Nk McLaren 620R , ikirango cyabongereza cyashakaga guha abanyamahirwe bake amahirwe yo kugendera kumuhanda hamwe nicyitegererezo cyegereye "championat" 570S GT4 hanyuma bagasohoka "bonyine" no gutwara mumihanda nyabagendwa murugo.
Gusa hamwe na ADN ifite inkomoko muri Formula 1 umuntu arashobora kumva uburyo uruganda rukora imodoka zo mumuhanda rufite imyaka icumi yubuzima rushobora kumvikanisha ibirango byiza bya siporo bifite igice kirenga igice cyikinyejana nka Lamborghini cyangwa Ferrari.
Kandi ubu ni bumwe mu buryo bwo kuvuga mu ncamake ibinyabiziga byo mu muhanda McLarens yakoze kuva aho imurikagurisha ryatangiriye mu mwaka wa 2011. Imashini zagaragaje, guhera ku munsi wa mbere, kuba imodoka za siporo zifite imikorere myiza kandi ikora neza, ariko kuri bamwe mu bakundana babi inyuma ya ibiziga birashobora gushukwa kubashinja "kwitwara neza."
Muburambe bwo gutwara ibinyabiziga nagize hafi yabose, burigihe mbona ko ari siporo ya kalibiri ndende aho byoroshye kubashoferi basanzwe kugenda byihuse.
Ahari niyompamvu ariyo mpamvu, mumyaka yashize, ukuza kwa Senna na 600 LT byongeyeho ikinamico ikwiye imodoka zo mumuhanda zabuze, bigatuma zikwiranye ningendo zo mumuhanda kuruta ibindi.
Iyandikishe mu kanyamakuru kacu
Noneho logique yarahinduwe kandi hamwe niyi 620R McLaren yashakaga gukora verisiyo yumuhanda wa 570 GT4 yitwaye neza mumarushanwa ya GT kwisi yose, hamwe nibisubizo byivugira: burimwaka wambere, muri 2017, yakusanyije imitwe umunani, inkingi 24, intsinzi 44 na podium 96 (yagezweho muri 41% mumarushanwa ya GT4 yakinnye).
Impinduka nyamukuru
James Warner, injeniyeri mukuru wa McLaren 620R, yavuze muri make intego yo guteza imbere imodoka nshya:
"570S GT4 biroroshye gutwara ndetse n'abashoferi badafite umwuga kandi twifuzaga gufata ibiranga irushanwa no kubizana ahantu nyabagendwa."
Urutonde rwa McLaren
Imikino, Urukurikirane rwibihe, Ultimate Series na GT nuburyo McLaren yubaka urwego rwayo. Moderi nka 620R, 600LT cyangwa 570S ni igice cya Siporo; 720S na 765LT ni Super Series; Senna, Elva na Speedtail ni Ultimate Series; na GT ni, kuri ubu, urubanza rutandukanye.
Nigute, mubikorwa, ubu butumwa bwakurikijwe gute?
Moteri ya 3.8 l twin-turbo V8 yakiriye igice cyihariye cyo kugenzura cyatanze urugero rukomeye mumikino ya siporo ya McLaren - 620 hp na 620 Nm -; ubwikorezi bwihuta burindwi bwakoreshejwe bwa tekinoroji ya "Inertia Push" (byasobanuwe na Warner, "imiyoborere yimodoka hamwe nimbaraga ebyiri zikoresha imbaraga zumubyigano udafite imbaraga kugirango habeho kwihuta mugihe cyo gutambutsa" umwe hejuru "); n'amapine ya Pirelli PZero Trofeo R (ashyirwaho numutobe umwe wo hagati) ni kimwe cya kabiri kandi yatunganijwe byumwihariko kuri 620R, yagombaga guhanga mugihe cyo "guhimba" ibice byuzuye, nkuko abisobanura afite ishema rigaragara, so avuye mubuhanga:
“620R ifite ibiziga 19” imbere na 20 ”inyuma byateje umutwe cyane kuko nta tine ya 20” ihari, ariko nkuko twifuzaga rwose ko umukiriya yaza inzira agahindura Trofeo yari atwaye kumuhanda nyabagendwa unyuze gusa kubisimbuza mu buryo butaziguye - bitabaye ngombwa ko hahindurwa chassis - byari ngombwa ko tubona amapine yihariye. ”
Ku bijyanye n'inyungu za slicks, imibare iratangaza: "twageze kuri 8% hejuru yubusabane hamwe na 4% bifata impande zose, bivuze ko twunguka amasegonda atatu kuri lap kuri Nardo, ibipimo byacu byo gupima", Warner.
