Kimi Raikkonen leads Ferrari one-two in Chinese GP Friday practice
Kimi Raikkonen spearheaded a Ferrari one-two in second practice for Formula 1’s Chinese Grand Prix.
The Finn clocked a 1m36.896s on the super-soft tyres to finish one tenth of a second clear of team-mate Sebastian Vettel.
Nico Rosberg, who set the pace in first practice, was third quickest, 0.237s adrift, with Mercedes team-mate Lewis Hamilton two tenths further back in fourth.
After a morning session made disjointed by two red flags, second practice at Shanghai proved to be a smoother affair.
Rosberg, who suffered an ignition problem right at the end of practice one, was the first of the frontrunners to bolt on the super-softs and set the early pace but he was subsequently deposed by Vettel before Raikkonen went quickest.
Attention then turned to long runs in preparation for Sunday’s race, with Mercedes splitting its strategy by putting Rosberg on the softs and Hamilton on the mediums.
In contrast, Ferrari pair Raikkonen and Vettel ran long stints on the super-softs.
Daniel Ricciardo, whose Red Bull sported a heavy coating of flow-vis paint midway through the session, was best of the rest in fifth ahead of Max Verstappen and Nico Hulkenberg.
Carlos Sainz Jr, Sergio Perez and Valtteri Bottas completed the top 10.
Fernando Alonso, who was cleared to compete in the remainder of the grand prix weekend in between sessions, was 11th quickest, one tenth quicker than McLaren team-mate Jenson Button.
Felipe Massa made up for lost running in practice one, following two tyre failures, with 34 laps, and the 14th fastest time.
Pascal Wehrlein continued to impress, ending the session 17th ahead of both Saubers and his Manor team-mate Rio Haryanto.
It was another frustrating session for Esteban Gutierrez, who suffered electrical problems in first practice and then was confined to the garage for most of second practice after his rear brakes caught fire.
Kevin Magnussen did not take part in the session as Renault continued its investigation into the issues he suffered in the opening session that resulted in a dramatic failure on the left rear of his car.

Nico Rosberg fastest as failures disrupt Chinese GP practice
Nico Rosberg edged Mercedes Formula 1 team-mate Lewis Hamilton to the quickest time in first practice for the Chinese Grand Prix as running was limited because of two red flags.
Championship leader Rosberg clocked a 1m38.037s on the softs to finish 0.146 seconds clear of Hamilton with Ferrari’s Sebastian Vettel just under half a second further back in third.
Race control brought out the red flag early in the session when Felipe Massa spun at Turn 6, dragging gravel onto track.
Replays showed the left rear tyre appeared to come away from its rim, pitching the Brazilian into a spin.
Massa recovered to the pits and headed back out later in the session, but the left rear deflated again.
Pirelli said investigations on both failures showed no sign of a puncture.
The session was red-flagged for a second time to clear substantial debris following a left-rear tyre deflation for Renault’s Kevin Magnussen.
The Dane was warned by his team of a possible brake problem before Magnussen reported the rear suspension was broken.
Hamilton set the early pace on the medium tyres, two tenths quicker than his team-mate Rosberg.
However, Hamilton spun twice at the same corner with the Briton reporting: "Something is up, I keep having this locking into Turn 11".
In the closing stages of the session, Rosberg told Mercedes he was in "limp home mode" with the team telling him he might have "an engine issue".
Teams lost around 30 minutes during the second red flag as a comprehensive track inspection was carried out amid suggestions debris had triggered Magnussen’s puncture.
There was a flurry of activity when the session restarted with eight minutes to go, during which Rosberg edged ahead of Hamilton and Vettel put his Ferrari third.
Red Bull’s Daniel Ricciardo was fourth quickest ahead of Kimi Raikkonen, Daniil Kvyat and Carlos Sainz Jr.
McLaren brought seven sets of the super-soft tyre to Shanghai and decided to make use of the rubber early in the weekend, with Jenson Button ending the session eighth, 1.9s off the pace.
Force India’s Nico Hulkenberg and Toro Rosso’s Max Verstappen completed the top 10.
