A design sketch depicting what is believed to be the Audi TT Sportback concept has hit the web.

After the allroad shooting brake and offroad concepts, Audi has prepared another concept based on the third generation TT which could hint at a production model. This time it's a sleek and elegant four-door sportback measuring 4.47 meters and offering enough room for rear passengers. It's also quite practical as folding down the rear seats will grant a cargo capacity of 850 liters.

Little else is known about the vehicle but German media is reporting the Audi TT Sportback concept is powered by a 2.0-liter 4-cylinder TFSI turbocharged gasoline engine delivering 400 HP (294 kW).

It will be showcased starting October 2 at the Paris Motor Show where Audi will also bring the recently unveiled 2015 TT & TT S Roadster.
