Audi A6 Avant estate (2018 - ) review
The Audi A6 Avant features some smart driver assistance features, along with mild hybrid technology and a good range of engines, but it still faces stiff competition from the BMW 5 Series Touring, Mercedes-Benz E-Class Estate and Volvo V90.
Interested in buying an Audi A6 Avant?
How good does it look?
The A6 Avant’s design is sharp and modern, sharing plenty with the flagship Audi A8. Entry-level Sport versions look smart with details like aluminium roof rails and LED lights as standard. The S line spec is sportier looking, though. As well as larger alloy wheels, it sits 20mm lower and gets more advanced LED Matrix headlights and scrolling indicators to help it stand out. Chunkier sills and bumpers add to its presence, although the aluminium-look fake exhausts won’t be to everyone’s taste. Regardless, there’s no doubt buyers choose the A6 because of its contemporary look and premium image.
What's the interior like?
If there’s one thing Audi consistently does very well, it’s interior ambience. From the choice of materials to the level of fit and finish, it sets the bar very high. There are plenty of aluminium flashes on the inner door pulls, surrounding the main dashboard, and centre console. Buyers can choose from more traditional wood finish inlays, or pick something more contemporary.
The driving position has lots of adjustment in all directions, as does the steering wheel, so most drivers will find a good setup easily. The standard seats are also very comfortable, with plenty of support. As with the larger Audi A7 and A8, the centre console features two touchscreen displays, resulting in a clean cabin design with few physical buttons. Not everyone is going to like the lack of buttons or physical controls, but there is haptic feedback from some functions, so you can feel your way around a bit more if you’re concentrating on the road. Optionally, there’s a 12.3-inch digital instrument display, too. The combination of this and the dual screens in the centre makes the A6 feel particularly futuristic inside.
How practical is it?
The A6 Avant comfortably seats four adults, but like many cars designed for all-wheel-drive systems, the rear middle passenger draws the short straw for legroom due to a substantial rise in the floor. Otherwise, in the rear, room for heads, elbows and legs is as good as anything else in the class. Although the A6 Avant has a stylishly sloping rear window, it still holds enough in the large boot (from 565 litres) to compete on a more or less equal with the biggest cars in the class – if not outdoing them. With the 40/20/40 split folding seats tumbled forward, the Audi can swallow 1,680 litres of stuff, which is a lot, if bettered by the biggest cars in the sector. If you frequently carry heavier loads, or plan on towing with the A6 Avant, you may want to consider the optional air suspension as it has a self-levelling function.
What's it like to drive?
There is the choice of four different suspension setups for the A6 Avant. Conventional steel springs come on the base Sport model, and these deliver the most consistent ride comfort. In bends, there isn’t much body lean to speak of, and on the motorway, it feels composed, too. Keener drivers are likely to be drawn to the S line version, as the suspension sits lower, which helps with cornering.
Buyers can specify adaptive suspension that changes with the chosen drive mode, too. The differences are quite subtle, but you can tailor an individual setting. Alternatively, and at a higher cost, there is an air suspension that can automatically self-level and raise the car up when on poor road surfaces. At higher speeds, such as on a motorway, it lowers the car’s ride height to improve aerodynamics and stability. For the most part, this provides a soft and comfortable experience, though it isn’t quite the magic carpet ride you may expect. Sharper potholes and edges still catch it out, and at times it feels fidgety. The good news is that the standard suspension makes for the best option in the A6 Avant.
How powerful is it?
There is a choice of two diesel engines in the A6 Avant, both of which use a ‘mild hybrid’ system to improve fuel economy. The 2.0-litre four-cylinder option (badged ’40 TDI’) is an impressive engine that produces 204 horsepower and uses a seven-speed automatic gearbox to drive the front wheels. The dual-clutch gearbox changes gear smoothly and is quick to drop down a ratio when you need a burst of acceleration. A mild hybrid system utilises a second battery to enable engine shut-off when coasting at higher speeds for short periods of time.
The 3.0-litre V6 diesel doesn’t have to work as hard thanks to its 286 horsepower, yet it often sounds gruffer than the 2.0-litre. Oddly, it feels slower to react to throttle inputs. Audi equips the V6 with a bigger mild hybrid system. That consists of a larger battery that can power the car’s systems, allowing the engine to shut off for up to 40 seconds to save fuel. It mostly does this on the motorway without you noticing.
How much will it cost me?
Of the two engines available, it’s the 2.0-litre diesel most people will choose to buy because of its low running costs. Owning the V6 diesel will cost a bit more to run. Nonetheless, both engines compare well with equivalents from other premium car makers. On top of that, as with most cars in the sector, the Audi A6 enjoys good residual values across its range, which keeps the cost of depreciation down.
How reliable is it?
While the A6 feels well put together and the quality of the finish throughout is among the best in the segment, in Warranty Direct’s Reliability Index, just two Audi models feature in the top 100, and the brand is listed second from bottom in the JD Power 2017 Vehicle Dependability Study. In contrast, owner reviews of the A6 Avant on this website score the car highly for reliability.
How safe is it?
The A6 features a good level of standard safety equipment. This includes front, rear and side airbags, automatic emergency braking, lane departure warning and cruise control that features a speed limiter setting. It hasn’t yet been tested by the Euro NCAP safety organisation, but this car’s predecessor did score full marks when tested, and while the procedure increases in difficulty with time, we expect the current car to perform well.
Choosing the models with four-wheel drive will add to the car’s ability in slippery conditions and there are several driver assistance aids you can choose to add. Matrix LED headlights improve illumination, particularly in darker rural areas, without dazzling other road users, but even more advanced is a night vision camera system that can detect body heat from animals as well as people and highlight their presence in the dashboard for the driver to see. More useful options to consider are the adaptive cruise control for motorway driving, and the cross-traffic system that alerts you to any potential hazards from passing traffic when reversing out of a parking space.
How much equipment do I get?
The A6 Avant comes in two trim levels, Sport and S line. The Sport features 18-inch alloy wheels, LED lights, roof rails, keyless go, and an electrically operated tailgate. Inside, the dual-screen layout comes in all models, with the standard setup being an 8.8-inch top screen and 8.6-inch lower screen. That infotainment system includes sat-nav, DAB radio, ten speakers, smartphone connectivity and a 36-month subscription to Audi’s connected online services – all very worthwhile. Heated front seats include four-way electric lumbar support while a two-zone climate control system adds to cabin comfort.
In the sportier looking S line version, the front seats are upgraded to a more figure-hugging design in leather and Alcantara (faux suede) with the S logo embossed. On top of that, the three-spoke multifunction steering wheel is also covered with perforated leather and contrast stitching, while flashes of brushed aluminium adorn the inside and the door sills feature illuminated S logos. With either trim level you can add more equipment and driver assistance systems optionally. For convenience, these are available in packages.
This is for those that want the versatility of an estate car, but married to the image of a premium badge. The Audi A6 Avant looks sharp and has an interior that will leave you impressed every time you sit in it. Even though there are other equally advanced rivals on sale, the A6 Avant packages its tech in a more desirable fashion that’s sure to make you the envy of your friends and colleagues. In short, this is one of the very best large estates on the market.
