Silver Audi A6 driving down a city street

Audi A6 review (2018-2023)

The Audi A6 is one of the best premium cars on the market. Available as a saloon or an estate, it has an interior outfitted with beautiful materials and up-to-date tech, and it's good to drive, too. Most versions are very efficient, but there are also high-performance versions to choose from.


  • Excellent level of comfort
  • Huge boot space in both the saloon and estate models
  • Great design and high-quality materials


  • It’s not as much fun to drive as rivals
  • Performance models sacrifice some comfort for speed
  • Some rivals have more boot space


“The A6 is well built, very safe and is excellent over long journeys.”

Packaged in a stylish design, the Audi A6 has lots of equipment and enough interior and boot space for just about every need. It’s well built, very safe and is excellent over long journeys with a good driving position and an excellent infotainment system.

There’s a reasonably capable off-road Allroad version, as well as an estate version called the Audi A6 Avant. All versions of are extremely comfortable and exude an executive feel. There are also performance models, called the S6 and RS 6.

We're focusing here on the latest generation A6, introduced in 2018. You'll also find lots of previous-generation models on the market

What's the interior like?

“The minimalist design makes it feel spacious and upmarket, but some competitors have better tech.”

The A6 has an understated interior design that creates a clean, uncluttered and spacious feel. There’s an executive vibe and the quality of materials is excellent.

The wide centre console houses Audi’s MMI (multimedia interface) infotainment system, which controls everything from the sound system to the sat nav. You can control using the central touchscreen or a control dial by the gearstick, as well as with buttons on the steering wheel. You can also access a range of information through a digital driver display, which sits behind the wheel in place of traditional dials.

Both the saloon and the Avant estate model have very large boots, although rival cars like the BMW 5 Series, Volvo V90 and Mercedes-Benz E-Class have more space still.

What's it like to drive?

“The A6 provides a relaxed drive whether you’re stuck in urban traffic or heading into the country.”

The Audi A6 is about comfort and luxury, providing a relaxed drive whether you’re stuck in urban traffic or heading into the country. Great for long-distance driving, it’s remarkably quiet, even with a diesel engine.

The range of petrol and diesel engines are responsive and economical, although the high-performance S6 and RS6 Avant models sacrifice fuel economy for power and speed.

Most A6 models are front-wheel drive, although some have Audi’s quattro all-wheel-drive system, which gives it extra traction in poor weather or on poor road surfaces.

This version of the A6 uses mild-hybrid technology across its engine range, which means it offers slightly better efficiency over earlier equivalent engines.

Is it cost-efficient to buy and run?

“The diesels provide the best economy, particularly if you travel longer distances.”

The Audi A6 depreciates significantly from new, so you can often find a great deal on a used one. Many have been sold, so there are lots to choose from, and many will have high mileage, further lowering the purchase price.

Running costs are good, with excellent fuel economy from the diesels particularly, while insurance and Vehicle Excise Duty costs are similar to its executive rivals from BMW and Mercedes. More powerful versions are going to cost you more, both to buy and run.

Service, maintainance and repair is likely to cost you more than with less premium brands, but on a par with direct rivals.

Which one is best for you?

The 2.0 TDI diesel or TFSI petrol engines will be a perfect between performance and fuel economy for most, but if you’re really interested in performance the 3.0 TDI is worth looking at.

The SE trim has lots of kit, but look too at S spec cars as many will have extras fitted from new. The S line trim does give you sportier styling but can compromise the A6’s great ride comfort because of its larger alloy wheels.

The Avant is one of the best estates on the road, offering style along with loads of interior space and flexibility.
