Sebastian Vettel refused to release his grasp on the top spot in the second practice session in Shanghai.
He set a quickest time of 1’37.688 on his second quick run on soft tyres.
That was one tenth of a second faster than Lewis Hamilton’s first run on the same tyres.
Jenson Button was third-fastest but looked able to go quicker, before he was held up by Jaime Alguersuari.
The Mercedes of Nico Rosberg and Michael Schumacher were foutrh and fifth ahead of Felipe Massa’s Ferrari.
An hydraulic problem kept Fernando Alonso in the pits for part of the session. He was able to get out later in the session but was held up by both HRTs.
For the second session row Nick Heidfeld hit a barrier. This time he ran wide at the first corner and skidded, running nose-first into the barrier at low speed.
Slowly he was able to extract the Renault from the barrier and drag it to an escape road where he was recovered, and returned to the track later in the session.
Paul di Resta was unable to run due to a fuel pressure problem. HRT’s Vitantonio Liuzzi also missed a large amount of the session.
