UK publication Autocar reports the all-new Audi TT coupe may spawn a range of models, with Hackenberg stating the German luxury brand is "working on future derivatives of the TT".
The company has already shown the genre-melting Allroad Shooting Brake concept, an off-road inspired wagon based upon the TT's underpinnings (pictured above).
"We are looking to see if there is more we can do," Hackenberg is quoted as saying. "Could the TT be extended as a family car?"
What shape a 'family car' version of the TT could take is unclear, though some publications are speculating that a four-door coupe-style sedan could eventuate, namely a vehicle to compete with the likes of the Mercedes-Benz CLA-Class. Any such sedan-style car may be spun off the Audi A3 sedan's underpinnings, rather than be built from a stretched version of the new TT's aluminium hybrid platform.
It's almost certain Audi will offer a third-generation TT Convertible, though no mention has been made of that model as yet. The brand has also showed a high-performance version of the TT, the sport quattro concept, while less than 12 months ago it showcased the lightweight TT Ultra model that shed 300kg over the regular coupe.