Niki kibuza GT4
Kandi niki cyabitswe muri GT4 hamwe nimpinduka nke cyangwa ntagahinduka? Ibaba ryinyuma rya karubone rishobora guhindurwa rifite imiterere imwe kuri moderi zombi (ni cm 32 z'uburebure kuva mumubiri, kuburyo umwuka uva mumisenge yimodoka uguma kuri urwo rwego rwo hejuru, ukirinda akaduruvayo inyuma) kandi ufite bitatu imyanya ishobora guhinduka.
Umukiriya yakira imodoka hamwe na moderi iringaniye muri bitatu, ariko umwanya uwariwo wose birashoboka gukora ubugororangingo kuburyo uko inguni yiyongera, umuvuduko wa aerodynamic kumodoka nawo uriyongera, ukagera kuri kg 185 kuri 250 km / H. Kugirango ishobore gukoreshwa mumodoka yo mumuhanda, hafashwe itara ryo guhagarara.
Ibindi bintu byingenzi mubijyanye na aerodinamike ni GT4 imeze nka bumper hamwe niminwa yimbere, hamwe na fibre ya karubone ya mbere kuri moderi ya siporo, ifasha gukora umuvuduko wa kg 65 imbere yimodoka, ibyo bikaba ari ngombwa kugirango habeho kuringaniza imbere n'inyuma ya McLaren 620R.
Hariho kandi imyirondoro yimbere imbere ya buri ruziga rune, gufata ikirere muri hood (munsi yingofero cyangwa igikapu cyurugendo gihura na wikendi) hamwe numuyoboro windege (utabishaka) hejuru yinzu, muriki gihe kugirango ubone ubutoni inlet engineering mugihe uzamura ikinamico acoustic muri cockpit.
Kuri chassis, McLaren 620R itangwa na sisitemu yo guhinduranya intoki mumwanya 32 winteko-yimvura (coilovers, isanzwe yimodoka yo gusiganwa), hamwe noguhindura kwigenga no kwikuramo, bikaba byoroheje 6 kg (by ukoresheje inyabutatu ya aluminiyumu) kuruta sisitemu yo guhuza imiterere ikoreshwa muri 570S - umukiriya arashobora kuyihitamo, kubishaka, guhuza sisitemu yo kuzamura izuru ryimodoka kugirango igere / isohoka muri garage, asfalt mbi, nibindi).
Ugereranije na 570S, utubari twa stabilisateur, amasoko hamwe no hejuru hejuru (mubyuma bitagira umuyonga kandi ntabwo ari reberi) birakomeye, mugihe feri yatunganijwe hamwe na disiki ya ceramic - mm 390 imbere na mm 380 inyuma, bityo ikaba nini kuruta irenze iya GT4) hamwe na kaliperi hamwe na piston esheshatu muri aluminiyumu yahimbwe imbere na bane inyuma, hiyongereyeho feri ya feri na pompe vacuum yatanzwe na McLaren Senna.
Imikino ihumura imbere
Ikirere cya spartan yimbere cyemeza umwirondoro wumukiriya wa 620R (hariho Abongereza benshi hamwe na supersports bajyana "ibikinisho" byabo muri wikendi, nkuko twabidusobanuriye i McLaren), ariko kandi intego ebyiri zibi icyitegererezo, nkibikoresho bya ultra-yoroheje ya karubone fibre ihuza imikandara ya "gisivili" hamwe nu mukandara udasanzwe wo gusiganwa, cyangwa ibikoresho, hamwe nibintu bitandatu byo gukosora.
Hano hari Alcantara hose kandi na fibre ya karubone, mubihe byinshi byubatswe, nko mukarere ka konsole hagati ihuza umugongo wimodoka, igice kimwe (Monocell II) rwose muri fibre ya karubone, nko muri McLarens yose (determinant) kuburemere bwayo, kg 1282 yumye muriki gihe, hafi 200 kg munsi ya Mercedes-AMG GT).
Icyuma gikonjesha, uturindantoki hamwe na cockpit hasi bitwikiriye kubusa nta kiguzi, mugihe umukiriya ashobora kandi guhitamo sisitemu ya majwi ya premium hamwe n'umukono wa Bowers & Wilkins… nubwo ashidikanya ko ishobora kurenga amajwi yerekana Bi-turbo V8. yashyizwe inyuma ya cockpit.
