The FIA has announced the DRS zone for the Chinese Grand Prix, allocating a section of the back straight between turns 13 and 14.

The straight is the second longest in Formula One, and in order to prevent overtaking becoming too easy, drivers will not be allowed to activate the DRS until a point that is 0.56 miles from turn 14, while the full length of the straight is actually 0.73 miles. The detection point to measure the gap between drivers is located in turn 12.

After plenty of overtaking in Malaysia, drivers are expecting to see a lot of position changes once again due to the layout in China, and Paul di Resta said it was likely to be one of the most conducive tracks for the system.

"It will be interesting to see how the DRS activation works with the rear wing in Shanghai because if it's going to work anywhere that's where it will be because it has a very long straight," Di Resta said.

Renault technical director James Allison had previously warned that the FIA should not allow drivers to use the full length of the straight in China, saying that the zone in Malaysia had been well selected.

"It was good to see lots of overtaking and I think the FIA got the DRS settings just about right in Sepang," Allison said. "For China, they will need to choose the DRS activation point carefully because the DRS straight is around three hundred metres longer compared to Sepang."
