Amaculo okugcina omsebenzi womculo ophumelelayo kufanele abe okhethekile. Futhi njenganoma yimuphi umqambi odumile, i-BMW ikwazi kahle lokhu ngoba kukhona okufanayo ezimotweni, okungesinye sezizathu zokuvela kwezimoto. BMW M2 CS.
Uma ukukhiqizwa kwemodeli kugcina kunenguqulo emaphakathi, leyo yinto enamathela enkumbulweni eqoqiwe njengezinambuzane kuwindshield ekupheleni kohambo lweholide lasehlobo.
Ngakho i-BMW M2 CS iphawula ukuphela kwe-2 Series (ungakapheli unyaka kuza isizukulwane esisha). Uma ukhumbula, lokhu manje kunengxenye enkulu yohlu olunikezwa isiteji sakamuva sokushayela ngamasondo angaphambili, noma kunjalo, kulo msebenzi womzimba uhlale uthembekile ezimisweni zomkhiqizo waseBavaria, okumele kube khona izimoto zezemidlalo ezinokuziphatha okulinganiselwe. iphushwa ngamasondo angemuva futhi ayidonswa ngamasondo angaphambili.
imodeli engakaze ibonwe
Ngisho uma kubhekwa ukuthi kunomncintiswano we-M2 (esebenzisa injini efanayo, kodwa engaphansi ngo-40 hp kodwa efanayo ne-550 Nm), onjiniyela baseJalimane bafuna ukulinyusa izinga kakhulu.
Bhalisela iphephandaba lethu
Ngakho-ke, njengoba uMarkus Schroeder, umqondisi wale phrojekthi esichazela, kungokokuqala ngqa ukuthi kuzalwe uchungechunge olulinganiselwe lwemodeli ye-sporty compact BMW (ekuqaleni kwakukhulunywa ngamayunithi angama-75 kuphela kodwa kungenzeka ukuthi idlulele. lokho, kuya ngokuthi ifuna ukusabela kanjani manje lapho yethulwa).
Ngokuka-Schroeder, "i-M2 CS iphinde iphakamise imvilophu eguquguqukayo ehlongozwe uMqhudelwano we-M2 ukuze ijabulise uhlobo lwekhasimende oluyivelakancane kodwa olufuna kakhulu elithanda ukungena ngezikhathi ezithile emzileni".
Ngamanye amazwi, esimweni esicacile kakhulu, lapho ukuqedwa kweshumi lesibili nge-lap ngayinye kuseshwa ngokungaphezi njengokungathi iGrail Engcwele, ngakho-ke kunengqondo ukuthi umqhubi ovamile, ongashiyi ama-asphalt omphakathi, ngeke abe. ukwazi ukubona kuyaziswa. .
"Engikufuna ngakho" i-carbon fiber
Khona-ke, i-CS yokuqala ye-M2 (kwakukhona ama-CS ku-M3 ne-M4) futhi isebenza njengesisekelo semoto yomjaho i-BMW, into okunzima ukuyikholelwa ngedrama eqinisiwe yemigqa nezingxenye.
Ake siqale ngomsebenzi womzimba wale BMW M2 CS: udebe olungezansi lukabhampa wangaphambili, ibhonethi (enesisindo esiwuhhafu njengoMncintiswano futhi ihlanganisa nokushaywa umoya omusha) kanye nephrofayili ye-aerodynamic (Gurney) ekhuphuka phezu kwesivalo se ipotimende lisha.
I-carbon fiber ikhona yonke indawo.
Njenge-diffuser engezansi kwebhampa yangemuva, zonke lezi zakhi zenziwe nge-carbon fiber, futhi kuzo zonke izimo, into ekhanyayo kakhulu neqinile kakhulu ivezwa ngezinga elikhulu noma elincane.
Inhloso yalezi zinto ukunyusa ingcindezi ye-aerodynamic kanye nomoya wesiteshi nxazonke nangaphansi kwemoto, kuncishiswe ukudumazeka.
