Car and Driver has long considered the Audi A6 one of the best luxury midsize sedans on the market. The publication praises the A6's beautifully crafted cabin, composed ride quality, and strong powertrain lineup. The base 45 TFSI's turbocharged four-cylinder is smooth, while the 55 TFSI's 3.0-liter V6 delivers 335 horsepower and effortless acceleration. C/D's testers measured a 0-60 mph time of around 4.7 seconds for the V6 model, making it competitive with rivals like the BMW 540i and Mercedes E450. The quattro all-wheel-drive system provides excellent traction in all conditions, and the optional adaptive air suspension transforms the ride into one of the most comfortable in the segment. The dual-touchscreen MMI interface is sharp and responsive, though some editors lament the loss of physical buttons. Interior materials are top-notch, with available Valcona leather and open-pore wood trim. C/D notes the A6 isn't as dynamically engaging as the BMW 5 Series, but it counters with superior refinement and technology. Recent model years bring standard mild-hybrid assistance for improved efficiency. Overall, Car and Driver consistently recommends the A6, earning it a spot on their editor's choice list with a rating of approximately 4.5 out of 5.

Edmunds' comprehensive review of the Audi A6 awards it high marks across the board, earning it a spot among the top-rated vehicles in the luxury midsize sedan class. The editors praise the A6's sophisticated exterior styling and its impeccably assembled interior, which features premium materials and comfortable, supportive seats. Under the hood, the 3.0-liter V6 in the 55 TFSI trim produces 335 horsepower, propelling the A6 from 0 to 60 mph in a tested 5.0 seconds. The standard quattro all-wheel drive delivers confident handling and all-weather capability. Edmunds highlights the A6's hushed cabin, which makes it an exceptional highway cruiser, and the intuitive voice control system. However, the review notes that the touch-sensitive climate and audio controls can be distracting to use while driving, and rear-seat legroom is slightly tighter than in the Mercedes-Benz E-Class. The A6 allroad variant earns separate praise for its added cargo versatility. Edmunds also commends the A6's strong resale value and comprehensive warranty coverage. With a near-flawless blend of comfort, technology, and performance, Edmunds rates the Audi A6 approximately 4.5 out of 5 stars, making it an Edmunds Editors' Choice winner.
