Championship rivals – and Brawn GP team-mates – Rubens Barrichello and Jenson Button topped the times as the F1 field took to the streets of Singapore for the opening free practice session of the weekend.
In a session that started as the sun set and ended in darkness, Barrichello managed to get ahead of Button to post the quickest time, with a lap of 1min 50.179secs enabling him to outpace the current points leader by just over a tenth of a second.
Button had looked set to top the times having run near the front throughout only for Barrichello to jump ahead in the closing moments of the session, with Red Bull's Mark Webber being the closest challengers to the Brawns in third place. Defending Singapore race winner Fernando Alonso was fourth with Sebastian Vettel and Heikki Kovalainen completing the top six.
Kovalainen was one of two drivers to run into problems during the session after the Finn suffered a spin early on on the dusty circuit, although he was able to keep his McLaren out of the wall. The same couldn't be said for Romain Grosjean however, who brought out the red flags when he clipped the wall with his Renault and suffered a spin – with the car coming to rest on the inside of the circuit.
Ironically, his incident came in the same place as the now infamous one that involved Nelson Piquet in last years race. Grosjean, who was declared fit to drive having been unwell on Thursday, was only able to manage nine laps on his first trip to Singapore and propped up the times as a result.
Elsewhere on the times, Lewis Hamilton was just behind team-mate Kovalainen in seventh, with Robert Kubica, Kimi Raikkonen and Kazuki Nakajima rounding out the top ten, the latter being the final driver to get within a second of Barrichello's benchmark.
On a circuit less suited to the Force India than either Spa or Monza, Adrian Sutil and Tonio Liuzzi had to settle for twelfth and 18th on the times, while Giancarlo Fisichella was more than two seconds off the pace and down in 17th.
