Lewis Hamilton set the pace in the final practice session at the Abu Dhabi Grand Prix as Sebastian Vettel's Red Bull suffered brake problems.
The Lotuses of Kimi Raikkonen and Romain Grosjean set the pace early on before Hamilton went out and shot straight to the top of the leaderboard.
He was soon joined by McLaren teammate Jenson Button in second before Mark Webber completed the top three as the session drew to a close.
Vettel didn't set a hot lap until the final moments because of a brake problem but did manage to usurp teammate Webber in third with his final attempt at the Yas Marina circuit.
Vettel's world championship challenger Fernando Alonso was eighth fastest.
Qualifying for tomorrow's race takes place later this afternoon.
