Availability of the DRS system in China
The FIA have announced that drivers will only be able to use the Drag Reduction System on the back straight for the Chinese Grand Prix this weekend.
Being the longest straight of the year at 1170 metres though, they have also taken measures to restrain the system. Therefore, the zone for enabling the DRS system is 902 metres.
The rear wing device can now be activated several hundred metres after the long Turn 13. The detection zone – whether a car is within 1 second of the car ahead – is at the very start of the long right hander, Turn 12.
As usual, the DRS is free to use in practice and qualifying. However, it will be deactivated at any point during the weekend if the car using it is on intermediate or extreme wet tyres.
