Iro gore raive 1998, uye Porsche yaive ichinhonga nhanho paLe Mans ne911 GT1-98. Kungave kuhwina kwechigumi nematanhatu mujaho une mukurumbira, kunyangwe iyo 911 GT1 kushaya kukwikwidza kune vakwikwidzi vakaita seakanyanya Mercedes CLK-LM kana Toyota GT-One. Yakanga iri nhamo yavo yakabvumira Porsche kukunda, saka motokari itsva yaidiwa.
Nekutsakatika kweGT1, chikamu cheLMP900 (Le Mans Prototypes) chete ndicho chakasangana nemamiriro aidiwa nechinangwa chekukunda zvachose muna 1999. Seri kweiyo prototype itsva yeLe Mans, iyo inogamuchira kodhi yemukati 9R3, mazita akaita saNorman Singer naWiet. Huidekoper.
Norman Singer inofanana nekubudirira kwePorsche mumakwikwi. Injiniya yemotokari, basa rake mudhipatimendi remakwikwi emhando rinotora makumi mana emakore. Iye ndiye ari kumashure angangoita ese anohwina Porsche kuLe Mans muzana ramakore rapfuura.
Wiet Huidekoper mugadziri wemota yemujaho wechiDutch ane mota dzakaita seLola T92/10 kana iyo Dallara-Chrysler LMP1 pane yake kutangazve. Mugadziri uyu akatora pfungwa dzeSinger pakuvhurwa kwa1993 kwekushandurwa kwemugwagwa wePorsche 962 achikumbirwa naDauer Racing.
Iyo Dauer 962, yakanyatso kurongerwa mugwagwa uye kutora mukana wezvimedu mune nyowani GT regulation, iri, pakukumbira kwaSinger, yakadzoserwa kudunhu nekubatana kweHuidekoper, uye inobuda yakakunda kuLe Mans muna 1994.
Kubatana pakati peSinger naHuidekoper kwakawedzera mumakore akatevera, kutora chikamu mukuvandudzwa kwePorsche 911 GT1, iyo yaizotanga muna 1996. Nekushanduka kwega kwega kwe911 GT1, mabasa aHuidekoper akawedzerawo, zvichiguma nekuvandudzwa kwe911 GT1- 98 iyo yakahwina Maawa makumi maviri nemana eLe Mans, sezvataurwa, muna 1998.
Nyorera kune tsamba yedu
Nekuvandudzwa kweiyo prototype nyowani yeLe Mans, mutsivi we911 GT1, sarudzo inowira paHuidekoper. Chisungo chega chinodiwa pairi chingave kuchengetedza 3.2 l twin-turbo boxer six-cylinder ye911 GT1, chinodiwa chaizounza gakava remukati rinopisa mushure mekupedzwa kwe9R3 - iyo yakavhurika cockpit prototype inopedzwa muna Mbudzi 1998. Huidekoper anorangarira :
Kana chitarisiko chakaurayiwa chingadai chisisipo pano, pandakataura kuti chinyakare injini yechitanhatu-cylinder Boxer Porsche ndiyo yaive nzvimbo isina kusimba mudhizaini yese.
Iyo six-cylinder boxer yakanga isisina mabhenefiti. Regulations penalized overcharged engines more. Atmospheric V8s kubva kune vamwe vakwikwidzi zvakare aive akareruka — angangoita 160 kg achipikisana neBoxer's 230 kg — uye aigona kushandiswa sezvimiro zvemota.
Makwikwi aya — BMW, Toyota, Mercedes-Benz neNissan — akasimukirawo apo apinda mugore rechipiri rekugadzirwa kwemichina yavo. Porsche yaisakwanisa kuuya nemotokari iyo, papepa, yakanga yatorasikirwa nevakwikwidzi. Mazuva mashoma mushure mehurukuro iyi chirongwa che9R3 chaizomiswa - zvakaita sekunge kupera kwe9R3, asi nyaya yaisazopera pano…
injini yakavanzika
Muna Kurume 1999, Huidekoper akadanwa zvakare kuPorsche. Kukushamisika kwake, anounzwa ne3.5 l V10 yakatanga kugadzirirwa Formula 1 - chaive chimwe 'chakavanzika chevamwari' chirongwa, chaiitirwa kutsiva V12 yainetsekana iyo Porsche yakapa Footwork Arrows muna 1991.
