Monga McLaren 620R , Mtundu waku Britain unkafuna kupatsa ochepa mwayi mwayi wokwera pamsewu ndi chitsanzo pafupi ndi "championship" 570S GT4 ndikutuluka "pawokha" phazi ndikuyendetsa misewu yapagulu kubwerera kunyumba.
Pokhapokha ndi DNA yochokera ku Fomula 1 momwe mungamvetsetse momwe wopanga magalimoto amsewu ali ndi zaka khumi zamoyo amatha kupanga zodziwika bwino zamasewera omwe ali ndi zaka zoposa theka la Lamborghini kapena Ferrari.
Ndipo iyi ndi njira imodzi yokha yofotokozera mwachidule kayendetsedwe ka msewu wa McLarens wopangidwa kuyambira pomwe mtunduwo unakhazikitsidwanso mu 2011. Makina omwe adatsimikizira, kuyambira tsiku loyamba, kukhala magalimoto oyendetsa bwino kwambiri komanso machitidwe omveka bwino, koma omwe okonda ena ochita zoyipa kumbuyo gudumu likhoza kuyesedwa kuti liwanene kuti ndi "akhalidwe labwino kwambiri."
M'zochitika zoyendetsa galimoto zomwe ndakhala nazo ndi pafupifupi onse a iwo, nthawi zonse ndimawona kuti ndi masewera apamwamba kwambiri komwe kumakhala kosavuta kuti dalaivala wamba azithamanga kwambiri.
Mwina ndichifukwa chake, m'zaka zaposachedwa, kufika kwa Senna ndi 600 LT kwawonjezera sewero loyenera lomwe magalimoto amsewu analibe, kuwapangitsa kukhala oyenerera ngakhale maulendo apamsewu kuposa china chilichonse.
Lembetsani ku kalata yathu yamakalata
Tsopano malingaliro asinthidwa ndipo ndi 620R McLaren uyu ankafuna kupanga njira ya 570 GT4 yomwe yakhala ikuchita bwino mu mipikisano ya GT padziko lonse lapansi, ndi zotsatira zomwe zimadzilankhulira okha: m'chaka chake choyamba, mu 2017 , adapeza maudindo asanu ndi atatu, mizati 24, zipambano 44 ndi ma podium 96 (zopezeka mu 41% ya mipikisano ya GT4 yomwe adasewera).
Kusintha kwakukulu
James Warner, injiniya wamkulu wa McLaren 620R, akufotokoza mwachidule mwambi wa chitukuko cha galimoto latsopano:
"570S GT4 ndiyosavuta kuyendetsa ngakhale ndi madalaivala omwe si akatswiri ndipo tinkafuna kutenga makhalidwe a galimotoyo ndikuwabweretsa kumsewu wa anthu."
McLaren Series
Sport Series, Super Series, Ultimate Series ndi GT ndi momwe McLaren amapangira osiyanasiyana. Zitsanzo ngati 620R, 600LT kapena 570S ndi mbali ya Sport Series; 720S ndi 765LT ndi Super Series; Senna, Elva ndi Speedtail ndi Ultimate Series; ndipo GT ndi, pakadali pano, mlandu wosiyana.
Kodi ntchito imeneyi inakambidwa bwanji?
