Iichodi zokugqibela zomsebenzi womculo oyimpumelelo kufuneka zibe zizodwa. Kwaye njengaye nawuphi na umqambi odumileyo, iBMW iyazi kakuhle le nto kuba into efana nale ibambe iimoto, sesinye sezizathu zokuvela kwemoto. BMW M2 CS.
Ukuba imveliso imodeli iphela ngoguqulelo mediocre, loo nto iba njengoko incamathele kwinkumbulo edibeneyo njengezinambuzane kwi windshield ekupheleni kohambo lweholide yasehlotyeni.
I-BMW M2 CS ngoko iphawula ukuphela kwe-2 Series (kwisithuba sonyaka kufika isizukulwana esitsha). Ukuba uyakhumbula, oku ngoku kunenxalenye enkulu yoluhlu olusetyenziswa yiqonga langaphambili levili lokuqhuba, nangona kunjalo, kulo msebenzi womzimba uye wahlala ethembekile kwimigaqo ye-brand yaseBavaria, apho iimoto zemidlalo ezinokuziphatha okusemgangathweni kufuneka zibe. etyhalwa ngamavili angasemva kwaye engatsalwanga ngamavili angaphambili.
imodeli engazange ibonwe ngaphambili
Nokuba kujongwe ukuba kukho uKhuphiswano lwe-M2 (olusebenzisa i-injini enye, kodwa nge-40 hp ngaphantsi kodwa i-550 Nm efanayo), iinjineli zaseJamani zafuna ukunyusa umgangatho nangakumbi.
Bhalisa kwincwadana yethu
Ke, njengoko uMarkus Schroeder, umlawuli wale projekthi esicacisela, esi sisihlandlo sokuqala ukuba kuzalwe uthotho olulinganiselweyo lwemodeli ye-BMW ye-sporty compact (ekuqaleni kwakuthethwa ngeeyunithi ezingama-75 kuphela kodwa kunokwenzeka ukuba iya kudlulela ngaphaya. oko, kuxhomekeke kwindlela ifuna ukusabela ngayo ngoku ekusungulweni kwayo).
Ngokuka-Schroeder, "i-M2 CS iphakamisa ngakumbi imvulophu eguquguqukayo ecetywayo luKhuphiswano lwe-M2 ukukholisa uhlobo olunqabileyo kakhulu kodwa olunzima kakhulu lomthengi othanda ukwenza amaxesha ngamaxesha kumzila".
Ngamanye amazwi, kumxholo othe ngqo, apho ukupheliswa kweshumi lesibini kwi-lap nganye kukhangelwa ngokuqhubekayo ngokungathi yiGrail eNgcwele, kwaye ngoko ke ingqiqo yokuba umqhubi oqhelekileyo, ongashiyi i-asphalt yoluntu, akayi kuba nzima. okwaziyo ukubona kuxatyisiwe.
"Yintoni endifuna yona" i-carbon fiber
Ngoko ke, i-CS yokuqala ye-M2 (kwakukho i-CS kwi-M3 kunye ne-M4) kwaye isebenza njengesiseko semoto yomjaho we-BMW, into enzima ukuyikholelwa ngedrama eqinisiweyo yemigca kunye namacandelo.
Masiqale ngomsebenzi womzimba wale BMW M2 CS: umlebe ongezantsi webumper yangaphambili, ibhonethi (enobunzima besiqingatha soKhuphiswano kwaye ibandakanya ukungena komoya omtsha) kunye neprofayile ye-aerodynamic (Gurney) enyuka ngaphezulu kwesiciko. isuitcase intsha.
Ikhabhon fiber ikuyo yonke indawo.
Njenge-diffuser engaphantsi kwe-bumper yangasemva, zonke ezi zinto zenziwe nge-carbon fiber, kwaye kuzo zonke iimeko, i-ultra-light kunye ne-ultra-rigid material ibonakaliswe kwinqanaba elikhulu okanye elincinci.
Injongo yezi zinto kukunyusa uxinzelelo lwe-aerodynamic kunye nomoya wejelo ngeenxa zonke naphantsi kwemoto, ukunciphisa isiphithiphithi.
Ukusetyenziswa kwe-carbon fiber kwakungenxa yomnqweno wokunciphisa ubunzima. Kuyathakazelisa ukuba i-M2 CS inobunzima obungaphantsi koKhuphiswano ("ngaphantsi kwe-40 kg", ngokutsho kukaSchroeder) kwi-1550 kg.
Ixabiso elikhulu, hayi ngenxa yokuba ukunqunyanyiswa okuguquguqukayo kongeza ubunzima xa kuthelekiswa ne "passive" yoluhlu lomzalwana. Konke ngenxa yokuba uBMW wakhetha ukungenzi imoto egqithise kakhulu.
