The first generation A6 proved to be a surprise success story for Audi. This was, after all, in its original form, little more than a facelifted version of the Audi 100, which was selling slowly until the range was renamed 'A6' in 1994.
The only major engine changes that were effected in the transformation concerned the turbo diesel version. These were aimed at improving response, reducing vibration and increasing pulling power at lower revs. It's no coincidence then that this variant proved to be a key ingredient in the original A6's contribution to Audi's climb back into British profitability. It's equally no surprise that the first generation A6, which lasted until 1997, excellent car that it is, has proved to be much sought after as a used buy, now that the Audi image is on the up and up.
