Rising temperatures and an all-nighter played into Red Bull's hands in Saturday's final practice in Hungary where Seb Vettel set the pace
After finishing half a second behind McLaren's Lewis Hamilton in Practice Two, Red Bull opted to use one of their curfew exceptions on Friday night.
And the extra hours, coupled with rising temperatures, paid off with Vettel setting the pace on Saturday morning.
The reigning World Champ clocked a 1:21.168 to finish 0.301s ahead of Ferrari's Fernando Alonso.
Jenson Button was third quickest.
Report: A warm start to the day with the track temperature already at 32'C as final practice got underway with Tonio Liuzzi leading the field out for their installation laps. Jerome D'Ambrosio posted the morning's first time, a 1:32.884.
The Virgin driver, though, was soon dropped as Nico Rosberg hit the front followed by Jenson Button. Michael Schumacher went third quickest. With the track rubbering up, more drivers ventured out including reigning World Champ Sebastian Vettel. However, he could only manage 17th place on his first lap.
The German went on to lead the way with a 1:22.021 while his team-mate Mark Webber took second place ahead of Lewis Hamilton. Problems for Rosberg, who climbed out of his car while his team worked on something around his seat area.
Halfway through the session it was Vettel leading with a 1:22.021, followed by Hamilton, Webber, Buton, Massa, Rosberg, Schumacher and Alonso.
Alonso improved to fourth place before being dropped as Rosberg, with his seat now sorted, climbed to second. Schumacher moved ahead of Massa and Vettel struggled to stay on the track. However, he wasn't the only one as several drivers ran wide, although with plenty of run-off area there were no accidents.
The final ten minutes saw the drivers take a run on the super soft tyres. Alonso jumped into the P1 slot, Massa took second place and then ran off the track on his next lap, Hamilton got it wrong at the first corner, Button didn't do much better on his out-lap, Jaime Alguersuari ran it wide, Button improved to second and Vettel hit the front with a 1:21.169.
