Audi has given its latest insight into plans to extend the third-generation TT family with the unveiling of a new 395bhp, 2.0-litre four-cylinder engine-powered five-door concept called the TT Sportback.

The practical new Sportback, revealed on the eve of the Paris motor show, is the third conceptual derivative of the TT to be aired by Audi in 2014. It follows the stylish TT Allroad revealed at the Detroit motor show in January and the high-riding Offroad shown at the Beijing show in April.

Although all three variants are billed as concepts, they are said to closely preview the new liftback, shooting brake and SUV models that could complement the existing coupé and roadster in a five-strong range of TT models within the next three years.  

“In our TT Sportback, we are revealing a new member of a potential TT family,” said Audi research and development boss Ulrich Hackenberg. His comments follow similar accounts of the TT Allroad and TT Offroad, the latter of which Hackenberg has described as a “glimpse of a new model in the future TT family”.

The TT Sportback draws its styling inspiration from the latest TT coupé, and comes with heavy influences of the Bauhaus design lineage that has shaped the look of the Audi line-up since the mid-1990s.

While it is evident that it is not simply a stretched version of its three-door TT coupé sibling, it is clear from the similarity in appearance that the new five-door is intended to be a member of the same family of models.
