Design & Engineering

Audi seems to be on top of its game as far as design is concerned. Both the A4 and A8L are superbly balanced and atreat to look at, and now this new A6 takes the game even further. Yes, it is a bit generic and Audi design cues are allover the car but as far as proportions, forms, detailing and even bright work go, Audis designers dont seem to haveput a pencil wrong. The sweeping roof and rear quarter-glass carry over the previous A6s look and the beltlinereminds you of the earlier car too.

So this is both an Audi and an A6, no question but its still very fresh and new. Those fabulous LED headlamps, thetightly cropped grille and the faux large inlets give it a unique identity. The rear of the car however is very A8,especially the elongated tail-lights and the manner in which the spoiler on the boot sweeps over.

Dimensionally this car has a slightly longer wheelbase and is also slightly wider than before but its overall length is abit less. Also reduced significantly through systematic ef fort is the weight. The new A6 may be built on Audis MLBplatform, also shared with the A4, but there are plenty of aluminium bits here. Bonnet, fender, doors and the boot lidare all made of aluminium and under the skin things like cross-members, suspension towers and even the bulkheadsare made from the lighter material too. The result of all these weight-saving measures is a car that weighs 80kg less

than the outgoing one, which gives it an advantage as far as performance, handling and even fuel efficiency areconcerned.

The A6 also comes equipped with Audis Quattro four-wheel-drive system that gets a 60:40 rear bias. Adaptive airsuspension and Audi Drive Select allow the driver customisable setting for systems like dampers, steering and enginemapping.An interesting feature is how the adaptive restraint system networks with Audis Pre Sense Basic safety system. Itdetects how tall the driver and front passenger are and, if necessary, the airbags can quickly blow down a portion oftheir air volume to cushion the head and chest more gently in a crash!

Interior

Just as avant garde-looking as the exteriors are the gobsmacking insides. Again this is an Audi for sure but with

some new shapes, new details and an even higher standard of fit and finish that makes you want to paw the cabin

almost continuously. The wraparound design that starts with a wedge of wood on the doors is simply stunning and

features from the A8, like the fabulous instrument cluster with the big screen in the centre straddled by raised dials,

the touchpad control on the transmission tunnel and Audis new asymmetric chrome highlights, lift the mood of the

cabin to a different class. And there is visual drama here too. The MMI screen, for example, pops out from behind the

vents or can be tucked away to give back the clean look of the dash.

Long-limbed drivers will find themselves particularly comfortable behind the wheel. There is acres of space for the

driver, adjusting the seat and steering wheel allows you to find the perfect driving position, and visibility is very good

as well even when you reverse. The drivers seat, however, doesnt feel very large and thats the case in the rear as

well. Though the rear seat has loads of legroom and decent headroom too, it is set a touch too low and this adversely

impacts under-thigh support. Its comfy enough at the back but we feel the rear seat could have been slightly larger

and offered more support.

Audi hasnt stinted on features. Standard on the new A6 is the keyless entry and go, sunroof, four-zone climate

control, iPod and Bluetooth connectivity, leather seats, a 20GB hard drive and adaptive air suspension. You can

equip it further with LED headlamps (as fitted to the test car), the MMI touchpad, DVD changer, reverse camera and

a BOSE sound system. And, as expected, there is a long list of safety features too. Its got ESP, ABS, six airbags, the

Pre Sense system and of course the all-wheel-drive grip. Strangely, there is no stop-start or energy recovery system

on the diesel. These will feature on the petrol versions that will debut later though.

Performance & Economy

Audis new-generation 3.0 TDI is nothing short of a gem. A thoroughly reworked motor that now has vastly reducedlevels of internal friction, this V6 diesel is so good that it could be a game-changer for Audi.

For a start it rarely ever feels like a hulking big diesel, either in the manner in which it revs or even how it performsunder load. It may not rev as enthusiastically as a BMW straight six nor have a pleasing snarl but apart from this,Audis V6 has the BMW licked.

