Unyaka bekungu-1998, futhi i-Porsche yayicosha ama-laurels e-Le Mans nge-911 GT1-98. Kungaba ukunqoba kwe-16 kwalolu hlobo lomjaho kulo mjaho oyingwazi, naphezu kokuthi i-911 GT1 ingenakho ukuqhudelana nezimbangi ezifana neMercedes CLK-LM ehamba phambili noma iToyota GT-One. Kwakuyishwa labo elivumele iPorsche ukuthi iwine, ngakho-ke kwakudingeka imoto entsha.
Ngokushabalala kwe-GT1, yisigaba se-LMP900 (Le Mans Prototypes) kuphela esihlangabezane nemibandela edingekayo ukuze sihlose ukunqoba okuphelele ngo-1999. Ngemuva kwesibonelo esisha se-Le Mans, ethola ikhodi yangaphakathi ethi 9R3, ngamagama afana noNorman Singer kanye no-Wiet. I-Huidekoper.
U-Norman Singer ufana nempumelelo ye-Porsche emqhudelwaneni. Unjiniyela wezimoto, umsebenzi wakhe emnyangweni wokuncintisana womkhiqizo uthatha amashumi amane eminyaka. Uyena ngemuva cishe kwabo bonke abawine iPorsche eLe Mans ekhulwini leminyaka eledlule.
UWiet Huidekoper ungumklami wezimoto zomjaho waseDashi onezimoto ezifana ne-Lola T92/10 noma i-Dallara-Chrysler LMP1 ku-resume yakhe. Lo mklami wabamba ukunaka kukaSinger ngo-1993 ethula ukuguqulwa komgwaqo wakhe we-Porsche 962 ngesicelo se-Dauer Racing.
I-Dauer 962, eyakhiwe ngendlela efanele emgwaqeni futhi isizakala ngezikhala kumthetho omusha we-GT, ngokwesicelo sikaSinger, iphinde yaguqulwa yaba yisekethe ngokubambisana no-Huidekoper, futhi iphuma inqoba e-Le Mans ngo-1994.
Ukusebenzisana phakathi komculi no-Huidekoper kwaqina eminyakeni elandelayo, bebamba iqhaza ekuthuthukisweni kwe-Porsche 911 GT1, eyayizoqala ngo-1996. Ngokuvela ngakunye kwe-911 GT1, izibopho zika-Huidekoper nazo zanda, zafinyelela umvuthwandaba ekuthuthukisweni kwe-911 GT1- 98 eyawina i-24 Hours of Le Mans, njengoba kushiwo, ngo-1998.
Bhalisela iphephandaba lethu
Ukuze kuthuthukiswe i-prototype entsha ye-Le Mans, olandela i-911 GT1, ukukhetha kuwela ku-Huidekoper. Okuwukuphela kwesithiyo esidingekayo kuyo kuzoba ukugcinwa kwe-3.2 l twin-turbo boxer six-cylinder ye-911 GT1, isidingo esingadala inkulumompikiswano yangaphakathi eshubile ngemva kokuphothulwa kwe-9R3 - i-open cockpit prototype yaqedwa ngoNovemba 1998. U-Huidekoper uyakhumbula :
Uma ibukeka ibulewe ngabe ayisekho, lapho ngibalula ukuthi injini yendabuko eyi-six cylinder Umshayisibhakela IPorsche kwakuyiphuzu elibuthakathaka kuwo wonke umklamo.
Lo mshayisibhakela oyi-six cylinder ubengasenazo izinto ezinhle. Imithethonqubo yayijezisa izinjini ezikhokhiswe ngokweqile. Ama-V8 ase-Atmospheric avela kwezinye izimbangi nawo abelula—cishe abe ngu-160 kg uma kuqhathaniswa no-230 kg we-Boxer—futhi ayengasetshenziswa njengezakhi zesakhiwo semoto.
Lo mncintiswano - iBMW, Toyota, Mercedes-Benz neNissan - nawo uthuthuke njengoba usungene unyaka wesibili wokuthuthukiswa kwemishini yawo. IPorsche ayikwazanga ukuqhamuka nemoto, ephepheni, isivele ilahlekelwe yizimbangi. Ezinsukwini ezimbalwa ngemva kwale ngxoxo uhlelo lwe-9R3 lwaluzokhanselwa - kubonakale sengathi ukuphela kuka-9R3, kodwa indaba yayingeke iphelele lapha...
injini eyimfihlo
Ngo-March 1999, u-Huidekoper wabizwa emuva e-Porsche. Wamangala lapho enikezwa i-3.5 l V10 ekuqaleni eyayakhelwe i-Formula 1 - kwakungenye 'imfihlo yonkulunkulu' iphrojekthi, eyayihloselwe ukuvala isikhala se-V12 eyayinezinkinga i-Porsche eyanikeza i-Footwork Arrows ngo-1991.
