For The A6 is a smart, spacious saloon with real quality. The cabin is beautifully built and well appointed, while the engines are reasonably frugal.

Against The Audi A6 isn’t as classy as a BMW 5 Series or as good to drive as a Jaguar XF, and the margins aren’t slim on either count.

4 out of 5 stars

The A6 is a high-quality saloon with a spacious, well-built cabin. It’s starting to feel a little old when compared with newer rivals, though.

A6 Our pick

Audi A6 Saloon 2.0 TDI 170 SE 4dr

It's not as smooth or as quiet as the six-cylinder models, but the combination of 168bhp and 50mpg is hard to argue against. Lots of standard kit adds to the appeal, making this our favourite version.

Buyer's notes

Target Price team says:

Audi is renowned for diesel engines and the A6 is a great example of why. Our favourite model has a 168bhp 2.0-litre TDI engine that gives very respectable performance, but still averages the best part of 50mpg. It's not the cheapest model, but we think it's worth paying for.

On the other hand, anyone who's buying with company money may well be attracted by the 2.0-litre TDIe models, which have emissions of just 139g/km and a consequently low tax liability.

The petrol engines, meanwhile, are still pretty strong and will suit drivers with lower annual mileages - they aren't as frugal as the diesels and don't have such strong residuals, but they are much cheaper to buy.

Whatever model you buy, you'll be getting one of the biggest cars in the executive class, backed up with superb build quality, plenty of equipment (for us, SE is the best balance of cost and kit) and a maximum five-star crash-test rating from Euro NCAP.
