"The Audi A6 Avant estate is practical, economical and fast, with enough room in the back for two adults and all their luggage."
Very few estate cars are as desirable as the Audi A6 Avant. Its handsome exterior and stunning interior combine with lightweight materials to make it the fastest yet most economical version of the Avant so far. Towards the end of 2014, Audi also tweaked the A6's design, to keep it fresh and renew its appeal among company-car and private buyers.
Inside, all models are luxurious and easy to use, with a vast array of optional extras available to create the perfect Audi A6 Avant for you. However, these add-ons are expensive and you'll need to think twice if you don't want to see the list price spiral to more than £50,000.
There's a wide range of engines on offer, too, including a twin-turbo BiTDI diesel that's fast but still highly fuel-efficient, as well as the option of quattro four-wheel drive on almost every model. As of 2014, Audi has removed the slow-selling A6 Hybrid from the range, in favour of an all-diesel line-up. If you really want a petrol-powered Audi A6, you'll need to step-up to the high-performance S6 or RS6 versions.
The Audi A6 Avant comes in three main specifications – entry-level SE, mid-range S line and top-of-the-range Black Edition, with even basic cars boasting sat-nav, leather and four-zone climate control.
This is a very practical and well-thought-out car all round, for families and anyone else who needs a large load bay in the back. The boot is brilliantly designed and generously sized.
Audi is a prestige brand, so the main competitors for the A6 Avant are the Mercedes E-Class estate and BMW 5 Series Touring. For a cheaper alternative, consider the Volvo V70 estate, which is comfortable and very safe, but isn’t as much fun to drive.
Our top recommendation is the Audi A6 Avant 2.0-litre TDI Ultra in S line specification, because it's the cheapest to run as well as having an excellent range of equipment. Just remember to test cars with and without the S line's sports suspension – some find it too firm, but Audi can replace it with standard suspension at no extra cost.
The Audi A6 Ultra diesel model can return up to 64mpg, but general maintenance is pricey
The Audi A6 Avant is a quiet and accomplished motorway cruiser, especially on the standard suspension
Audi A6 SE models have comfortable suspension, but S line models are firm
The Audi A6 Avant's boot is very spacious and versatile
The Audi A6 Avant uses tried-and-tested components from other models in the range
