All A6 variants get cleaner engines, plus revised styling, improved transmissions and upgraded infotainment systems
4 September 2014

Audi has brought a series of mid-life changes to its fourth-generation A6 in a bid to improve the competitiveness of the executive class saloon and estate.

Key to the changes is a range of new or updated four-, six- and eight cylinder engines – all claimed to offer added fuel efficiency and lower emissions for EU6 compliancy across the line-up.

They sit alongside revised gearboxes choices, some subtle styling tweaks and new entertainment system options.

Joining the A6 line-up are two fuel efficient "Ultra" models featuring subtle aerodynamic tweaks and a series of weight saving initiatives, including springs made of glass fibre-reinforced polymer (GFRP) on the diesel variant that save a claimed 4.4kg.

Based on the 2.0-litre four-cylinder direct injection petrol powered A6 1.8 TFSI and 2.0-litre four-cylinder common rail diesel propelled A6 2.0 TDI, the new "Ultra" models deliver respective fuel consumption and CO2 emissions of 49.6mpg and 133g/km and 67.3mpg and 109g/km in combination with an optional seven-speed dual clutch gearbox.

Further up the range, Audi has tweaked the 3.0-litre V6 common rail diesel used in the A6 3.0 TDI. In single turbocharged form, it now offers 215bhp or 268bhp.

The more recently introduced twin-turbocharged derivative of the engine has also been upgraded and now kicks out 315bhp in standard form or a more potent 341bhp in a pair of special-edition models. The new variants, dubbed the A6 3.0 TDI competition and A6 Avant 3.0 TDI competition, have been created to celebrated 25 years of TDI technology.

The new A6 3.0 TDI competition performance diesel runs a standard eight speed automatic gearbox. All other engine variants run either a standard six-speed manual or optional seven-speed dual clutch gearbox. The unloved multitronic continuously variable transmission has been dropped.

In A6 models with an engine output over 268bhp, Audi’s quattro four-wheel drive can be supplemented with a so-called sport differential, which aids traction by varying the delivery of power between each individual rear wheel.

In line with the recently introduced facelifted S7, the four-wheel drive S6 and S6 Avant now run an updated version of Audi’s twin-turbocharged 4.0-litre V8 direct injection petrol engine developing an added 30bhp, at 444bhp.

Official performance figures put their 0-62mph times at 4.4sec and 4.6sec respectively. Fuel consumption is a claimed 30.7mpg and 30.1mpg, corresponding to CO2 figures of 214g/km and 219g/km.  

Among the subtle cosmetic changes made to the A6 are stylistic tweaks to the car’s single frame grille, headlamps, bumpers, side sills and tailpipes.

The updated Audi also gets LED headlamps as standard in addition to the existing LED daytime running lights. Dynamic indicators with a sweeping function in the direction of the turn are also standard at the rear and optional for the front light units.

Inside, the A6 receives the latest generation of Audi’s modular infotainment system, while new upholstery and trim colour options are also on offer.

Our Verdict

Audi A6

The Audi A6 rises higher than any model before it and is now a real contender in the mid-size exec market

Looks good to me, as long as you chose wisely with interior colours. But my attention is drawn to

I don't know what a dynamic indicator is, and none the wiser to the merits of a sweeping function, but who in their right mind is going to add this as an optional extra? Never in my life have I stopped in my tracks to gaze at the beauty of an indicator nor have I ever had difficulty in understanding what a flashing orange light means. Talk about gullible punters. Audi have been guilty of placing style ahead of safety - those LED's when they first come out were so bright you couldn't see their indicators. That's been addressed now by dimming the LED's whenever the indicator is in use - whatever they've invented this time, I sincerely hope it doesn't compromise road safety.

A dynamic indicator is supposed to 'indicate' the direction that a vehicle is going turn by a sweeping motion of LEDs, not just flash statically on the right or left of the car. It's meant to allow other road users to see which way the vehicle is turning more quickly.

My first thought is I bet it's not as quick as the hands that popped out from the 'B' pillar on pre-1960 cars. Vorsprung Durch Technik, as they said at Morris Motors and Austin.

I'm trying to think of situations when you can't just tell that by which side of the car the (static) flashing light is on. I'm still thinking....

mustang in america has the indicater showing which way - the three lines flash at different intervals - although I thought this wasn't allowed in the UK as importers had to stop the car doing that.

Unless the law is the indicator has to be orange ratehr than red in the mustang in the usa

Not a massive change, but the subtle changes work well. Lovely interior, much nicer than a 5-series or E-Class

A shame you have to go the 3.0TDI to get a proper automatic. The 7 speed DSG is to much like poorly driven manual at low speeds and when getting on the power from slowing down.

.....Still cost 2k as an elusive option? Otherwise those wheels and tyres look brutal.

341bhp diesel sounds interesting.

Dont like the interior, the choice of woods doesnt suit the rest of the decor, and white carpet, honestly, about as practical as an ashtray on a motorbike, also the stupid ipad slapped on the dash as an afterthought is my biggest dislike of current trends.

    The Citroen C3 Aircross has got funky looks and a charming interior, but it's another small SUV, and another dynamic miss. Numb steering is just one thing keeping it from class best
