Vettel stays fastest in final practice
21 September 2013 – Sebastian Vettel continued his pace-setting form during Saturday evening's third and final practice session for the Singapore Grand Prix. The Red Bull driver, who set a 1:44.173 on the Super Soft tyres, led Lotus rival Romain Grosjean by a reduced margin of 0.191 seconds, with Mercedes' Nico Rosberg in third.
As has traditionally been the case throughout the campaign so far, the majority of the final pre-qualifying session was dedicated to longer runs on the Prime compound tyre. Mark Webber was the driver in charge throughout this phase, recording a best effort of 1:46.220 to hold a narrow advantage over Red Bull team-mate Vettel.
But as the switch to the Super Soft rubber arrived in the final ten minutes, Vettel again stepped it up a gear, rounding the Marina Bay venue in a time of 1:44.173. His nearest rival was this time a lot closer, however, with Grosjean bouncing back from his Friday problems to get within two tenths of a second of the reigning triple World Champion.
Webber ultimately slipped to fourth, splitting the Mercedes duo of Nico Rosberg and Lewis Hamilton. Ferrari's Fernando Alonso followed in sixth, while Nico Hülkenberg put his Sauber between the McLarens of Sergio Pérez and Jenson Button for eighth.
Felipe Massa enjoyed a smoother session to break into the top ten for the first time this weekend, although future Ferrari replacement Kimi Räikkönen was unable to put together a representative time on the Super Softs and finished back in 12th position.
At the back of the field, Giedo van der Garde edged out Caterham team-mate Charles Pic, while Jules Bianchi finished nine tenths clear of Marussia colleague Max Chilton.
