Imirongo yanyuma yumurimo wumuziki watsinze igomba kuba idasanzwe. Kandi nkuwahimbye ibyamamare byose, BMW irabizi neza kuko ikintu gisa nacyo gifata ukuri kumodoka, nimwe mumpamvu zituma havuka BMW M2 CS.
Niba umusaruro wicyitegererezo urangiye hamwe na verisiyo iciriritse, icyo nikintu gihinduka nkibikoresho rusange hamwe nudukoko ku kirahure kirangiye urugendo rwibiruhuko.
BMW M2 CS rero irerekana iherezo rya 2 Series (mugihe cyumwaka uza igisekuru gishya). Niba ubyibuka, ubu bifite igice kinini cyurwego rutangwa na platifomu yimbere yimodoka, nyamara, muriki gikorwa cyumubiri cyakomeje kuba umwizerwa kumahame yikimenyetso cya Bavariya, kubo imodoka za siporo zigomba kwitwara neza. gusunikwa ninziga zinyuma kandi ntizikururwa niziga ryimbere.
icyitegererezo kitigeze kibaho
Ndetse urebye ko hariho Irushanwa rya M2 (rikoresha moteri imwe, ariko hamwe na 40 hp munsi ariko 550 Nm), abajenjeri b'Abadage bifuzaga kuzamura umurongo kurushaho.
Iyandikishe mu kanyamakuru kacu
Nkuko rero, nkuko Markus Schroeder, umuyobozi wuyu mushinga abidusobanurira, ni ubwambere havutse urukurikirane ruto rwimodoka ya BMW yoroheje (yavuzwe bwa mbere ibice 75 gusa ariko birashoboka ko bizarenga ibyo, ukurikije uko ushaka kubyitwaramo ubu mugutangiza).
Nk’uko Schroeder abivuga, “M2 CS irazamura ibahasha ifite imbaraga zasabwe n'irushanwa rya M2 kugira ngo ishimishe ubwoko bw'abakiriya badasanzwe ariko busaba abantu bakunda kwinjira mu nzira”.
Muyandi magambo, muburyo bwihariye, aho kurandura icya cumi cyamasegonda kuri lap buri gihe ushakishwa nkaho ari Grail Yera, bityo rero bikaba byumvikana ko umuyobozi usanzwe, udasize asifalti rusange, bitazashoboka. gushobora kubona bifite agaciro.
"Icyo nshaka kuri" fibre fibre
Nibwo rero, CS ya mbere ya M2 (hariho CS muri M3 na M4) kandi ikora nk'ishingiro ryimodoka ya BMW, ikintu kitoroshye kubyizera hamwe nikinamico ishimangira imirongo nibigize.
Reka duhere kumubiri wiyi BMW M2 CS: iminwa yo hepfo ya bamperi yimbere, bonnet (ipima kimwe cya kabiri nkirushanwa kandi irimo umwuka mushya) hamwe numwirondoro wa aerodynamic (Gurney) uzamuka hejuru yumupfundikizo wa ivarisi ni shyashya.
Fibre ya karubone iri hose.
Kimwe na diffuzeri munsi ya bamperi yinyuma, ibyo bintu byose bikozwe muri fibre ya karubone, kandi mubihe byose, ultra-light na ultra-rigid material ihura nurwego runini cyangwa ruto.
Intego yibi bintu ni ukongera ingufu za aerodynamic hamwe numuyoboro wumuyaga hafi no munsi yimodoka, kugabanya imvururu.
Gukoresha fibre ya karubone byatewe no gushaka kugabanya ibiro. Igishimishije, M2 CS ipima gato gato kurushanwa (“munsi ya 40 kg”, nk'uko Schroeder abivuga) kuri kg 1550.
Agaciro kanini, sibyo kuko guhagarika imihindagurikire y'ikirere byongera uburemere ugereranije na "pasive" ya murumuna wa interineti. Byose kuko BMW yahisemo kudakora imodoka ikabije.
Niba ibyo byari intego yibanze, byari kuba byoroshye gukora udafite umurongo wintebe zinyuma, icyuma gikonjesha cyangwa sisitemu y'amajwi. Kubwibyo, kwiyongera kwibice bya fibre karubone no kugabanya ibikoresho bya acoustic insulaire ya cabine ntabwo bihagije kugirango "indyo" ikaze.
Moteri yo guhuza
Hamwe na silinderi esheshatu kumurongo, 3.0 l na (hano) 450 hp, iyi moteri ifite ibikoresho byiza bya BMW yubuhanga: kuva turbos ebyiri za mono-umuzingo, kugeza inshinge zisobanutse neza, kugeza kuri sisitemu yo guhindura ibintu (Valvetronic) ) cyangwa Vanos crankshaft (inlet na gaze), ntakintu kibura.
