Drivers have expressed their shock {that a} fourth DRS zone has not been added on the revised again straight amid issues over an absence of overtaking on the Marina Bay circuit.
A structure change is owed to building work across the remaining sector, which has led to the attribute 90-degree Turns 16-19 being changed by an extended straight with a high-speed kink.
Drivers plan to use the Friday briefing to lobby the FIA for an additional DRS zone, however any trial for FP1 is extraordinarily unlikely to be given the inexperienced mild because of security issues over its last-minute nature.
Nevertheless, the FIA has mentioned that it was initially prepared to embrace adjustments to the configuration however that there was no “clear consensus” when groups had been consulted upfront of this weekend’s race.
A press release provided to Autosport learn: “We cannot be assessing any further DRS zones for the Singapore Grand Prix.
“It’s one thing that was thought-about following the change in structure for this 12 months, and the FIA contacted all the groups a number of weeks in the past to ask for his or her suggestions and enter.
“There was, nevertheless, no clear consensus from these groups that responded and, following our security simulations, it was determined that we would not take the matter any additional.”
Autosport understands that not all groups responded to the governing physique and that the session interval started months upfront.

Esteban Ocon supposed that simulations of the circuit might need misrepresented the severity of a bump within the observe floor, with the Flip 15 kink additionally a consider omitting one other DRS zone.
The Alpine racer reasoned: “The FIA is worried about security in that little left kink. I reckon personally, and the opposite drivers too, that it isn’t going to be a problem.
“We’re pushing in the intervening time to have the ability to attempt it at the very least in FP1, see the way it feels and if it is OK, probably preserve it. There is no motive why we might not have the ability to preserve it.
“Within the simulator, there was an enormous bump on that left kink, which might be the reason for not having it. However I do not suppose it’s there in actual life.
“I reckon that is a problem from scanning with the partitions being there and it is quick and all that.
“However even when we wish to be actually secure, we simply put [the DRS zone after the T15 kink].
“We’re going to be in fifth gear, so actually the drag impact comes after that kink so we will put it after.”
