If you prefer an interior full of buttons that can easily be found to adjust things like the temperature of the climate control, the Audi A6 Avant may not be the car for you. Audi’s gone big on screens with the A6 - there are two in the centre of the dash, as well as an optional one replacing the dials behind the steering wheel.

We like the techy approach, though. The two middle screens are quick and intuitive to use, each providing haptic feedback. You can control climate features such as the air conditioning and the heated seats using the 8.6-inch touchscreen located low down in the centre console, while above this is the usual 8.8-inch display providing access to navigation, DAB radio, Apple CarPlay and Android Auto. Upgrading this to the 10.1-inch display as part of the Technology Pack is a worthwhile cost, in our opinion.

The finish of the A6 Avant’s cabin is up to usual Audi standards - by which we mean exemplary. It might not quite have the wow factor of the Mercedes-Benz, but it all feels extremely well made and looks pleasingly minimalist.

It’s also very practical. For the driver, it’s one of the most comfortable cars on sale, with plenty of adjustment in the seat and steering wheel making it easy to find a good driving position for drivers of all shapes and sizes. Unfortunately, electric adjustment is an optional extra - an expensive one, at that.

Things are good in the back, with plenty of head and legroom for adults and big windows providing a good view out for children. There’s a caveat - a transmission tunnel running along the length of the car means an adult sitting in the middle seat in the back will find getting comfortable slightly awkward.

On paper, the A6 Avant’s 565-litre boot falls short of rivals - particularly the E-Class’s huge 640-litre luggage space. If you’re after outright practicality, the E-Class is the better option, but don’t dismiss the A6 Avant solely on these figures. Its boot is big and a good shape, while the wide opening makes it easy to load bulky items. Should you need even more space, the rear 40:20:40 split rear bench can be dropped easily.

What's the Audi A6 Avant (2018) like to drive?

• Engines range from 40 TDI S tronic to 55 TFSI quattro S tronic
• Readers report Real MPG to be between 49–55 mpg

There are currently three engine options - two diesels and a petrol, all with mild hybrid assistance. The petrol offering is a 3.0-litre six-cylinder petrol producing 340PS and badged the 55 TFSI. The 204PS 2.0-litre four-cylinder diesel (badged the 40 TDI) will cater for most buyers, although there’s also a 286PS 3.0-litre six-cylinder model (50 TDI). The latter might take you by surprise - its 620Nm of torque means its mid-range acceleration makes overtaking a breeze.

The 50 TDI is let down a bit by its eight-speed tiptronic automatic transmission, which can be irritatingly dim-witted at times. Hit the accelerator for a quick getaway - when joining a roundabout, for example - and it can stutter for a second. Using the paddles mounted behind the steering wheel gets around that to an extent, but no one wants to bother flicking between eight gears in a car like the A6 Avant.

Both diesel engines are very refined, although the V6 can be a little noisy when worked hard. You won’t notice the mild hybrid system kicking in and out, however, with the engine switching off entirely when coasting in a bid to save fuel.

There’s a variety of suspension options available, ranging from the standard springs and dampers on the Sport model to the optional air suspension on the 50 TDI. All models ride surprisingly well, even with large alloy wheels, although the optional adaptive dampers provide the best combination of comfort and sportiness.

In terms of handling, the A6 Avant isn’t as sharp as the Jaguar XF Sportbrake, and the steering isn’t as pleasant as the Mercedes-Benz E-Class Estate, but it does the job perfectly well. Quattro all-wheel-drive is standard on the 50 TDI, ensuring you’ll never struggle for grip - while four-wheel steer is available as an option. This makes the A6 Avant feel more agile at low speeds by turning the rear wheels in the opposite direction as the fronts. It does the opposite at high speed, resulting in a more stable drive. In reality, the rear wheels only turn fractionally, and you’re unlikely to really notice it.

Engine	MPG	0-62	CO2

45 TFSI quattro S tronic	-	-	151–155 g/km
50 TDI quattro	49 mpg	5.7 s	151 g/km
