Kimi Raikkonen set the fastest time of the week at the Circuito de Jerez, with Sebastian Vettel also top of the standings on the first two days. Despite such encouraging pace from Ferrari - as well as impressive mileage - Arrivabene is refusing to get carried away by the strong start as he feels Mercedes has yet to show the performance it is capable of.
“If one makes a comparison to last year, these past few days of testing have produced encouraging signs,” Arrivabene said. “The team has worked well, both at home and at the track and our drivers did a great job, providing the engineers with valuable feedback.
“But above all, I am pleased that the group has rediscovered its motivation and team spirit. In terms of performance, I don’t think our competitors – one in particular – have shown their true potential over these past days. I think we will only discover the truth about them and about ourselves at the last Barcelona test session.”
The second pre-season test runs from February 19-22, while the final test takes place from February 26-March 1.
