In a world dominated by SUVs and crossovers, the classic sedan refuses to throw in the towel. Audi understands this and has just unveiled the brand-new 2026 A6 Sedan, proving that there’s still plenty of room (and investment) for this timeless three-box format. It joins the already revealed A6 Avant wagon, sharing many features but maintaining its own distinct identity.
The Sedan Holds Its Ground: The New A6 Arrives with Renewed Energy
European luxury brands thrived during the golden age of sedans, and that legacy cannot simply be forgotten. Even with declining sales, the demand for the classic style justifies cars like this new A6. At first glance, it may look familiar—especially if you’ve seen the Avant—but it has its own unique features.
Interestingly, Audi showcased the sedan without the S Line package, which typically jazzes up press photos. But don’t be misled; it’s not the “bare-bones” model. And here’s great news for purists: it does NOT feature the split headlights from the A6 E-Tron electric model. Phew! Despite sharing the name, these two cars are completely different under the skin.
Record-Breaking Aerodynamics (But Watch Out for the E-Tron!)
Get ready for the magic number: 0.23. That’s the drag coefficient (Cd) of the new A6 Sedan with a combustion engine, making it the most aerodynamic Audi ever made with this type of engine. This slightly surpasses the 0.25 of the Avant. Every detail, from the roof line to the air curtains and rear diffuser, is designed for efficient airflow.
This efficiency should translate to better fuel economy and quieter highway journeys. However, it’s worth mentioning that the electric “brother,” the A6 E-Tron, is even smoother, with a Cd of 0.21 (if equipped with cameras instead of side mirrors). The race for efficiency is fierce—even within the house!
Design: Familiar, Refined, and… with Real Exhausts!
Visually, the 2026 A6 Sedan inherits the bold front from the Avant, sporting a wide Singleframe grille and sharp LED headlights. The rear is, of course, where it sets itself apart, maintaining the classic separate trunk design. Audi kept the Avant’s wide rear light bar, along with those small black “wings” at the edges, which are honestly not universally loved.
A win for enthusiasts: the dual exhausts are REAL this time! It seems Audi listened to criticisms about the fake exhaust tips on previous models. Another important point: this is a true sedan with a traditional trunk, unlike the confusing A5 “Sedan,” which is actually a liftback (like the old A5 Sportback). The A6 retains its classic elegance.
Inside: Cutting-Edge Technology and Promises of Quality
The interior is essentially the same as the Avant, which means a shower of technology. The digital instrument panel is 11.9 inches, and the central infotainment screen measures 14.5 inches. A third optional screen for the passenger is 10.9 inches, but without it, the dashboard can feel a bit empty, as though it were designed with that screen in mind.
Audi recently admitted that interior quality has faltered in recent years but promises significant improvements in the new A6. Sound insulation has been enhanced by 30%, thanks to acoustic glass (including in the rear windows) and new mounts for the engine and transmission. Even the teeth of the dual-clutch transmission gears have been redesigned to reduce noise. The seals on the doors and windows are also tighter. Will it be enough?
Powertrain: V6 Power Assured (At Least in the U.S.)
Forget the PPE platform of the electric A6. The combustion A6 uses the new PPC (Premium Platform Combustion), the same used by the A5. In Europe, there will be gasoline options (2.0 TFSI with 201 horsepower) and diesel (2.0 TDI also with 201 horsepower), both equipped with 48V mild-hybrid technology with front-wheel drive or Quattro all-wheel drive. The top-of-the-line (for now) is a V6 3.0 TFSI with 362 horsepower and 406 pound-feet of torque, always with Quattro.
For the U.S. market, the choice will be simpler: only the 3.0 TFSI V6 with 362 horsepower will be available, paired with a 7-speed S tronic transmission and Quattro all-wheel drive. Interestingly, the original text mentions that this V6 in the U.S. won’t be hybrid, but then references mild-hybrid technology globally. We’ll await final confirmation for the U.S., but the power is assured! This V6 propels the sedan from 0 to 60 mph in 4.7 seconds.

Space and Practicality: The Essentials of an Executive Sedan
The trunk offers 492 liters of capacity, a decent figure but slightly smaller than direct rivals like the BMW 5 Series and Mercedes-Benz E-Class. The rear seats fold in a 40:20:40 ratio for added versatility. The Avant, of course, provides more space (503 liters with the seats up, 1,534 liters when folded).
Future plug-in hybrid versions are expected to have an even smaller trunk due to the battery. In terms of dimensions, the new A6 is 6 centimeters longer than the previous model, measuring 4.99 meters, but the wheelbase remains practically the same. Wheel sizes can range from 19 to an impressive 21 inches.
Quick Comparison: A6 Sedan vs. Rivals (Estimated)

|---|---|---|---|
| Trunk Space (L) | 492 | 520 | 540 |
| V6 Engine (U.S.) | 3.0 TFSI (362 hp) | 3.0 L6 (B58)* | 3.0 L6* |
| Aerodynamics (Cd) | 0.23 | ~0.23 | ~0.23 |
| Passenger Screen | Optional | No | Optional |
*Power and availability may vary in the U.S.
Pricing and Launch: The Waiting Game and Tariff Concerns
The new Audi A6 Sedan is already on sale in Germany, with prices starting at €55,500 (approximately $63,000 based on direct conversion). Deliveries are set to begin there in the European summer. For the United States, the wait will be a bit longer: the release is scheduled for the second half of 2025, already as a 2026 model.
One concern is the production in Germany (Neckarsulm). If the current 25% import tariff in the U.S. remains, the final price for American consumers could be quite high. We’ll have to wait and see how Audi will handle this issue.
Frequently Asked Questions About the New Audi A6 Sedan
- Do the 2026 electric and combustion Audi A6 share the same platform?
No. The combustion A6 uses the PPC platform, while the A6 E-Tron employs the PPE platform co-developed with Porsche. They are distinct cars under the bodywork. - What engine will the 2026 Audi A6 Sedan have in the U.S.?
Only the V6 3.0 TFSI with 362 hp, a 7-speed S tronic transmission, and Quattro all-wheel drive is confirmed. - Is the new A6 Sedan larger than its predecessor?
Yes, it is about 2.4 inches longer, but the wheelbase is almost the same. - Will there be a new Audi A7 Sportback?
There are no plans for a new combustion A7 Sportback in the immediate future. The A6 Avant will be the only gasoline-powered A6 “hatch.” - When will the 2026 Audi A6 arrive in the U.S.?
The release in the United States is scheduled for the second half of 2025.
The new 2026 Audi A6 Sedan comes with strong arguments: refined design, cutting-edge technology, a promise of improved quality, and impressive aerodynamics. Time will tell if this will be enough to win over buyers in a challenging market, and whether the final price (especially in the U.S.) will remain competitive.