Ukuba oko bekuyeyona njongo iphambili, bekuya kuba lula ukwenza ngaphandle koluhlu lwezihlalo ezingasemva, umoya opholileyo okanye inkqubo yomsindo. Ke, ukonyuka kweendawo zekhabhoni zefiber kunye nokwehliswa kwezinto zokugquma i-acoustic ye-cabin akwanelanga "ukutya" okungqongqo ngakumbi.
Injini yokudibanisa
Ngeesilinda emithandathu engaphakathi, 3.0 l kunye (apha) 450 hp, le njini ixhotyiswe ngeyona ndlela ingcono yobunjineli beBMW: ukusuka kwii-turbos ezimbini ze-mono-scroll, ukuya kwisitofu esichanekileyo esichanekileyo, ukuya kwi-valve actuation system (Valvetronic). ) okanye iVanos crankshaft (i-inlet kunye ne-exhaust), akukho nto ilahlekileyo.
Kusenjalo, ukucutha ubunzima buneentloni kuthetha ukuba iBMW M2 CS ayenzi ngcono kunoKhuphiswano olunamandla kancinane lweM2 ngokwemigaqo yokusebenza.
Oko kuthetha, nge-6-speed manual gearbox (eyokuqala kwi-BMW enegama lesiteketiso le-CS) i-100 km / h ifika kwi-4.2 s, ngamanye amazwi, irekhodi elifanayo noKhuphiswano oluzenzekelayo olusebenzisa i-double clutch M DCT. .
Xa ixhotyiswe ngale gearbox, iBMW M2 CS ibona ixesha ukusuka kwi-0 ukuya kwi-100 km/h lehla nge-2 yeshumi yesekhondi kwaye ukusetyenziswa kuyaphucuka. Ingxaki? Ukuyikhetha kuya kuba nobunzima be-euro ezingama-4040 kuhlahlo lwabiwo-mali olusele lufuna…
Ngokubhekiselele kwisantya esiphezulu, le yi-280 km/h (10 km/h ngaphezu koKhuphiswano).
I-chassis itshintsha ngaphezu kwe-injini
Okubangel 'umdla kukuba, yayingeyiyo injini eyatshintsha kakhulu kwi-M2 CS, iindaba ezinkulu zigcinelwe i-chassis kunye nokudibanisa komhlaba.
Kumhlaba wokuqhobosha, iibhuleki zeM Compound zisebenzisa iidiski ezinkulu kuwo omane amavili (zinokuba yikhabhoni-ceramic).
Kwi-suspension, sinamalungu e-carbon fiber ngaphambili (ukongeza kwi-aluminium, ekwasetyenziswa ngasemva), i-bushings iqinile kwaye xa kunokwenzeka (kunye nenzuzo) iinjineli ziye zasebenzisa uxhulumaniso oluqinileyo (akukho rubber). Inqaku? Lungiselela isikhokelo sevili kunye nokuzinza komkhombandlela.
Kusenjalo kwintsimi yokunqunyanyiswa, sineyokuqala: okokuqala i-M2 ine-absorber esemgangathweni ye-electronic adaptive (kunye neendlela ezintathu: Induduzo, iMidlalo kunye neMidlalo +).
Ke ngoko, ukunqunyanyiswa okunqwenelwa ukuba kube ngqongqo kakhulu kwisekethe akukwenzi ukuqhuba kwiindlela zikawonke-wonke kube yingxaki yokungakhululeki.
Kwangaxeshanye kunokwenzeka ukuba ukwahluka kobunzima bokuqhuba (okuthi nakwimowudi yeComfort isoloko inzima kakhulu), impendulo yegiya (automatic), impendulo yenkqubo yokuzinza, impendulo kunye nesandi senjini. (ikwanokutshintsheka ngeqhosha elikwicentre console).
Ngokufana noKhuphiswano lwe-M2 sinoMhluko osebenzayo we-M, i-auto-blocking kunye ne-M Dynamic Mode, i-sub-function yenkqubo yokulawula uzinzo evumela ukuba i-degree enkulu ye-slippage.
Ngokubhekiselele kwi-self-blocking, xa ibona ilahleko encinci ye-motivity inokutshintsha ngokupheleleyo ukuhanjiswa kwe-torque phakathi kwamavili amabini angasemva (100-0 / 0-100), iqondo elifanelekileyo lokuthintela liyachazwa kwaye lisetyenziswe yi-injini. umbane kwi-150 milliseconds.
