Q: Passage: In the second qualifying session, every driver set a lap on the option tyres except two. Lewis Hamilton still managed to take his McLaren into Q3 with the sixth fastest Q2 time on the prime tyres, and Pastor Maldonado, who did not set a timed lap. It was notable that Red Bull Racing and Ferrari needed to use options when Hamilton could use primes. Jaime Alguersuari – a man who had come from far back to score points a few times in , like his teammate did at this weekend set the slowest Q2 time and dropped out on the same row as Rubens Barrichello's Williams. Neither Renault made the top 10, Vitaly Petrov in 12th and Nick Heidfeld in 14th. One Force India and one Sauber failed to make the cut – Kamui Kobayashi (13th) joined Heidfeld on row 7, and similarly Paul di Resta just missed out with 11th.
