Quick Highlights:
- The 2026 Audi A6 ditches the old four-cylinder. Now it’s just the 3.0-liter turbo V-6 with 362 hp, which is plenty for cruising around town—and it’s fun if you want to push it a bit.
- Grip isn’t an issue thanks to Quattro all-wheel drive and the seven-speed dual-clutch automatic.
- The Sport Plus package, once only on the S6, adds rear-wheel steering, adaptive dampers, and a firmer suspension—you notice the difference if you like feeling connected to the road.
- Starting at $65,395, the A6 undercuts the BMW 540i and Mercedes E450, giving six-cylinder performance without making you break the bank.
Audi has officially outlined the U.S.-specification of the 2026 A6, and the mods are not mere cosmetic ones. Gone is the old four-cylinder base model, but in its place is a standard 3.0-litre turbocharged V-6. It generates 362 horsepower and transmits power to all four wheels via a seven-speed dual-clutch automatic transmission and Audi’s Quattro system.
With the six-cylinder as the entry model, Audi is placing the A6 head on with six-cylinder editions of the BMW 5 Series and Mercedes-Benz E-Class, two of its oldest competitors.
Powertrain: V-6 or Nothing
Behind the scenes, Audi has gone ahead and taken a very bold step: the 2026 A6 only offers 3. 0-litre turbocharged V-6 engine. It generates 362 hp (270 kW/ 367 psig) and 406 lb-ft (550 Nm) of torque, sufficient to accelerate the sedan to 060 mph in about 4.5 seconds. The seven-speed dual-clutch automatic transmits power to all four wheels and provides it with the surefooted grip that you would otherwise have required in Quattro in Audi.
The A6 is a bit behind the paper on the A6 versus the BMW 540i and Mercedes E450, which both produce 375 hp (280 kW / 381 PS). Practically, however, its all-wheel-drive grip makes it stable, be it you are hairing around a twisting highway or a rainy commute. To the majority of drivers, the V-6 offers them the necessary performance that they cannot feel overstrained.
Handling and Chassis Upgrades
Audi hasn’t left driving enthusiasts behind. The Prestige trim comes with adaptive air suspension as standard, but the optional $5850 Sport Plus package dials things up a notch. Swapping air springs for a stiffer steel-spring setup lowers ride height by 0.8 inches and adds rear-wheel steering, adaptive dampers, a sport rear differential, and 21-inch wheels with summer tires. These upgrades were once the domain of the S6, raising eyebrows about whether Audi plans to bring a U.S.-spec S6 at all this generation.
Trims, Pricing, and Value
The 2026 A6 is offered in three trims:
- Premium – $65,395
- Premium Plus – $68,795
- Prestige – $72,695
The starting price has risen above $65K, but context matters. The outgoing four-cylinder A6 began at $58,100, while the six-cylinder option was already over $62K. Compared with its German rivals, Audi has priced the A6 competitively. The BMW 540i starts at $68,275, while the Mercedes E450 begins at $73,550.
Interior and Technology
Audi calls the new cabin a “business lounge,” and it isn’t wrong. A massive 14.5-inch central touchscreen dominates the dash, paired with an 11.9-inch digital gauge cluster. On the Prestige trim, front passengers also get a 10.9-inch display of their own.
Premium audio comes courtesy of Bang & Olufsen’s 20-speaker, 810-watt system, while available features include a head-up display, Matrix LED headlights, and a four-zone climate system. Rear legroom (37.2 inches) is slightly better than the BMW 5 Series, while trunk space (13.2 cubic feet) lands between the Mercedes E-Class (12.7 cu ft) and BMW (18.4 cu ft).
Exterior and Customization
The Audi A6 2026 appears cleaner, sharper and more confident than ever, which is the result of design-oriented towards the Q5, but applied to a sedan. The available options of the wheels include 19 to 21 inches and the buyers have 11 exterior colours, including bright colours like Ascari Blue, Grenadine Red, Madeira Brown and Midnight Green. To be sporty, the S line Black Optic package also provides some gloss-black evil eye, which make the car look more aggressive on the road.
Specs Comparison: Audi A6 vs BMW 540i vs Mercedes E450
| Model | Engine | Horsepower | Torque | 0–60 mph | EPA Combined | Base Price (incl. dest.) |
| 2026 Audi A6 | 3.0L Turbo V-6 | 362 hp | 406 lb-ft | 4.5 sec | 23 mpg | $65,395 |
| BMW 540i | 3.0L Turbo I-6 | 375 hp | 398 lb-ft | 4.4 sec | 28 mpg | $68,275 |
| Mercedes E450 | 3.0L Turbo I-6 | 375 hp | 369 lb-ft | 4.4 sec | 25 mpg | $73,550 |
Final Thoughts
The 2026 Audi A6 won’t top every spec sheet, and that’s fine. It sits comfortably in the mid-size luxury segment, offering a standard V-6, Quattro all-wheel drive, and a tech-filled cabin, plus the option for S6-grade chassis upgrades. All that comes without pushing the price into six figures, which already makes it stand out against the BMW 540i and Mercedes E450.
It’s the kind of car for drivers who appreciate understated luxury and don’t need to shout from the rooftops about horsepower numbers. The A6 finally feels like it has the mix of refinement and real-world driving chops that it has been chasing for years.
