2026 Audi A6

The 2026 Audi A6 is the brand's conventionally powered midsize luxury sedan. It's bigger than Audi's A3 and A5 sedans but smaller than the flagship A8. The A6 also has a couple of cousins: the A6 Allroad, which is a wagon, and the relatively new A6 Sportback E-tron, which is all-electric. Most notable for this year's 2026 A6 is that it receives a full redesign that includes updated styling, a new engine and an infusion of Audi's latest technology features. Under the hood is a standard turbocharged V6 making 362 horsepower. That's pretty stout — most rival sedans start off with less powerful four-cylinder engines — and should be good for a quick 0-60 mph sprint in 4.5 seconds, Audi says. 

The A6's primary mission, however, is everyday comfort, and it delivers on that front with its smooth ride, impressive standard and available tech features, and a back seat that's roomy enough to seat adults comfortably. Are the changes enough to put the A6 on top of the premium midsize sedan heap? We've yet to fully test the new A6, so it remains to be seen. But it should certainly be a compelling option if you're shopping for a midsize luxury sedan.  

The Audi A6's main rivals are the Mercedes-Benz E-Class and BMW 5 Series. The Audi stands out for its standard turbocharged V6 compared to the base turbocharged four-cylinder engines of the E-Class and 5 Series. Naturally, the base A6 is more powerful than the entry-level offerings of its rivals. However, both also have higher-powered variants in their lineups. The A6 is most comparable to the 5 Series' and E-Class' midlevel six-cylinder trims, the 540i xDrive and E450 4Matic, respectively. With that said, the A6 is the most affordable of the bunch, coming in thousands less than the other two.
