Review: Audi A6 (2011 – 2018)


Impressive cabin with a straightforward layout. Very quiet and refined on the move. Navigation and leather seats as standard. Efficient 2.0 TDI provides good performance.

Less standard equipment than previous model and optional extras can very quickly push the price up.

Audi A6 (2011 – 2018): At A Glance

Audi's new A6 saloon of 2011 was completely revamped to present an up to the minute alternative to other premium saloons such as the BMW 5 Series, Mercedes-Benz E-Class and Jaguar XF.

It certainly looks good and has a far sleeker and sharper design than before. It doesn't break too many boundaries but then most people who buy these posh saloons don't necessarily want to be noticed. Discreet but stylish is where it's at.

There's a hint of A8 in the styling and this continues inside, where the layout has a modern and minimalist design with great attention to detail and a quality feel throughout. It's a car that you could happily spend many an hour in.

It's just as impressive on the road with superb refinement, ride comfort and very little noise. And then there's economy.

The 2.0 TDI model can average more than 64mpg in some versions. That's according to the claimed figures of course, but in real life you'll probably see 50mpg which isn't at all bad for a big saloon. It doesn't hang around either and has plenty of torque giving a great turn of pace.

It's so good, it's right up there alongside the BMW 5 Series and while it may not quite match the BMW on some fronts, it trumps it on specification thanks to a very high level of standard equipment that includes leather upholstery, cruise control, Bluetooth and navigation.

Full specifications

The interior of the A6 draws on the design of the luxury A8 and A7 Sportback with similar switches, controls and instrument dials which give it a more upmarket feel than the previous A6 and helps lift it above the A4. As you'd expect from a car at this level, there's a very solid and well engineered feel to the interior while the high centre console and slightly angled dash make it feel like it's wrapped around you.

Thanks to a neat design and tactile materials the A6 is far more inviting than the austere E-Class although it doesn't have the charm of a Jaguar XF. It's very simple to get on with though and isn't cluttered with too many buttons, despite all the onboard systems - that's because most are controlled through the MMI (multi media interface) system via the dial next to the gear lever. It's very intuitive and straightforward to use.

Impressively the A6 comes with sat nav as standard. It's a good system and as it works off an SD card is quick at working out routes and has a nice easy-to-understand display. It comes with dynamic route guidance which will take you around traffic and includes Bluetooth so you can take calls on the move.

MMI Navigation Plus is available as an optional extra and gets a larger 8-inch higher resolution screen along with a DVD drive, two card readers and a 20GB of music storage. It also gets Audi's MMI touch with black panel technology - one of Audi's neatest features.

It's a clever touchpad that allows you to actually write out letters and numbers with your finger which the sat nav will recognise, so you can spell out your destination without taking your eyes off the road.

Other new innovations include an optional head-up display similar to the system BMW introduced a few years ago which is available on the latest 5 Series among others.

This projects key data (such as fuel economy and speed) onto the windscreen so that it cleverly appears as if it's floating around 2.5 metres ahead of the driver. However, in a touch of one-upmanship, Audi has developed a full colour display that also lets you know what the speed limit is thanks to a video camera in the rear-view mirror that detects speed limit signs.

Practicality is a strong point for the A6 too. It has a large boot with a wide opening and with 530 litres of space is slightly bigger (by 10 litres) than the 5 Series plus there's a split-folding rear seat as standard so you can carry longer items. Passenger space in the back is good with plenty of headroom and knee space, even for taller people, although the large central transmission tunnel mean it's a real squeeze with three in the back.

What's the Audi A6 (2011 – 2018) like to drive?

You'll probably read it in every single review of the A6 but the obvious comparison has to be with the BMW 5 Series. The big difference is that the 5 Series is rear-wheel drive whereas the standard A6 is only front-wheel drive.

However, with such smooth power deliveries the A6 engines, the difference is not as pronounced as you'd expect. 

Most models come with a quattro version, which helps with traction in the wet, handy when pulling out of a wet junction, plus of course it's handy when it snows - as long as you have the right tyres on. But on many occassions, knowing that all four wheels have traction gives you confidence in situations where a rear-wheel drive car would struggle.

In fact the A6 handles well, very well considering this is a sizeable saloon that's not far off five metres long. Much of that is down to its low weight. At 1575kg (for the 2.0 TDI) it is considerably lighter than diesel alternatives like the 5 Series and E-Class which tip the scales at more than 1700kg. That difference is the equivalent of carrying around two grown men in the back.

