F1 Grand Prix, GP China, Shanghai International Ciruit

During the first free practice session of the Chinese Grand Prix it immediately shows that the McLaren Mercedes F1 Team is using a different diffuser than before. Lewis Hamilton surprisingly was the fastest man on track followed by the Brawn GP duo Jenson Button and Rubens Barrichello. The updates on the MP4-24 really help the Woking-based outfit as Heikki Kovalainen was fourth.
