Audi A6 Avant Review 2024

Audi A6 Avant At A Glance

Honest John Overall Rating
As one of the originators of the sector, Audi has pulled out all the stops with its latest A6 Avant, making it a car that’s one of the best on the market.

+Premium interior with lots of space. Mild-hybrid technology contributes to low running costs, refined ride and very assured handling.

-Dim-witted eight-speed Tiptronic gearbox, not as satisfying as a BMW 5 Series to drive.

New prices start from £43,105
Insurance Groups are between 17–47
On average it achieves 86% of the official MPG figure

The Audi A6 Avant is now an even more stylish and striking machine. Its executive car appearance has been enhanced with bulging wheelarches and long, flowing lines, giving it an imposing look. It’s a tech-fest onboard as well, with multiple screens and touch-sensitive controls making a real step on from the previous A6 Avant. But Audi hasn’t forgotten the many strengths of the old car either, ensuring this latest model still has lots of space on board for passengers and, of course, a voluminous and practical estate car boot. It’s also good to see the choice of engines, which was vast in previous generations, has now started to grow from an initially rather limited level.

Although large estate cars aren’t quite as popular as they once were – blame the ascendancy of the SUV – Audi still hasn’t skimped on creating the latest A6 Avant. It is a beautifully finished machine with real presence. It arguably has more elegance than its supposedly more svelte four-door coupe counterpart, the Audi A7 Sportback.

Audi has a long history of building some of the best estate cars going (which it calls Avants), and this heritage is clear to see here. It is a car enhanced by its voluminous estate car rear end, rather than spoiled by it.

Inside, it has an extremely modern and high-tech feel, thanks to its array of colour screens instead of buttons and dials. There are two screens on the centre console alone, plus you can choose to have the instruments replaced by a third multi-function colour display.

It does all take some getting used to. There’s no longer a physical control to change the climate control temperature, for example – even this becomes a touchscreen operation. But it’s certainly sophisticated and futuristic.

Like its predecessor, this generation of Audi A6 Avant is a very roomy car. the driver’s seat has plenty of adjustability in all directions (it’s just a pity electric seats are optional rather than standard) and there’s loads of legroom in the rear.

It goes without saying that a big estate car should have a big boot, and the A6 Avant delivers here too, with a class-competitive 565 litres with the seats up. No, it’s not as roomy as the Mercedes-Benz E-Class estate, but the Audi A6 Avant’s more svelte rear end is a compromise most won’t consider a step too far. The rear seats fold flat for even more space, in a handy 40:20:40 layout.

Since the launch of the A6 Avant in 2019 the engine range has changed a bit. Both the two V6 motors (the 50 TDI and 55 TFSI) are no longer available to order new, leaving a single diesel option, two petrol engines and a recently launched plug-in hybrid. All latest Audi A6s come with an automatic gearbox and Quattro all-wheel drive is available across the range. 

The diesel is the 40 TDI, a 204PS 2.0-litre four-cylinder engine with mild hybrid technology as standard. Fuel economy is very good and it’s a more responsive and smoother-running engine than many expect. 

For those who prefer petrol, the 40 TFSI and 45 TFSI are both 2.0-litre four-cylinder turbo units with 204 and 265PS respectively. Finally, there's the 50 TFSI e plug-in hybrid with 299PS and an EV-only range of up to 41 miles.

Audi’s engineers tune the setup of their cars to be composed, effortless and assured. The grin-inducing tactility you get from something like a BMW 5 Series is dialled back in favour of a drive that remains calm and collected no matter what speed you’re driving, or what the weather is doing. 

Ride quality is surprisingly supple, even in sportier S line versions. In the previous car, S line spec could feel a bit lumpy in town, but Audi has tuned this out here. The options list features a range of suspension options, including a smooth air suspension setup.

Despite the popularity of SUVs, only the sophistication and carrying capacity of a large estate car will do for some and will certainly make a brilliant family car

Ask Honest John

Is a replacement fly wheel covered by my warranty?

"I bought a used 2017 Audi A6 Avant in April 2021 with 29,000 miles on the clock from a main dealer. It's now January 2022, the car has a mileage of 45,000 and I have had a local mechanic tell me that the flywheel needs to be replaced. There is juddering from the car when pulling away from a standstill. The car has 12 months warranty. Have I got a legitimate case to ask the dealer to repair and replace the fly wheel under warranty?"
The dealer that sold you the car should investigate the problem. Juddering is a tell-tale sign of a clutch and/or flywheel problem. If a fault is found this should be repaired free of charge. For your consumer rights, see:

Can you recommend a good petrol hybrid estate?

"I currently have a 2-litre diesel Toyota Avensis Estate with 94,000 miles since new in 2010. It's very comfortable and has a big boot with seats that fold down for a golf trolley. I travel about 10,000 miles annually with regular long trips. I'm changing cars soon and would like a little more comfort. I'm thinking an Audi estate, either A4 or A6, probably the A6 with larger boot. Ideally for the future I'd like a petrol hybrid. Any suggestions?"
An Audi A4 or A6 sounds like a good option. Also consider a Skoda Superb if you're looking for value for money - we rate the Superb highly and the 2.0 TSI is a good engine. You can get a plug-in hybrid version, which might suit your needs if you can charge a car at home. If you'd like to go down to the plug-in hybrid route, we'd also recommend a Volvo V60 or V90 T8.
