Simply put, the A6 is a joy for both driver and passengers alike. Its potent supercharged V6 engine and slick eight-speed transmission deliver invigorating and effortless power. Available permanent Quattro all-wheel-drive assures traction and contributes to wintertime security. And yet at 22 mpg, fuel economy is quite commendable. But that's just the beginning.

Model History

2026

2026 Redesign Year

The A6 is redesigned for 2026. It’s now built with the same underlying design as the new Q5 SUV and A5 sedan. A sleek new exterior looks like a toned-down version of the all-electric E-Tron GT. For the U.S. market, Audi dropped the A6’s turbo four-cylinder for 2026, so the only engine choice is an updated version of the 3.0-liter turbocharged V6 that was available on upper trims of previous A6 models. A seven-speed dual-clutch automatic transmission and all-wheel drive are standard, and an adaptive air suspension is optional. The interior gets Audi’s Digital Stage setup, complete with multiple LED touchscreens. When we used it on the Q6, we found the Digital Stage took some getting used to and we wished for more physical controls.

2019-Present

Current Generation

The redesigned Audi A6 features lots of new technology, including a new infotainment system. Most versions come with a 2.0-liter, turbocharged four-cylinder engine; a 3.0-liter V6 engine with a mild hybrid system is also available. Both engines are paired with a seven-speed dual-clutch automatic transmission which is short on refinement at low speeds and the car hesitates before launch or from a rolling stop. In our tests the four-cylinder returned a commendable 26 mpg overall. The Audi's agile handling gives it a sporty driving experience. The ride is taut with underlying firmness but still comfortable. The quiet cabin is a delight in terms of fit and finish and the seats are extremely comfortable and supportive. The dual screen infotainment system is daunting at first, but we found it ultimately logical. Forward collision warning and automatic emergency braking are standard.

Updates for 2020 brought a new high-performance S6 with a 2.9-liter V6 turbocharged engine mated to an eight-speed automatic transmission. The Allroad wagon returns and comes only with the 3.0-liter V6 turbo. For 2021 the Premium Plus got standard adaptive cruise control. There's also a new Sport 45 model, which includes a 13-hp boost compared to the standard four-cylinder engine (261 vs. 248). Finally, there's the RS 6 Avant wagon, powered by a 4.0-liter twin-turbo V8 matched with an eight-speed transmission.

A mild update for 2024 brings a new grille, enhanced connectivity features, and a slight power increase for the RS 6.

2012-2018

2012 Redesign Year

The 2012 redesign made the A6 even better, with an upgraded interior, comfortable seats, and a slick eight-speed automatic transmission. Rewarding for drivers and passengers alike. The sweet spot in the range is the Premium Plus trim, although it sacrifices ventilated front seats and a power-adjustable steering wheel, which are available only on Prestige trimmed cars. Unique high-tech features include Google Maps satellite view navigation and a built-in Wi-Fi hot spot. Most A6 buyers will select all-wheel-drive. Choosing between the supercharged V6 and the TDI diesel V6 is tough, as both deliver plenty of power with competitive fuel economy. The diesel was discontinued with the VW emissions troubles.

2005-2011

2005 Redesign Year

The 2005 models brought more powerful engines and more luxury amenities. The base engine became a 250-hp 3.2-liter V6. We found the car comfortable, quiet and refined, but its complicated control interface can be frustrating to use. A V10 was available in the S6 and a 300-hp, 3.0-liter supercharged V6 became standard on all-wheel-drive versions in 2009.

1998-2004

1998 Redesign Year

The A6 features a well-done interior, composed ride, and fairly agile handling. Sumptuous and comfortable, the passenger compartment shows lots of attention to detail. Luxury features are abundant in Audi’s mid-sized sedan, including a heated steering wheel, as well as heated front and rear seats. However, while the Audi is quiet and refined, its driving characteristics are not as engaging as some of its competitors. All-wheel drive (AWD) is a big plus, but exacts a penalty in fuel economy.
