Nimwe mumaheruka gutwikwa gusa kandi niba ari gufunga, ni nurufunguzo rwa zahabu: kurikarita yubucuruzi ya McLaren 765LT hari 765 hp, 2,8 s kuva 0 kugeza 100 km / h na 330 km / h, hiyongereyeho ibice bya Senna kugirango bibe byiza muburyo bwiza.
Nyuma ya 2020 bigoye cyane (reba agasanduku), imwe mu ngero McLaren yizeye ko izakira (ikaba ari nziza cyane mu Bushinwa, guhera ubu mu burasirazuba bwo hagati, mu gihe Uburayi na Amerika bikomeza guhagarara) mubyukuri iyi 765LT. Nubwa gatanu mubihe bigezweho kubirango byabongereza, byubaha F1 umurizo muremure (Longtail), wakozwe na Gordon Murray mu 1997.
Intangiriro yiyi verisiyo ya LT iroroshye kubisobanura: kugabanya ibiro, guhagarikwa byahinduwe kugirango utezimbere imyitwarire yo kugendana, kunoza icyogajuru cyogutwara amababa manini nizuru ryagutse. Ibisobanuro byubahirijwe nyuma yimyaka makumyabiri, muri 2015, hamwe na 675LT Coupé na Spider, hashize imyaka ibiri hamwe na 600LT Coupé na Spider, none hamwe niyi 765LT, ubu muburyo bwa "gufunga" (muri 2021 bizamenyekana guhinduka).
2020, "annus horribilis"
Nyuma yo kwiyandikisha muri 2019 umwaka wagurishijwe neza mu mateka magufi nkuwakoze ibicuruzwa byo mu muhanda, McLaren Automotive yahaniwe cyane mu mwaka w’icyorezo cya 2020, aho abantu batigeze biyandikisha 2700 ku isi yose (-35% ugereranije na 2019), nyuma y’amezi yangiza ubucuruzi , nk'abo yabayeho kuva muri Werurwe kugeza Gicurasi. Isosiyete yavuguruwe mu nzego nyinshi, yagombaga gukusanya inkunga yo hanze (miliyoni 200 z'amadolari ya banki yo mu burasirazuba bwo hagati), igabanya umubare w'abakozi, itanga ingwate y'ibigo bya tekiniki kandi isubika itangizwa ry'icyitegererezo kizaza cya Ultimate Series (Senna, Umuvuduko na Elva) hagati yimyaka icumi.
Ni iki cyahindutse?
Mubintu byateye imbere cyane ugereranije na 720S ishoboye cyane, hariho imirimo ikorwa kuri aerodinamike no kugabanya ibiro, amazina abiri akwiye yimodoka iyo ari yo yose ifite ibyifuzo bya siporo. Mugihe cyambere, iminwa yimbere ninyuma yinyuma ni ndende kandi, hamwe na karuboni fibre hasi yimodoka, ibyuma byumuryango hamwe na diffuzeri nini, bitanga umuvuduko mwinshi wa aerodinamike ugereranije na 720S.
Icyuma cyinyuma gishobora guhindurwa mumyanya itatu, umwanya uhagaze ukaba uri hejuru ya 60mm ugereranije na 720S, usibye kongera umuvuduko wumwuka, bifasha kunoza ubukonje bwa moteri, ndetse nuburyo bwa "feri". ”Bigabanya impengamiro yimodoka" gusinzira "mugihe cya feri iremereye cyane.
Kuba yubatswe kuri base ya 720S, 765LT nayo ifite ibikoresho bya Proactive Chassis Control (ikoresha imashini ihuza imiyoboro ya hydraulic ihura na buri mpera yimodoka, idafite utubari twa stabilisateur) ikoresha ibyuma 12 byiyongera (harimo na moteri yihuta kuri buri ruziga na bibiri ibyuma byerekana imbaraga).
Kubaho kugeza kuri LongTail, ibyangiritse byongerewe
Mubutumwa bwo guta ibiro byinshi bishoboka "hejuru", abajenjeri ba McLaren ntibasize igice na kimwe mubisuzuma.
