Our Take

from the expert editorial team reviewer Kelsey Mays says Audi's midsize sedan looks great with its upright grille and full LED headlights, and is impressively peppy thanks to its TDI diesel engine. But how does our test model's Sport Package affect ride and fuel economy?

What Is the 2015 Audi A6?

The 2015 Audi A6 is a mid-size luxury sedan with seating for five. It competes with the BMW 5 Series, Cadillac CTS, Jaguar XF and Mercedes-Benz E-Class. It's available in four configurations and three trim levels, including the 2.0T Premium, 3.0T Premium Plus and the 3.0 TDI Premium Plus. The S6 performance version is covered separately on

What's New on the 2015 Audi A6?

For the 2015 model year, a new Warm Weather Package is available featuring four-zone automatic climate control as well as a power rear sunshade and manual shades for the rear side windows.

How Does the 2015 Audi A6 Compare to Other Mid-Size Luxury Sedans?

Drivers looking for a luxury vehicle will not be disappointed by the A6's stylish, well-appointed interior. This well-rounded sedan should meet the performance demands of most drivers, even though the base price is a bit steep for a vehicle with only a four-cylinder engine. Drivers looking for a sports sedan will probably prefer the 310-horsepower 3.0T over the 220-hp 2.0T.

What Features on the 2015 Audi A6 Are Most Important?

Under the hood, the base Audi A6 is powered by a 220-hp, turbocharged 2.0-liter four-cylinder engine. The front-wheel-drive version of the 2.0T comes with a continuously variable automatic transmission, and the all-wheel-drive version is paired with an eight-speed automatic. The 3.0 TDI trim comes with a 3.0-liter turbo-diesel V-6 capable of producing 240 hp. The 3.0T delivers the most power with a 310-hp, supercharged 3.0-liter gas V-6. These higher trims are outfitted with all-wheel drive and an eight-speed automatic transmission as standard equipment.

Significant standard features include 18-inch alloy wheels, a power sunroof, fog lamps, dual exhaust, leather upholstery and heated front seats. Notable options include 19- or 20-inch wheels, the S Line Sport Appearance Package, an MMI multimedia system with Audi Connect, a head-up display, a Bose or Bang & Olufsen sound system, heated rear seats, ventilated front seats and four-zone climate control.

As is required on all new vehicles, the A6 is equipped with front airbags, antilock brakes and an electronic stability system. Six additional airbags come standard. Available safety features include a blind spot warning system, backup camera and night vision with pedestrian detection.

Should I Buy the 2015 Audi A6?

Most drivers will be impressed with all the A6 has to offer. Its efficient, supercharged V-6 performance is noteworthy, and the automaker's attention to detail when crafting the interior does not go unnoticed. One of the few drawbacks is that the backseat may be a little cramped for taller passengers.'s Editorial department is your source for automotive news and reviews.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