Ukusetshenziswa kwe-carbon fiber kwakungenxa yesifiso sokunciphisa isisindo. Kuyathakazelisa ukuthi i-M2 CS inesisindo esingaphansi kancane kunoMqhudelwano (“ngaphansi kuka-40 kg”, ngokusho kukaSchroeder) ngesamba esingu-1550 kg.
Inani elikhulu, hhayi okungenani ngenxa yokuthi ukumiswa okuguquguqukayo kwengeza isisindo uma kuqhathaniswa “nokungenzi lutho” komfowethu wobubanzi. Konke kungenxa yokuthi abakwaBMW bakhethe ukungenzi imoto eyeqisayo.
Ukube lokho bekuyinhloso eyinhloko, bekuyoba lula ukwenza ngaphandle komugqa wezihlalo zangemuva, isiphephetha-moya noma isistimu yomsindo. Ngakho-ke, ukwanda kwezingxenye ze-carbon fibre kanye nokwehliswa kwe-acoustic insulation material ye-cabin akwanele "ukudla" okuqinile.
Injini yokufanisa
Inamasilinda asemgqeni ayisithupha, 3.0 l kanye (lapha) 450 hp, le njini ihlome ngobunjiniyela obungcono kakhulu be-BMW: ukusuka kuma-mono-scroll turbos amabili, ukuya kumjovo oqondile oqondile, kuya ohlelweni lwe-valve actuation (Valvetronic ) noma i-Vanos crankshaft (i-inlet ne-exhaust), akukho lutho olushodayo.
Noma kunjalo, ukwehliswa kwesisindo okunamahloni kusho ukuthi i-BMW M2 CS ayenzi kangcono kakhulu kunomncintiswano we-M2 onamandla kancane ngokusebenza.
Sesikushilo lokho, ngo-gearbox onamagiya ayisithupha ashintshwayo (owokuqala kwiBMW enegama le-CS) ijubane lika-100 km/h lifika ku-4.2 s, ngamanye amazwi, irekhodi elifanayo neleCompetition ene-automatic transmission ene dual clutch M DCT. .
Uma ihlome ngalo gearbox, iBMW M2 CS ibona isikhathi sisuka ku-0 siye ku-100 km/h sehla ngo-2 weshumi wesekhondi futhi ukusetshenziswa kwayo kuyathuthuka. Inkinga? Ukuyikhetha kuzoba nesisindo esingama-euro angama-4040 kwisabelomali esivele sifuna…
Mayelana nesivinini esiphezulu, lesi ngu-280 km/h (10 km/h ngaphezu koMqhudelwano).
I-chassis ishintsha kakhulu kunenjini
Kuyathakazelisa ukuthi kwakungeyona injini eshintshe kakhulu ku-M2 CS, izindaba ezinkulu zigcinelwe u-chassis kanye nokuxhunywa komhlaba.
Emkhakheni wokubhuleka, amabhuleki e-M Compound asebenzisa amadiski amakhulu kuwo wonke amasondo amane (angaba ngisho ne-carbon-ceramic).
Ekumisweni, sinezingxenye ze-carbon fiber ngaphambili (ngaphezu kwe-aluminium, ebuye isetshenziswe ngemuva), ama-bushings aqinile futhi noma nini lapho kungenzeka (futhi okuzuzisayo) onjiniyela baye bafaka uxhumano oluqinile (ayikho irabha). Umgomo? Lungiselela ukuqondiswa kwamasondo nokuzinza kokuqondisa.
Sisesemkhakheni wokumiswa, sineyokuqala: okokuqala i-M2 ine-adaptive electronic shock absorbers (enezindlela ezintathu: Comfort, Sport and Sport+).
Ngakho-ke, ukumiswa okufiswa ukuthi kuqine kakhulu kusekethe akukwenzi ukushayela emigwaqweni yomphakathi kube inkinga yokungakhululeki.
Ngesikhathi esifanayo kungenzeka ukushintsha isisindo sokuqondisa (okuyinto ngisho nemodi ye-Comfort ihlale inzima kakhulu), impendulo yegiya (okuzenzakalelayo), impendulo yohlelo lokuzinza, impendulo kanye nomsindo wenjini. (futhi ingashintshwa ngenkinobho ku-centre console).
