Development: all updates after Jeddah – Formula 1

Together with the understanding of the cars and the set-up choices, the development race is a central aspect in Formula 1, potentially capable of breaking the balance of a championship that in the first races saw Ferrari and Red Bull on the same level and a center- particularly compact group behind Mercedes. The single updates on the single-seaters guarantee marginal gains, but which, when added together over months or even within the same evolutionary package, make it possible to find important tenths, which in motorsport often prove decisive. In 2022 the teams are required to publicly declare the changes made to the cars from Grand Prix to Grand Prix, allowing for easier tracking. The following has been chosen to report the evolution of the single-seaters starting from the second test session and from the first Grand Prix in Bahrain. The use of specific wings for low or high load tracks is only carried over to the debut race of the component. Except for extreme solutions, the traditional operations of adjusting the cooling openings on the engine hood are omitted.

It is clear from the first two races of 2022 a widespread tendency of the teams to concentrate on the development of the car bottom, a determining component of around 80-90% of the competitiveness of current single-seaters, according to what Mattia Binotto estimates. The fairing of the rims and the sealing of the brake baskets exacerbated the cooling difficulties of the braking system, forcing Red Bull, McLaren and Alfa Romeo to revise their front air intakes. As for the packages for adaptation to low-load tracks such as Jeddah, Red Bull is the team that most modifies its car. In addition to the rear wing, a resized beam-wing is in fact provided, thus also reducing the extraction from the diffuser and consequently the load and resistance generated by the underbody. Regarding the fight at the top, Red Bull has introduced a relatively extensive evolution package on the occasion of the second tests in Bahrain. Ferrari on the other hand, after having progressively refined and evolved the fund in pre-season tests, preferred to invest more time to plan its own developments, postponing updates to the next races.

MERCEDES
