Last season was podium, the last high of Sebastian Vettel behind the wheel of a F1 all red. The adverse weather conditions gave a car a chance, the one with the Cavallino Rampant on the body, bizarre and at times undriveable, to shake off mediocrity. And so it was that the SF1000 it almost looked like a competitive single-seater. Expert, the German was quick to take advantage of the excessive optimism of Charles and at the last corner, of the last lap, the long of the Monegasque opened the door in the third place. Although the 2021 scenario undoubtedly sees a context where the SF21 will be able to express himself in a decidedly more competitive way, there will be several factors to be evaluated in order to extrapolate the most from the available package.
F1-Gp Turkey 2021-Ferrari analysis: aerodynamic and mechanical balance
The track that rises in the Asian part of the city of Istanbul offers several points where you can express the power of power unit. Nevertheless, the important presence of various guided areas forces the teams to adopt an aerodynamic package from high load. The mixed section features sequences of medium-fast curves that culminate in the famous curve 8, a left-hand bend composed of four apexes that the pilots now travel in full, thanks to the enormous downforce than the current ones F1 they are able to generate.
A fundamental aspect to put under the magnifying glass it’s about the different changes of direction it offers Istanbul Park, where an agile car will be able to make the most of its characteristics to obtain adequate chronometric feedback. In Russia we noticed how increasing the vertical load at the rear by a few points has considerably improved the behavior of the single-seaters. On the track that unwinds along the region of the Tuzlawe will probably see something different. A front axle a more loaded hair will determine a greater precision in insertion, essential to be able to extract the maximum from the mixed section.
From this point of view, the SF21 will be put to the test. We have often talked about the fact that many problems encountered on the car of the Cavallino are in some way attributed to a front not too performing and often uncertain. As proof of what has been said, the experience gained in the first two thirds of the 2021 calendar, where the Modena car on various tracks it was limited by the front axle which suffered from lack of rotation. Problem that has produced a stress excessive on the compounds.
The technicians of Maranello, therefore, they must be able to study the behavior of the car and suggest, once the feedback of the riders, the changes to obtain an optimal set-up and “contain” the aforementioned counterproductive behavior that on certain occasions comes to life on the front.
Adopt a setup front too soft to guarantee a grip higher, in this case, could also be in percentage against producing. This is because it would go to compromise the handling of the car when changing direction. We could therefore see a minimizing front end that is more loaded but which will still have to be balanced with the rear in order not to disadvantage the high-speed stretches of the track. A nice headache, in short.
F1-Gp Turkey 2021-Ferrari analysis: tires
From this point of view, too, the prospects are challenging for the Ferrari. Similarly to that observed in Russia, as mentioned earlier also Istanbul has a wide radius curve and high travel speed: the iconic number 8. Lo stress produced on the outside of the tire carcass will be really high on the push lap and above all it will negatively affect race pace on Sunday.
In detail, there are several points where i compound they will be forced to absorb an excess of energy, a situation that in all likelihood can cause the annoying phenomenon of overheating caused by lateral and longitudinal forces. This is why being able to keep the compounds stable and in the correct operating window will not be so obvious thinking about the intrinsic characteristics of the Rossa, a car that has often shown a fatal discrepancy between the axles. Factor capable of producing important aerodynamic imbalances that forced the Ferrari drivers to struggle a lot with the cars.
In Russia the compounds have given several headaches to the standard bearers of the Rossa and the technicians of Maranello, after having analyzed the data collected during the course on the simulator week, they did not have comprehensive answers on the behavior of the car at that time Sochi. Side note, it should be noted that the micro roughness of the asphalt of the Turkish track will certainly be better than that present during the past season. The various interventions carried out in recent weeks, in fact, with the clear objective of raising the grip in wet track conditions they will be noticed even on dry surfaces.
F1-Ferrari Gp Turkey preview: propulsion
Considering the type of track, the downforce that will be used and the length of the course, 10 hp at Istanbul Park is worth about 2 tenths of a second for each lap. At first glance we could define the Turkish track as not too sensitive to the power of the engines. Nonetheless, the single-seaters travel about 70% of the lap with the throttle open. The endothermic, consequently, will play an important role that will necessarily have to be supported by the hybrid part of the Italian power unit.
Taking into consideration the layout from Istanbul we can say that the only real challenging braking is that relating to turn 12. Although the lack of strong braking will make the task of the‘MGU-K decidedly less incisive, the recovery of the kinetic energy and enthalpy of the excess exhaust gases, obtained through the motion generator MGU-Hhowever, it will play a key role.
Element that it was revised in the last update produced by the engineers of Maranello during the last month which, despite the increase limited to a percentage on each round as it is governed by technical-sporting regulations, is able to increase the competitiveness of the system hybrid supported by much more efficient batteries able to maximize the phases of accumulation, management and release of electric power.
As anticipated by FUnoAnalisiTecnica yesterday morning (read the full report here), both SF21 will be equipped with the latest specification of power unit produced by the Modenese stable and the same Carlos Sainz can take advantage of the extra power made available by the update. Surplus available from the hybrid system which will undergo a further small increase during this weekend, approved following good results on reliability.