Hagati ya minimalist dashboard hashobora kubaho monitor ya 7 ”(ndashaka ko irushaho gushishikarira umushoferi, kuko icya cumi cyamasegonda yunguka kugirango uhore uhanze amaso mumuhanda biremewe…) bikwemerera kugenzura imikorere ya infotainment.
Hasi hepfo, hagati yintebe, agace gakoreramo hamwe nubugenzuzi bwo guhitamo uburyo busanzwe / Siporo / Track yuburyo bwimyitwarire (Gukemura, aho igenzura rihamye naryo rizimya) na Motorisation (Powertrain) kandi na buto yo gukora Launch mode na gutangira / guhagarika… kubika gaze. Iburyo…
urashobora gutura mumuhanda
Igice cya mbere cyuburambe bwo gutwara bwa McLaren 620R cyabereye mumihanda yo mukarere ka Norfolk, mumajyaruguru yuburasirazuba bwUbwongereza, kuburyo byashobokaga kumva intera ihinduka rya GT4 kuri "civil" ryifuzaga. Ingaruka.
Natangiye mbona neza neza hanze (bitewe ningaruka zifatika zumuyaga mugari hamwe ninkingi zifunganye), ako kanya nyuma yo kwishyiriraho ubwanjye na (re) nkamenyera kugenzura nyamukuru.
Icyerekezo cya kabiri cyiza cyari gifitanye isano nubushobozi bwo guhagarikwa bushyize mu gaciro, hamwe nabakanishi ba McLaren babishyira hafi yimwe muburyo bwiza bwa 32 bwo guhitamo.
Ndagerageza guhindura imyanya yuwatoranije "H" (Handling) kugirango gusa menye neza ko rwose nta gihinduka mumabwiriza (ni intoki, ntabwo ari elegitoronike), bitandukanye nibibaho hamwe nuwatoranije "P" (Powertrain), aribyo bigira ingaruka ku gisubizo cya moteri, ifite imbaraga zirenze iz'i GT4 (hafi 500 hp), kubera inzitizi zashyizweho no gukenera guhuza imbaraga n'amarushanwa.
Ntabwo bitangaje, kwihuta birazunguruka kandi kunyura mumihanda ifite umurongo umwe muri buri cyerekezo birashobora kurangira mugihe satani akubise ijisho, hamwe nijwi rya moteri ritegeka kutubaha, muburyo bunyuranye.
Imiyoboro irihuta cyane kandi ivugana, muburyo feri isa nkaho ishobora guhagarika imodoka hafi ako kanya mugihe tugenda ahantu horoheje, cyangwa tutiteguye guhagarika 620R kumuvuduko wa ballistique.
abarya ibimenyetso
Ngeze kumuzunguruko wa Snetterton kuburambe kandi nubwo ntumva mpita mpinduka umushoferi, ntihakagombye kubaho gushidikanya.
Guhindura imodoka, kuri imwe ifite amapine yuzuye neza, yakozwe gusa kugirango yihutishe inzira, kuko ndashobora kwizeza ko umuhanda n'umuhanda bikurikirana, usibye ibice bitandukanye. Ihagarikwa ryakozwe kuri sisitemu yo kwikuramo ubwayo (gukanda hagati ya 6 kugeza 12 gukanda kurenza imodoka natwaye mumuhanda, ni ukuvuga 25% "yumye") hamwe numwanya winyuma winyuma (wazamuwe kumwanya muto, wongera kuri ingufu za aerodinamike inyuma hafi 20%).
Iruhande rwanjye, nk'umwigisha w'ikizamini cy'umuriro, ni Euan Hankey, umushoferi w'umwongereza w'inararibonye ufite imyanya imwe mu myanya imwe, Porsche Cup na GT gusiganwa, vuba aha hamwe na McLaren, akaba ari umushoferi w'ikizamini, ndetse no kwitabira Shampiyona. GT yo mu Bwongereza, aho afatanya n’umudamu, Mia Flewitt, yashakanye n’umuyobozi mukuru wa Automotive ya McLaren. Bifitanye isano rero.
Muburyo bwiza, ahari kubera intsinzi ye mumarushanwa ya GT muminsi mike ishize, Hankey amfasha gushyira umuvugizi kumutwe wanjye kandi ampa ibitekerezo bike kubizaza.
Iyo mpuye na bacquet, menya ko kugarukira kwimodoka iterwa nicyuma bituma biba byiza cyane kuzamura kanseri yo hagati ndetse nigitambara gifatanye numuryango, kuburyo bishoboka kuyifunga hafi utimuye umubiri. Hagati y'urutoki n'izindi ntoki enye (zirinzwe na gants) muri buri kuboko mfite ibizunguruka bidafite buto mumaso! Bikaba bikora gusa mubyaremwe mbere: guhindura ibiziga (yego, ifite n'ihembe hagati…).
