Kimi Raikkonen set the pace ahead of Sebastian Vettel in Friday practice for the Formula One Chinese Grand Prix as the Ferrari pair dislodged the dominant Mercedes duo.
The Finn, a former winner for Ferrari in China, jumped to the top of the order with a one minute 36.896 second lap in Friday’s second practice session, beating German team mate Vettel by a margin of 0.109 seconds.
Championship leader Nico Rosberg was third for Mercedes, 0.237 seconds off Raikkonen’s benchmark.
Rosberg’s team mate and reigning world champion Lewis Hamilton, who heads into Saturday’s qualifying session with a five-place grid penalty for a change of gearbox, was fourth, 0.433 seconds adrift.
Rosberg had set the fastest time ahead of Hamilton in Friday morning’s interrupted opening session in which the Ferrari duo were only third and fifth.
But the Maranello-based squad turned the tables on their German rivals in the afternoon with their runs on the fastest, red-walled, super-soft compound tyre.
