Ferrari's main problem this year was certainly its engine... Ferrari's uneven performance in the last races of the 2022 Formula 1 season, which started in Mexico and extended to the "fight" they had against the team from Red Bull in Abu Dhabi, show how critical this problem was.
Anyone who has followed the team's trajectory this year knows that they had two problems to deal with: the first is the adjustment of the power unit, mainly the size of the turbo, which was not ideal for races at high altitude, such as the one that took place in Mexico. It's in Brazil.
The second was Mattia Binotto's confirmation after the last GP, as the team had to reduce engine performance in these last races because of reliability concerns.
In addition, Ferrari still had some failures of "great magnitude" and that cost a lot at the beginning of the campaign... Charles Leclerc incidents in Spain, then in Azerbaijan and finally the fire of Carlos Sainz in Austria . All this forced Ferrari to have to reduce the pace a little while they looked for a solution to the already existing problems.
I hope they now have enough time to get the shop in order and return for the 2023 season with everything set up.
These are good problems to have actually, because it means you bilt a good car but it has problems running, if you can make the reliability problem gone, and make the car running at 100% without issues, that means you are going to win many races. Of course that's not easy neither, but building a good car is even harder, fixing the DNF issues is a lot better than building a good car.
Ferrari also had a lot of troubles with pit strategy and tire strategy as well, we all saw this, they called pilots at the wrong times and often had wrong tire choices as well. If they can fix the reliability issue and also the strategy team, then they have a very good chance to win it next year.
