Kimi Raikkonen led the way in FP in Singapore Grand Prix, pipping Lewis Hamilton by just 11 thousandths of a second to the top time. But the other Ferrari only covered a dozen laps following a brush with a barrier.
During his qualifying simulation run Sebastian Vettel was on course to improve his time when he bounced off the wall at the exit of turn 21. He immediately pitted and Ferrari began investigating his car’s radiators intensely.
He never rejoined the track, meaning he missed his only chance to run a race simulation in representative track conditions.
The Red Bull drivers couldn’t get within half a second of either of them, though not for a lack of trying. Max Verstappen reported a loss of power on his car which the team had difficulty tracing.
Valtteri Bottas was fifth-quickest after a near-miss with the wall at the final corner when he ran wide at the end of a flying lap.
Renault again put in a good account of themselves, Carlos Sainz Jnr leading the midfield and Nico Hulkenberg also squeezing into the top 10. They were separated by Romain Grosjean, Fernando Alonso and the delayed Vettel.
Marcus Ericsson was the quicker of the Sauber drivers in 12th despite a brief spin. The Williams pair were last, Lance Stroll forced to pit with a right-rear brake fire at one stage.
FP2 CLASSIFICATION (90/90 MINS)