Nubwo bimeze bityo, kugabanya ubwoba bwibiro bivuze ko BMW M2 CS idakora neza kurenza irushanwa rya M2 ridafite imbaraga nkeya mubikorwa.
Ibyo byavuzwe, hamwe na garebox yihuta itandatu (iyambere kuri BMW ifite izina rya CS) 100 km / h igera muri 4.2 s, mu yandi magambo, inyandiko imwe nki Amarushanwa hamwe nogukwirakwiza byikora hamwe na M DCT ebyiri. .
Iyo ifite iyi garebox, BMW M2 CS ibona igihe kiva kuri 0 kugeza 100 km / h kigabanukaho icya cumi cyamasegonda kandi imikoreshereze iratera imbere. Ikibazo? Guhitamo bizapima 4040 euro kuri bije isanzwe isabwa…
Kubijyanye n'umuvuduko ntarengwa, iyi ni 280 km / h (10 km / h kurenza Amarushanwa).
Chassis ihinduka kuruta moteri
Igishimishije, ntabwo moteri yahinduye byinshi muri M2 CS, hamwe namakuru makuru yabitswe kuri chassis no guhuza ubutaka.
Mu rwego rwo gufata feri, M Ifumbire mvaruganda ikoresha disiki nini kumuziga uko ari ine (birashobora no kuba karubone-ceramic).
Ku guhagarikwa, dufite ibice bya fibre karubone imbere (usibye aluminium, nayo ikoreshwa inyuma), ibihuru birakomeye kandi igihe cyose bishoboka (kandi bifite akamaro) injeniyeri zashyizeho imiyoboro ikomeye (nta reberi). Intego? Hindura uburyo bwo kuyobora ibiziga no gutuza kwerekezo.
Biracyaza mubijyanye no guhagarikwa, dufite icya mbere: kunshuro yambere M2 ifite imashini isanzwe ikoreshwa na elegitoronike (hamwe nuburyo butatu: Ihumure, Siporo na Siporo +).
Kubwibyo, guhagarikwa kwifuzwa kuba ultra rigid kumuzunguruko ntibitwara gutwara mumihanda nyabagendwa bitoroshye.
Mugihe kimwe, birashoboka guhindura uburemere bwa steering (ibyo ndetse no muburyo bwa Comfort burigihe biremereye cyane), igisubizo cyibikoresho (byikora), igisubizo cya gahunda ihamye, igisubizo nijwi rya moteri (nanone birashobora guhinduka ukoresheje buto kuri kanseri yo hagati).
Mubisanzwe hamwe na M2 Amarushanwa dufite M Active Differential, auto-blocking na M Dynamic Mode, sub-imikorere ya sisitemu yo kugenzura ituze itanga urwego runini rwo kunyerera.
Kubijyanye no kwifungisha, iyo ibonye igihombo gito cya moteri irashobora guhindura rwose itangwa ryumuriro hagati yiziga ryinyuma (100-0 / 0-100), urwego rwiza rwo guhagarika rusobanurwa hanyuma rugashyirwa kuri moteri. amashanyarazi muri milisegonda 150.
Byingirakamaro cyane muburyo butunguranye butangirira hejuru hamwe na degre zitandukanye zo gufata, iyi auto-lock ntabwo ifasha gusa gukurura imodoka mumurongo (kurwanya munsi yimbere mugihe winjiye kumurongo ufatanye wakozwe kumuvuduko mwinshi) ariko nanone uyihindura mugihe byihutirwa byigihe atubwira ko ari byiza gufata feri no guhindukira icyarimwe.
Amapine ya Michelin Pilote (245/35 imbere na 265/35 inyuma, kuri 19 "ibiziga byumukara usanzwe wirabura cyangwa zahabu ituje nkuburyo bwo guhitamo) nibyo bibereye cyane kubatekereza kumarana igihe kinini na CS ku murongo.
Niba igitekerezo ari ukugira ngo udukino twinshi cyane twimikino ngororamubiri kubantu bamwe bagenda gahoro gahoro kumuhanda (wenda usanzwe utekereza gushimira kumodoka ifite ibintu byose kugirango ibe icyegeranyo), noneho Super ikwiye cyane Amapine ya siporo (vuga gusa, kubuntu, mugihe utumiza).
Ku murongo wo gutandukanya itandukaniro
Tumaze kwerekana ibyangombwa bya BMW M2 CS, ntakintu nakimwe nko kuyikorera kumuzunguruko (muriki gihe i Sachsenring, mubudage) kugirango ugerageze kumenya bimwe mubyasezeranijwe.
Nyuma ya byose, hamwe nuru rwego rwimikorere, uburambe inyuma yiziga kumuhanda ntibyaba nko kumurikira, kabone niyo byakwemerera gusobanukirwa imiterere iva mubikoresho bya elegitoroniki.
