Alonso leads second Interlagos practice

The Renault driver had a quiet session for most of the 90 minutes and his time of 1m12.314s went somewhat against the run of play.

For his part, Buemi made the most of what is clearly a competitive chassis as he came within 0.043s of his first fastest time in a free practice session.

The Swiss was quickest for most of the 90 minutes for the Toro Rosso team, with only world championship leader Jenson Button threatening his position by topping the list mid-session. That is until the Spanish double world champion changed all that.

Button ended the session fifth fastest overall behind team-mate and title rival Rubens Barrichello (third) and Red Bull's Mark Webber (fourth). Jarno Trulli was sixth for Toyota.

Sebastian Vettel took seventh in the second Red Bull in front of Nico Rosberg and Adrian Sutil. Lewis Hamilton completed the top ten.

Indeed, the entire field was covered by less than a second.

Buemi was quick from the outset, taking the top spot from Heikki Kovalainen with a 1m12.796s, before quickly lowering it to a 1m12.710s. Red Bull stablemate Sebastian Vettel had a crack at Buemi's time after 20 minutes, but was four thousandths shy of his time.

Then Button, having previously complained over the radio of having a combination of oversteer and understeer, suddenly went fastest with a 1m12.696s.

Two minutes later Mark Webber went quicker still, only for Button to respond immediately with a 1m12.523s lap.

At half distance it looked as though Button might go fastest in a practice session for the first time since the Spanish Grand Prix in May, only for Buemi to calmly emerge from the pits and take the top spot again with a 1m12.357s.

That seemed to settle the matter as the teams started cracking into their long run programmes. And that combined with a return of the drizzly weather we saw in P1 and Giancarlo Fisichella stalling his Ferrari at the end of the pitlane ensured that nothing much happened until the flurry of activity at the session.

That stirred up the order significantly with all the front-runners except Buemi posting last minute flyers.

The session proved fairly incident free with Vitantonio Liuzzi the only significant spinner at Laranja 20 minutes in.
