Seriously: That diversification of models is a reaction to the demand of the customer for individualization. It is not enough anymore just to choose from three or four different models and then pick the colour and the interior.
There is a demand for niche models, for the inbetween, the not completely defined.
Car makers are only reacting to that trend. In the future a successful carmaker maybe doesn't need to have one high volume model anymore, which carries the rest of the program (like the Golf for VW or the Astra for Opel/Vauxhall), but several not so high volume models.
We'll see in a few years, if the strategy worked or not. Until then I as a petrolhead am thankful for each new, good-looking and interesting car that comes out. And that new Audi definitely falls into that category.