The 3.8 L amapasa Turbo V8 injini analandira unit kulamulira enieni amene anapereka chitsanzo champhamvu kwambiri mu McLaren Sports Series osiyanasiyana - 620 hp ndi 620 Nm —; ukadaulo wa "Inertia Push" wotengera ukadaulo wa "Inertia Push" (wofotokozedwa ndi Warner, "kuwongolera koyendetsa ndi ma clutch apawiri kumagwiritsa ntchito mphamvu ya chiwongolero cha inertial kuti apange mathamangitsidwe owonjezera panthawi yodutsa" mmwamba "); ndi matayala amtundu wa Pirelli PZero Trofeo R (wokhazikika ndi mtedza umodzi wapakati) ndi otsika pang'ono ndipo adapangidwa makamaka kwa 620R, yomwe idayenera kukhala yolenga pofika "kuyambitsa" zotsalira zonse, monga akufotokozera ndi kunyada kowonekera , bambo anu kuchokera ku engineering:
"620R ili ndi mawilo 19" kutsogolo ndi 20" kumbuyo zomwe zinayambitsa mutu wambiri chifukwa palibe 20" matayala okhwima, koma monga momwe timafunira kuti kasitomala abwere ku njanji ndikusintha Trofeo yomwe amakwera. Pamsewu wapagulu ndikungoyang'ana mwachindunji - osafunikira kusintha kwa chassis - kunali kofunika kuti tipeze matayala enieni. "
Ponena za mwayi wa slicks, ziwerengerozo zikuwunikira: "tinapeza 8% yowonjezera yowonjezera pamwamba ndi 4% yowonjezera yowonjezera, yomwe imatanthawuza phindu la masekondi atatu pa Nardo, dera lathu loyesa mayeso", akumaliza Warner.
Zomwe zimalepheretsa GT4
Ndipo ndi chiyani chomwe chasungidwa ku GT4 ndi zosintha pang'ono kapena zosasintha? Mapiko osinthika a carbon fiber kumbuyo ali ndi mawonekedwe ofanana pamitundu yonse iwiri (ndi 32 cm kutalika kuchokera mthupi, kotero kuti mpweya wotuluka padenga lagalimoto umakhalabe pamtunda wotere, kupewa chipwirikiti kumbuyo) ndipo amakhala ndi atatu. malo osinthika.
Makasitomala amalandira galimotoyo ndi yochepetsetsa kwambiri mwa atatuwo, koma nthawi iliyonse ndizotheka kukonzanso kotero kuti pamene ngodya ikuwonjezeka, kuthamanga kwa aerodynamic pagalimoto kumawonjezekanso, kufika pamtunda wa 185 kg pa 250 km. /H. Kuti agwiritsidwe ntchito m'galimoto yamsewu, choyimitsa choyimitsa chinakhazikitsidwa.
Zina zomwe zimatsimikiziranso za aerodynamics ndi GT4-ngati bumper ndi milomo yakutsogolo yomwe, pamodzi ndi hood yoyamba ya carbon fiber pamtundu wa Sports Series, imathandizira kupanga kuthamanga kwa 65 kg kutsogolo kwa galimoto, yomwe ndi yovuta kwambiri. kuonetsetsa bwino pakati pa kutsogolo ndi kumbuyo kwa McLaren 620R.
Palinso mbiri ya arched kutsogolo kwa mawilo anayi, mpweya wolowa mu hood (momwe chisoti kapena chikwama choyendera chimakwanira kumapeto kwa sabata) ndi (ngati mukufuna) mpweya wodutsa padenga, pamenepa kuti mukondweretse. inlet engineering ndikukweza sewero lamayimbidwe mu cockpit.
Pa chassis, McLaren 620R imathandizidwa ndi makina osinthira pamanja m'malo 32 a msonkhano wamasika-on-damper (ma coilovers, omwe amafanana ndi galimoto yothamanga), yokhala ndi zosintha zodziyimira pawokha pakuponderezana ndi kukulitsa, komwe ndi 6 kg kupepuka. pogwiritsa ntchito ma triangles a aluminiyumu) kusiyana ndi njira yosinthira damping yomwe imagwiritsidwa ntchito mu 570S - kasitomala akhoza kusankha, mwachisawawa, kuphatikiza makina onyamula mphuno yagalimoto kuti apeze / kutuluka m'magalasi, phula loyipa, ndi zina).
