Fernando Alonso has insisted that there is still room for improvement in the F2012 - even after setting the fastest time on the fourth and final day of the Jerez test.
After a modest opening three days to the winter, the new Ferrari finally flexed its muscles early on Friday morning as Fernando registered the second-quickest time of the week, an eye-catching and table-topping 1:18.877.
The result left the Spaniard in a positive mood as he reflected on the week - even though another technical glitch limited his Friday running to just 39 laps.
"We learned a lot about the difference of the car [compared to last year's], it's been a learning test for us, a lot of constant speeds for us to do the aero and mechanical tests," the former World Champion toldSky Sports News.
"Overall, it has been a positive four days for us and understanding the car. But obviously with a completely new concept and a completely new design there is a lot of room for improvement for us and that's what we need to focus on in the next couple of tests."
