Inkuru nziza mubisanzwe itangirana na "rimwe na rimwe hariho itsinda ryinshuti". Ibi ntibisanzwe. Ninkuru ya Gerard Welter na Michel Meunier, inshuti ebyiri, uwashushanyije na injeniyeri, kuri Peugeot, bahisemo gutanga ibisobanuro bishya kumvugo yishimisha.
Welter na Meunier bemeje ko umwanya wabo w'ubusa uzahabwa intego imwe… irarikira. Tegura urugendo muri Afrika? Kurira Everest? Menya impamvu idirishya ryimbere kuruhande rwibumoso bwa Renault Mégane rifite ubuzima bwonyine? Nta na kimwe muri ibyo. Kurusha abandi irari!
Izi nshuti zombi ziyemeje gushinga itsinda ryamarushanwa, guteza imbere imodoka kuva kera no gusiganwa mumasaha 24 ya Le Mans - ibibazo byimodoka yanjye bigomba gutegereza… Hari mumpera za 60 ubwo ikipe ya WM - izina rituruka guhuza inyuguti yambere yizina ryabo - amaherezo yafashe imiterere.
imyaka yambere
Mu 1976, WM yatonze umurongo bwa mbere mumasaha 24 ya Le Mans, murwego rwa GTP (Grand Touring Prototype) hamwe na moteri ikomoka kuri Peugeot (mubisanzwe…). Ikipe yari igizwe ahanini nabakorerabushake kandi kubitsinda rifite imiterere nkiyi yo kwikunda ibisubizo byari byiza cyane. Ariko, hamwe nitsinda rya C hamwe niterambere ryimyuga ya siporo, WM yatangiye gutakaza ubushobozi bwo guhatanira amarushanwa. Kandi nkuko tubizi neza, mumodoka ntamuntu ukunda gutakaza cyangwa ibishyimbo.
Hari igihe mubuzima iyo "byose cyangwa ntacyo" kandi WM yahisemo kubishyira mu kaga. Itsinda ryahaye abakanishi kongera umuvuduko wa turbos.
Nyuma yisohoka rya 1986 ryamasaha 24 ya Le Mans, yaranzwe nibisubizo bidashimishije, Welter na Meunier bahisemo ko wenda igihe cyo gutangira gutekereza ku kindi cyerekezo cya WM.
Hafi ya kure, izi nshuti zombi ziyemeje kwishyiriraho intego nshya kuri WM. Kuva uwo mwanya, imbaraga zose nubutunzi byashyirwa mubikorwa bimwe: guca inzitizi 400 km / h kuri Mulsanne igororotse kuri Le Mans. 'Umushinga 400' wavutse.
Ukurikije imodoka yo guhatana yari imaze guha WM umunezero mwinshi, iyi kipe idatinyuka yateje imbere WM P87 Peugeot . Icyitegererezo gishingiye kuri "kera" aluminium monocoque chassis hamwe nuburyo bwo hagati bwimiterere yumugongo - kugirango habeho gukomera kurwego - hamwe no guhagarika byigenga kumashoka yombi. Mubisanzwe, imbaho zose zo hanze zaravuguruwe. P87 yari yagutse kandi ndende kurenza "umwimerere" WM, hagamijwe kugabanya gukurura indege bityo bikongera umuvuduko mwinshi.
Iyandikishe mu kanyamakuru kacu
Peugeot yahisemo gushyigikira umushinga kandi mumezi arenga ane yahaye WM uburenganzira bwo gukoresha umuyaga. Gusa ku cyumweru, birumvikana. Inkunga ya Peugeot, mubyukuri, imwe mumpamvu zatumye ikipe igenda neza. Usibye umuyoboro wumuyaga, Peugeot yanatanze moteri ya PRV.
PRV yari isosiyete yavuye mubufatanye bwa Peugeot, Renault na Volvo, hagamijwe guteza imbere no gukora moteri nini zo kwimura. Iyi moteri ya PRV ifite ibikoresho bya WM P87 yakoresheje ubwubatsi bwa V6 ifite 2.8 l yubushobozi, ishoboye kurenga 850 hp yingufu , tubikesha ubufasha bwa turbos ebyiri.
kugerageza bwa mbere ... byarananiye
Mugihe imodoka ya Group C yakoresheje ibisubizo byindege kugirango yongere umuvuduko mwinshi, kuri WM P87 Peugeot impungenge zari zitandukanye: kwihuta cyane . Nubwo P87 itondagura ibaba ryinyuma ninyuma imbere, intego yiyi migereka ntabwo yari iyo kubyara ingufu, ahubwo ni uguhagarika imodoka.
