After a break of 18 days, the end of the opening test in Jerez action resumed again in Bahrain today.
The twin four-day sessions at Sakhir represent the last chance for the teams to prepare for the Australian GP.
Mercedes drivers Nico Rosberg and Lewis Hamilton led the way in the first practice session for the Brazilian Grand Prix.
Rosberg set his fastest lap of 1:24.781 early in the damp 90-minute session and as conditions worsened, no driver was able to bump the German from the top spot. Hamilton finished the session 0.449 seconds off the pace in second.
Four-time World Champion Sebastian Vettel’s late surge bumped him into third, pushing Jenson Button and Fernando Alonso down into fourth and fifth, respectively. Vettel’s Red Bull teammate, Mark Webber, posted the sixth-quickest time.
Scuderia Toro Rosso boss Franz Tost is adamant that new signee Daniil Kvyat is the real deal, in the light of his good form in GP3 and F3 this year.
The Russian will start his learning process by driving in FP1 in Austin and Interlagos.
“We will have a test with him next week to get the Super License,” said Tost on Friday. “Afterwards, he will go out on Friday in America and in Sao Paulo, and of course we will have winter time, where he has to do a lot of work with physical training, mental training, then working on the simulator to prepare him as good as possible for the next season.”
