Audi A6 review – an executive saloon all-rounder

​Verdict – is the Audi A6 a good car?

The Audi A6’s biggest problem is its rivals; the Mercedes E-Class is still more comfortable, while the BMW 5 Series is more fun to drive. Despite not standing out in any one area, the Audi is an impressive all-rounder – the interior is luxurious and the technology still impresses even five years after launch. The engines are strong, but there’s no pure-EV, which could be a dealbreaker for company car drivers looking to slash their tax bills.

Audi A6 models, specs and alternatives

Saloon cars may be a lot less common these days on the mainstream market, having lost the battle against big, practical SUVs, but premium, executive saloons like the Audi A6 still have a place thanks to their sleek, sophisticated image and popularity among company-car buyers. 

The Audi A6 has long been the most well-rounded option among rivals such as the comfort-focused Mercedes E-Class and the driver’s choice, the BMW 5 Series, but with all-new versions of those cars having launched for 2024, the A6 is starting to seem a bit long in the tooth. An all-new electric model will arrive in late 2024 to take the A6 name, but a more direct petrol and plug-in hybrid successor will come in the form of the next A7, adopting the brand’s new naming conventions which use even numbers for EVs and odd numbers for traditional combustion-engine models.

The current A6 can be had with either petrol, diesel or plug-in hybrid engines, while those that already want an all-electric executive car will have to turn to the Mercedes EQE or BMW i5 for now.

The best saloon cars to buy in 2024

Even six years after it launched, the A6 remains a premium executive car; its sharp-looking bodywork, distinctive headlights and large grille mean that it manages to be understated yet still very stylish for those who take time for a second look. It does depend on the trim level, though – high-spec cars tend to have flashier trim and large alloy wheels.

The interior is even more impressive than the exterior. The materials inside are of a high quality, so it feels as upmarket as you would expect of an expensive saloon car. The design is simple but classy and best of all there is a huge amount of technology inside, some of which is shared with the more expensive Audi A8.

Every version of the Audi A6 features not one but three screens in the front. Audi’s Virtual Cockpit digital dials are standard and impressive in their execution, while the main infotainment screen sits above a second touchscreen which you’ll use for climate control. 

The A6 received an update in June 2023 with very subtle changes on the exterior and extra kit as standard. Trim levels now comprise Sport, S line and Black Edition, with each version getting an individual look. Matrix LED headlights, dynamic indicators, electrically adjustable seats and Audi’s app store are now standard across the range. 

We recommend sticking to the entry-level Sport trim, as the larger wheels of S Line, Black Edition and Vorsprung cars can make the car more uncomfortable over bumps. Sport offers almost everything you might need, including LED headlights, sat nav, a rear-view camera, leather seats (heated in the front), two-zone climate control and DAB radio.

S Line adds some extra flair with sporty styling and seats, plus larger alloy wheels and Matrix LED headlights, while Black Edition cars feature even larger wheels and black styling elements. The range-topping Vorsprung grade brings huge 21-inch wheels, all-wheel steering and luxuries including a panoramic sunroof and Bang & Olufsen stereo, but doesn’t seem good value at over £20,000 more than the Sport.

The available engines all make use of 'mild-hybrid' technology, which allows the A6 to coast without the engine running. It'll then restart when acceleration is called for, and Audi claims at least a 5% efficiency increase from this system alone.

The ‘40 TDI’ is now the sole choice if you want a diesel engine, and all versions now come with Audi’s quattro all-wheel-drive system. Previously, this 201bhp 2.0-litre engine was also available with two-wheel drive, which made it slightly cheaper to buy and run. It’s bookended by the 40 TFSI and 45 TFSI petrols, and the latter comes with quattro as standard, too. These used to be joined by 3.0-litre V6 petrol and diesel engines, badged 55 TFSI and 50 TDI respectively. It’s probably no surprise that the A6 has long been automatic-only.

High-performance Audi S6 and Audi RS6 Avant models are also offered, and we've reviewed them separately.

The plug-in hybrid A6 50 TFSI e uses a 14.1kWh battery and electric motor along with its 2.0-litre petrol engine. This gives it an electric range of around 42 miles, increasing its figures to 235mpg and cutting CO2 emissions to as little as 27g/km in official tests. The latter is a major advantage for business buyers, slashing the cost of Benefit-in-Kind liability for 40% tax payers by around £4,000 a year. The 55 TFSI e Competition was discontinued in 2021; when it was available it was the most powerful PHEV model with 362bhp - 70bhp more than the 50 TFSI e.

Updated Audi A6 available to order from June 2023

Sharper looks inside and out for the A6, with extra kit as standard

The Audi A6 is being given a set of updates, and the latest version is available to order from mid-June 2023 from £43,965. First deliveries will start a few months later.

There are subtle visual changes, along with updates to the trim level structure and an increase in standard kit. Optional packs will also bundle extra equipment together, making choosing an A6 a simpler affair.

Trim levels will be Sport, S line and Black Edition, with each version getting an individual look. Matrix LED headlights, dynamic indicators, electrically adjustable seats and Audi’s app store will now be standard across the range. On Sport trim, the honeycomb front grille has a Dark Chrome surround, while S line versions get chrome inserts and different front air intakes, plus widened side skirts and 19-inch alloy wheels. While exact details for the Black Edition haven’t been confirmed, we expect it will include a dark finish for exterior trim. A total of 12 paint colours are offered, including the new shades Arcona White and Madeira Brown Metallic, while Grenadine Red Metallic and Ascari Blue Metallic are reserved for Audi S6 performance models.

Inside, the dashboard and headliner are now trimmed in black, while the steering wheel has contrasting stitching and perforated leather. Lower down, the footrests and pedals have been upgraded to stainless steel. S line brings leather and microfiber upholstery with ‘S’ embossed seats, along with ‘S’ badges dotted around the cabin.

The aforementioned new option packs include Audi’s Technology Pack for around £3,000, adding a Bang & Olufsen stereo, extended LED ambient lighting, a 360-degree camera view, Park Assist and a head-up display. Technology Pack Pro costs closer to £6,000 and increases the roster to include four-zone climate control, a panoramic sunroof and remote parking. Rear occupants will also get to enjoy heated seats and USB-C charging ports.