Poyerekeza ndi 570S, mipiringidzo ya stabilizer, akasupe ndi zitsulo zapamwamba (mu zitsulo zosapanga dzimbiri osati mphira) zimakhala zolimba, pamene mabuleki asinthidwa ndi ma discs a ceramic - 390 mm kutsogolo ndi 380 mm kumbuyo, motero amakulirakulira. kuposa a GT4) ndi ma calipers okhala ndi ma pistoni asanu ndi limodzi mu aluminiyamu yonyezimira kutsogolo ndi zinayi kumbuyo, kuwonjezera pa chowonjezera cha brake ndi pampu ya vacuum yoperekedwa ndi McLaren Senna.
Mkati wonunkhira bwino
Mawonekedwe amkati amkati amatsimikizira kuti kasitomala wa 620R ndi ndani (pali ma Brits ochulukirachulukira omwe ali ndi supersports akutenga "zidole" zawo kumapeto kwa sabata, monga tafotokozera McLaren), komanso zolinga ziwiri za izi. Mwachitsanzo, monga ma bacquet amtundu wa ultra-light fiber amaphatikizira malamba "wamba" komanso malamba apadera othamanga, kapena mahatchi, okhala ndi mfundo zisanu ndi imodzi.
Pali Alcantara paliponse komanso mpweya CHIKWANGWANI, nthawi zambiri structural, monga m'dera la pakati kutonthoza olumikizidwa kwa nsana wa galimoto, chidutswa chimodzi (Monocell II) kwathunthu mu mpweya CHIKWANGWANI, monga onse McLarens (determinant). chifukwa cha nthenga zake zowuma 1282 kg mu nkhani iyi, pafupifupi 200 makilogalamu zosakwana Mercedes-AMG GT).
Zoyatsira mpweya, zipinda zamagalavu ndi zotchingira pansi pa oyenda pansi ndizosankha popanda mtengo, pomwe kasitomala amathanso kusankha makina omvera omwe ali ndi siginecha ya Bowers & Wilkins… anaikidwa kuseri kwa cockpit.
Pakatikati pa dashboard ya minimalist pakhoza kukhala 7 "monitor (ndikufuna kuti ikhale yolunjika kwa dalaivala, chifukwa chakhumi chilichonse cha sekondi iliyonse yomwe imapezeka kuti muyang'ane pamsewu ndi yolandiridwa ...) kuwongolera ntchito za infotainment.
Kupitilira apo, pakati pa mipando, malo ogwirira ntchito okhala ndi zowongolera zozungulira posankha mitundu ya Normal/Sport/Track for Behavior (Kusamalira, komwe kuwongolera kukhazikika kumazimitsidwa) ndi Motorization (Powertrain) komanso batani loyambitsa Launch mode ndi yambani/yimitsani… kuti mupulumutse mafuta. Kulondola…
mukhoza kukhala panjira
Gawo loyamba la zochitika zoyendetsa galimoto za McLaren 620R zidachitika m'misewu ya Norfolk, kumpoto chakum'mawa kwa England, kotero kuti zinali zotheka kumvetsetsa kuti kutembenuka kwa GT4 kukhala "civil" kunali kotani. zotsatira.
Ndinayamba ndikuwona maonekedwe abwino kunja (chifukwa cha kuphatikizika kwa galasi lalikulu lokhala ndi zipilala zopapatiza), nditangodzikhazikitsa ndekha ndi (re) kudziwa zowongolera zazikulu.
Kuwoneka bwino kwachiwiri kunali kokhudzana ndi kuyimitsidwa koyenera kwa kuyimitsidwa, ndi makina a McLaren akuyika pafupi ndi imodzi mwazosintha bwino za 32 zomwe mungasankhe.
Ndimayesetsa kusintha malo osankhidwa a "H" (Kugwira) kuti ndiwonetsetse kuti palibe kusintha kwa malamulo (ndi buku, osati lamagetsi), mosiyana ndi zomwe zimachitika ndi "P" (Powertrain) selector, yomwe zimakhudza kuyankha kwa injini, yomwe ili yamphamvu kwambiri kuposa ya GT4 (pafupifupi 500 hp), chifukwa cha zoletsa zomwe zimayikidwa chifukwa chofuna kulinganiza mphamvu ndi mpikisano.
