Jaime Alguersuari was in the STR6 as Toro Rosso completed their fifteenth and final day of pre-season testing in Barcelona.
The Spaniard completed 72 laps and finished the day as the seventh fastest driver.
“Overall, these final four days [in Barcelona] have been productive,” said Chief Engineer, Laurent Mekies. “We did a lot of laps, including a couple of full race simulations and we practiced pit stops extensively.
“Compared to the first three tests, we also acquired much more data regarding tyre performance and degradation, given that we did many more long runs with high fuel loads. Now, we must wait until Melbourne to see the true level of our performance.”
Looking back over the entire pre-season testing period, Alguersuari thinks that the team are in good shape as they head towards the new season.
“I would sum up all of the pre-season testing as reasonably positive for our team,” he said. “We have learned a lot about the new parameters we have from this year's rules and obviously understanding the new Pirelli tyres has been an important element of these tests.
“It has been very different to the previous year, so now we start a new championship in Melbourne, with a new philosophy. I think we have a good car, which shows potential. However, we still need to improve a lot and that will involve plenty of hard work in the coming weeks.”
