Another motor show, another niche for Audi to try and fill. Paris's effort was the TT Sportback concept, which is either a kind of swoopy compact saloon or a TT with two extra doors depending on how you look at it. 

It’s the third such new TT concept this year after the Shooting Brake and Offroad concepts, and the third time I’ve smiled at the lengths Audi is going to to expand its range.

Audi is committed to expanding its range from 50 to 60 models by 2020. The TT is the Audi with the most brand kudos, and the strongest badge, so to it’s the obvious candidate for an expanded line-up, especially when at least two of the three concepts would offer something genuinely new on the market place, even if it may appear tenuous.

“We have 50 cars in our range now and will go to 60 by 2020," Audi tech boss Ulrich Hackenberg said in Paris. "To do that, we will need to create segments. We need additional cars and with the TT there is already a clear market and customers for it. We have a huge advantage with the MQB platform as the underpinnings are already there and we can put a new ‘hat’ on.”
