics well, it is less convincing if you expect a fully polished luxury car.

With 35.6% of listings priced as good or great deals, there is at least some market opportunity if you find the right example.

Is the 2026 Audi A6 reliable?

The 2026 Audi A6 is presented as a conventional gasoline luxury sedan with a single turbocharged V6, standard quattro all-wheel drive, and a four-year/50,000-mile warranty. Its powertrain is straightforward for the segment, and Audi’s driver-monitoring system is meant to help guard against misuse of the tech.

Audi also says the A6’s EPA-rated 23 mpg combined is easy to approach in real-world driving, which is a useful sign for day-to-day ownership costs. The first scheduled maintenance visit is on the house.

For used buyers, the main long-term ownership risk is that early-build cars may be stuck with the original interface before the updated system arrives later.

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

Accident-free inventory is excellent at 99.4% — clean inventory, standard diligence applies.

You should still run a history report and prioritize a pre-purchase inspection, especially on a first-model-year redesign. Focus on interior condition, infotainment behavior, and whether the car feels as refined as you expect on the road.

Key things to evaluate:

• Trim level: The base Premium trim gets the essentials, but the Premium Plus and Prestige add more convenience and driver-assist equipment. The base car also misses some of the higher-end hardware found on the upper trims.
• Powertrain: Every 2026 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. Adaptive cruise assist, park assist, and a 360-degree camera are standard on Premium Plus and Prestige.
• Infotainment: You get a standard 11.9-inch digital instrument cluster and 14.5-inch touchscreen, plus standard wireless Apple CarPlay and Android Auto. An optional 10.9-inch front-passenger screen is also available.
• Fuel efficiency: The A6 is rated at 23 mpg combined, 20 mpg city, and 29 mpg highway.

Which 2026 Audi A6 trim should I buy?

The 2026 Audi A6 is offered in 3 trim levels: Premium, Premium Plus, 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 luxury basics. It makes sense if you want the least expensive way into the redesigned car, but it is also the trim most likely to leave you wanting more convenience equipment.
• Premium Plus: This is the best-value trim for most shoppers because it adds meaningful equipment without pushing the price as high as Prestige. You also get more of the driver-assist and parking tech that makes the car easier to live with.
• Prestige: This is the most fully equipped version, and it is the one to consider if you want the most comfort and technology. It also unlocks the most advanced available chassis and convenience content, though the cabin materials still do not fully match the price.

A park-assist system, adaptive cruise assist, and a 360-degree camera system are standard on the Premium Plus and Prestige trim levels.

Is the 2026 Audi A6 safe?

The A6 comes standard with 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.

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:

• 35.6% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 99.4% — clean inventory, standard diligence applies.
• The redesigned model brings a more powerful standard engine, standard all-wheel drive, and a broader luxury-sedan package than before.

The bottom line: The 2026 A6 makes the most sense if you want the redesigned car’s stronger standard powertrain and broad feature set. If you are price-sensitive, a nearby model year may be worth considering, especially if you value a lower entry price over the newest hardware.