Mosadabwitsa, mathamangitsidwe akudodometsa ndipo kupitilira misewu yokhala ndi njira imodzi mbali zonse kumatha kuthetsedwa pomwe mdierekezi akusisita diso, ndi phokoso la injini lomwe silimalamula ulemu wocheperako, mosiyana.
Chiwongolerocho ndi chodabwitsa kwambiri komanso cholankhulana, mofanana ndi momwe mabuleki amawonekera kuti amatha kusokoneza galimoto nthawi yomweyo pamene tikuyendetsa momasuka, kapena sanakonzekere kuyimitsa 620R kuchokera ku liwiro la ballistic.
mchere wonyezimira
Ndikafika kudera la Snetterton kuti ndikawonere njanjiyo ndipo ngakhale sindikumva kusinthidwa nthawi yomweyo kukhala dalaivala, sipayenera kukhala kukayikira kulikonse.
Kusintha galimoto, kukhala ndi matayala okhwima mokwanira, kumangopangidwa kuti zifulumizitse ndondomekoyi, chifukwa nditha kutsimikiziridwa kuti msewu ndi magalimoto amafanana ndi ofanana, kupatulapo makonda osiyanasiyana. Kuyimitsidwa komwe kumapangidwa pa chotsitsa chododometsa chokha (pakati pa 6 mpaka 12 kudina molimba kuposa galimoto yomwe ndidangoyendetsa pamsewu, ndiye kuti, 25% "yowuma") ndi mapiko akumbuyo (omwe adakwezedwa pamalo apakati, ndikuwonjezera Kuthamanga kwa aerodynamic kumbuyo ndi pafupifupi 20%).
Pafupi ndi ine, monga mphunzitsi woyesera moto, ndi Euan Hankey, woyendetsa galimoto wa ku Britain wodziwa bwino yemwe ali ndi malo amodzi, Porsche Cup ndi GT racing, posachedwapa ndi McLaren, yemwe ndi woyendetsa mayeso, komanso kupikisana nawo Championship. British GT, komwe amalumikizana ndi mayi, Mia Flewitt, wokwatiwa ndi CEO wa McLaren Automotive. Zogwirizana bwino, choncho.
Ndili ndi malingaliro abwino, mwina chifukwa cha chigonjetso chake pa mpikisano wa GT masiku angapo m'mbuyomo, Hankey amandithandiza kuyika cholankhulira pa chisoti changa ndikundipatsa malingaliro angapo a zomwe zinali kubwera.
Ndikalowa mu bacquet, ndimazindikira kuti kuchepa kwa kuyenda komwe kumachitika chifukwa cha harni kumapangitsa kuti ikhale yothandiza kwambiri kukweza kontrakitala wapakati komanso lamba lomwe limalumikizidwa pachitseko, kotero kuti ndizotheka kutseka pafupifupi osasuntha thupi. Pakati pa chala chachikulu ndi zala zina zinayi (zotetezedwa ndi magolovesi) m'dzanja lililonse ndili ndi chiwongolero chopanda mabatani kumaso! Zomwe zimangogwira ntchito zomwe zidapangidwa poyambirira: kutembenuza mawilo (inde, ilinso ndi nyanga pakati…).
"116 m kuchoka pa 200 km/h kufika pa 0 ndi 12 m kuchepera pa 570S"
Zotengera zazikulu za gearshift zimayikidwa kuseri kwa chiwongolero (chowuziridwa ndi omwe amagwiritsidwa ntchito mu F1's ndi mu carbon fiber), zida zokhala ndi ma dials awiri ozungulira tachometer yayikulu yapakati (ndizotheka kusinthasintha mawonekedwe, monga momwe ziliri pama digito amakono) .
