As Ferrari drifted through 2014 with poor results, massive changes were under way at Maranello.
While the overhaul of team management was perhaps most significant to the resurgence that followed, Ferrari has also made a step change in its car design, this year's car being significantly different to its predecessors.
It now seems the team's internal structure has allowed the different technical departments to work in unison, and that a big factor in the improved 2015 form is that the power unit and chassis are both integrated and complementary to a far greater degree than in 2014.
