Okujabulisayo umbono we-Porsche wezindondo zayo zohlobo olulodwa esikhathini sikagesi ngokwembulwa kwe- UMthunywa R , okusinika isithombe esibi sokuthi yini ongayilindela esizukulwaneni esizayo semishini yokuncintisana esebenza ngogesi.
I-Mission R iletha acishe abe ngu-1100 hp (amandla amakhulu angu-800 kW, noma angu-1088 hp) kumodi “Yokufaneleka” kanye nama-500 kW noma ama-680 hp aqhubekayo kumodi “Yomjaho,” inesisindo esingaba ngu-1500 kg, ifinyelela ngaphansi kuka-2 .5s phezulu ifinyelele ku-100 km/h futhi inikeza ijubane elingaphezu kuka-300 km/h.
Ibhethri linomthamo ophelele wama-82 kWh, anele imijaho ye-sprint ephakathi kwemizuzu engama-25 nemizuzu engama-40 ubude. Kodwa-ke, ngobuchwepheshe be-900 V elethwa i-Mission R (800 V ku-Taycan, 400 V kwamanye ama-electrics amaningi) ivumela ukushaja kuze kufike ku-350 kW, okusho ukuthi ime imizuzu engu-15 "ukugcwalisa" ibhethri ukusuka ku-5% ukuya ku-80%.
Oliver Blume, USihlalo Webhodi Eliphethe le-Porsche AG"Njengokuhambisana nokuzibandakanya kwethu ku-Formula E World Championship, manje sesithatha igxathu elikhulu elilandelayo mayelana nokuhamba kukagesi. Lo mqondo uwumbono wethu wemoto yomjaho kagesi yamakhasimende. I-Porsche eqinile: ukusebenza, ukuklama nokusimama."
Kusukela enjinini emaphakathi kuya phakathi nebhethri?
I-Mission R ithatha isilinganiso semoto yezemidlalo ephakathi nenjini, okungukuthi, imoto yezemidlalo enenjini emaphakathi yangemuva, njenge-718 Cayman. Lapha, indawo ebikade isetshenziswa injini yomlilo manje isigcwaliswa ibhethri — singayibiza le Mission R… ibhethri eliphakathi nendawo (ibhethri lisendaweni engemuva emaphakathi)?
Kungakhathalekile ukuthi sikubiza ngani, kuyisixazululo esikuvumela ukuthi ugcine indawo yokushayela ephansi kakhulu - ngokungafani namathremu anamabhethri abekwe phansi kweplatifomu, akhuphule ukuphakama kwegumbi labagibeli - futhi asavumela ukugcina ukulungiswa okulungiselelwe. ukusatshalaliswa kwama-pasta.
Amamotho kagesi amabili abekwe ngqo ezimbazweni zawo; Ngakho-ke iMission R inamasondo amane okushayela. Injini yangaphambili inamandla angu-320 kW (435 hp), kanti engemuva inamandla afinyelela ku-480 kW (653 hp).
Ngokungafani neTaycan, iMission R ayidingi u-gearbox onamagiya amabili futhi ine-ratio eyodwa kuphela. I-Porsche ifakazela isinqumo ngeqiniso lokuthi iningi lemijaho le moto yomncintiswano ihloselwe ukuba nesiqalo, ngakho-ke, asikho isidingo sokwandisa kusukela ekuqaleni.
Ukupholisa… uwoyela
IPorsche ayizange ithathe amathuba. Ukuze kugcinwe ukusebenza okulindelekile kwazo zombili izinjini nebhethri phakathi nomjaho wonke, ukuphathwa okushisayo kwalo lonke iketango le-kinematic kwenziwa ngokupholisa uwoyela okuqondile kumaseli ebhethri kanye ne-electric motor stators.
I-Porsche ithi ngalolu hlobo lokupholisa okuqondile, ngokungafani nezinye izinhlelo zokupholisa uketshezi, kuvumela ukushisa okwengeziwe ukuthi kuhlakazwe, kugcinwe lezi zingxenye ngaphakathi kwewindi lazo elisebenza ngokushisa okushisayo. Lokho okubizwa ngokuthi “derating”, okungukuthi ukuncipha kwamandla ebhethri ngenxa yezimo ezishisayo, kuyaqedwa.
