Sebastian Vettel beat Red Bull teammate Mark Webber to the fastest time in Friday’s second Singapore Grand Prix practice session after a mighty battle between the duo.
Championship leader Vettel and Webber swapped the top spot repeatedly on the soft-compound tires early on. Webber won that battle, with a time of 1m46.157s giving him a 0.251-second advantage over the German, who had just usurped his original mark.
Vettel blew that pace away when he moved onto super-softs and lapped in 1m44.249s. Webber’s response was compromised by a firm clout of the wall near the end of the lap, leaving him 0.604sec down in the end.
Third-placed Nico Rosberg, who pipped Mercedes team-mate Lewis Hamilton by 0.11sec, was a second off Vettel’s pace. Steering and brake issues again limited Romain Grosjean’s mileage, but did not stop him putting his Lotus fifth, just 0.043sec behind Hamilton, during what little running he managed. That placed him ahead of Fernando Alonso and Jenson Button in the top Ferrari and McLaren respectively, and Kimi Raikkonen in the second Lotus. Adrian Sutil and Sergio Perez completed the top 10.
Bar minor brushes such as Webber’s, everyone managed to stay away from the barriers with the exception of Pastor Maldonado, whose Williams required a new front wing.