Ngokufana nokuncintisana kwe-M2 sine-M Active Differential, i-auto-blocking kanye ne-M Dynamic Mode, umsebenzi ongaphansi wesistimu yokulawula ukuzinza evumela izinga elikhulu lokushelela.
Ngokuqondene nokuzivimbela, lapho ibona ukulahlekelwa okuncane kokunyakaza kungashintsha ngokuphelele ukulethwa kwe-torque phakathi kwamasondo amabili angemuva (100-0 / 0-100), izinga elifanele lokuvinjelwa libe selichazwa futhi lisetshenziswe injini. ugesi ngama-millisecond angu-150.
Iwusizo kakhulu uma iqala ngokuzuma ezindaweni ezinamadigri ahlukene okubambelela, le-auto-lock ayisizi nje kuphela ukudonsa imoto iye ejikeni (i-cobating understeer uma ingena kumajika aqine kakhulu enziwe ngesivinini esikhulu) kodwa futhi iyayisimamisa uma ukuphuthuma okwamanje. isitshela ukuthi kungcono ukubhuleka nokujika ngesikhathi esifanayo.
Amathayi e-Michelin Pilot Cup (245/35 ngaphambili nangu-265/35 ngemuva, ngamasondo angu-19” enziwe ngegolide elimnyama noma elifiphele njengenketho) afaneleka kakhulu kulabo abacabanga ukuchitha isikhathi sabo esiningi ne-CS. endleleni.
Uma umbono uwukuba ne-compact super sports compact emangalisa kakhulu kwabanye ukugibela ngezinyawo ezihamba kancane emgwaqeni (mhlawumbe kakade ucabanga ngokwazisa okuzayo kwemoto enakho konke engakwazi ukuba yiqoqo), khona-ke i-Super efaneleka kakhulu. Amathayi ezemidlalo (vele ucacise, mahhala, uma uyala).
Isendleleni yokumaka umehluko
Ngemva kokwenza izethulo ezidingekayo ze-BMW M2 CS, akukho okufana nokuyiqhuba kusekethe (kulokhu e-Sachsenring, eJalimane) ukuzama ukuthola ezinye zezinzuzo ezithenjisiwe.
Phela, ngaleli zinga lokusebenza, isipiliyoni ngemuva kwesondo emgwaqeni singaba ngaphansi kokukhanyisa, ngisho noma kukuvumela ukuba uqonde ubuntu obuvela ku-electronic shock absorbers.
Inkinobho yokuqala, ukuduma kwenjini, izinaliti ziphila futhi lapho uhamba… Akufanele ukusho ngokungananazi ukuthi lena imoto esheshayo, eshesha kakhulu.
Emjahweni ongu-0 kuye ku-100 km/h ihlula ngisho imbangi yayo enkulu “ngaphandle kweminyango”, ebiza kakhulu (ibiza ama-euro angu-138,452) kodwa ukusabela okungathathi hlangothi futhi okunokulinganisela ekuphenduleni kwayo (ngokwemvume yokulungiswa kwenjini ephakathi nendawo) I-Porsche Cayman GT4.
Umehluko ucishe ube uhhafu wesekhondi, bese kuba iCayman ne-boxer yayo engu-six-cylinder, 4.0 l, emkhathini ongu-420 hp ngesivinini esiphezulu esifinyelela ku-304 km/h uma kuqhathaniswa ne-M2 CS engu-280 km/h.
Lokhu kubangelwa kakhulu ukusebenza kwe-aerodynamics ecwenge kakhudlwana kanye nesisindo esiphansi (cishe ngo-130 kg ngaphansi), okugcina kuyivumela ukuba iziqhenye ngesilinganiso esivumayo sesisindo/amandla (3.47 kg/hp ngePorsche kanye no-3.61 weBMW) futhi ngaleyo ndlela kunxeshezelwe. ngenxa yamandla aphansi kanye nokungabikho kwe-turbo.
I-chassis ekhazimulayo
Uma kucatshangelwa izinguquko eziningi ku-chassis kanye nokuxhumana komhlabathi kanye nezimfanelo zabo zangaphakathi, akumangazi ukuthi, ngisho nasekupheleni "kwezinguquko", i-M2 CS ingaziqhayisa nge-chassis ekhazimulayo.
