Fourth and final day of testing for Scuderia Ferrari Marlboro and ten other Formula 1 teams all working at the Jerez de la Frontera circuit in southern Spain.

Once again today, Fernando Alonso was at the wheel of the F150th Italia. The Spanish driver worked on a comparison of various set-up options to suit the Pirelli tyres. Today, as over the past days, the car was able to run pretty much constantly: once again there were over 100 laps completed (115 to be precise) with a best time of 1.21.074. It was not until the very last minutes of the day that a rain shower hit the track, which meant the wet weather tyres could be used for the very first time.

With this second test session over, preparations for the start of the 2011 World Championship resume on Friday 18 February at the Catalunya circuit, on the outskirts of Barcelona. The first to take to the track for Scuderia Ferrari Marlboro will be Fernando Alonso, running on the opening two days, with Felipe Massa taking over for the final two.
