Sauber are the first of the 13 Formula One teams to announce the unveiling of their car ahead of the new season.

Team principal Peter Sauber and director Willy Rampf are to take the wraps off their challenger at the Valencia circuit on January 31 ahead of the first test session that runs from February 1-3.

The team claim both drivers will also be on hand, although as yet Sauber have only confirmed Kamui Kobayashi, with a number of names in the frame for the second seat.
