"The Audi A6 is the German brand's answer to the BMW 5 Series – and this version is the best yet."
The Audi A6 is an executive saloon favoured by company car drivers and – as the name suggests – executives. It's available in saloon and A6 Avant estate bodystyles with a broad range of efficient and powerful diesel engines, as well as performance petrols in the form of the RS6 Avant.
The A6 mainly competes with the BMW 5 Series, Jaguar XF and Mercedes E-Class, which are all very different. While the BMW has always been the sporty choice, the most recent Jaguar XF has challenged it for this title, while the Mercedes focuses more on comfort and luxury. The A6 has always been the conservative choice, but in its latest iteration, it's a great all-rounder.
The A6 engine range is a comprehensive one, so there should be something to suit all tastes. The most popular choices are the smooth, economical and powerful 2.0 and 3.0-litre diesels – including a twin-turbo 3.0 BiTDI.
The 2.0-litre TDI Ultra is the star if you want the most economical, and will be particularly appealing to company car drivers with claimed fuel economy of 67mpg and just £20 annual tax. In SE trim, this is our pick of the range.
If you want petrol power, there's the S6 which has a powerful 4.0-litre under the bonnet, but this will be costly to run if you’re worried about running costs.
Audi's famous Quattro four-wheel drive system is available across the A6 range for those who want some extra grip, but the A6 is already a good performer on the road. It's not quite as fun as a BMW 5 Series, but it's impressive nonetheless. You can change the way the car performs via the A6's Drive Select system which lets you alter steering, engine and gearbox settings to your preferences.
Inside, the A6 has one of the best interiors out there. It feels solid and high quality and there's a generous amount of standard equipment. Entry-level A6 SE models come with four-zone climate control, cruise control, automatic lights and wipers, sat-nav, DAB digital radio and leather seats. Move up the range to the A6 S line and Black Edition and you get even more kit.
Higher-spec models do come with firmer suspension, which spoils the A6's comfort, but this can be de-selected for no extra cost.
The A6 feels a solid car, and its reliability is backed up by an excellent record in the annual Driver Power survey. It's safe, too, with five stars from Euro NCAP and a long list of standard safety kit.
