Currently reading: Five-door Audi TT Sportback concept leaks out ahead of Paris debut
Sketches purporting to be official hint at new Audi TT-based concept that will be Ingolstadt's style-led rival to the Mercedes-Benz CLA

A series of sketches purporting to reveal the sleek lines and exterior styling details of a new Audi TT Sportback concept due to make its world premier at next week’s Paris motor show have leaked to the internet.

The five-door liftback is third in a series of Audi TT-based concepts, following on from the TT Allroad Shooting Brake and TT Offroad concepts revealed earlier this year.

Based on a lengthened version of the third-generation TT’s aluminium and high strength steel platform, itself part of the Volkswagen’s Group’s Modular Transverse Architecture structure, the TT Sportback is said to preview plans for a style-led model from Audi to rival the Mercedes-Benz CLA.

Information accompanying the sketches, all credited to Audi by German media, suggests the Audi TT Sportback concept measures 4470mm in length – making it some 290mm longer than the recently introduced third-generation TT Coupé.

The addition of two conventionally hinged rear doors has been made possible by a lengthening of the three-door TT Coupé’s 2505mm wheelbase. Reports say the TT Sportback also incorporates two individual rear seats that split and fold to extend boot capacity to 850 litres.

Power for Audi’s latest concept is said to hail from the same turbocharged 2.0-litre four-cylinder showcased in the TT quattro Sport concept revealed at the Geneva motor show last March. It is claimed to deliver 414bhp and channel drive through a six-speed S-tronic dual clutch gearbox and quattro four-wheel-drive system.

Audi has made no secret of the fact that it is considering extending the TT line-up beyond the traditional coupé and roadster models.

Speaking at the launch of the TT Offroad concept at the Beijing motor show in April, Audi research and development boss Ulrich Hackenberg told Autocar: “The Audi TT Offroad concept provides a glimpse of how we might image a new model in the future TT family."

What's the issue?

Personally I can't see the problem. Has Aston Martin sales suffered because of the Rapide? I see more new Audi Sportbacks than I see saloons - can't tell you the last time I saw a new A5 3dr. The CLS and CLA appear to be popular and the VW Passat CC or whatever it's called these days, remains more desirable than it's saloon counterpart. I really can't see what's 'niche' or controversial about a 5dr TT.

I was reading an article in a rival mag recently about the launch of the Mark III coupe, and some Audi executive was saying that the TT name should only ever be applied to a sports car. Things change very quickly in the auto industry.

TT or A5 Sportback?

This sketch really looks like a concept for the next A5 sportback. Personally I think this will dilute the TT 'brand', but God knows, every possible niche must be filled