Eqinisweni, ingenye yama-BMW asebenza kahle kakhulu emzileni, okungeyona into encane uma kubhekwa igeji ephezulu yohlobo lwaseBavaria kulokhu.
Emigwaqweni eyomile bekungashiwo ukuthi ingaphambili lemoto litshalwe phansi futhi ingemuva elishanela ithrekhi, linyakaze kakhulu noma lincane, kuye ngokuthi indlela yokulawula ukuzinza ekhethiwe.
Kodwa, uma ukubamba kungalungile noma uma itiyela limanzi, ingemuva le-M2 CS livame ukufuna ukuzuza intando yalo, futhi hhayi njalo uma kuziwa kulokho.
Kulezi zimo, kuzoba ngcono ukwenza ama-laps ethrekhi "ngesandla esisodwa ngaphansi", okusho ukuthi, ngokulawula ukuzinza ohlelweni olungenakuguqulwa kakhulu.
Mayelana nokusebenza kwenjini, ukubambezeleka kokuphendula kwe-turbo kuncane kakhulu futhi iqiniso lokuthi iletha yonke i-torque endaweni eyithafa ukusuka ku-2350 kuya ku-5500 rpm kubalulekile ukuze amasilinda ahlale “egcwele”, ikakhulukazi enjinini ye-turbo.
Naphezu kwe-carbon fiber eningi, ukonga isisindo uma kuqhathaniswa noMqhudelwano we-M2 kungu-40 kg kuphela.
Esahlukweni sika-gearbox oshintshwayo kukhona abantu abaningi abasebenzayo (futhi bazosho "ukubandakanyeka" okungaphezulu).
Nge-automatic dual-clutch seven ratios, kukhona ukugxila okwengeziwe kuma-trajectories kuyilapho amagiya endizela esuka phezulu aye phansi namapaddle ngemuva kwesiteringi futhi ungakwazi ukonga imizuzwana embalwa emlenzeni ngamunye.
Emithambekeni, ukusatshalaliswa kwesisindo esilinganayo phezu kwama-ekseli amabili kanye nokuqina okukhuphukile kwe-chassis/umsebenzi womzimba kwenza i-BMW M2 CS igeleze isuka ekujikeni iye ekujikeni nesiqiniseko somshicileli oqinisekisiwe.
Lokhu kwenzeka nakuba kwamanye amajika asheshayo kubonakala ukuthambekela kokwandisa umzila, onjiniyela baseJalimane abathi kuyinhloso ngoba kusiza ukuqonda ukuthi imingcele ikuphi.
Le mikhawulo nayo ikude ngenxa yokumiswa kwe-adaptive ekulawuleni i-body roll kanye nokuqina kwe-suspension uma sikhetha i-Sport+ mode.
Kodwa-ke, kuleso simo kungase kube ukuhlakanipha ukukhetha uhlelo olulingene kakhulu lwesiteringi, oluzwakala lusinda kakhulu - kodwa lunembile impela, ngenxa yokwenyuka kancane kwe-wheel camber.
Njengoba kunamabhathini amabili e-M Mode esiteringini, ungakwazi ukuhlela amasethingi owathandayo
u-gearbox/injini/isiteringi/ukumiswa/ukulawula ukuhamba futhi uthole oyithanda kakhulu.
Okuhle kakhulu ukuba neyodwa enezilungiselelo ezithandwayo zomgwaqo futhi enye ibe yethrekhi, ngaleyo ndlela wonge isikhathi.
Ifika nini futhi izobiza malini?
Njengoba isibalo samayunithi azokwakhiwa kusewumbuzo ovulekile, zimbili izinto eseziqinisekile ngeBMW M2 CS.Eyokuqala ukuthi ifika emakethe kule nyanga kanti okwesibili ukuthi inguqulo nge-manual transmission ibiza ama-euro angu-116 500 futhi okuhlukile okunokudluliselwa okuzenzakalelayo kufinyelela ku-120 504 euros.