Sekukonke, i-Porsche ithi i-Mission R ifinyelela ukusebenza kwe-on-circuit okulingana ne-Porsche 911 GT3 Cup (992).
Ngemuva kwe-CFRP, i-NFRP
Okusha ku-Porsche Mission R kuhlanganisa nezinye izindaba eziphathelene nokusimama, njengezinto enziwa ngazo. Amaphaneli omzimba, isibonelo, awawona ama-carbon fibre, noma ngokufanele, awawona amapulasitiki aqiniswe nge-carbon fibre noma i-CFRP (ipulasitiki eqiniswe ngekhabhoni).
I-Porsche yasebenzisa olunye uhlobo lwezinto eziyinhlanganisela, enezici zemvelo ezibonakala kakhudlwana: i-NFRP (ipulasitiki eqiniswe ngefayibha yemvelo), noma ipulasitiki eqiniswe ngemicu yemvelo. Kulokhu, le nto ikhiqizwa emicu yefilakisi. Ngaphezu kwamaphaneli omzimba, izakhi ze-aerodynamic (i-spoiler yangaphambili, i-diffuser neziketi ezisemaceleni) kanye nezingxenye eziningi zangaphakathi (umnyango, amaphaneli angemuva nezihlalo) nazo ziku-NFRP.
Izingxenye ze-NFRP azikwazi ukufeza amazinga afanayo wamandla noma ukukhanya njenge-CFRP, kodwa azikho kude: izingxenye ziqine ngokwanele ukuthi zikwazi ukwenza imisebenzi eyingxenye yesakhiwo, zengeza u-10% kuphela esisindweni sengxenye efanayo ye-carbon fiber.
Ngakolunye uhlangothi, i-NFRP ikhiqiza ukukhishwa kwe-CO2 ngaphansi kwama-85% phakathi nokukhiqizwa kwayo kunenqubo efanayo esetshenziselwa i-carbon fiber.
Kodwa-ke, i-carbon fiber isetshenziswa ku-roll cage entsha ehlanganiswe emzimbeni, ayiphazamisi kangako, ilula futhi inikela emotweni encane. Kodwa-ke, imithetho yezemidlalo yezimoto idinga ukuthi i-roll cage yenziwe ngensimbi, kodwa i-Porsche inethemba lokuthi eminyakeni embalwa, lapho sazi inguqulo yokukhiqiza ye-Mission R, imithetho izovumela ukusetshenziswa kwalesi sixazululo.
Ikusasa 718 Cayman?
Ukushiwo okwedlule kwe-718 Cayman bekungelona msulwa. Khumula isudi yomjaho ye-Porsche Mission R futhi sithola umdlalo wezihlalo ezimbili onesilhouette esicishe sifane ne-718 Cayman esiyaziyo.
I-Mission R iwumbono wokuqala wokuthi kungaba yini, noma okungenani ongakulindela ekwakhiweni komlandeli we-718 Cayman. Amahemuhemu azungeze abalandela i-718 Cayman kanye ne-718 Boxster agxile ekutheni hlobo luni lwe-powertrain abazoba nalo, kungaba injini evuthayo noma injini kagesi, ingxoxo i-Porsche ngokwayo eye yaba nayo:
Futhi kunezimpawu eziningi zokuthi lo mqondo ungaba umbono wokuqala womlandeli we-718 Cayman.
Ukuqala ngobukhulu, i-Mission R ibe mfushane ngo-53 mm kune-718 Cayman, imi ku-4326 mm. Kodwa-ke ibanzi kakhulu futhi iphansi, ngokulandelana, i-190 mm (1990 mm) kanye ne-96 mm (1190 mm), kodwa ake sicabange lapha ukuthi, njengoba iseyisibonelo, futhi ngaphezu kwemoto yokuncintisana, "benze ihaba" kakhulu izilinganiso zomphumela omkhulu.
Futhi igama elikhethiwe, elithi Mission R, libonisa amagama akhethelwe izibonelo ezazilindele i-Taycan ne-Taycan Cross Turismo, ngokulandelana, i-Mission E kanye ne-Mission Cross Turismo.
Okokugcina, i-Porsche ayikaze ibambe inkomishi yohlobo olulodwa ngemoto yokuncintisana engaveli emotweni yokukhiqiza. Ingabe i-Mission R ingumbono wekusasa le-718 Cayman? Sikholelwa kanjalo.
