Sebastian Vettel gave himself the best possible chance of adding the inaugural Indian Grand Prix trophy to his collection by taking yet another Formula One pole position on Saturday. It was a typically dominant performance from Red Bull Racing’s Vettel — who has already clinched the 2011 World Championship — on a circuit made tricky by the dusty conditions, but in the end he posted the fastest lap by the healthy margin of 0.3 second ahead of his nearest rival, McLarens Lewis Hamilton.
