The FIA has confirmed that the Singapore Grand Prix this weekend will feature a single DRS zone rather than the two used for the Italian Grand Prix at Monza.

The detection zone will be based at turn four with the activation zone then being placed on the exit of turn five ahead of the longest straight on the street circuit.

Overtaking in Singapore has been far from easy so far in the races held on the street circuit, with the hope that DRS will have a positive impact on the racing.

The DRS zone will come to an end just before turn seven, which is seen as the best overtaking place on the circuit and was the scene of a clash last year between Lewis Hamilton and Mark Webber while the pair battled for position.

'Singapore DRS zone from turn 4 along bumpy straight down to T5 where Hamilton + Webber tripped over each other last year. Will be wild there,' tweeted BBC F1 commentator Martin Brundle.

McLaren-Mercedes team principal Martin Whitmarsh, meanwhile, has predicted an 'electrifying' grand prix in-store with the addition of DRS in Singapore for the first time

"Luckily, we have two drivers who are never satisfied to sit behind another car, but we should expect some truly electrifying racing this weekend," the Englishman contended. "The track is wide enough to support close and exciting wheel-to-wheel racing, and I sincerely hope that's what we see."

There have been five safety car appearances in the three Singapore Grands Prix to-date.
