According to germancarblog, besides the three known cars, another new concept is coming to Geneve!

Any idea what? A new vision of e-tron? R8 GT? New sportquattro?

The 80th Geneva Motor Show will serve as the backdrop for several spectacular Audi premieres. International star Justin Timberlake will be unveiling the new Audi A1 during the press conference starting at 1:30 p.m. (CET) at the Audi stand. In addition, Rupert Stadler, Chairman of the Board of Management of AUDI AG, and Michael Dick, Member of the Board of Management for Technical Development, will be presenting the Audi RS 5, the near-production Audi A8 Hybrid show car and an additional concept car.
