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:
- The 2026 Audi A5 replaces the A4, combining the classic sedan and A5 Sportback into one highly functional liftback model.
- Audi officially reversed its odd-and-evens naming scheme in February 2025, keeping the gasoline A6 name alongside the electric A6 e-tron.
- The gasoline-powered S6 and A7/S7 Sportbacks have been discontinued in the United States, leaving only high-performance RS variants.
- Audi Signature Care is now standard, covering all scheduled maintenance for the first 3 years or 30,000 miles on all 2026 models.
2026 Audi Sedan Lineup: Key Strategy and Naming Changes
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.

Audi Ownership Cost: Signature Care and Maintenance Standards
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.
