China: Mercedes and Ferrari change everything, or almost!

The Chinese Grand Prix is an opportunity to review the mechanical components that may have been changed since the start of the season. Thus, the FIA, through several official documents, enables tracking, throughout a race weekend, of all replacement operations carried out on the cars.

This season, such a series of information is of utmost importance, as the Sporting Regulations (article 28.4a) require teams to adhere to a maximum quota of five power units per car. These include a set of six components that can themselves be replaced individually, within the limit of five.

These parts are:

– le moteur thermique

– le turbocompresseur

– la batterie

– le MGU-K

– le MGU-H

– l’unité de contrôle électronique

Beyond these quotas, penalties of 5 or 10 places on the grid may be applied.

Thus, before Saturday’s session and the qualifications, here are all the elements that have been modified on the cars.

Changes made to the power unit components

Gearbox changes

Regarding gearboxes, they must complete 6 consecutive Grand Prix races. However, if there is a retirement in the previous race, drivers are free to change them without incurring the usual 5-place grid penalty. This is the case for the 5 drivers who made a replacement this weekend.
