2023 Audi A6

The 2023 Audi A6 sedan and Avant wagon offer a choice of two engines, with the 45 TFSI sedan in entry-level Premium trim starting the ball rolling at $56,995 (all prices include destination). A Prestige sedan with the larger 55 TFSI engine will set you back $70,595. The cheapest A6 Allroad is $67,995, powered by the same unit, and the S6 starts at $73,795 with its modified three-liter V6. A flagship S6 Prestige tops off the range at $78,495.

Audi’s 45 TFSI engine is a two-liter gas unit that produces 261 horsepower and 273 lb-ft of torque, feeding its power to all four wheels via a seven-speed S tronic automatic transmission. It’s a seriously rapid engine, but the three-liter V6 in the 55 TFSI still trumps it with 335 hp and 369 lb-ft, using the same drivetrain. This is also the only engine available in the Allroad, while the S6 employs a tweaked three-liter V6 that generates 444 hp and 442 lb-ft.

Fuel economy in the 45 sedan stands at an EPA-estimated 24 miles per gallon city, 31 mpg highway, and 27 combined, falling to 21/30/24 for the 55. The S6 returns 19/26/22 mpg.

Cargo capacity for the five-seater A6 and S6 sedans stands at 13.7 cu ft with the rear seats in place, rising to 30 cu ft in the Allroad and Avant.

Safety on every A6/S6 includes knee airbags, cruise control, electrically folding heated and auto-dimming power outside mirrors, and high beam assist.

Lane departure warning is another across-the-range standard alongside front and rear parking sensors, but it’s disappointing that Premium buyers miss out on the top-view camera system, rear cross-traffic assistance, lane guidance, and adaptive cruise control found on higher trims. You’ll need the Prestige to enjoy a head-up display or traffic sign recognition – technology fitted as standard in far more affordable vehicles from other manufacturers.

Every 2023 A6 receives Audi’s virtual cockpit plus – a 12.3-inch TFT screen with three configurable displays. Satellite radio is controlled through a 10.1-inch touchscreen with smartphone mirroring and navigation as standard. Premium Plus models and above benefit from a 3D Bang & Olufsen sound system, Qi device charging, and smartphone signal boosting.

The most affordable A6 comes dressed in full leather, from the heated front seats to the gear shifter and steering wheel. Ambient lighting and a power panoramic sunroof illuminate a cabin equipped with three-zone climate, while stylish touches include aluminum door sills, walnut dash inlays, and a power trunk release. S6 models additionally receive adaptive air suspension behind bigger 21-inch wheels, with Valcona leather interior trim and four-zone climate.

The $2,300 Convenience package adds adaptive cruise with lane guidance and side assistance alerts, a heated steering wheel, a top-view camera system, wireless device charging and signal boosting. On S6 models, the pack’s price drops by $200.

Safety is improved on Premium Plus models with a top-view camera system and rear cross-traffic assistance, alongside matrix-style LED headlights. Lane guidance and adaptive cruise control also come as standard, alongside wireless smartphone charging and signal boosting, plus the aforementioned Bang & Olufsen stereo. Allroad models further benefit from adaptive air suspension and aluminum roof rails, plus bigger 20-inch wheels.

The Executive package will set you back $2,250 on the A6 or $3,250 on Allroad. Both trims receive four-zone climate and ventilated front seats with four-way power lumbar, plus heated rear seats and ambient LED lighting. The sedan benefits from a powered trunk, whereas the Allroad gains adaptive cruise and manual rear-side window sunshades.

S6-specific options include the $4,000 S Sport package, whose red brake calipers and sports exhaust join an uprated rear diff and all-wheel steering. The $1,850 Luxury package extends leather across the dash, armrests, and center console, with individually contoured front seats clad in Valcona/Milano leather alongside memory settings for the passenger.

Power soft-closing doors click into place as you settle into Prestige’s ventilated front seats with four-way lumbar adjustment. A head-up display incorporates traffic sign recognition, projected across the range of the HD LED headlights. Dual-pane acoustic side window glass reduces noise on the move, while four-zone climate joins heated rear seats and ventilated front ones.

The Luxury package mentioned above is reprised on Prestige, costing $2,850 on the sedan and Allroad, but only $1,850 on S6 models despite the latter being unique in receiving front-seat ventilation. The aforementioned S Sport pack is also available on this trim.
