Red Bull restored the status quo on the Marina Bay Street Circuit on Friday evening as Sebastian Vettel and Mark Webber dominated the second free practice session for the 2013 Formula 1 Singtel Singapore Grand Prix. The German finished on 1m 44.249s, 0.604s faster than the Australian's 1m 44.853s, and a whole second up on Nico Rosberg as he lapped his Mercedes in 1m 45.258s with team mate Lewis Hamilton right behind on 1m 45.368s.
Romain Grosjean kept Lotus ahead of Ferrari with 1m 45.411s to Fernando Alonso's 1m 45.691s, despite the Frenchman suffering more technical problems on his E21, with Jenson Button taking an encouraging seventh for McLaren with 1m 45.754s ahead of Kimi Raikkonen in the second Lotus on 1m 45.778s.
Adrian Sutil made progress for Force India to take ninth on 1m 46.002s, narrowly ahead of Sergio Perez in the second McLaren on 1m 46.025s. Daniel Ricciardo was 11th for Toro Rosso on 1m 46.406s with team mate Jean-Eric Vergne right on his tail with 1m 46.429s despite two minor offs. Paul di Resta was next for Force India on 1m 46.606s, chased by the Saubers of Nico Hulkenberg and Esteban Gutierrez on 1m 46.808s and 1m 47.287s, as they sandwiched Felipe Massa's Ferrari in which the Brazilian recorded 1m 46.870s after brushing a wall.
Williams dropped down the order with 17th and 18th places, Valtteri Bottas on 1m 47.434s and Pastor Maldonado on 1m 47.761s. The Venezuelan damaged his FW35's front wing after going straight on in Turn 13 and had several further off-track moments.
Caterham asserted themselves over Marussia, but it was close. Giedo van der Garde headed the quartet on 1m 49.434s ahead of Charles Pic on 1m 49.526s, but Max Chilton was right there with 1m 49.619s ahead of Jules Bianchi on 1m 49.731s. (Formula1.com)
