Stepping from an old A3 to a new one is like going to the supermarket and discovering your favourite brand of washing powder has been ‘reformulated.’

First you wonder why they’ve felt the need to change a formula with which you were already entirely happy. Then you look a little closer and discover the product and its packaging appear to have changed hardly at all and you wonder some more.

But then you read the small print and discover the new product has been built up around an entirely new formula that despite all appearances to the contrary, bears no relation whatever to what you’ve been using for years.

It’s because within the VW group that owns Audi, there exists a culture of never, ever making radical changes to known winners. You can see it all the way from the Porsche Boxster to the Volkswagen Golf, but most of all you can see it in the A3, which has dominated its class since launch.

Chances are you’d need to be an existing owner before you’d be likely to spot the differences between old and new. But make no mistake: the differences are real and, for the dynamically underachieving A3, game changing. Just to give new and old owners clues that this is a new A3, bar from checking the number plate, the mid-life facelift gave the nose a sharper design with the headlights resembling those found on the new A4 and A5

In fact everything has changed – there’s a new platform and every engine is either new or substantially renewed. It’s this change without appearing to change that Audi hopes will provide the right blend of technical improvement with design reassurance to keep the new A3 on top throughout its third generation. Even the mid-cycle facelift sought to rejuvenate rather than radically alter the A3 with new engines and more equipment chief among the additions.

Question is, will it really wash whiter?
