This years Indian Grand Prix will feature an extended DRS zone following feedback from the inaugural race last season that the area was ineffective.
The 2011 race featured just a handful of overtakes as Sebastian Vettel roared to victory and the FIA are keen to resolve this. The first zone along the main start/finish will remain the same, but the second zone has been extended by 80 metres between turns three and four.
The zones will also be fully independent of one another with two detection areas.
