Audi A6 buying guide

Why buy the Audi A6?

The Audi A6 range is made up of stylish premium saloons and estates. They all have comfortable, user-friendly and beautifully made interiors, and they’re relaxing to drive. You’ll get lots of features in every version, and the diesels will give you impressive fuel economy, meaning you can go long distances between fill-ups.

Audi A6 range and updates

The latest version of the A6 has been sold since 2018, when it replaced a version sold from 2011 to 2018. There are four-door saloon models and five-door estate models that Audi calls Avant. The A6 Allroad is a version of the Avant estate with raised suspension and tough-looking cladding around the body, like an SUV. If you want an estate car but need to make occasional trips off-road, the Allroad is surprisingly capable. There’s also the high-performance S6 and even faster RS6.

You have a choice of petrol and diesel engines, and post-2018 A6s are also available with plug-in hybrid power. Even the less-powerful engines give rapid acceleration, while the high-power models can be seriously fast. Manual gearboxes are available, but automatics are much more common. Some models also have four-wheel drive, which Audi calls Quattro.

You can choose from several trim and equipment packages, but the sporty-looking S line and Black Edition are the most popular.

Audi A6 tech and features

Whichever A6 model you go for, you’ll find it packed with equipment as standard. In the latest version, every model has a large touchscreen infotainment system with Apple CarPlay and Android Auto, built-in sat nav and a very smart digital display behind the steering wheel that can show not only your car’s speed and other information but also a high-definition sat-nav map. You’ll also get cruise control, heated leather seats, a reversing camera and a lot more besides. Older versions have a less-advanced infotainment system, but still, have lots of useful features.

Audi A6 running costs and value

In the latest version of the A6, petrol models can give you an average fuel economy of 39-42mpg, according to official figures, and diesels can give 44-64mpg, depending on the model. Older versions are just as economical. The most efficient diesel models are particularly good if you do lots of long journeys because they’re capable of around 1,000 miles on a full tank. Vehicle Excise Duty (car tax) and insurance costs are reasonable for this type of car.

Audi A6 vs rivals

Rivals to the A6 include the BMW 5 Series, Mercedes-Benz E-Class and Volvo S90. Your choice may simply come down to which brand you prefer but the A6 is a great option that’s comfortable, well-equipped, cost-effective and beautifully made.