Mu kizamini cya mbere kuri Le Mans, kubera ibibazo byubuyobozi bwa elegitoronike, umuvuduko ntarengwa wageze kuri "gusa" 356 km / h. Ariko mu kizamini cyakurikiyeho cyakorewe mumihanda (itari yugururiwe rubanda) ibisubizo byari bishimishije. P87 yiyandikishije 416 km / h yumuvuduko wo hejuru. Ibintu byose byari kumurongo kugirango bice amateka yihuta kuri Le Mans.
Ikipe yari ifite icyizere, ariko bidatinze kwibeshya byatanze inzira yo gutenguha. Amavuta ya octane make yateje ibibazo bikomeye kuri moteri (pre-detonation no gushyuha cyane) hanyuma nyuma yinshuro 13 gusa abakanishi baritanze. Haracyariho, harahari ibirometero bihagije kugirango P87 yandike umuvuduko wo hejuru wa 381 km / h.
WM ntabwo yageze kuri 400 km / h yari igamije, ariko byibuze byangije umuvuduko wo hejuru kuri Le Mans. Ikirahuri cyuzuye ...
Gerageza kabiri ...
Welter na Meunier ntibataye igitambaro hasi. Ubushobozi bwumushinga bwari buhari kandi muri 1988 bagarutse bafite imodoka ebyiri. WM P88 Peugeot (ubwihindurize bwimodoka yumwaka ushize) hamwe na WM P87 Peugeot yabanjirije hamwe na pake nshya yindege.
Ugereranije n'imodoka y'umwaka ushize, amakuru akomeye kuri WM P88 Peugeot yari moteri no guhagarika inyuma. Bitewe no kwiyongera gake kwimura moteri, ingufu zirenga 900 hp.
Mu isomo ryambere ryikizamini, P88 "yafashwe" na radar kuri 387 km / h. Ikirahuri cyatangiye kugaragara gake kandi gake "igice cyuzuye" gitangira kugaragara cyane "igice cyubusa". Nkaho ibyo bidahagije, P87 yavuye mumarushanwa, kubera ibibazo byo kwanduza, nyuma yiminota 13 gusa. Kandi ibintu bya WM P88 Peugeot ntibyari bigishimishije…
Roger Dorchy, umwe mu bashoferi ba WM, yashoboye gukurura P88 mu mwobo nubwo ibibazo bya moteri ndetse no gucunga umubiri. Mu masaha arenga atatu, abakanishi bagerageje gukemura ibibazo byimodoka. Barabikora. Byari ubu cyangwa nta na rimwe…
Byose cyangwa ntacyo!
Hari igihe mubuzima iyo "byose cyangwa ntacyo" kandi WM yahisemo kubishyira mu kaga. Itsinda ryategetse abakanishi kongera umuvuduko wa turbos, maze basaba Roger Dorschy gukurura moteri nyinshi zishoboka muri Mulsanne. Mu bihe byakurikiyeho, WM P88 Peugeot yambutse 400 km / h inshuro nyinshi.
Nubwo umuvuduko ntarengwa wageze kuri 407 km / h, bisabwe na Peugeot, itsinda ryiyemeje kuvugana n'agaciro… 405 km / h. Kuki? Kubera itangizwa rya Peugeot 405.
Mubisanzwe, hamwe nibibazo byose nari maze kugira no kwiyongera k'umuvuduko wa turbo, byari ikibazo mbere yuko P88 isubira mu byobo kandi ntizigera igaruka.
Ibibazo by'amashanyarazi, ibibazo byo gukonjesha nibibazo bya turbo, imodoka "yagumishijwe" ninsinga ariko irayobora!
Mu 1989 ikipe ya WM yagarutse muri Le Mans ariko ntiyitabira isiganwa. Nibwo bwa nyuma WM yinjiye mu masaha 24 ya Le Mans.
Nkuko mubizi, muri 1990 chicane ebyiri zongewe kuri Mulsanne igororotse. Impinduka igomba kwemeza ko mumateka yamasaha 24 ya Le Mans ntayindi modoka izigera irenga amateka ya 407 km / h ya WM P88 Peugeot. Tuzaba hano kureba…
