Audi is no doubt jealous of the runaway success that is the Mercedes-Benz CLA Class. It has attracted the affluent under-40 buyers that are very sought after by luxury automakers right now. The TT has the style and sex appeal needed to attract this demographic, but many of these people have children, and need something a bit more practical, and the A3 just isn't terribly sexy.
That's why this idea is being kiced around: a family friendly version of the TT. This would probably either take the form of a shooting brake, much like the recent TT concepts, or a miniaturized version of the A7 "four-door coupe." We'd love to see either version.
