May the DTM introduce draconian penalties sooner or later for groups that conceal their efficiency to achieve a extra favorable Stability of Efficiency (BoP)? Within the US-based IMSA sequence, that is already frequent follow – and based on info from Motorsport-Complete.com, groups and producers within the DTM at the moment are calling for comparable measures.
On the coronary heart of the talk is the Manthey group, winners of Saturday’s DTM opener in Spielberg. Thomas Preining was 1.280 seconds sooner in Saturday’s qualifying than he was the day prior to this throughout a qualifying simulation in a specifically scheduled BoP session. This didn’t sit effectively with the competitors.
“We confirmed what we’re able to within the follow periods and the qualifying simulation; we’re completely clear, we disclose the whole lot, and we push. And others do not try this,” says a annoyed Thomas Jäger, who serves because the Sporting Director for Mercedes-AMG’s DTM undertaking.
Mercedes-AMG sees a transparent case of “sandbagging”
“It’s kind of disappointing as a result of all of us have the objective of seeing this platform develop effectively. That may solely work if we’ve as little dialogue as potential surrounding this matter,” says the previous DTM driver.
“That is why I imagine everybody ought to play alongside once we do these BoP runs. Once you see how huge the distinction is between the BoP runs and the qualifying consequence, there isn’t any level in doing them.” To be able to enable for a good classification, one ought to “not attempt to cowl something up simply to achieve a bonus in a while,” says Jäger, who sees this as a transparent case of “sandbagging.”
Whereas he doesn’t point out Manthey immediately by identify, the suspicion is apparent, particularly as others within the paddock are being extra vocal. “How can it’s that Manthey is on the again throughout the BoP run, after which qualifies close to the entrance the following day?” wonders HRT Workforce Principal Ulrich Fritz.
“Manthey both has no clue, or they’re taking part in video games”
“And what occurred the following day, nobody understands anymore,” he provides, referring to Manthey’s lack of efficiency on Sunday following Thomas Preining’s Saturday victory. “Both they haven’t any clue what they’re doing, or they’re taking part in video games,” he says. “And Manthey is just not a group that has no clue.”
What’s his stance on draconian penalties for a BoP bluff? “I’m completely in favor of it,” Fritz replies. “I can not choose whether or not Manthey deserved a penalty as a result of I haven’t got the info, however this extra session value an excessive amount of cash, an excessive amount of consideration, and an excessive amount of time.”
However let us take a look at the details: The qualifying runs, which have been known as on quick discover for Friday as a 20-minute session with a brand new set of tires and subsequent technical scrutineering, have been dominated by Mercedes-AMG. Lucas Auer set the quickest time of 1:28.204 – simply 0.002 seconds forward of Jules Gounon and 0.006 seconds forward of Maro Engel.
Preining, one of the best driver within the new Evo model of the Porsche in eighth place (1:28.731), was 0.527 seconds off the tempo. This was putting, because the Manthey driver had already clocked a 1:28.351 throughout the official take a look at in Spielberg, practically four-tenths sooner. In Saturday’s qualifying, pole-setter Engel set a brand new lap file with a 1:27.403, whereas Preining took third with a 1:27.451 – 1.280 seconds sooner than his Friday BoP run.
ECE worth and monitor temperature? How Manthey explains the bounce
How does Manthey clarify the bounce? Patrick Arkenau, who acts as Racing Director at Manthey, factors to the monitor circumstances and the ECE correction issue. That is the usual process for normalizing dyno measurements to get rid of environmental influences reminiscent of air strain and temperature.
The ECE worth was “two % worse on Friday at the moment than throughout the take a look at and the precise qualifying,” Arkenau explains. “In the long run, that accounts for nearly precisely two % of engine energy.” With an output of 500 hp, that quantities to 10 hp. “A big a part of the distinction might be defined by that alone.”
However does not that additionally play a task for the Mercedes-AMG GT3? “We had a monitor temperature that was 13 levels larger on Friday than in qualifying,” Arkenau provides. “We all know our automotive is delicate to that – that is additionally a part of the reason. And we’re nonetheless studying with the brand new tire.”
Arkenau’s dig at AMG: “I’d sweep my very own doorstep first”
What does he take into consideration draconian penalties if somebody bluffs on the BoP? “I’d additionally welcome extra transparency, however there are two sides to the coin,” he says critically. “How can I even differentiate between regular improvement and sandbagging? Do I need to punish a driver who had a nasty day after which has day? I am unable to punish one thing I am unable to show.”
Arkenau could not resist a small dig at Mercedes-AMG: “If three vehicles from one producer are inside six-thousandths of a second in that run, you possibly can additionally say they could know precisely how briskly they should drive. Earlier than leaning out the window as a producer, I’d maybe sweep my very own doorstep first.”
Are the brand new sensors ineffective?
What can be irritating some groups: Earlier than the brand new season, new standardized sensors needed to be put in within the vehicles. These measure, amongst different issues, tire strain, tire temperature, experience top, and gas circulate to make BoP classification extra correct and to watch the groups extra successfully.
For older fashions just like the Mercedes-AMG GT3, this resulted in prices of round 100,000 euros per group. “It was utterly pointless for those who see that knowledge was taken throughout this BoP run – after which a participant who is sort of a second and a half sooner afterward is not penalized,” says one group member who wished to stay nameless.
