CarGurus Analysis: 2021 Audi A6

Summary
With 249 currently listed for sale and an average price of $26,437, 35.3% of 2021 Audi A6s for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2021 Audi A6 4.25 / 5 stars.
81.5% of 2021 A6 models on CarGurus are accident free.
Why it stands out
The 2021 Audi A6 stands out as a used luxury sedan that blends understated style with a strong technology focus. In its fifth generation, it marked a major step forward for the A6 with a longer, wider body, a new aluminum-and-steel chassis related to the larger A8’s, and a cabin built around digital interfaces, dual screens, lots of connectivity, and semi-autonomous capability. Audi’s quattro all-wheel drive system was standard across the lineup, which adds to the car’s appeal for buyers who want confident year-round traction in a premium package.
For 2021, the A6’s appeal also came from its well-rounded equipment and powertrain choices. The lineup included a 248-hp, 2.0-liter turbocharged four-cylinder and a 3.0-liter turbocharged V6 with 335 hp and 369 lb-ft of torque, and both engines used a 48-volt mild hybrid system with a trunk-mounted battery. 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, while available equipment ranged from adaptive cruise control and a virtual cockpit to a 360-degree camera, blind spot monitoring, rear cross-traffic alert, adaptive suspension damping, all-wheel steering, and a 19-speaker Bang & Olufsen sound system. The main drawbacks are that it is unlikely to be a bargain and that some shoppers may want to watch for wear and tear or accident history.

Generally — the 2021 Audi A6 earns a 4.25/5 user rating, which points to strong owner satisfaction for a used luxury sedan. Owners commonly praise its high-tech features, smooth driving experience, and confident performance in various weather conditions. The A6’s use case is especially appealing if you want a premium sedan with standard all-wheel drive, a polished cabin, and a well-rounded mix of comfort and technology. With 35.4% of listings marked as good or great deals, you still have some room to shop selectively.
Is the 2021 Audi A6 reliable?
Owners rate it 4.25/5, a solid signal of long-term satisfaction.
User feedback also highlights reliability and safety as strengths, with many owners describing the car as dependable and trouble-free in everyday use. That said, some shoppers mention wear and tear, so a used example with a clean history and strong maintenance records is the safer long-term bet.
What should I look for when buying a used 2021 Audi A6?
Accident-free inventory is solid at 82.5% — always verify the vehicle history report.
You should prioritize a history report first, then focus on a pre-purchase inspection that checks for signs of prior damage, uneven wear, and deferred maintenance. Because some owners mention wear and tear, pay close attention to the condition of the interior, electronics, and suspension components before you commit.
Is now a good time to buy a used 2021 Audi A6?
This is a moderate market for buyers, so you can shop carefully without expecting a deep bargain on every listing.
- Deal availability: 35.4% of listings are priced as good or great deals.
- Inventory: There are 246 listings available.
- Price trend: Prices have softened 9.18% compared with last year.
- Clean inventory: 82.5% of listings are accident-free.
If you find a listing below $26,209, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2021 Audi A6's resale value?
The current average of $26,422 sits slightly below last year's $29,093.
That price movement suggests the market has cooled, which can make resale timing more important if you plan to sell later. If you buy at the right price now and keep the car in strong condition, you may be better positioned to limit depreciation losses. Vehicles with solid owner satisfaction ratings, like this model year's 4.25/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2021 Audi A6 or consider a different year?
If you're weighing the 2021 against nearby model years, here's how to think about it:
Choose the 2021 if:
- 35.4% of listings are priced as good or great deals.
- Accident-free inventory is solid at 82.5% — always verify the vehicle history report.
- Price trend: Prices have softened 9.18% compared with last year.
- Owners rate it 4.25/5 — a solid satisfaction signal.
The bottom line: The 2021 Audi A6 makes the most sense if you want a tech-rich luxury sedan with standard all-wheel drive and a strong owner satisfaction record. If your priority is value, this year is worth a close look because prices have eased and there are enough listings to compare. If you are especially price-sensitive, you may want to widen your search to nearby model years and focus on the cleanest, best-maintained example rather than the newest badge.
