Kimi would quickly return to the track as Sutil moved into sixth, 1m:34.049, on what was most likely a practice qualifying run. Massa would pit, joined by Coulthard. Raikkonen would also return to his pit.

Bourdais was now fifth, 1m:33.978. Nico had pitted briefly and would be the only driver on the track out of the top sixteen.

Team-mate Barrichello would move ahead and into third, 1m:33.551. Vettel was now fifth, 1m:33.674, after his qualifying run. Raikkonen was out on the track joined by Nico.
