dangers of strategic F1 engine rotation and part utilization


Scuderia Ferrari and Charles Leclerc are dealing with a fragile problem. Within the turbo-hybrid period, the gradual tightening of the utmost restrict on homologated energy unit and transmission parts has turn out to be so restrictive that almost no staff has managed to remain inside these regulatory bounds with out incurring penalties throughout a Components 1 season. Regardless of the spectacular reliability requirements achieved by energy unit producers, the ultimate races of this F1 championship may nonetheless compel groups to take penalties as a result of extra use of parts past the allowed restrict.

Present championship chief and almost definitely championship winner Max Verstappen used his sixth inside combustion engine final weekend on the 4.309-kilometre Autodromo Jose Carlos Tempo in Brazil, which positioned him in the back of the beginning grid for Sunday’s Sao Paulo Grand Prix. Max Verstappen’s Sunday efficiency will go down in Components 1 historical past; nonetheless, apart from the climate circumstances that highlighted his expertise, the Interlagos circuit has traditionally offered overtaking alternatives. As we method spherical 22 of the 2024 Components 1 marketing campaign, which is ready to happen on the 6.2-kilometre Las Vegas Strip Circuit in Nevada, USA, considerations are additionally rising across the energy unit sturdiness for Charles Leclerc.

Thus far, the 2 Ferrari drivers haven’t obtained any penalties due to environment friendly energy unit and transmission rotation. Nonetheless, the fourth full energy unit was put in on automotive quantity 16 again on the Dutch Grand Prix, which implies seven race weekends in the past, and it has been used constantly for each the qualifying classes and the race since Zandvoort. The wet weekend in Brazil extended engine life, sparing the facility items from cooling points that may come up in dry circumstances.

The engines have additionally been pushed more durable by the drivers in comparison with a completely dry weekend. In earlier races, Ferrari’s technicians and engineers have taken each doable precaution to guard the integrity of energy unit 066/12. For instance, on the Circuit of the Americas in Texas, Charles Leclerc was repeatedly requested to carry out carry and coast within the closing phases of the race, the place he had a major lead over his Maranello teammate.

In distinction, in Mexico Metropolis, the Monegasque driver struggled to maintain up with Carlos Sainz on a monitor identified to be demanding for engines as a consequence of low air density. Among the many remaining circuits, Las Vegas stands out as one the place overtaking is possible. The upcoming race, set on an United States-style metropolis speedway within the playing capital, will closely rely on engine energy.

It’s no secret that Ferrari’s ambitions are excessive for the third Components 1 race on American soil. Final yr, regardless of the restrictions of an SF-23 automotive that struggled with tire administration, Charles Leclerc took pole and got here inside hanging distance of Max Verstappen, who finally claimed the victory. With the primary situations of energy unit part utilization exceeding FIA limits, grid penalties are important. Max Verstappen was moved again ten grid spots in Belgium and solely 5 in Brazil as a consequence of changing simply the V6 combustion unit.

For Charles Leclerc, this may be the primary homologation of a number of parts exceeding the utmost restrict. The Ferrari driver has reached the restrict on the next usable parts: inside combustion engine, traction management, motor generator unit-heat, motor generator unit-kinetic, power retailer, management electronics, gearbox case and cassette and gearbox driveline, gear, change parts and auxiliary parts. What does the sporting regulation impose when the utmost variety of homologations is exceeded?

A ten-place grid penalty for the primary time any further factor is used, i.e., the fifth inside combustion engine, traction management, motor generator unit-heat and motor generator unit-kinetic or the third management electronics or power retailer. For subsequent makes use of of the identical kind of part, a 5-place penalty is utilized.

The weird format of the Nevada circuit affords important overtaking alternatives, additionally permitting for the good thing about a “recent” unit with a bit extra energy in comparison with one with heavy mileage. Nonetheless, if the Monegasque driver had been to obtain a ten-place grid penalty — even with pole place on Saturday — he would begin from the eleventh spot. That is removed from superb, particularly at a race the place Ferrari hopes to maximise factors to problem McLaren on the prime of the 2024 Components 1 Constructors’ Championship.

In hindsight, the Brazilian Grand Prix would have been a more sensible choice, the place the SF-24 supplied Ferrari fewer possibilities of success. It’s unclear whether or not this alternative is as a result of mileage already used on all 4 energy items obtainable for Charles Leclerc’s automotive or if it’s a safety measure to keep away from any threat of an influence unit failure. It is usually price noting that within the batch of energy items used on automotive quantity 16, there may be the engine that skilled a noticeable energy drop in Canada, which can not have been utilized in any official session because the Montreal weekend.
