What is it?
The best selling model in the new A4 range. The 143bhp 2.0TDi will take a shade under half of all A4 sales thanks to being the best all-rounder in the range, combining good performance and fuel economy with Audi's usual attributes of quality cabin, solid build and the in the new A4, a more spacious cabin.
As well as the new skin, the new A4 is substantially new underneath, featuring a new chassis platform, suspension and bodywork. Bigger in all three key dimensions, the new A4 has grown to be not far off the A6. Now the boot is a class-leading 480 litres.
Key tech highlights are a longer wheelbase thanks to a re-packaged engine/transmission that shifts the front axle forward 154mm. The new bodyshell is 10 per cent lighter and 5 per cent stiffer than the outgoing car according to Audi's figures.
In styling, the new A4 is handsome, combining the cool Bauhaus look of the last A4 with a few of the curves that helped make the first A4 a best-seller.
What's it like?
Excellent. The new A4 Is a step-up in refinement and driving dynamics over the old car. The new common-rail diesel is much quieter than the old pump-duse unit and the cabin is noticeably quieter, although the BMW 320d just outpoints it for ultimate refinement.
