First day of testing this week for Scuderia Ferrari Marlboro, working from today at the Catalunya Circuit, near Barcelona.

The F2007 did not make a very positive debut on the new layout of the Catalan track: on its installation lap, Felipe Massa's car developed an electrical problem, which provoked a small fire that led to a long stop in the pits to effect repairs. Kimi Raikkonen's car also suffered a different electrical problem, which meant he too spent a long while in the garage.

Then, around lunchtime, a shower hit the track, which only started to dry after 3 in the afternoon today's technical programme was planned to include endurance testing, set-up work and development of new aerodynamic components.

The summary of the day in figures is as follows: 25 laps for Kimi (best time 1:23.215) and 29 for Felipe (1:23.077.) Testing continues at this circuit tomorrow, again with Raikkonen and Massa on track.
