Yeah, completely unrestricted use.

However, with the experiments in twin zones, I can see Singapore having room for three.

One of the big challenges of the DRS allocations is that the FIA needs to allow for space for the detection software to work. That’s why Montreal didn’t have separate DRS zones, one on the back straight and one on the pit straight. There wasn’t enough space. However, Singapore would allow this, with three zones:

1) The first would be on the long back straight, along Raffles Boulevard. The detection point would probably go somewhere in between turns four and five.

2) The second would fit along the Esplanade Bridge, the long straight after the Singapore Sling. The detection point would probably be somewhere either side of the Sling itself, probably after it.

3) The third and final DRS zone would go on the main straight, with the detection point somwhere in the waterfront section, probably on the straight behind the grandstand or before the final corner.

I don’t quite agree with the 2nd point. What purpose would it do? Turn 10, then 11 and 12 are both tight one-line chicanes; no matter if you are 5 seconds faster than the car in front, there’s no room to run side by side, so you’re at best going to be a car length behind (nose to tail). Unless you can manage to force the guy to be on the defensive onto the hairpin of 13; I don’t see DRS doing much there. Kubica only JUST managed to overtake Buemi into T14 after cutting back from the T13 hairpin when his tyres were some 48 laps YOUNGER.

The pit straight one would also not do much other than help the following car keep up; there’s a load of dirty air to be had through the last corners.

That’s not the Esplanade Bridge. The Anderson Bridge is the bridge after the Singapore Sling. The cars then go around a tight left-hander and start heading north again. That’s the Esplanade Bridge. It’s the second-longest straight on the circuit.

Using this map as a reference, I’m talking about the space between T13 and T14. The detection point could be on the exit of T12; it wouldn’t be the first time we’ve had a detection point before a tight corner and the activation zone after it.

Yes, I know the one you’re talking about. Hence my T13/14 references as well above. Unless you have a massive run out of T12 you won’t really be able to get close enough for a move into T13; or force them on the defensive so that you can cut back/go around the outside of 13. I’m not convinced DRS alone will be able to create passing there given that T10/11/12 (2 chicanes in a row; which are tight 1-racing-line chicanes) will do a good job of separating the cars.

Haha I love the idea of 3 DRS zones at Singapore. Do it, I say. Although it might in some cases enable a driver who’s just been passed to stay with the leading car for a bit.

I wonder if it will ever get to a point of A passing B through DRS in zone 1, but B zaps back through in zone 2; and just ping pongs back and forth between the two

It served as a favourite overtaking place last year for Robert Kubica after he had a puncture and had to overtake slower cars on used primes, with him having new options. So it certainly is possible to overtake there if you have fresher tyres and it should be possible with DRS.

#

Kubica had fresh tyres while the overtakes were on tyres some 48 laps older

#
Enigma said 1 year, 9 months ago:

I know and I did say that, but I reckon it still shows it’s a good overtaking spot, as he did most of the overtaking there. It’s certainly not as good as the Radillion straight in Spa, but it’s one of the best on the track and with DRS it could work.

#
raymondu999 said 1 year, 9 months ago:

I remember he made 2 passes there; but I remember the others were made at different spot; I still stand by my view that T5-T7 is a much better spot for DRS

#
Enigma said 1 year, 9 months ago:

He actually made three passes.

I agree that T7 is better for overtaking, I’m just saying it’s very much possible between turns 13 and 14 as well.

#
raymondu999 said 1 year, 9 months ago:

Yes it’s possible; but I fear that you would need to be a WHOLE lot quicker than the other car to actually make it stick into there.

#
Enigma said 1 year, 9 months ago:

Apparently there’ll only be one DRS zone between 5 and 7.

Oh? Source?

Peter Windsor is tweeting it: “One DRS zone for the Singapore GP: detection is 230m before Turn 5; activation is 35m after geometrical apex of Turn 5.”
