Interlagos adds grooves to track surface to help drainage

Brazilian Grand Prix organisers have undertaken a few changes to the Interlagos circuit in order to improve safety in the event of a wet-weather race.

Following recommendations from the FIA, grooves have been inserted into the track's surface in several areas to help drainage, the venue having often seen rain affect proceedings in the past.

Six corners have received changes destined to alleviate issues should wet conditions prevail this weekend.

"The apex areas of turns 2 and 12 have been resurfaced," wrote FIA race director Charlie Whiting in a note to the teams.

"Additional grooving of the track has been carried out in places where water was accumulating the most during the race last year, notably in turns 2, 3, 12, 13, 14 and 15.

"In order to ensure that the grip of the track is more consistent it has been cleaned twice with very high pressure water."

Organizers have also added 'sausage kerbs' behind the apex of existing kerbs at turns 2,4,8 and 10.