"116 m kuva kuri 200 km / h kugeza kuri 0 ni 12 m munsi ya 570S"
Imashini nini ya gareshift yashyizwe inyuma yimodoka (ihumekwa nizikoreshwa muri F1 no muri fibre ya karubone), ibikoresho hamwe nimirongo ibiri ihuza tachometero nini yo hagati (birashoboka guhindura ibyerekanwa, nkuko bisanzwe mubisanzwe kuri terefone ya none) .
Twifashishije ibinini binini byumuhanda (4.8 km) kandi, nkuko bisanzwe, ndimo ndahindukira mva mumaguru ahantu haciriritse kugera kubandi byihuse, nkoresha umurwa mukuru wubumenyi bwakusanyirijwe mumodoka n'inzira (16 lap bivuze ibirometero birenga magana kuri injyana "yihuta".
Kuyobora birihuta nkuko bikenewe, kandi uruzitiro ruto rutwikiriye Alcantara rufasha kubona neza. Hankey ntajya arambirwa no gutanga amabwiriza yinzira nyabagendwa hamwe nimpinduka kuri buri mwanya kumuzunguruko no kumwenyura iyo nsabye imbabazi kumwanya byantwaye gufata mu mutwe inzira, hamwe n'imirongo ibiri minini kandi (12) umurongo kuburyohe bwose, ukemera ko “Birarenze ibisanzwe ku muntu utari umushoferi wabigize umwuga”.
Kuvuga ko injyana yo gutwara ibinyabiziga ishobora kuba igitangaza irashobora kuba ikirenga kandi igaragara cyane, ariko ngomba kubivuga.
Imashini yihuta ya karindwi yihuta yakozwe na software ya McLaren kugirango yihute kandi itagabanuka na gato mubutegetsi bwa V8, butazi gutinda kubisubizo, ndetse urebye ko 620 Nm yumuriro mwinshi ukora gusa twe ugereranije natinze (kuri 5500 rpm). Ibyo ari byo byose, kuva aho kugeza gutukura - kuri 8100 rpm - haracyari byinshi byo gushakisha.
gufata feri
Kimwe mu bintu byemeza cyane imbaraga za McLaren 620R nubushobozi bwa feri, haba mumwanya ndetse nuburyo inzira igenda. M 116 m kuva kuri 200 km / h kugeza 0 ni 12 m munsi ya 570S isanzwe ifite igitabo cyihariye.
Kandi iki cyari ikintu cyagaragaye nyuma yo kurangiza neza, aho twageze hejuru ya 200 km / h kandi uko ninjiye mumutwe wanjye ko kumurongo ukurikira natangira gufata feri nyuma, burigihe narangije kubona kure yintangiriro. ya trayectory kugirango ikore hejuru yumurongo.
Igisubizo cyonyine kwari ugusubiramo no kubabaza ubwibone… hamwe no gusetsa Hankey inyuma. Ariko uburyo feri yimodoka nayo yambura intwaro: niyo mugihe, kurundi ruhande, yageze aho feri yihuta, buri gihe byashobokaga gusimbuka kuri feri no guhindura moteri, kandi McLaren ntiyigeze yanga kumvira byombi amabwiriza afite ubushobozi bungana.
Nyuma yisaha irenga igice cyisaha yo gukoresha buhoro buhoro, feri byagaragaye ko ibereye serivise yose kandi irushye cyane kurenza uyu mushoferi, arangije isomo, yamaze kwerekana ibimenyetso byerekana umunaniro, wongeye kumanika. we wabigize umwuga yasabye imbabazi yizeza ko hari abandi bakorana ejobundi bari bakeneye kwakira amazi mu modoka, isomo rirangiye.
Kwihanganira kwihuta no gukomeza kwihuta no gufata feri ya kalibiri bisaba kwitegura cyane, kabone nubwo haba hari ibihe byo gukina hagati, byinshi cyangwa bike kubushake.
bigeze ryari kandi bingana iki
McLaren 620R izaba ifite umusaruro ugarukira kuri kopi 225, hamwe no gutangira kwamamaza byatangajwe mu mpera za 2020. Igiciro, turagereranya, ni ibihumbi 400 by'amayero kuri Porutugali, urebye igiciro cyemewe cya 345 500 muri Espagne na kuva 300 000 euro mubudage.