Timagwiritsa ntchito masinthidwe akulu kwambiri a njanji (makilomita 4.8) ndipo, monga mwachizolowezi, ndikusintha kuchoka pamiyendo pang'onopang'ono kupita kwa ena mwachangu pang'ono, kugwiritsa ntchito mwayi wodziwa zambiri zamagalimoto ndi njanji (16 laps). kutanthauza makilomita opitilira theka la mazana a ma kilomita pamayimbidwe "wotanganidwa kwambiri".
Chiwongolero ndi chofulumira momwe chiyenera kukhalira, ndipo mkombero waung'ono wophimbidwa ku Alcantara umathandizira kuti ugwire bwino. Hankey samatopa kupereka malangizo amayendedwe oyenera kwambiri ndikusintha nthawi iliyonse padera ndikumwetulira ndikapepesa chifukwa chomwe chimanditengera kuloweza njirayo, ndikuwongolera njira ziwiri zazikulu ndi (12) zokhota pazokonda zonse, kuvomereza izi. "ndizoposa zachilendo kwa munthu yemwe si katswiri woyendetsa galimoto".
Kunena kuti kuyendetsa galimoto kungakhale kodabwitsa kungakhale kosafunika komanso koonekeratu, koma ndiyenera kunena.
Seveni-liwiro wapawiri-clutch automatic gearbox anapangidwa ndi McLaren a pulogalamu yake kuti mofulumira osati kugwetsa pang'ono maboma V8, amene sadziwa za kuchedwa kuyankha, ngakhale kuganizira kuti 620 Nm torque pazipita amangopanga. ife mochedwa (pa 5500 rpm). Mulimonsemo, kuchokera pamenepo kupita ku redline - pa 8100 rpm - pali zambiri zoti mufufuze.
kusokoneza maganizo
Chimodzi mwa zinthu zochititsa chidwi za McLaren 620R ndi mphamvu yake braking, onse mtunda ndi mmene ndondomeko ikuchitika. 116 m kuchoka pa 200 km/h kufika pa 0 ndi 12 m kuchepera pa 570S yomwe ili kale ndi kaundula.
Ndipo ichi chinali chinthu chomwe chinawonekera kumapeto kwa mapeto molunjika, pamene tinafika pamwamba pa 200 km / h ndipo ziribe kanthu kuti ndimalowa bwanji m'mutu mwanga kuti pamphuno yotsatira ndiyambe kuswa pambuyo pake, nthawi zonse ndinkatha kupeza. patali ndi poyambira.
Njira yokhayo inali kudzutsanso ndikukhumudwitsa kunyada… ndi kuseka kwa Hankey kumbuyo. Koma momwe mabuleki agalimoto amathamangitsiranso zida: ngakhale, m'malo mwake, idafika pobowola mwachangu, nthawi zonse zinali zotheka kulumpha mabuleki ndikutembenuza chiwongolero, ndipo McLaren sanazengereze kumvera awiriwo. malangizo ndi luso lofanana.
Pambuyo pa theka la ola la kugwiritsira ntchito pang'onopang'ono kwambiri, mabuleki adakhala oyenerera utumiki wonse komanso osatopa kwambiri kuposa dalaivala uyu, yemwe, pamapeto a phunzirolo, adawonetsa kale zizindikiro za kutopa, yemwe amapachikidwanso. akatswiri anapepesa potsimikizira kuti anzake ena dzulo lake ankafunikanso kuti amwe madzi akadali m'galimoto, kumapeto kwa gawoli.
Kupirira mathamangitsidwe motsatizanatsatizana ndi mosalekeza ndi mabuleki a mtundu uwu kumafuna kukonzekera kokulirapo, ngakhale mutakhala ndi mphindi zoseweretsa pakati, mochuluka kapena mocheperapo mwadala.
ifika liti komanso imawononga ndalama zingati
The McLaren 620R adzakhala ndi kupanga okha makope 225, ndi chiyambi cha malonda analengeza kumapeto kwa 2020. Mtengo, ife tikuyerekeza, ndi 400 mayuro zikwi Portugal, poganizira mtengo boma la 345 500 mayuro ku Spain ndi kuchokera ku 300 000 euros ku Germany.
