Le g\u00e9ant britannique de la machinerie agricole et de construction JCB<\/a> a \u00e9tabli un nouveau record<\/a> du monde de vitesse terrestre de la F\u00e9d\u00e9ration internationale de l’automobile (FIA) hier lorsque l\u2019Hydromax, son bolide aliment\u00e9 \u00e0 l’hydrog\u00e8ne, a atteint la vitesse de 653,91\u00a0km\/h (406,320 mi\/h) sur le lac sal\u00e9 de Bonneville<\/a>, en Utah.<\/p>\n

Andy Green, 64\u00a0ans, un pilote de chasse de la Royal Air Force, \u00e9tait aux commandes de l\u2019Hydromax. Il a effectu\u00e9 en moins d’une heure les deux essais (aller-retour) requis par le r\u00e8glement de la FIA.<\/p>\n

Le 6 ao\u00fbt, Green et son v\u00e9hicule avaient annonc\u00e9 leurs couleurs en atteignant 592,8\u00a0km\/h au m\u00eame endroit, un record d\u00e9croch\u00e9 dans le cadre de la Semaine de la vitesse de Bonneville, un important \u00e9v\u00e9nement d\u2019\u00e9preuves chronom\u00e9tr\u00e9es organis\u00e9 par la Southern California Timing Association (SCTA).<\/p>\n

Un aller-retour \u00e0 la vitesse de l\u2019\u00e9clair<\/strong><\/h3>\n

\nPour le record de la FIA, Green a enregistr\u00e9 une vitesse moyenne de 644,74\u00a0km\/h (400,623 mi\/h) lors du premier essai et 663,27\u00a0km\/h (412,135 mi\/h) lors du second. Cela donne la moyenne de 653,91\u00a0km\/h qualifi\u00e9e de vitesse la plus \u00e9lev\u00e9e jamais atteinte par un v\u00e9hicule \u00e0 combustion interne \u00e0 hydrog\u00e8ne.<\/p>\n

Le nouveau record de JCB doit maintenant \u00eatre homologu\u00e9 par la FIA, l’instance dirigeante mondiale du sport automobile, dans la cat\u00e9gorie\u00a0A (groupe\u00a0XIV, classe\u00a06), une cat\u00e9gorie de records du monde de vitesse terrestre avec d\u00e9part assist\u00e9.<\/p>\n

En effet, pour cette cat\u00e9gorie, le r\u00e8glement de la FIA autorise les v\u00e9hicules \u00e0 recevoir une pouss\u00e9e sur une distance maximale de 300\u00a0m au d\u00e9part de chaque essai. C\u2019est d\u2019ailleurs un Defender\u00a0Octa biturbo fourni gracieusement par Land\u00a0Rover qui a rempli cette t\u00e2che d\u2019assistance.<\/p>\n

1\u00a0600\u00a0ch sous le capot<\/strong><\/h3>\n

\nLong de 9,8\u00a0m, le bolide aux formes effil\u00e9es est anim\u00e9 par deux moteurs \u00e0 combustion interne JCB de s\u00e9rie aliment\u00e9s \u00e0 l\u2019hydrog\u00e8ne. Ils d\u00e9veloppent une puissance combin\u00e9e de 1\u00a0600\u00a0ch.<\/p>\n

Andy est un habitu\u00e9 du monde des records. En 1997, il \u00e9tait devenu l’homme le plus rapide du monde apr\u00e8s avoir atteint la vitesse stup\u00e9fiante de 1\u00a0227,99\u00a0km\/h aux commandes du Thrust\u00a0SSC. Du coup, il devenait aussi le premier humain (et le seul \u00e0 ce jour) \u00e0 avoir franchi le mur du son sur terre.<\/p>\n

Cette fois, avec l\u2019Hydromax, Green a battu \u2014 et de loin \u2014 le pr\u00e9c\u00e9dent record de vitesse homologu\u00e9 par la FIA pour un v\u00e9hicule \u00e0 combustion interne \u00e0 hydrog\u00e8ne, soit 298,7 km\/h, la vitesse atteinte par la BMW\u00a0H2R en septembre 2004.<\/p>\n

Deux autres records d\u00e9pass\u00e9s<\/strong><\/h3>\n

\nEn attendant la sanction officielle de la FIA, JCB se r\u00e9jouit \u00e0 l\u2019id\u00e9e que son nouveau record en surpasse deux autres qui s\u2019y apparentent et qui ont \u00e9t\u00e9 r\u00e9alis\u00e9s au m\u00eame endroit.<\/p>\n

Le premier est le record de vitesse pour un v\u00e9hicule \u00e0 moteur diesel de 563,42\u00a0km\/h \u00e9tabli par le m\u00eame Andy Green aux commandes du JCB Dieselmax. C\u2019\u00e9tait en ao\u00fbt 2006 et, chez JCB, on se targue de \u00ab\u00a0n\u2019avoir eu besoin que de 20\u00a0ans\u00a0\u00bb pour \u00e9tablir un nouveau record avec un moteur ne produisant aucun rejet de CO2 dans l\u2019atmosph\u00e8re.<\/p>\n

Et puisqu\u2019il est question d\u2019hydrog\u00e8ne, l\u2019Hydromax a \u00e9galement surpass\u00e9 le record de vitesse pour un v\u00e9hicule \u00e0 piles \u00e0 combustible \u00e0 hydrog\u00e8ne de 487,63\u00a0km\/h \u00e9tabli en 2009 par le Venturi Buckeye\u00a0Bullet\u00a02 (ou VBB2), un bolide construit par une douzaine d\u2019\u00e9tudiants du d\u00e9partement d\u2019ing\u00e9nierie de l\u2019Universit\u00e9 de l\u2019\u00c9tat d\u2019Ohio sous la supervision de Venturi, de Monaco.<\/p>\n
