Chine : Mercedes et Ferrari changent tout, ou presque !

Le Grand Prix de Chine est l’occasion de faire un point sur les éléments mécaniques qui ont pu être changés depuis le début de saison. Ainsi, la FIA, par l’intermédiaire de plusieurs documents officiels, permet de suivre, tout au long d’un week-end de course, l’ensemble des opérations de remplacement effectuées sur les monoplaces.

Cette saison, une telle série d’informations a toute son importance, le Règlement sportif (article 28.4a) obligeant les équipes à respecter, pour chaque voiture, un quota maximum de cinq unités de puissance, ces dernières comprenant une série de 6 pièces qui peuvent elles-mêmes être remplacées, individuellement, dans la limite de cinq.
Ces pièces sont :
– le moteur thermique
– le turbocompresseur
– la batterie
– le MGU-K
– le MGU-H
– l’unité de contrôle électronique

Au-delà de ces quotas, des pénalités de 5 ou 10 places sur la grille peuvent être appliquées (<a href="/f1/actualite/16729-fia-les-evolutions-du-reglement-sportif-2014.html" target="_blank" title="FIA : les évolutions du règlement sportif 2014">voir cet article</a>).

Ainsi, avant la journée de samedi et les qualifications, voici l’ensemble des éléments qui ont été modifiés sur les monoplaces.

<b>Changements de boite de vitesses</b>
Concernant les boites de vitesses, elles doivent réaliser 6 Grands Prix consécutifs. Cependant, en cas d’abandon lors de la course précédente, les pilotes sont libres d’en changer sans écoper de la pénalité de 5 places sur la grille normalement infligée. C’est ici le cas des 5 pilotes qui ont effectué un remplacement ce week-end.