Andreas Bareis, umuyobozi wa super Series ya McLaren ya Super Series, yansobanuriye ko "hari ibintu byinshi bya fibre fibre ikora mumubiri (umunwa w'imbere, imbere imbere, hasi imbere, amajipo yinyuma, inyuma yinyuma, icyuma cyinyuma ninyuma yinyuma bikaba birebire) , muri tunnel rwagati, hasi yimodoka (yashyizwe ahagaragara) no mubyicaro byamarushanwa; Sisitemu ya gaz ya titanium (-3.8 kg cyangwa 40% yoroshye kuruta ibyuma), F1 ibikoresho byatumijwe hanze bikoreshwa mugukwirakwiza, imbere ya Alcantara imbere, ibiziga bya Pirelli Trofeo R hamwe nipine biroroshye (-22 kg) hamwe na polyakarubone yometse hejuru nko mumodoka nyinshi zo kwiruka. .
Mu kurangiza, kg 80 zaravanyweho, uburemere bwa 765LT bwumye ni 1229 gusa, cyangwa 50 kg ugereranije nuwo bahanganye, Ferrari 488 Pista.
Inyuma ya cockpit na karuboni fibre monocoque ni igipimo cya 4.0 l twin-turbo V8 moteri (hamwe no kuzamuka inshuro eshanu ugereranije na 720S) yakiriye zimwe mu nyigisho za Senna hamwe nibigize kugirango igere kuri 765 hp na 800 Nm (the 720S ifite minus 45 CV na minus 30 Nm na 675LT ukuyemo 90 CV na 100 Nm).
Kubyerekeranye na Senna
Ibisubizo bimwe na bimwe bya tekiniki birashimishije, ndetse no kuba "yarahawe" na Senna yumvikana, nkuko Bareis abisobanura: "twagiye gushaka pisitori ya aluminiyumu ya McLaren Senna, twageze ku muvuduko wo hasi kugira ngo twongere imbaraga hejuru. umuvuduko w'ubutegetsi kandi twateje imbere kwihuta mu muvuduko uri hagati ya 15% ”.
Disiki ya ceramic 765LT nayo yashyizwemo na kaliperi ya feri "yatanzwe" na McLaren Senna hamwe na tekinoroji yo gukonjesha ya Caliper ikomoka kuri F1, hamwe nintererano yibanze yo gusaba munsi ya m 110 kugirango ihagarare burundu kuva umuvuduko wa 200 km / h.
Muri chassis, hanatangijwe iterambere, mubuyobozi hamwe nubufasha bwa hydraulic, ariko nibyingenzi mumitambiko no guhagarikwa. Kurandura ubutaka byagabanutseho mm 5, inzira yimbere yakuze mm 6 naho amasoko aroroha kandi arashimangirwa, bituma habaho umutekano muke no gufata neza nkuko Bareis abivuga: "nukwegera imodoka imbere ukayiha ubugari muri kariya gace, twongera imashini ifata ”.
Iyandikishe mu kanyamakuru kacu
Ikindi kimenyetso kigaragaza agaciro gakomeye k'ibiri muri iyi McLaren 765LT ni bine byahujwe cyane na titanium tailpipes yiteguye gusohora amajwi asiga umuntu wese yumva mumurongo.
Muri Silverstone… ni ibihe byiza?
Urebye ku rupapuro rwa tekiniki byafashije gukaza umurego mbere yo kwinjira mu muzunguruko wa Silverstone, ikindi kintu cyongera umuhango kuri ubu bunararibonye inyuma yiziga rya McLaren: 0 kugeza 100 km / h muri 2.8 s, 0 kugeza 200 km / h kuri 7.0 n'umuvuduko wo hejuru wa 330 km / h, imibare ishoboka gusa byumvikanyweho uburemere / ingufu zingana na 1.6 kg / hp.
Ibihe byo guhatana byemeza ubuhanga bwizi nyandiko kandi niba hafi guhumbya ijisho rimara kwiruka kugera kuri 100 km / h bihwanye nibyo Ferrari 488 Pista, Lamborghini Aventador SVJ na Porsche 911 GT2 RS bagezeho, bimaze kugera kuri 200 km / h bigera kuri 0,6s, 1.6s na 1.3s mbere, uko ari batatu, abo batatu bahanganye.
