First DRS zone tweaked in India
23 October 2013 – The FIA has altered the DRS activation point into Turn 4 at the Buddh International Circuit, venue for this weekend's Indian Grand Prix.
Last season the activation point was 430 metres after Turn 3. However this year it will kick in at 350 metres. The detection point remains the same as in 2012, 16 metres before T3. The second DRS zone, onto the start-finish straight, meanwhile remains unchanged with the detection point 10 metres after Turn 15 and the activation point 36 metres after Turn 16.
