The new generation Audi A6 from 2018 strikes a balance of waftiness and driving dynamics just right, while technology (and a platform) shared with the A8 means the A6 has got plenty of gadgets to keep passengers entertained. As a comfortable, premium vehicle for covering high mileages, there's not much on the market that'll do the job quite as well. 

All engines - a four-cylinder diesel and a range of six-cylinder petrol and diesels - come with a mild-hybrid system allowing the car to coast under electric power in certain conditions. The most complimentary thing we can say about this system is that the majority of drivers won't notice it. The engine seamlessly drops out during coasting, improving refinement as well as giving fuel economy a boost.

No matter which engine you choose, the A6 is a relaxing car to drive. All models come with progressive steering, which makes the steering quicker the more you wind on lock, while all-wheel steering is available as an option. This turns the rear wheels in the opposite direction of the front at low speeds to reduce the turning circle, while it does the opposite at high speeds in a bid to increase stability.

While the steering isn't the last word in feedback, the ride quality is very good - even on larger alloy wheels. There are no fewer than four different suspension options available, but all generally provide a soothing ride without being excessively floaty.

Where the A6 excels is its interior. It's not as flashy as an E-Class, but it's pleasingly modern with everything well laid out. All models come with a twin-screen infotainment system - the usual touchscreen display in the centre of the dash providing access to navigation, DAB radio and the like, with another one below it providing access to climate features. Both screens use haptic and acoustic feedback, so users hear and feel a click as soon as their finger triggers a function. Strange, but it adds to the premium ambience.

Audi's Virtual Cockpit is also available as part of the optional Technology Pack, replacing the conventional dials behind the steering wheel with a configurable display, allowing to prioritise navigation or the speedo and rev counter.

The biggest issue with the Audi A6 is its price. It may start in the region of £40,000, but you could easily spend £20,000 more by the time you've chosen a desirable engine and a few option packs. That said, you get what you pay for, and premium rivals are equally expensive.

How can I find a car's build date?
"I am going to see a new Audi A6 which at the moment is being stored at the garage with its wrappers on. The salesperson says it has only been in storage for two weeks. Firstly should I worry about how long the car has been in storage? Secondly, how can I find out when the car was built, is there a handy sticker under the bonnet?"
There should be a sticker inside the driver's door jamb. This'll provide details such as the VIN and build date of the car. Lots of new cars have spent extended periods in storage over the last 18 months. It shouldn't be an issue, as the dealer will carry out a pre-delivery inspection to make sure the car is as new. One thing to bear in mind is that a model's standard specification can change regularly. If you're buying a car that was built a year ago, it might not necessarily be identical to a brand new model. Double-check it has everything on it you want.

Does my air conditioning need serviced after two years?
"I have been contacted by my local Audi dealership advising that my car's (Audi A6 with 23,000 miles) air conditioning should be serviced every two years to keep system at optimum. They're offering their technicians to carry out this work for £149. What is your advice on this subject. Many thanks."
If the air condition is working fine (and blowing ice cold air), I'm not sure a service is necessary. Air conditioning systems are self lubricating and it should run trouble free as long you use it every day.

How can I check if alloy wheels I own will fit my new car?
"How can I check if the almost-new set of 18-inch alloy wheels, which I bought for a previous car (Audi A6), will fit my BMW 520d? The tyre sizes are the same (245/45/18). Thanks for your help. "
The first thing you need to check is the wheel's bolt pattern. If the holes in your Audi wheels don't match the studs on the car's mounting hubs, they won't fit. Other considerations include the offset (the distance between the axle pad of the wheel and the imaginary centre line of the wheel) and the size of the centre bore (the hole in the middle of the wheel). If you're not sure, it's a good idea to consult a garage for expert guidance. You'll need to inform your insurance company that you've fitted aftermarket wheels, too.

I want a new Audi A6. My heart is saying petrol but the wallet is screaming diesel - which should I go for?
"I’m considering buying a new Audi A6 next year, but I can’t make up my mind on which engine I should pick. I live in London and don’t do more than 6000 miles per year, I’d say 80% of which is city driving. I occasionally drive out of town at weekends and do one or two euro trips per year. At first glance, the petrol 45 TFSI may sound like the most logical option, but it only comes with Quattro all-wheel drive, does worse mpg, the higher purchase price and the car will depreciate more after 4 years (according to Audi’s officials PCP examples). The diesel is slower than the petrol (204PS vs 245PS) and probably won’t like short trips in London‘s congested traffic too much. Yes, it comes with SCR Ad-Blue system so the DPF should cope, but I’m worried about buying diesel with my mileage and usage. However, the diesel comes with a range of attractive benefits (the opposite of the petrols cons). To cut a long story short, the heart is saying petrol but the wallet is screaming diesel. Which voice should I listen to?"
Petrol. Diesels make no sense for 6000 miles a year, mainly in London.
