Audi A6 buying guide

Did we mention it has a fantastic interior? Tech-filled and full of design details as crisp as a freshly ironed shirt, the A6’s cabin is a lovely place to drive past the UK’s motorway service stations. It has all the driver aids to take the stress out of tiring drives, not to mention plenty of infotainment functions to explore. Let’s circle back to that shortly.

What Audi A6 trim levels are there?

Poorly equipped Audi A6s just aren’t a thing. The Sport trim is the opening act, but it still gets heated front seats, a rear-view camera, two touchscreens, LED lights and 18-inch alloy wheels.

Audi’s S Line trim is popular on any of its models, and on the A6 it brings sharper bumpers, sports suspension and wheels that are a size bigger. You also get sweeping indicators, showing cars behind you how important you are. Then there’s the Black Edition, which swaps the shiny silver trim for moody black, and also brings privacy glass and a set of 20s.

Vorsprung trim has everything but the kitchen sink – there’s air suspension, a panoramic sunroof, a B&O stereo and extra driver assistance features.

The S6 is basically a standalone model, but even this is available with standard, Black Edition and Vorsprung trim levels.

Audi A6 interior and technology

We know we’ve already touched on this, but the Audi A6’s interior is a highlight. It bears similarities to the cabin you get in the Audi A8, but here you get to enjoy it rather than your chauffeur. There are slashes of silver and darker-than-night black trim all over the place, and the material quality will have you stroking the dashboard like it’s the office cat.

A touchscreen for the climate controls might not seem the most sensible idea. Handily, Audi has given the gearlever a second use, by putting a hand rest on the top of it. Both screens need a firm press but are easy to operate, which’ll be a blessed relief after spending all day speaking in acronyms about hockey-stick sales figures.

Audi A6 engine range explained

Audi A6 40 TDI diesel

Diesel isn’t as popular as it once was, but Audi’s 204hp 2.0-litre diesel engine is a solid match for the A6. It’s almost silent at lower speeds, and never sounds particularly coarse like some rival cars do. Give yourself plenty of time to get to your next client and you could see more than 60mpg. But with its maximum torque figure coming in from just 2,000rpm, the A6 feels like express travel too.

Audi A6 40 TFSI petrol

The lowest-powered petrol matches the diesel’s output, but it’s nearly a second quicker from 0-62mph. Of course, it’s not quite as economical. Just shy of 40mpg is possible, which really isn’t too bad in a car as big as this. 

Audi A6 45 TFSI petrol

Above that is a 245hp 2.0-litre petrol engine that’s found in all sorts of VW Group cars, from the Volkswagen Golf GTI to the Porsche Macan. Here, it’s tuned for refinement, although you’ll still be able to scorch from 0-62mph quicker than said Golf GTI. Thank the standard-fit quattro all-wheel-drive system for that.

Audi A6 55 TFSI petrol

Very occasionally you might stumble across a 55 TFSI engine. This is a 3.0-litre six-cylinder petrol engine with 340hp, which provides incredible smoothness for those not too bothered about the cost of fuel.

Audi A6 50 TFSI e plug-in hybrid

If you spend a lot of time around town and in low-emission zones, the plug-in hybrid A6 makes the most sense. Drive predominantly using electric power and you could see over 200mpg, with the 14.4kWh battery enabling an all-electric range long enough to cover the average daily commute. It’s not solely focused on economy, though, as it’s able to accelerate almost as quickly as the 45 TFSI when the mood takes you.

Audi S6 TDI diesel

Rather unusually, Audi’s hot S6 model is powered by a diesel engine these days. It’s not short of power, with a 3.0-litre V6 diesel churning out almost 350hp. That brawny lump enables a five-second 0-62mph sprint. Or, when you’re not rushing around, you can get up to 40mpg.

Audi RS6 Avant petrol

The most potent A6, the RS6 Avant, comes with a thunderous 4.0-litre V8 petrol engine and a walloping 600hp. Hold on as you can hit A-road speeds in just 3.6 seconds from a standstill. It’s one of the fastest estates on sale. With so much performance, you won’t care that the RS6 only manages 22mpg at a cruise.

Audi A6 FAQs

Like its main rivals, the BMW 5 Series and Mercedes E-Class, the Audi A6 is best known for being a roomy four-door saloon. There’s also an estate version with a monumental boot, and both saloon and ‘Avant’ estate versions come with a glut of engines including petrol, diesel, plug-in hybrid and a fast S6 diesel. On the estate, there’s also the supercar-beating RS6 Avant and an A6 Allroad version that adds chunky cladding and off-road capability.

The current generation of Audi A6 has been on sale from 2018, so you’ll only find the latest model for sale at Motorpoint.

A cornerstone of the Audi range, the A6 has some pretty impressive dimensions. Whichever you pick, you’re getting a car that’s nearly five metres long and over 2.1 metres wide. With its big grille and sharp lines, road presence comes as standard. Its length means there’s an abundance of room for your colleagues to stretch out, and they’ll find headroom is commendable as well.

Boot space for the saloon stands at 530 litres, while the Avant estate ups that to 586 litres and brings a more versatile tailgate (which is also powered). While not quite the biggest in its class, the A6 Avant has plenty of room for large dogs, holiday baggage for families who don’t pack light, or numerous photocopiers.

Whether you pick diesel, petrol or plug-in hybrid, there’s no shortage of power in the A6 line-up – and if you want earth-tremoring power to get to your designated car parking space as quickly as possible, there are a couple of options for you, too. For the mile-munching this car was designed for, the diesel engine makes a lot of sense.

Audi is a premium brand and the A6 is one of its larger, posher cars. Both of those factors mean maintenance costs for the A6 will be a little higher than the average car, with both parts and garage labour being more expensive than more affordable brands.

It's worth spending the money, however, because keeping your A6 in A-grade condition means it'll be worth as much as possible when you come to sell it on.

While it won't suit everyone, the Audi A6 is an astonishingly accomplished car. If you're looking for a practical, spacious saloon or estate car, dripping with the latest technology, and wrapped up in a super-stylish package, the A6 is sure to impress.

It's also a pleasure to drive, with an excellent balance between ride quality and grippy handling that lets it cover hundreds of miles without any fuss whatsoever. The top-drawer refinement and composure means you shouldn't hear any complaints from passengers, either.

Audi as a brand doesn't tend to score extremely well in reliability surveys and the A6's report card isn't much cleaner. Other premium brands like Mercedes, BMW and Jaguar all have similarly disappointing scores. A possible explanation here is that, as upmarket brands, they all pack their cars full of technology, which means more things that could potentially go wrong, unlike cheaper, simpler cars.

Consider adding an extended warranty to your A6 purchase to protect yourself from unexpected repair costs down the line.
