THE BMW i8 , ebone imveliso yayo iphelile kulo nyaka, yayiyimoto yokuqala ye-plug-in hybrid yezemidlalo ye-brand yaseJamani. Ukuba kukho into eninzi malunga ne-i8 enomdla kwaye iyaqhubeka inomdla - ukuyila kunye nokwakhiwa, ngaphezu kwayo yonke into - ngoko kwakukho ukugxekwa okuphindaphindiweyo. I-374 hp yamandla aphezulu adibeneyo ahlala eshiya into efunekayo.
Akunjalo ukuba i-i8 yayingakhawulezi. Kodwa ukuba bekuya kubonisa ihlabathi elitsha ngokubhekiselele ekufezekiseni ukusebenza - kulo mzekelo, umtshato phakathi kwe-hydrocarbons kunye ne-electron - bekusoloko kukho imfuneko ye-i8 kunye nokusebenza okungaphezulu kunye / okanye kugxininise okuya kuphakama kwinqanaba le-100% iimoto zemidlalo ezivuthayo ezifana nePorsche 911 okanye i-Audi R8.
Ayizange yenzeke loo nto, kodwa oko akuthethi ukuba akuzange kuxoxwe okanye kuzanywe ukuyiphuhlisa. Ekubeni ngokwenene siye safumana ukwazi i-BMW i8, kwaziwa ukuba uAlpina wayesebenza kwinguqulelo yakhe yezemidlalo yangaphandle. Kwaye ngokwenyani ngokwesithethe, uAlpina uya kunika i8 umtsi omkhulu ekusebenzeni ngaphezulu kwe-i8 ebesiyazi.
Ngapha koko, kutheni singazange sibe neAlpina i8?
Ekugqibeleni sineempendulo. U-Andreas Bovensiepen, umlawuli olawulayo we-Alpina, ngodliwano-ndlebe kunye ne-BMW Blog, uqinisekisa ukuba ewe, kuyinyaniso ukuba baphuhlise "i-i8" yabo, kodwa iprojekthi yayiza kushiywa xa bebalekela kwiingxaki ezininzi.
Bhalisa kwincwadana yethu
Iingxaki eziye zavela ekugqibeleni kwisigqibo sokutshintsha i-1.5 l turbocharged ezintathu-cylinder yemodeli yochungechunge, eyaba ne-231 hp, enkulu kwaye inamandla 2.0 l turbocharged ezine-cylinder esiyifumana namhlanje kwi-BMW M135i. Kodwa apha ukutsalwa malunga ne-350 hp endaweni ye-306 hp.
UBovensiepen ubanga ukuba ngenjini ene-cylinder ezine, I-Alpina i8 iza kuzisa i-462 hp yamandla aphezulu adibeneyo kunye ne-700 Nm ye-torque ephezulu edibeneyo. , ukutsiba okucacileyo kumandla, kokubini kwaye, sifuna ukukholelwa, ekusebenzeni.
Nangona kunjalo, nge-injini enkulu kunye namandla ngakumbi, iingxaki zokuqala zokupholisa zavela. Ukuzisombulula, uAlpina waqala ngokufakela i-intercooler enkulu, kodwa wagqiba ekubeni wongeze ezinye ii-intercoolers ezimbini, ezibekwe kwiifenda zangaphambili, ukugcina ioyile kunye nebhokisi yegiya kumaqondo obushushu afanelekileyo.
Kwimeko ye-gearbox, ibingasenamsebenzi wokupholisa isantya esisi-6 esizishintshayo sohlobo oluqhelekileyo. Oku akuzange kukwazi ukusingatha amandla ongezelelweyo enjini enkulu, ngoko bajika kwi-Aisin-speed-speed automatic transmission ehambelana nale njini namhlanje.
Ewe, kunye ne-injini kunye nokuhanjiswa okukhulu, kuye kwabonakala kuyimfuneko ukwenza i-aluminium yangasemva ye-sub-frame ukubaxhasa, eya kufuneka yomelele kunaleyo ikhoyo - utshintsho oluyimfuneko lugcinwe lufumba.
Ngaphambili, ukuze kupheliswe i-understeer ebonakalisa isimo sengqondo se-i8, i-Alpina ifake amathayi angama-50 mm ububanzi kune-195 emxinwa ukuba imodeli yochungechunge ixhotyiswe. Ngenxa yoko, kuye kwafuneka ukuba kuphuhliswe iifender ezintsha, ezinkulu ukuze kuhlaliswe irabha ebanzi.
Ngayo yonke le nto, i-injini enkulu kunye ne-gearbox enkulu, ii-intercoolers ezinkulu nezingaphezulu, iphinde yenza ubungakanani obungasemva bekhareji engaphantsi, i-Alpina i8 nayo iya kuba nzima malunga ne-100 kg. Akukho nto yakuzikhathaza ngayo malunga nesakhelo se-carbon fiber ye-i8, ebiqinile ngokwaneleyo ukujongana namandla anyukileyo kunye nobunzima, kungafuneki zixhaso. Kodwa i-100 kg eyongezelelweyo ithethe ukuba le Alpina i8 kufuneka iphinde iqinisekiswe ngokwemiqathango yokhuseleko, ngamanye amazwi, kuya kufuneka iphinde iimvavanyo ezixabisa kakhulu zokuphahlazeka ukuze ibe ne-homolog.
Kodwa ngokuka-Andreas Bovensiepen, olu tshintsho kunye neendleko ezihambelanayo zazingesona sizathu siphambili sokulahla uphuhliso lwe-i8 yakhe.
Isizathu sokuba "ibulale" iprojekthi ngokulungileyo
Esona sizathu siphambili sokuba bayishiye le projekthi yayikukulungelelaniswa kwekhonkco elintsonkothileyo le-kinematic. I-BMW i8 ineeyunithi ezimbini zamandla ezahlulwe ngokwasemzimbeni - i-injini yokutsha iqhuba i-asi yangasemva kunye ne-motor yombane iqhuba i-asi yangaphambili, ngaphandle kwento ebadibanisayo kunye - kodwa basebenzisana ngokuhambelanayo, ngokungathi banye. Kwaye oku kunokwenzeka kuphela kumbulelo kwisoftware elawula ukusebenza kweeyunithi ezimbini zokuqhuba, ezilungiselelwe ngokukodwa "byte" yazo.
Ngamanye amazwi, xa betshintsha i-injini yokutsha kunye nothumelo olufanelekileyo, baphulukene nolawulo olulungisiweyo kunye nokulinganisa. Kuya kufuneka bayenze kwakhona ngokupheleleyo. Kwaye ukwenza loo nto abayi kuchitha ixesha elininzi nje, njengoko ... kunzima kakhulu, kodwa kuya kuba kubiza kakhulu ukwenza oko.
Kwakungelo xesha apho u-Andreas Bovensiepen kunye neqela lakhe baphosa itawuli phantsi, njengoko bagqiba ukuba kwakungafanelekanga umzamo woluntu kunye nemali ukuqhubeka neprojekthi ukuze kuhlangatyezwane nemigangatho eqhelekileyo efunwayo e-Alpina. Iprototype yale Alpina i8 yenziwa yade yasebenza, kodwa ekugqibeleni yasilela ekudibaneni kokusebenza kweeyunithi ezimbini zamandla.
Mhlawumbi ubunzima kunye neendleko ezongezelelweyo zikwanceda ukuthethelela ukuba kutheni kungazange kubekho i8 evela kwi-BMW M, kwaye kungekhona nje ukusuka eAlpina.
