Lewis Hamilton completed his fourth day of pre-season testing today at the Circuit de Catalunya in cold and wet conditions. His mileage today of 242 km takes his total to 1513 km with the new F1 W04.

The morning programme focused on making the most of opportunities for dry running before the rain began in earnest. In the wet conditions in the afternoon, the team focused on systems checks and tyre evaluations.

Testing will resume at the Circuit de Catalunya on Thursday 28 February for the final pre-season test of 2013.

Lewis Hamilton: "The conditions today meant that we didn't complete as many laps we would have done in the dry but we have gone through the test items that we wanted to achieve this week.

We have been working on our consistency over long runs and we managed one run this morning on dry tyres; the car felt okay but the conditions were also very cool, so we cannot draw too many conclusions.

Like I said in Jerez, I can feel that we have a good foundation with this car but there is still a lot to learn and we know that the name of the game is to improve our downforce.

From a personal point of view, my relationship with the team is growing all the time and it's going really well. I'm happy working with the guys, we are working in the right direction together and I'm pushing to extract the most from the team, just like they are with me."

Ross Brawn: "Overall, we've had a good week in Barcelona and achieved the programme that we set ourselves for this second test. The rain today was a little unfortunate; however we made the best of the conditions and were still able to take some useful data out of the day.

Nico and Lewis are becoming more familiar with the car and its behaviour as each day progresses, and Lewis is settling into the team very well.

Both drivers are providing excellent feedback which is pushing the development of the car both here and at the factory, and it is very rewarding to see their enthusiasm and commitment.

We now have just four days of testing left until the first race in Australia, and a lot of work will be done before we return to Barcelona next week."
