The battle to carry the Lamborghini Temerario GT3 as much as tempo with the remainder of the DTM subject following the Spielberg debacle continues on the second spherical in Zandvoort. The Italian model made a concerted effort forward of the weekend within the Netherlands to be allowed to run a unique rear wing setting with a view to generate extra downforce.
This requires a minor modification to the rear wing mounting. The matter was debated inside the DTM GT Committee alongside the opposite producers, because the steeper wing setting falls exterior the automotive’s official FIA GT3 homologation. Nonetheless, it may be authorized by means of the “DTM Extra Homologation”.
This regulatory software was initially launched a yr in the past to shut grey areas within the FIA homologation. The talk sparked important pushback from the producers represented within the DTM. In accordance with sources, Ferrari specifically fought the transfer tooth and nail, whereas BMW, Mercedes-AMG, and McLaren are additionally mentioned to view the matter critically. Different producers abstained from the dialogue.
How the change was pushed by means of regardless of resistance
Because the DTM GT Committee – consisting of Michael Rebhan (Head of DTM Sporting and Occasions), Technical Coordinator Robert Maas, and Collection Supervisor Michael Cap – decides by easy majority, the change was authorized nonetheless.
In consequence, a revision to the Stability of Efficiency (BoP) initially printed final Friday was despatched out on Thursday night forward of the Zandvoort weekend. It grants the Lamborghini not solely a rear wing that’s three levels steeper but additionally 0.02 bar extra enhance stress within the higher rev vary.
This adjustment is because of the truth that the automotive is now slower on the straights due to the steeper rear wing. Concerning enhance stress, the automotive was already working exterior the window supposed by the FIA throughout homologation, however the further “enhance” is technically possible and is subsequently being carried out.
Enhance stress strikes exterior FIA homologation
“The upper enhance stress ought to assist us, and we have now additionally made a couple of steps ahead,” says Staff Principal Gottfried Grasser, who’s concentrating on positions within the midfield. “The excessive temperatures must also have a constructive impact by way of getting the tires into the window higher.”
Generally, the Lamborghini has as much as 0.1 bar extra enhance within the excessive rev vary than it did in Spielberg, the place it was already on the higher restrict of the FIA window.
Nonetheless, the BoP for Zandvoort is hardly akin to Spielberg anyway, because the observe traits within the Netherlands – with its many medium-speed corners and important elevation adjustments (Spielberg sits at almost 700 meters, Zandvoort at sea degree) – are utterly completely different.
Why the Zandvoort BoP is just not akin to Spielberg
For that reason, the SRO Motorsports Group, which is accountable for the classification, used the second DTM check in Vallelunga on the finish of March because the BoP baseline. Final yr’s information from Zandvoort is just about unusable as a result of new DTM-spec tire and adjustments to the automobiles.
This additionally explains the numerous adjustments in comparison with Spielberg. Notably, the McLaren should make do with considerably much less enhance stress – not solely in comparison with Spielberg but additionally in comparison with Zandvoort 2025. Within the low to medium rev vary round 5,500 rpm, the discount is 0.06 bar, bringing the classification extra consistent with the values usually seen in SRO-run sequence.
In precept, Zandvoort ought to swimsuit the McLaren 720S GT3 Evo, because the automotive’s conventional battle to generate tire temperature must be offset by the abrasive asphalt.
The favorable climate forecast can also be anticipated to have a constructive influence. Moreover, the McLaren notoriously dislikes excessive curbs, that are non-existent in Zandvoort. It stays to be seen whether or not these elements will compensate for the much less favorable BoP.
