Quick answer: The 2026 Audi A5 is the best overall Audi sedan for most buyers, offering an all-new Premium Platform Combustion architecture, 268 horsepower, standard quattro AWD, and a practical power liftback. For entry-level buyers, the updated A3 offers premium features at the lowest entry price, while the newly redesigned A6 provides cutting-edge digital luxury and executive refinement.
Key takeaways:
In a major shift for the 2026 model year, the Audi sedan lineup underwent a substantial naming and structural reorganization. Audi originally announced a naming convention that would assign even numbers to fully electric vehicles (e-tron) and odd numbers to internal combustion engine vehicles. However, according to an official announcement from the Audi Media Center, the manufacturer reversed this strategy on February 2, 2025, to heightening clarity for customers.
Under the revised system, model numbers represent size and market positioning rather than the fuel type. Despite this reversal, models that had already transitioned kept their new designations. The most notable result is the 2026 Audi A5 replacing the A4 sedan and consolidating it with the outgoing A5 Sportback into a single liftback model.
For U.S. buyers, this strategy also meant streamlining the mid-size and executive segments. The combustion-engine Audi A7 and S7 Sportbacks have been retired after 2025, leaving only the high-performance RS 7. Similarly, the gasoline S6 sedan has been discontinued, and the S6 badge is now carried exclusively by the all-electric S6 Sportback e-tron. For U.S. buyers exploring premium options, the current sedan lineup spans from the subcompact A3 to the flagship A8, with sporty S and RS variants catering to driving enthusiasts.

Here is our comprehensive ranking of the best Audi sedans available for the 2026 model year, evaluated on performance, value, luxury, technology, and everyday practicality.
The 2026 Audi A5 is built on the brand-new Premium Platform Combustion (PPC) architecture. It is powered by a turbocharged 2.0-liter four-cylinder engine producing 268 horsepower and 295 lb-ft of torque. Power is routed through a seven-speed S tronic dual-clutch transmission to standard quattro all-wheel drive. Edmunds testing indicates a 0-60 mph acceleration time of approximately 5.2 seconds.
As noted by editor Austin Parsons in a Car and Driver review, the A5 is a highly competent successor to previous models. Parsons stated that as a replacement for both the A4 sedan and the A5 Sportback, the A5 melds commendable driving dynamics with a spacious interior and liftback practicality. The standard power tailgate replaces a traditional trunk lid, offering a wider cargo opening that makes loading luggage much easier.

It produces a nominal 496 horsepower, which increases to 543 horsepower when launch control is active.
Equipped with a 100-kWh battery pack, the S6 e-tron can charge at speeds up to 270 kW. This allows the battery to go from a 10% to an 80% charge in about 21 minutes at a compatible DC fast-charging station.

Operating a premium luxury sedan requires careful attention to maintenance. To improve ownership confidence, U.S. buyers of Model Year 2026 Audi vehicles receive the new Audi Signature Care package. This complimentary program covers all scheduled maintenance services for the first 3 years or 30,000 miles.
Analysis: The addition of standard Audi Signature Care brings the brand in line with competitors like BMW, significantly lowering the initial cost of ownership. However, buyers should prepare for higher maintenance costs once the 4-year or 50,000-mile basic warranty expires, particularly on complex flagship models like the A8.
Services must be performed at authorized U.S. Audi dealers and occur at fixed intervals:
| Interval Milestone | Mileage Limit | Included Maintenance Services |
|---|---|---|
| Interval 1 | 10,000 miles (or 12 months) | First engine oil change, tire rotation, multi-point safety inspection |
| Interval 2 | 20,000 miles (or 24 months) | Cabin air filter replacement, thorough brake system inspection |
| Interval 3 | 30,000 miles (or 36 months) | Fuel filter replacement, brake fluid flush, coolant check |
Adhering to these intervals is crucial if you need to keep your vehicle running smoothly. If you plan to store your vehicle, you should review how long can a car sit without being driven to protect the battery and tires. While Signature Care handles routine maintenance, issues such as finding out how much is it to fix a car bumper after a minor collision remain the owner's responsibility.

Yes, the gasoline-powered Audi A7 and S7 Sportback models have been retired for the 2026 model year in the United States. The high-performance RS 7 remains, while the redesigned 2026 Audi A6 TFSI adopts a fastback-like silhouette to take over the executive role.
