A total of 58 different versions of the 2002 model year Audi A6 saloon and Avant are now available, of which 28 are equipped with quattro four-wheel-drive.
Two alloy block engines - a 2.0-litre four-cylinder with 130bhp and a 3.0-litre V6 with 220bhp - are entirely new to the range, while a number of engines in the existing range have been updated, underpinned by heavily revised suspension for improved ride comfort and dynamics.
The A6 1.9 TDI, for example, has increased in power from 115bhp to 130bhp, yet despite this has been rated as the most economical, least polluting and therefore most tax efficient executive car in the sector. Variable multitronic transmission can be combined with four different engines including a TDI.
On-the-road prices start from £20,450 for the 2.0-litre saloon (pictured below), rising to £40,250 for the 4.2 quattro Sport Avant model.
The most obvious new exterior feature which distinguishes the latest A6 from its predecessor is a new double radiator grille, which originally marked out the V8-powered 4.2 quattro and S6 quattro models. Indicators and headlights now have clear-glass covers, and the light modules in the latter have increased in diameter from 60 to 70 millimetres, improving light output by around 37%.
The distinctive A6 tail has been updated by revised lights and new design indicator lenses, a new high gloss finish for the licence-plate bracket and visible exhaust tailpipes. Customers can now also choose from an extended range of eight different 16-inch and 17-inch aluminium wheels and a total of 16 exterior colours, of which five pearl-effect finishes, four metallic colours and two solid paint finishes are new.
Interior enhancements include new aluminium surrounds for the instrument dials, the gear knob and the gaiter and illuminated rotary light and mirror adjustment switches. For the first time in the A6, a four-spoke steering wheel is available with tiptronic and tiptronic/multi-function capability.
