Audi has uploaded another teaser clip of a mysterious model which will be officially revealed a week from today.

Right from the start we should mention Audi isn't teasing the third generation of the TT or a production version of the sport quattro concept because in the description of the video they say the car's name contains a number. In addition, it won't be the S3 Cabriolet since the model appears to have a hard top while the A3 Cabriolet comes with a cloth roof.

Other noticeable features include a striking yellow paint, Audi's quattro all-wheel drive system and a six-speed manual gearbox.

Our money is on the S1 which will reportedly be introduced next month in Geneva alongside the facelifted A1. An alternative would have to be the RS3 but judging one of the screenshots we took with the side profile, it seems to be too small for an A3-based model.