Gutangira buto, inkuba ya moteri, inshinge ziza mubuzima kandi ngaho genda… Ntibikwiye ko uvuga ko iyi ari imodoka yihuta, byihuse.
Muri kilometero 0 kugeza 100 km / h ndetse ikubita mukeba wayo nyamukuru "hanze yumuryango", ihenze cyane (igura amayero 138,452) ariko itabogamye kandi iringaniye mubitekerezo (tuyikesha moteri ya moteri yo hagati) Porsche Cayman GT4.
Itandukaniro riri hafi igice cyamasegonda, hanyuma Cayman hamwe na bokisi bayo baterana silindiri itandatu, 4.0 l, ikirere cya 420 hp kumuvuduko wo hejuru ugera kuri 304 km / h ugereranije na 280 km / h ya M2 CS.
Ibi ahanini biterwa na aerodinamike yarushijeho kunonosorwa hamwe nuburemere buke (hafi kg 130 munsi), amaherezo ikayemerera kwirata cyane uburemere / imbaraga zingana (3.47 kg / hp kuri Porsche na 3.61 kuri BMW) bityo bikishyura kububasha bwo hasi no kubura kwa turbo.
Chassis nziza
Urebye impinduka nyinshi muri chassis no guhuza ubutaka hamwe nimiterere yabyo, ntibitangaje ko, nubwo haba hafi y "ivugurura", M2 CS ishobora kwirata chassis nziza.
Mubyukuri, niyo imwe mumodoka ya BMW ikora neza kumurongo, ntakintu gito urebye igipimo kinini cyibiranga Bavarian muriki kibazo.
Ku mihanda yumye, twavuga ko imbere yimodoka yatewe hasi kandi ko arinyuma ikuraho inzira, hamwe ningendo nini cyangwa ntoya, bitewe nuburyo bwo kugenzura umutekano bwatoranijwe.
Ariko, niba gufata ari byiza cyangwa niba asfalt itose, inyuma ya M2 CS ikunda gushaka ubushake bwayo, kandi ntabwo buri gihe iyo bigeze kuri ibyo.
Muri ibi bihe, bizaba byiza gukora laps yumurongo "ukoresheje ukuboko kumwe munsi", nukuvuga, hamwe no kugenzura umutekano muri gahunda idahinduka.
Kubijyanye na moteri, gutinda kwa turbo ni bito cyane kandi kuba itanga umuriro wose kuri plateau kuva 2350 kugeza 5500 rpm ningirakamaro kugirango silinderi ihore "yuzuye", cyane cyane muri moteri ya turbo.
Nubwo fibre nyinshi ya karubone, kuzigama ibiro ugereranije na M2 irushanwa ni kg 40 gusa.
Mu gice cyo kohereza, hamwe na garebox yintoki hariho imbaraga nyinshi (kandi "abigizemo uruhare" abapriste bazavuga).
Hamwe nimikorere ibiri-ihuza ibice birindwi, haribintu byinshi byibanda kuri trayektori mugihe ibyuma biguruka hejuru kugeza hasi hamwe na padi inyuma yimodoka kandi urashobora kuzigama amasegonda make kuri lap.
Ahantu hahanamye, uburemere buringaniye hejuru yimitambiko ibiri hamwe no gukomera kwinshi kwa chassis / imikorere yumubiri bituma BMW M2 CS itembera kumurongo uhindukirira hamwe numusifuzi wemewe.
Ibi ni nubwo muburyo bumwe bwihuse bwo kwagura inzira bigenda bigaragara, abajenjeri b'Abadage bavuga ko babigambiriye kuko bifasha kumva aho imipaka igeze.
Izi mipaka nazo ziri kure cyane kubera guhuza n'imihindagurikire y'ikirere mu kugenzura umuzingo w'umubiri no mu guhagarikwa gukomeye niba duhisemo uburyo bwa Sport +.
Ariko, muricyo gihe, birashobora kuba byiza guhitamo progaramu iringaniye yo kuyobora, ikumva iremereye - yamara neza, bitewe nubwiyongere buke bwa camber.
Nkaho hari M Mode ebyiri za buto kuri ruline, urashobora gushiraho igenamiterere ryawe kuri
gearbox / moteri / kuyobora / guhagarika / gukurura kugenzura hanyuma ushake uwo ukunda byiza.
Icyifuzo ni ukugira kimwe hamwe nicyifuzo cyatoranijwe kumuhanda ikindi kumurongo, bityo ukabika umwanya.
Bizagera ryari kandi bizatwara angahe?
Hamwe numubare wubatswe uracyari ikibazo gifunguye, ibintu bibiri bimaze gushidikanywaho kuri BMW M2 CS.Iya mbere ni uko igera ku isoko muri uku kwezi naho iya kabiri ni uko verisiyo yohereza intoki igura amayero 116 500 naho variant hamwe no kohereza mu buryo bwikora igera kuri 120 504.