First of all, idle is super smooth. There is no diesel clatter, only the faintest of vibrations filters through the bulkhead

and this motor feels so smooth when you tap the accelerator that it all but purrs. And its very responsive as well.Accelerate away from a standstill and it responds almost petrol-like but with plenty of additional torque tossed in forgood measure. Progress is pretty linear too. This motor makes an impressive 51kgm of torque from just 1400rpm, soeven at 1200rpm, theres a huge amount of pulling power ready to be tapped. At moderate revs theres a quiethumming sound from under the hood and just punting the A6 around gives you the feeling you are driving a large-capacity V8.

Devastating is an overused word, but performance for the most part is just that. Once past 2000rpm, the motor justcatapults you forward and the push in the back stays very firm all the way to 4000rpm, soon after which a quickupshift gets the whole process going again. And with approximately 245bhp being unleashed at this engine speed,the scenery comes flying at you with a vengeance. Zero to 100kph takes just 6.3 seconds, making this one of thefastest four-door cars in our market. Overtaking is merely a tap of the throttle away, and the massive bursts of powerunleashed when you go full throttle are truly gratifying. This engines mid-range is its strength and the surge of powerwhen you hit the sweet spot in the rev band is addictive. Get behind the wheel on an open road, and all you want todo is drive, drive and drive and when you get home heres a motor you want to roll up, tuck under your arm and takewith you.

Also well mated and well up to the task is Audis seven -speed twin-clutch automatic. Upshifts are a quick flick of thepaddle-shift away and the gearbox shifts really well in manual mode too, increasing driving pleasure considerably.However, it does become a touch slow to downshift when cruising, and you cant get away from the initial lag , typicalof the twin-clutch system which you dont experience in a conventional torque converter-equipped auto.

The new A6 is lighter, has more gears to play with and is also running an engine that boasts considerably reducedfriction. So its no surprise that this car is much more efficient than the one it replaces. And thats despite not having afully integrated efficiency system similar to Mercs BlueTEC or BMWs Efficient Dynamics.

4/8

Our test showed that the A6 used a litre of diesel to travel 9.3km in city traffic conditions, and efficiency on thehighway was 14.3kpl which is impressive for such a powerful saloon.

Ride & Handling

With its new stiffer chassis and adjustable air springs and dampers, Audi has found a happy compromise as far asride and handling is concerned. The dampers set in Comfort are extremely indulgent and the A6 really did surpriseus with how well it rode. Helping the secondary ride in no small measure are the 225/55-R17tyres whose relatively high profile provide considerable cushioning over bad roads.

The A6 glides over rough sections silently and with very little movement of the body, low speed ride is better thanexpected from an air suspension system. Even wildly undulating surfaces are ridden over with a very high degree of

body control. Large holes, however, do result in a sharp thunk due to the short-travel suspension and the lightweightA6 does shudder a bit over particularly bad patches. Most disconcerting was the fair amount of tyre and road noisewhich is a problem that afflicts other Audislike the A8 and A7 too.

Audi, however, has done well to make Sport mode quite comfortable and useable. Its not as hard -edged or bonejarring as you would imagine and you can enjoy the best of what this car has to offer on some of our better surfacedroads.

The A6 is quite adept at shrink-wrapping itself around you. It feels no bigger than an A4 from behind the wheel, actslike a car with only half its mass when asked to change direction and the Quattro system provides it prodigious griptoo. The A6 is fun to drive but not brilliantly so. Theres a lot of understeer to deal with when pushed hard but thebiggest party pooper is the steering which feels numb and devoid of feel, even in Dynamic mode. As a result, its nota very engaging drive and the brakes feel mushy too.

Also unique for a car in this class is the lift feature that makes the air springs raise the car 20mm to help it clear badroads or extra large speedbreakers at low speed. Very practical.

Verdict

Verdict

9/10

There is no doubt that Audi has taken the game considerably forward with the new A6. It's almost everything luxury

car owners would look for- a class-leading diesel motor that is powerful and incredibly refined, interior appointments

that can embarrass a luxury suite, and a comfortable ride. The A6 isn't particularly engaging to drive but it can still

indulge enthusiastic owners a fair bit. We wish the rear seats were a bit more supportive and there is some road

noise present as well. However, you can't get away from the fact that this is a well rounded and a superbly

engineered car that has certainly set a new benchmark in its class.