Nkurikije imbogamizi yimodoka iterwa nibikoresho, ndatahura, iyo mpuye na baquet, akamaro gakomeye ko kuzamura kanseri yo hagati hamwe na kaseti ifatanye kumuryango, kuburyo bishoboka kuyifunga hafi utimuye umubiri. . Hagati ya minimalist dashboard hashobora kubaho 8 "monitor (ndashaka ko irushaho kugana umushoferi, kuko icya cumi cyamasegonda uzunguka kugirango amaso yawe akurikiranwe neza)) ko reka kugenzura imikorere ya infotainment.
Ibumoso, agace gakoreramo hamwe nu kuzenguruka kugirango uhitemo uburyo busanzwe / Siporo / Gukurikirana uburyo bwimyitwarire (Gukemura, aho kugenzura umutekano nabyo bizimya) hamwe na Motorisation (Powertrain) kandi, hagati yintebe, buto kugirango ukore uburyo bwa Launch.
Amatara… kamera… ibikorwa!
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 (bifite kandi ihembe hagati…). Ibikoresho bya gearshift (muri fibre ya karubone) byashyizwe inyuma yimodoka, ibikoresho hamwe nimirongo ibiri ihuza tachometero nini yo hagati (birashoboka guhindura ibyerekanwa). Kumurongo nibindi bisobanuro byinshi, niyo mpamvu icyo ugomba gukora ari ugukoraho buto kugirango igikoresho cyibikoresho kibuze, gihinduka inzira yambere hamwe namakuru asigaye.
Moteri ntabwo ifite cache ya acoustic ya bamwe ba Lamborghini, kurugero, hamwe na crankshaft yayo ituma ijwi ryoroha cyane kandi hamwe na "charisma" nkeya, bishobora kudashimisha bamwe mubashobora kuba bafite.
Birenzeho bose hamwe ni ireme ryimikorere, nubwo intumbero yasigaye kumiterere yimyitwarire kandi sibyinshi mubikorwa byiza. Ahari kuberako 800 Nm ya torque ntarengwa ihabwa buhoro buhoro umushoferi (igiteranyo kiri ku itegeko ryawe saa 5500 rpm), kwihuta ntabwo byunvikana nko gukubita igifu, ariko burigihe bisa nkibikomeza gusunika, muburyo busa nikirere gikomeye cyane. moteri.
Imbaraga zo gufata feri zitanga ibyiyumvo gusa mugihe kigera kuri kimwe cya kabiri "imodoka yo kwiruka" ikora neza, nubwo bikenewe byihutirwa kugabanya umuvuduko. Kuva kuri 300 kugeza 100 km / h, mugihe satani amukubise ijisho, imodoka ikomeza guhingwa, hafi nta nkomyi kandi hamwe nubusa kugirango isobanure inzira igororotse hamwe numushoferi / umushoferi hafi guhagarara kuri pedal ibumoso.
Muburyo bwihuse urashobora kumva ihererekanyabubasha rya misa hanze yu mfuruka, nko muri Woodcote, mbere yo kwinjira kumurongo, aho ugomba kwihangana kugeza igihe ushobora kongera gukandagira kuri moteri yihuse.
Noneho, muburyo bukomeye, nka Stowe kumpera ya Hangar igororotse, urashobora kubona ko 765LT ititaye ku kuzunguza umurizo mu kimenyetso cyibyishimo bya kine niba ubishaka. Kandi ibyo bisaba kwitabwaho hamwe namaboko atajegajega kugirango yongere gukosorwa, hamwe nibikoresho bya elegitoronike nibyingenzi, byibuze kugeza igihe tuzasobanukirwa uburyo "bwo kuyobora inyamaswa" (urashobora gukomeza gukora ibikoresho bya elegitoronike biremewe cyangwa bidahari, nkuko dukusanya impinduka nubumenyi y'inzira n'imodoka iratumira).
Amapine asanzwe, Pirelli Trofeo R, afasha kugumisha imodoka kuri asfalt nk'ikimuga, ariko abadashaka rwose gukubita inzira no kugura 765LT nk'imodoka yo gukusanya kugirango batagendera kuri asfalt ya gisivili barashobora guhitamo Amahitamo ya Zeru. N'ubundi kandi, iyi ntabwo ari Senna, imodoka yo kwiruka ihabwa uruhushya rwo kugenda mu bice rusange.
