Ferrari 2022: will there be innovative solutions to the rear?

Project 674 has been 'working' for two years in Maranello
The 2022 cars will have an extremely different aerodynamic concept than the current ones. They will be machines rather unbalanced at the rear and therefore more limited at the front. In short, there is an 'intrinsic' understeer in the new concept of cars that will tend to have to change the driving style on the part of the drivers.
"Not everyone will adapt in the same way: there will be a lot to learn," said Mattina Binotto in the post Abu Dhabi. “The cars will look more like Formula 2 and therefore those who did well in that world championship will probably be fast on the new cars too” commented the team principal of the Italian team.
Also in terms of setup it will be something different than in recent years with more neutral set- ups than in 2021 and less 'concerned' about protecting the rear .
Aerodynamics: main focus on the rear
Ferrari 2022 was born under the banner of cautious but decisive optimism . Mainly for two factors. Having consciously sacrificed 2 years , hence the very little development work, towards 2020, of the SF90 precisely to focus on the new cars that should have initially debuted in 2021 (then Covid postponed the debut to 2022), and on the SF21. In addition to having solved in an important way the age-old problem of data correlation, which was a fundamental node for having tools available to transform the ideas of the technical office into something truly productive on the car. A problem that has been worked on a lot in the last 18 months, with important results.
A clear example of what must not be repeated are the funds delivered by the SF1000, the SF90 and (in part) also the SF71H. All macro components born from a sort of technical misunderstanding. In order to manage the flows in an optimal way, we resigned ourselves to penalizing the rear tires at times (overheating), at times the aerodynamic efficiency of the car , using wings with greater aerodynamic resistance. A problem solved on the rear of the SF21.
After the homologation of the frame, the 'last' aerodynamic resources have long been concentrated on the rear. We know that with the budget cap there is no possibility of infinite development on multiple areas, it is essential to decide the area of greatest opportunities. The suction cup bottom will have an inlet air flow greater than the current cars, this flow must be suitably slowed down, but above all it must be disposed of through the diffuser avoiding stalling when speed and load vary.
In this sense, we have heard that the regulation leaves some opportunities in that macro area of the new car , so much so that in Maranello they are testing an "innovative diffuser" in the gallery, a rather different solution from that seen on the Silverstone Fia dummy.
At Maranello they are convinced that it will be very important to have maximum rear stability and traction in order to increase the front load without needing a rear wing that generates an exaggerated drag to balance it in slow motion.
Power unit: Ferrari can no longer afford a power deficit
In Russia, the new ERS was introduced on the SF21 which was a success in terms of reliability and performance. Analyzing the gps data it was verified how significant the step was , enough to clear the gap from the super efficient McLaren.
After the hybrid update already seen on the track, all the effort is aimed at the internal combustion engine (ICE) . A source told us that the 2022 power unit showed “ power levels that are adequate to what we expect from the competition. The work is now proceeding on the reliability front. Once we are satisfied we will go back to implementing the hybrid part during the current season ".
We remind you that in terms of homologation, endothermic, turbocharger, MGU-H, exhaust, petrol and oil must be approved by 1 March 2022 . While the battery, the electronic control unit and the MGU-K motor generator by 1 September 2022. ..."