This helps it feel nimble and precise on the road with impressive body control in bends or when accelerating and braking hard. The slight disappointment is the steering. Audi has made much about this A6 having more driver involvement but the new electromechanical steering feels detached and could do with more weight.

It's still direct and responsive, but doesn't feel as involving as a 5 Series. However, in normal everyday driving it's really not that much of an issue, so most drivers are unlikely to notice.

What does stand out is the supremely comfortable ride. It's been a criticism of Audi models in the past, especially the sporty S line models, but this A6 has no such issues. It's quiet, forgiving and is just as happy over potholed city streets as it is on bumpy and uneven country roads. This makes the interior a very serene place to be, whether you're driving or being passengered.

The standard suspension set-up is a good balance between handling and ride. Sports suspension which is 20mm lower comes as standard on S line models (it's an option on SE versions) and while it's noticeably firmer in corners, manages not to detract from the overall ride comfort which is an impressive feat. You can also choose the optional adaptive air suspension which continually monitors the road conditions and adjusts the dampers to suit.

The engine line-up is very straightforward. Most people will go for the 2.0 TDI which accounts for three quarters of all models sold. And it's easy to see why. This may be the smallest engine in the range but it's no poor relation and provides more than enough performance.

It's quiet too and while it's never going to be welcome in your local library, it's certainly more than acceptable. That's especially true inside where impressive sound insulation means it only gets loud when you really rev it and there's no need to do that as peak torque is available from just 1750rpm.

The standard six-speed manual gearbox has been much improved with a more positive and less springy action, so driving quickly and smoothly is easier than in the old A6.

The 3.0 TDI is a smooth V6 diesel that's available in two different outputs. The standard front-wheel drive version has 204PS and is available with the Multitronic automatic gearbox while the top quattro version has 245PS and gets a seven-speed S tronic twin-clutch gearbox as standard.

Both models offer impressive performance but it's the more powerful quattro that really stands out thanks to 500Nm of torque - 100Nm more than the front-wheel drive model.

It's amazingly effortless when you ask it to accelerate and yet wonderfully refined too, making it an ideal engine for the A6. There's a typical V6 character to it, with a nice low thrum when you press the accelerator.

I was sold a car that was previously damaged - am I owed compensation?

I’m having a nightmare with my local Audi dealer. They sold me a six month old Audi A6 with 7000 miles on the clock. After owning the vehicle for just over six months, paint has started to come off the rear nearside arch and rust is now showing. Audi deny any knowledge of repairs to the vehicle, despite being the only previous owner. As I was not able to make an informed decision at the point of sale as to whether I wanted to spend £31,000 on a damaged vehicle, I’ve asked for a full refund, which they won’t accept. They also won't accept any kind of reimbursement. They are suggesting it’s something I’ve done to the vehicle. But upon pushing my complaint to the head of business, they've agreed to further repair the car and nothing more. I know from a second opinion that my the car has had the rear quarter panel and rear door resprayed, as well as part of the rear quarter panel replaced. At the very least, in addition to a full Audi repair, I should be given some money back to reflect the original damage undisclosed, as the resale value of my car in a few years time is going to be affected. I’m interested in your views and whether I should pursue a claim for compensation or just settle for the full fix?
Use Small Claims to sue them for a full repaint at a cost of up to £10,000. If the dealer that sold you the car is the only previous keeper then he is lying about not being aware of the damage and that is actually an offence. The Sale and Supply of Goods to Consumers Regulations 2002, is derived from EU Directive 1999/44/EU which became Clauses 48A to 48F inclusive of the Sale of Goods act in April 2003. This reverses the burden of proof so that if goods go faulty within six months after purchase it is deemed they were faulty at the time of purchase and the trader has the onus of proving that the item is not defective due to a manufacturing defect. See: This gives more teeth to the judgement in Bowes v J Richardson & Son. The Consumer Protection from Unfair Trading Regulations May 2008 (CPRs) incorporate The Sale and Supply of Goods to Consumers Regulations 2002 and contain a general prohibition against unfair commercial practices and, in particular prohibitions against misleading actions, misleading omissions and aggressive commercial practices. The Regulations are enforceable through the civil and criminal courts. See These create an offence of misleading omissions which would not previously have been an offence if the consumer had not asked the right questions. So if a salesman knows a car has, for example, been badly damaged and repaired and does not tell the customer, he could later be held liable if the customer subsequently discovered that the car had been damaged and repaired.
