New & Used 2026 Audi A6 for Sale nearMount Horeb, WI

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 choice if you want a powerful engine, standard all-wheel drive, and a spacious cabin. That makes it appealing if you value the core luxury-sedan formula and want a single car that covers the basics well.

The trade-offs are clear: the interior materials are unimpressive, and the infotainment system is poorly executed. The overall driving experience is also unrefined, so the A6 makes more sense if you prioritize the essentials over polish.

The market signal is mixed but workable, with 33.6% of listings priced as good or great deals.

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 seven-speed dual-clutch transmission. That powertrain setup is straightforward for the segment, and Audi says the car’s warranty is comparable to what you’ll get from BMW, Mercedes, and most other luxury brands.

Audi also notes that the A6’s driver-monitoring system is robust, which helps guard against misuse of the tech. On the efficiency side, the car’s 23 mpg combined rating is respectable for a V6 AWD sedan, and the test car averaged 22 mpg in mixed driving.

For used buyers, the main long-term ownership risk is that this is a first-model-year redesign with new tech, so early-build cars may be more likely to expose software or interface issues.

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-year redesign with a lot of new technology. Focus on the condition of the interior materials, the infotainment behavior, and whether the car’s driver-assist features operate smoothly in real-world use.

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 rides on 19-inch wheels with all-season run-flat tires, while higher trims can bring more upscale wheel and package choices.
• 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. Premium Plus and Prestige also add park assist, adaptive cruise assist with automated lane centering, and a 360-degree camera system.
• 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 touchscreen is also available, and Audi says a new interface is scheduled to arrive later in the model year.
• Fuel efficiency: The A6 is rated at 23 mpg combined (20 mpg city, 29 mpg highway), and the test car averaged 22 mpg on a mixed route.

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, but it still gives you the core A6 formula: the V6, standard all-wheel drive, and the main luxury-sedan basics. It makes the most sense if you want the least expensive way into the redesigned A6.
• Premium Plus: This is the best-value trim because it adds meaningful convenience and driver-assist upgrades, including park assist, adaptive cruise assist with lane centering, and a 360-degree camera system.
• Prestige: This is the most fully equipped version, and it’s the one to choose if you want the most upscale feature set and access to the Sport Plus Package.

The safety package note is important: adaptive cruise assist and the 360-degree camera are standard only on Premium Plus and Prestige, not on the base Premium.

Is now a good time to buy a used 2026 Audi A6?

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find decent opportunities.

• Deal availability: 33.6% of listings are priced as good or great deals.
• Inventory: There are 351 listings available.
• Clean inventory: 99.4% 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, helping 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:

• 33.6% 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 gives you a more powerful standard engine, standard all-wheel drive, and a spacious cabin.

The bottom line: If you want the newest gasoline A6 with the strongest standard powertrain and AWD, the 2026 is the one to target. If you’re more price-sensitive, a nearby model year may be worth considering, especially if you want to spend less and can live with older tech.
