McLaren Method 1 group principal Andrea Stella says that the group will examine why it’s dropping round “one-and-a-half tenths” to Mercedes within the straights, regardless of working with a standard energy unit.
Explaining the place the MCL40 is presently stacked in opposition to the present championship-leading W17, Stella estimates that the hole between the 2 vehicles is round three-to-four tenths per lap, with “70% within the corners and 30% within the straights”.
Whereas the deficit within the corners is considerably simpler to clarify, because the McLaren is presently missing downforce versus the Mercedes, it is much less clear to the group the place the shortfall in straightline efficiency presently lies.
The straightforward assumption can be that the McLaren can be extra draggy and thus unable to succeed in the identical degree of acceleration, however the group additionally feels that it may very well be a discrepancy in how the 2 groups function the Mercedes powertrain.
This was some extent talked about earlier within the 12 months by Stella as Mercedes had a direct benefit in optimising its personal powertrain, though he was eager to stipulate that he was pleased with the dialogue between McLaren and Mercedes’ Excessive Efficiency Powertrains (HPP) division.
“With regards to our hole to Mercedes, it is at all times been between three and 4 tenths, it comes within the corners predominantly, in all probability 70% within the corners and 30% within the straights,” Stella defined in Austria.
“Within the corners, it is very clear why that’s the case, it is the truth that their automobile generates extra downforce than our automobile, and that is one thing that we’re engaged on, and we have now good tasks that can land trackside.
“The 30% occurring within the straights, it may need to do with some further aerodynamic drag that we have now on our automobile, however we’re additionally wanting on the manner we exploit the ability unit, as a result of the velocity deficit is kind of important.
“I do not know if in case you have entry to the GPS overlays, however I believe these days that is a extremely fascinating supply of knowledge to see the traits of the assorted vehicles. It is possible for you to to see that, as an illustration, there’s in all probability one-and-a-half tenths, one tenth no less than, that we lose within the straights, and undoubtedly we have to go and look into why that’s the case.”

Stella added that “reverse-engineering” the issue was tough, notably when trying to delineate between the 2 potential causes of the automobile’s decreased efficacy on the straights.
Whereas HPP is helping McLaren with serving to the group unlock additional beneficial properties by way of vitality deployment, Stella provided a easy rationalization to assist it perceive the difficulty: minimize the MCL40’s drag, and see if there’s nonetheless a deficit.
“The end result is that there’s a few kph distinction, however there may very well be a number of sources and it is a typical downside while you reverse engineer opponents; you possibly can’t successfully distinguish what is the drag from what is the from what is the energy unit,” he stated.
“I believe once we had been speaking about exploitation firstly of the season it was extra in relation to the sensitivities to deployment. You already know, deployment may be very delicate to driving model, very delicate to the way you distribute the deployment over the lap.
“From this standpoint, there’s been good progress, and good collaboration with HPP. We now have higher instruments because of the truth that HPP has helped the event of our instruments and we have now a more practical collaboration.
“I believe we’re higher by way of exploiting the ability unit from {an electrical} vitality deployment. However there’s additionally the ICE energy that we should always think about, and like I stated I can not discuss variations from an influence unit standpoint, as a result of simply assuming that the ability unit is similar – there could also be variations from a drag standpoint.
“I believe it is honest to concede that Mercedes can have much less drag than us, we have now completely different ratios, this may occasionally have an impact. There could also be another sources, the one factor I do know and the one factor that’s below our management is that we have to minimise all of the sources of drag on the MCL40 – and that is what we’re concentrating on, whereas we preserve a really tight collaboration with HPP.”
