Was the criticism of the Lamborghini Temerario GT3 untimely? After the catastrophic begin in Spielberg, the place the Lamborghini drivers languished behind the pack, Abt driver Luca Engstler managed an eighth and a sixth place at Zandvoort. “It may well’t be such a handful if we’re on the second row,” Lamborghini manufacturing facility driver Engstler defended his automotive on Sunday at ran.de after a powerful third place on the grid.
However what position did the DTM extra homologation play on this upward development, which allowed the Lamborghini groups for the primary time to run with a rear wing configuration not homologated by the FIA? “It is a mixture of issues, however after all the rear wing helps us,” clarified workforce principal Gottfried Grasser.
“The downforce from the rear wing primarily helps with driveability, as a result of you may push extra on the nook entry and the automotive is best to drive in that space. It additionally makes it a bit simpler to arrange the automotive,” he defined.
The specifics of the Lamborghini particular regulation
What modified for the Temerario GT3 via the extra homologation? Shortly earlier than the DTM weekend at Zandvoort, the DTM GT Committee determined that the Lamborghini groups Grasser and Abt – regardless of opposition from different producers producer pushback, the DTM accepted a particular answer for Lamborghini – could be allowed to run a rear wing setting that generates extra downforce and isn’t lined by the automotive’s FIA homologation.
Within the up to date Stability of Efficiency (BoP), it acknowledged that the rear wing may very well be set three levels steeper. This meant the minimal allowed angle of assault was not 5, however eight levels.
This is able to not have been doable and not using a {hardware} change: With the assistance of the DTM extra homologation, the utmost achievable angle of assault was elevated from seven to 12 levels, enabled by a brand new bracket. That is the connecting piece between the L-mount, which is mounted to the chassis, and the rear wing blade.
Steeper rear wing than beforehand doable even at Monza
From the skin, the distinction is barely seen, as solely the mount was barely adjusted and the rear wing is now set steeper than previously. How desperately the Temerario wanted the change was evident throughout the GT World Problem Europe weekend at Monza, the place the automotive was additionally allowed to make use of the change because of SRO extra homologation.
As a result of even on the high-speed monitor, the Temerario headed out with an angle of assault of eight levels – one thing that may not have been doable with the FIA homologation.
Abt examined with particular answer earlier than Zandvoort
Whereas the Grasser workforce ran the modified configuration for the primary time throughout DTM free apply at Zandvoort, the Abt workforce had a slight head begin: In line with info from Motorsport-Whole.com, the Lamborghini workforce had already tried the change two weeks earlier than the Zandvoort weekend throughout their single non-public check day per season, which Abt utilized at Zandvoort on Could 8.
The change primarily has a optimistic impact in high-speed corners, because it makes the automotive aerodynamically extra steady. Moreover, it helps the steadiness, because the Temerario GT3 beforehand generated far too little downforce on the rear axle, making the automotive unstable, particularly in quick corners.
For the reason that automotive now generates a couple of extra kilograms of downforce on the rear axle, the highest pace of the automobile decreases. To compensate for this, the Temerario acquired as much as 0.1 bar extra increase strain within the excessive RPM vary at Zandvoort, which suggests DTM and SRO are as soon as once more working outdoors the FIA’s homologation window.
“You must work with the automotive in a totally totally different means”
For the Grasser workforce, the change at Zandvoort meant a serious adjustment. “We had been looking a bit originally,” Grasser defined. “When it comes to philosophy, you now need to work with the automotive in a totally totally different means. And that wants driving expertise. The 2 apply classes are nearly not sufficient for that. Due to this fact, the primary a part of the weekend was like a check.”
Whether or not it felt like a brand new automotive? “Sure and no, that may be an exaggeration,” he replied. “However it’s a main impression the place you now need to be taught step-by-step.” Because of this they made a giant leap from Saturday to Sunday, which was additionally demonstrated by Mirko Bortolotti’s fourth place on the grid.
Whether or not Grasser believes the progress at Zandvoort was additionally associated to the abrasive asphalt and the excessive temperatures? “No, I imagine it can usually go higher,” he mentioned. “The excessive vitality from the monitor and the upper temperatures definitely helped us, however that additionally applies to different tracks when it is heat.”
