Formula One makes its second appearance at the Buddh International Circuit which very quickly on its debut last year established itself with the drivers as a track to be savoured.

It has drawn comparisons with Spa-Francorchamps in Belgium, which has long been hailed as F1's best circuit given its fast, free-flowing, undulating nature.

Sebastian Vettel triumphed a year ago and a repeat for the 24-year-old German would make it four victories in a row this season, which would see him take a firm grip on the championship battle.
