Chinese Grand Prix (2013) RESULT

Qualifying for the 2013 Chinese Grand Prix produced a fascinating grid, with three former world champions at the front on soft tyres, two more world champions lurking down the grid on mediums – hoping a different strategy would see them rise to the top – and Red Bull’s Mark Webber starting from the pit lane after running out of fuel in qualifying.

Alonso had a cracking start, overtaking Raikkonen for second place at the start and taking Hamilton for the lead by lap five, but stopped two laps later to change his softs for mediums and coming out behind Vettel and Button, who had started on mediums, and Hulkenberg.
