The FIA has confirmed that there will be one DRS zone at Interlagos this weekend for the 2012 world championship finale.

As in 2011, the activation zone is on the back straight leading from Curva do Sol (Turn 3) to Descida do Lago (Turn 4), with the detection zone at the apex of Turn 2.

Changes to the circuit ahead of this year's race include the installation of new debris fences on both sides of the track between turns 3 and 4, while a kerb has been installed on the apex of turn 15. Tube inserts have also been placed in the tyre barrier at the end of the wall at the pit entry.

The stewards this weekend include eight times Le Mans winner Tom Kristensen, who also enjoyed success in the German F3 championship (1991), the Japanese F3 championship (1993) and was ALMS champion in 2001.

A popular and respected figure, this year he has competed in the inaugural FIA World Endurance Championship, driving for Audi Sport Team Joest. Along with long-time team mates Dindo Capello and Allan McNish he won the first round of the championship at the 12 Hours of Sebring, making him the first man to win the race six times.

He is joined by Garry Connelly, Deputy President, FIA Institute, Australian Institute of Motor Sport Safety, F1 and WTCC Steward and World Motor Sport Council member and Silvia Bellot a graduate of the FIA Trainee Steward Programme.
