Formula One: Red Bulls top practice time sheets at SingTel Singapore Grand Prix

RED Bull set the Marina Bay Street Circuit alight on Friday night by threatening to rewrite the lap record for the SingTel Singapore Grand Prix.

Germany's Sebastian Vettel topped the time sheets in Practice 2 with a sizzling 1min 44.249sec effort. His team-mate Mark Webber of Australia was 0.604sec behind.

The lap record of 1:45.599, set in the first edition of the iconic night race in 2008, is held by Finland's Kimi Raikkonen, back when the Lotus driver was employed by Ferrari.

Mercedes' Nico Rosberg was third on 1:45.258 while team-mate Lewis Hamilton, who had topped P1, was on 1:45.368.

Said Vettel: "It was quite busy; it's pretty hot out there, good fun and a nice place, but for all of us it's quite hard work. The time we set was a surprise today, I got a good lap in, but I don't think it's completely representative. We seem to be quick, but I think Mercedes will be very strong in qualifying tomorrow. I think Turn 10 is the best solution we have with the space that's available."

Webber added: "We got most of the work done today that we planned to. It's an easy venue to not get what you want, but in the end I think we've got a reasonable set-up. We've got work to do on the long run and also on the short run, you can't neglect that. We won't count our chickens yet, but it was a smooth day. Turn 10 is better now I think."
