Brawn GP driver Jenson Button has set the fastest time in final practice ahead of qualifying for the Abu Dhabi Grand Prix.
The new world champion's time of 1 minute, 40.625 seconds around the Yas Marina circuit was a mere two thousandths of a second quicker than British compatriot Lewis Hamilton of McLaren.
Button's Brawn GP teammate Rubens Barrichello was third fastest, ahead of Toro Rosso's Sebastien Buemi.
The BMW Saubers of Nick Heidfeld and Robert Kubica were fifth and eighth on the timesheets, separated by McLaren's Heikki Kovalainen and Toyota's Jarno Trulli.
