This was the fourth and final day of the penultimate test of the winter. Inthe morning, Jaime did some aero evaluation runs and in the afternoon,the team tackled a race simulation. Over the whole day, the STR5completed the equivalent of over two race distances.

“That is encouragingon the reliability front,” said Chief Engineer, Laurent Mekies. “Even withthe rain interrupting our programme this week, it has been quite a usefultest, working on both dry and wet weather basic set-up. However, there isstill a fair amount of work to do before the first race in Bahrain and wehope to get a lot more testing miles under our belt, in Barcelona nextweek.”

Despite driving two Grands Prix today, our Spanish driver’s winter trainingprogramme seems to have paid off, as he seemed in fine form after thesession! “These past two days in the car have been successful and it wasgood that the weather improved, so I could manage to drive in the dry,”commented Jaime Alguersuari. “The most important aspect is that thecar ran reliably, which was our main target here in Jerez. It puts us ingood shape to tackle the final test in Barcelona.”
