Ferrari takes one-two in final practice

Felipe Massa topped the session by 0.082 seconds over team-mate Kimi Raikkonen, with championship leader Jenson Button third for Brawn, nearly half a second down on Raikkonen's time.

Rubens Barrichello was right behind his team-mate in the second Brawn, with Robert Kubica completing the top five for BMW.

The Ferraris led the way for much of the hour, with Massa and Raikkonen usurping early pace-setter Fernando Alonso (Renault) to hold a one-two by the halfway point.

Barrichello put Brawn to the front after 41 minutes, albeit only briefly before Massa retook the position for Ferrari.

At that stage all the frontrunners were still on hard tyres, but in the final 14 minutes the qualifying-style runs began in earnest, with Toyota's Timo Glock the first to bolt on a set of softs and jump to the front 14 minutes from the end.

His 1m21.377s was totally eclipsed when Massa tried softs, though, as the 2007 race winner produced a 1m20.553s on his final run.

Even the Brawns could not match that, and Raikkonen then emphasised Ferrari's pace by returning to second place - initially 0.3s behind Massa before closing the gap to less than a tenth of a second.

Behind the Ferraris, Brawns and Kubica, Toyota duo Jarno Trulli and Glock were sixth and eighth, split by Lewis Hamilton's McLaren.

Sebastien Buemi put the revised Toro Rosso in the top ten again in ninth ahead of local hero Alonso.

Friday afternoon pace-setter Nico Rosberg was only 12th, having had a brief trip off the road at Campsa in his Williams.

It was a low-key session for Red Bull too, with Mark Webber and Sebastian Vettel back in 13th and 16th positions.

Nick Heidfeld sat out the second half of the session after crashing his BMW at Turn 12. The left front corner was heavily damaged, leaving Heidfeld at the bottom of the times once everyone else had switched to qualifying simulations.

Force India's Giancarlo Fisichella had a less dramatic incident, spinning out of Turn 7 but rejoining unscathed after a visit to the grass.
