» Two DRS zones at Singapore

The FIA has confirmed that the Marina Bay street circuit will feature two DRS zones for this weekend’s Singapore Grand Prix, continuing the trend seen at almost every Grand Prix this year.

The existing DRS zone between Turns 5 and 7 – known as Raffles Boulevard – will remain in place, with its activation zone placed at the approach to Turn 4.

However, the sport’s governing body has opted to add a second DRS zone along the track’s start/finish straight, with the detection point being placed at the 24-turn circuit’s penultimate corner.

Another major change to the circuit is the reprofiling of the unpopular ‘Singapore Sling’ chicane at Turn 10, which has been removed completely and replaced with a conventional left-hand turn. The corner witnessed several accidents over preceding Singapore Grands Prix, triggered by drivers being too aggressive over the kerbs.

The change is estimated to improve overall lap speeds by over one second, giving the event a greater chance of running its full race distance instead of being limited to a two-hour maximum duration.

The 2013 event will mark the sixth running of Formula 1’s only night race, with the first free practice session to get underway at 6:00pm local time.
