Mercedes unveil MGP W01 in Valencia

Pre-season testing gets underway today in Valencia and this morning Mercedes took the covers off its new MGP W01 challenger.

The team, formerly Brawn GP, launched its 2010 livery last week in Stuttgart, but today - at precisely 8.50am - marked the first time that the actual car has been shown in public.

Nico Rosberg gets the honour of testing the new car first before handing over to team-mate Michael Schumacher in the afternoon.

Seven teams are in action today at the Spanish test circuit with Red Bull, Force India and the new t6eams joining the tests at a later date.