I-V12 yaba inhlekelele enkulu kangangokuthi i-Footwork yasula inkontileka yokuhlinzeka nge-Porsche ngaleso sikhathi, yabuyela kuma-Ford Cosworth DFR V8 ayesetshenziswa ngaphambilini. Umphumela? IPorsche isele neV10 entsha ezandleni zayo, engakaqedwa. I-Porsche eyi-Porsche, ivumele ithimba lonjiniyela nelokuklama ukuthi liqedele ukuthuthukiswa kwenjini entsha ye-V10, njengohlobo lokuzivocavoca okungokoqobo. Njengoba ingenayo indawo yokufaka injini, iPorsche ivele yakhohlwa yile V10 iminyaka eyisikhombisa ezayo.
U-Huidekoper ukuthandile akubona. I-V10 ibiyinjini ehlangene nelula, inamandla alinganiselwa phakathi kuka-700 no-800 hp, kanye ne-pneumatic actuation yama-valve. Isiqalo esihle kakhulu se-LMP entsha, evusa i-9R3. I-prototype ekhona yatholwa, yashintshwa ukuze yamukele injini entsha futhi yathuthukiswa ezicini ezimbalwa.
Injini nayo ingaphansi kwezinguquko ukuze ibhekane kangcono nezivivinyo zokukhuthazela. Umthamo wayo ukhushulwa ngokulungiselelwa okubili okungenzeka, 5.0 no-5.5 l. Imithethonqubo yayisho izivimbeli zokungena, ezinciphisa uphahla oluphezulu lokuzungezisa okungenzeka, ngakho uhlelo lwe-pneumatic actuation yamavalvu lwalahlwa. Kwakudingekile ukuqinisekisa ukuphila isikhathi eside nokuba lula ekuhlanganiseni nasekulungiseni.
Abazange babe naso isikhathi sokuhlanganyela e-Le Mans ngalowo nyaka, nomsebenzi wokulungisa i-V10 ku-9R3 owawuzophothulwa ngoMeyi 1999. Kodwa, lapho umfuziselo usuqediwe, okunye ukuketula umbuso waseshashalazini!
I-9R3 ikhanseliwe nakanjani
Uhlelo lukhanselwe futhi. Kodwa-ke, abaphathi be-Porsche bavumele ukuqedwa kwe-prototype ye-Le Mans, ngisho nokuhlolwa okufushane kwezinsuku ezimbili ethrekhi ye-Porsche e-Weissach, no-Bob Wollek no-Allan McNish esondweni, abahlangabezane nezimo ezimbi. Naphezu kokuhlolwa, kuze kube yilolu suku akekho owaziyo ukuthi ingakanani ikhono leqiniso le-9R3, futhi ngeke sazi.
Kodwa kungani i-9R3 yakhanselwa ngokuzumayo lapho ukuthuthukiswa kwayo kwase kusondele ekupheleni kwayo?
Isizathu esikhulu sibizwa ngePorsche Cayenne. U-Wendelin Wiedekin, oyi-CEO ye-Porsche, kanye no-Ferdinand Piech ongusomandla wakwa-Volkwagen kanye ne-Audi bavumelana ngokuthuthukiswa ngokuhlanganyela kwe-SUV entsha, okuzodala i-Cayenne ne-Touareg. Kodwa ukwenza kanjalo, kwakudingeka ukuguqula izinsiza kwezinye izinhlelo eziqhubekayo.
Ngokusho kweminye imithombo, isivumelwano siphinde savimbela i-Porsche ekubambeni iqhaza emikhakheni ephezulu ye-endurance Championship isikhathi esiyiminyaka eyi-10. Kuyathakazelisa kakhulu, njengoba unyaka wezi-2000 uphawula ukuqala kokubusa okuseduze kwe-Audi kwe-Le Mans kanye nemiqhudelwano yokukhuthazela. Indlela kaFerdinand Piech yokugwema ukuncintisana okungaba khona?
IPorsche izobuyela esigabeni esiphezulu sokukhuthazela kuphela ngo-2014 nge-919 Hybrid. Izowina amahora angu-24 eLe Mans ngo-2015, 2016 nango-2017. Uma i-9R3 inamandla okudlula i-Audi R8? Ngeke sazi, kodwa sonke singathanda ukubona i-duel kusekethe.
Ukuphela kuka-9R3 kwakungasho ukuphela kwe-V10
Akukona konke okubi. Impumelelo ye-meteoric ye-Cayenne enempikiswano yangenisa inkathi entsha yokukhula nokuchuma e-Porsche. Ivumele ukuxhaswa ngezimali kweCarrera GT ebabazekayo - eyethulwa ngo-2003 - eyayidinga kuphela ukulinda iminyaka eyi-11 ukuze kutholwe indawo yokwamukela ugesi eyi-V10.
Kulinganiselwa ukuthi okuwukuphela kwesibonelo esikhona se-9R3 sihlala siphelele futhi sitholakala kunoma iyiphi indawo yokugcina impahla ye-Porsche. Lokhu akusaphiki ukuba khona kwayo, nakuba zingekho izitatimende ezisemthethweni ngayo.
Ngokuzayo, i-Porsche ingase inqume ukuyiveza esidlangalaleni futhi yenze esinye isiqephu somlando wayo ocebile saziwe.
