Eight years into its fourth generation, the 2018 Audi A6 remains a solid contender in the luxury mid-size class. But its sleek design, intelligent interior, and good powertrain options are offset by a top trim that competes with the slicker A7, a tight back seat, and the lack of a hybrid model.

Best Value

2018 Audi A6 models range in price from $50,675 for one with front-wheel drive in Premium trim and can top out at over $71,000 for a fully-optioned Prestige quattro (all-wheel-drive) model. While the Prestige is equipped with a 340-horsepower, turbocharged 3.0-liter V6; a 252-horsepower 2.0-liter turbo four-cylinder engine is standard on all other trims. We'd forego the $4,600 premium for the V6, but pick the quattro drivetrain for all-season peace of mind and opt for the Premium Plus trim with its access to advanced safety features.

In addition to the Premium model's navigation system, active park assist, rearview camera, and 7.0-inch infotainment screen with Apple CarPlay and Android Auto compatibility, the Premium Plus adds full LED headlights, a power tilt and telescopic steering column, blind-spot monitoring, rear collision mitigation, four-zone automatic climate control, and a Bose sound system.

Performance

Audi A6

Both the turbocharged four-cylinder and supercharged V6 engines offer plenty of power. The seven-speed dual-clutch automatic found on front-wheel-drive models is a big improvement over the previous CVT, while the eight-speed automatic found on quattro models is adept at finding, holding, and swapping gears with ease.

Although the ride is smooth, competitors have caught up with – and, in many cases surpassed – the A6 in this department. At the same time, handling is solid but it lacks the feedback found in the sportier and more powerful S6 model. The A6's powertrain choices, though good, don't include a hybrid.

Style

The A6's subtle, handsome exterior has aged well despite receiving only a single refresh in eight years. Inside, an understated color palette, an elegant low dash, and a pop-up touchscreen keep it from looking too fussy.

At the same time, three adults will find accommodations tight in back, while the A6 looks dated alongside the newer A4 and its sexy alter-ego, the A7, comes with a hefty price premium.

The Best and Worst Things

The A6's combination of conservative good looks and variety of drivetrain choices make it a solid competitor in the mid-size luxury class. At the same time, it faces competition from newer models with more expressive designs and better ride and handling characteristics.

Right For? Wrong For?

Audi A6

The A6 is a great choice for luxury-minded families thanks to its 98 cubic feet of passenger volume, 16 cubic feet of trunk space, wide range of available active safety features, and the option of all-wheel drive.

Despite a range of engine and drivetrain choices, the A6 isn't available as a hybrid. Eco-friendly buyers need not apply.

The Bottom Line

Despite its conservative design and tight rear accommodations, the 2018 Audi A6 is a solid choice in the mid-size luxury class thanks to its smooth ride, elegant interior, and solid engine and drivetrain options.
