Audi plans to unveil a new design language for its future models, on a large sedan-cum-coupé concept, at the upcoming Los Angeles motor show in November; sources close to the German car maker have revealed to our sister publication, Autocar UK.

The new concept, which is also claimed to provide hints to the appearance of a four-door A9 model planned to sit at very top of the Audi range in international markets, has been created to preview a fresh design direction developed under the company’s new design boss, Marc Lichte – the man behind the look of the latest Volkswagen Golf and Passat.

Official details of the new coupé, which measures more than 5000mm in length and is based around the same MLB platform as the upcoming A8, remain under wraps.

However, an AutocarUK source privy to a series of design proposals of the new Audi suggest it boasts a highly technical look with a newly interpreted single frame grille, hi-tech laser headlamps, precise detailing within its aluminium body structure and defined shutline architecture.

“It builds on the design in place today but takes it to a whole new level. The design department is working very closely with the production department to give future Audi models a more technical look with added accuracy in terms of build – in keeping with their engineering,” said the source to Autocar UK.

As well as previewing the exterior design of future Audi models, the new concept will also showcase new interior developments, including the future direction of the company’s new digital instrument cluster – as found on the new TT – and new connectivity options to be made available on the new A8 and its A9 sibling. The A9 is expected to launch in international markets in 2017.
