Audi A6 2.4 2005 review

Europeans have transcended this bias fully grasping the diesel to the extent where Euro carmakers spend most of their engine development budgets on diesels.

They use less fuel, last longer and pollute less.

Audi is at the forefront of passenger car diesel technology and has a brace of turbo oil burners that would make other manufacturers green with envy. The 2.5 V6 in Allroad is impressive, the 2.0 four in A3 is extraordinary but the 165kW/450Nm 3.0 V6 in A6 is sensational.

Here is an engine that will deliver around 1000km on a tankful, has more torque than the 4.2-litre petrol V8 and runs sweetly and smoothly while propelling the big A6 like a sports saloon. There really is no down side apart from getting that repulsive smell on your hands at the bowser. Wear gloves and besides, you won't have to make many visits.

The A6 diesel ain't cheap at just on 100 grand but it feels like the sort of car you could buy now and keep for 20 years.

Average that out.

This is the new big grille A6, something I was initially not keen on.

I have changed my mind and now think it's a positive feature – imposing, majestic even and still with a distinctive Audi look.

The rest of the vehicle is new too, again with those classy Audi lines now with a more "technical" edge.

It commands plenty of attention on the road.

Inside is typically sleek and extremely well executed featuring a sweeping dash with smooth lines and integrated console, beautiful use of colour and texture, function – among the best in the business.

Pretty well nothing is left out of the car in terms of features but there would certainly be options available. Plenty of high tech electronic goodies populate the interior.

It rolls on 17in wheels with low profile rubber and has a firm, sporty ride. Some may not like this aspect of the car. The steering is similarly sporty, firm and direct.

Drive is by all wheel drive quattro through a six speed automatic offing tiptronic selection through various devices.

Numerous electronic dynamic controls aid handling and safety. ESP is included in the package. It selectively brakes each wheel to avoid skidding.

Engine performance is strong with heaps of torque instantly available and strong acceleration across the range.

The auto is smooth and willing and apart from some rumbling at idle, you could be driving the 3.0-litre petrol V6.

The hand brake is electrically operated and the lights and wipers have auto on function.

I couldn't figure out how to turn off the aircon. Technology challenged I suppose.