V12 yaive njodzi yakakura zvekuti Footwork yakadzima kondirakiti yekugovera nePorsche panguva iyoyo, ichidzokera kune yaimboshandiswa Ford Cosworth DFR V8s. Mhedzisiro? Porsche yasara neV10 nyowani mumaoko, isina kupera. Porsche iri Porsche, yakabvumira iyo mainjiniya nedhizaini timu kuti ipedze kuvandudzwa kweinjini itsva yeV10, semhando yekurovedza muviri. Kushaya pekushandisa injini, Porsche yakangokanganwa nezve V10 iyi kwemakore manomwe anotevera.
Huidekoper akafarira zvaakaona. Iyo V10 yaive compact uye yakareruka injini, ine simba rinofungidzirwa pakati pe700 ne800 hp, uye pneumatic actuation yemavharuvhu. Nzvimbo yakanaka yekutanga yeLMP nyowani, inomutsa iyo 9R3. Iyo iripo prototype yakadzoserwa, yakashandurwa kuti igamuchire injini nyowani uye yakashanduka mune akati wandei.
Iyo injini zvakare iri pasi pekuchinja kuti itarise zviri nani kuomarara kwekutsungirira bvunzo. Kugona kwayo kunowedzerwa kune maviri anogoneka magadzirirwo, 5.0 uye 5.5 l. Iyo mirau yaireva inlet restrictors, kuderedza iyo inokwanisika kutenderera sirin'i, saka iyo pneumatic actuation system yemavharuvhu yakaraswa. Zvakanga zvakakodzera kuvimbisa hupenyu hurefu uye nyore mukuungana uye kugadzirisa.
Vakanga vasina nguva yekutora chikamu muLe Mans gore iroro, nebasa rekugadzirisa V10 kuenda ku9R3 raizopedzwa muna May 1999. Asi, apo muenzaniso wacho wakangopera, kumwe kupandukira kwemitambo!
9R3 yakabviswa zvachose
Chirongwa chakamiswa zvakare. Nekudaro, manejimendi ePorsche akabvumira kupedzwa kweiyo Le Mans prototype, uye kunyangwe bvunzo pfupi yemazuva maviri paPorsche track muWeissach, naBob Wollek naAllan McNish pavhiri, vakamhanyira mumamiriro ezvinhu asina kunaka. Pasinei nekuedzwa, kusvikira nhasi, hapana anoziva kuti chii chaicho chinogona kuitika che9R3, uye isu hatizombozivi.
Asi nei 9R3 yakangoerekana yakadzimwa apo budiriro yayo yaive pedyo kusvika kumagumo?
Chikonzero chikuru chinonzi Porsche Cayenne. Wendelin Wiedekin, CEO wePorsche, uye wemasimbaose Ferdinand Piech weVolkwagen neAudi vakabvumirana pakuvandudzwa kwekubatana kweSUV itsva, zvichipa Cayenne neTouareg. Asi kuita kudaro, zvaive zvakafanira kutsausa zviwanikwa kubva kune mamwe mapurogiramu aienderera mberi.
Sekureva kwemamwe masosi, chibvumirano chakadzivirirawo Porsche kutora chikamu mumapoka epamusoro emakwikwi ekutsungirira kwenguva yemakore gumi. Zvinonakidza kwazvo, sezvo gore ra2000 rinoratidza kutanga kwekutonga kweAudi pedyo-kwakazara kweLe Mans uye makwikwi ekutsungirira. Nzira yekuti Ferdinand Piech adzivise kukwikwidza?
Porsche yaizodzokera kuchikamu chepamusoro chekutsungirira chete muna 2014 ne919 Hybrid. Yaizokunda maawa makumi maviri nemana eLe Mans muna 2015, 2016 uye 2017. Kana 9R3 yaiva nekwanisi yekupfuura Audi R8? Hatife takaziva, asi isu tese taida kunge takaona duel padunhu.
Kupera kwe9R3 kwaisareva kupera kweV10
Hazvisi zvese zvakaipa. Kubudirira kwemeteoric kweCayenne yakapokana kwakaunza nguva nyowani yekukura nebudiriro paPorsche. Yakabvumira mari yeCarrera GT inoshamisa - yakatangwa muna 2003 - ichingoda kumirira makore gumi nerimwe chete kuti iwane chigadziko chakanaka chemagetsi V10.
Inofungidzirwa kuti iyo chete iripo prototype ye9R3 inoramba yakazara uye iri mune chero Porsche warehouse. Izvi hazvicharambi kuvepo kwayo, kunyangwe pasina zvirevo zvepamutemo nezvazvo.
Mune ramangwana, Porsche inogona kusarudza kuzvizivisa pachena uye kuita chimwe chikamu chenhoroondo yayo yakapfuma chizivikanwe.
