The All-New 2026 Audi A6 Sedan Has Arrived

Keep in mind that the 2026 A6 Sedan is mechanically unrelated to the fully electric A6 E-Tron despite the shared name—Audi originally changed its nomenclature ethos before walking back the plan earlier this year.

Visually, the sedan retains the wagon’s full-width taillight bar and ditches fake exhausts in favor of real outlets. Aerodynamically, it achieves a drag coefficient of 0.23, making it the most efficient gas-powered Audi to date, though still slightly behind the E-Tron’s 0.21 figure.

The combustion-powered A6 rides on the Premium Platform Combustion (PPC), which it shares with the latest A5. At nearly 197 inches long, the new model grows about 2.4 inches compared to its predecessor, though the wheelbase remains largely unchanged. Wheel sizes range from 21 to 23 inches, with forged options available.

Inside, the cabin carries over the same layout as the Avant, with an 11.9-inch digital instrument cluster and a 14.5-inch central screen. An optional 10.9-inch passenger display fills out the dash, which otherwise looks oddly sparse without it.

The 2026 A6 benefits from a 30 percent increase in sound insulation, partly through the use of acoustic glass in the rear windows. Engine and transmission mounts have been revised, and the dual-clutch transmission features new gear tooth designs to reduce noise and vibration.

The cargo area offers 17.37 cubic feet of trunk space, slightly less than the Avant, and expected to shrink further with plug-in hybrid variants once available.

Powertrain choices include a 2.0-liter turbocharged four-cylinder producing 201 hp and 250 lb-ft of torque and a 3.0-liter V6 mild-hybrid with Quattro delivering 362 hp and 406 lb-ft. A diesel 2.0 TDI version with 48-volt tech also makes 201 hp but produces slightly more torque at 295 lb-ft.

All-wheel-drive models can distribute up to 70 percent of power to the rear axle. Until an S6 variant arrives, the six-cylinder A6 is the top performer, reaching 62 mph in 4.7 seconds with a top speed of 155 mph. An optional rear differential can further improve handling by splitting torque between the rear wheels.

Additional features include four-zone climate control, a 20-speaker audio system, adaptive air suspension, soft-close doors, and a panoramic roof with variable transparency.

Sales begin later this month in Germany with a starting price of €55,500 (around $63,000), with deliveries expected this summer. A North American release will follow, likely as a 2026 model-year replacement for the outgoing A6.