Iluncedo kakhulu kwisiqalo esinesiquphe esinemigangatho eyohlukeneyo yokubamba, oku kutshixa okuzenzekelayo akuncedi nje ukutsalela imoto kwigophe (i-cobating understeer xa ingena kwezona gophe zixineneyo ezenziwe ngesantya esiphezulu) kodwa ikwayizinzisa xa ungxamiseko lwalo mzuzu. isixelela ukuba kungcono ukuqhobosha nokujika ngaxeshanye.
Amavili e-Michelin Pilot Cup (i-245/35 ngaphambili kunye ne-265/35 ngasemva, kwi-19" yamavili amnyama amnyama okanye igolide ebuthuntu njengokhetho) ngawona afanelekileyo kwabo bacinga ukuchitha ixesha labo elininzi kunye ne-CS. endleni.
Ukuba umbono kukuba nje ube nomdlalo obalaseleyo wezemidlalo omangalisayo wokukhwela abanye ngesantya esicothayo endleleni (mhlawumbi sele ucinga malunga noxabiso lwexesha elizayo lwemoto enayo yonke into enokuthi ibe yingqokelela), ke eyona ifanelekileyo iSuper Amavili ezemidlalo (chaza nje, ngaphandle kwentlawulo, xa u-odola).
Kwindlela yokumakisha iyantlukwano
Emva kokwenza iinkcazo-ntetho eziyimfuneko ze-BMW M2 CS, akukho nto ifana nokuyiqhuba kwisekethe (kule meko yaseSachsenring, eJamani) ukuzama ukufumana ezinye zeenzuzo ezithenjisiweyo.
Emva kwakho konke, ngeli nqanaba lokusebenza, amava emva kwevili endleleni aya kuba ngaphantsi kokukhanyisa, nokuba kukuvumela ukuba uqonde ubuntu obuvela kwi-electronic shock absorbers.
Iqhosha lokuqala, ukuduma kwe-injini, iinaliti ezibuyela ebomini kwaye apho uya khona… Akufanelekanga ukuthetha ngokugqithisileyo ukuba le yimoto ekhawulezayo, ekhawuleza kakhulu.
Kumgama osuka kwi-0 ukuya kwi-100 km/h ide yoyise imbangi yayo enkulu “ngaphandle kweminyango”, ibiza kakhulu (ixabisa i-138,452 yee-euro) kodwa ingathathi hlangothi kwaye ilungelelene kwiimpendulo (ngenceba yokwakheka kwenjini yangasemva) IPorsche Cayman GT4.
Umahluko ujikeleze isiqingatha sesibini, kwaye ke i-Cayman kunye nebhokisi yayo ye-six-cylinder, i-4.0 l, i-atmospheric 420 hp kwisantya esiphezulu esifikelela kwi-304 km / h xa kuthelekiswa ne-280 km / h ye-M2 CS.
Oku kubangelwa ubukhulu becala kwi-aerodynamics yayo esulungekisiweyo kunye nobunzima obuphantsi (malunga ne-130 kg ngaphantsi), ekugqibeleni ivumela ukuba iziqhayise ngobunzima obulungileyo / umlinganiselo wamandla (3.47 kg/hp yePorsche kunye ne-3.61 ye-BMW) kwaye ngaloo ndlela ihlawule ngenxa yamandla asezantsi kunye nokungabikho kwe-turbo.
I-chassis eqaqambileyo
Ukuqwalasela utshintsho oluninzi kwi-chassis kunye nokudibanisa komhlaba kunye neempawu zabo zangaphakathi, akumangalisi ukuba, nangona kwinqanaba "lokuguqulwa", i-M2 CS inokuqhayisa nge-chassis eqaqambileyo.
Ngapha koko, iyenye yee-BMWs ezisebenza kakuhle emgceni, engeyonto incinci xa kuqwalaselwa igeyiji ephezulu yophawu lwaseBavaria kulo mba.
Kwiindlela ezomileyo, kuya kuthiwa i-front of the car ityalwe phantsi kwaye yinto yangasemva etshayela umzila, kunye noluhlu olukhulu okanye oluncinci lokuhamba, kuxhomekeke kwindlela yokulawula ukuzinza ekhethiweyo.
Kodwa, ukuba ukubamba kuncinci okanye ukuba i-asphalt imanzi, umva we-M2 CS uvame ukufuna ukuzuza ukuthanda kwayo, kwaye akusoloko xa kuziwa kuloo nto.
Kule meko, kuya kukhethwa ukwenza i-laps yomzila "ngesandla esinye phantsi", oko kukuthi, kunye nokulawula ukuzinza kwiprogram engenakulinganiswa.
Ngokuphathelele ukusebenza kwe-injini, ukulibaziseka kwe-turbo kuncinci kakhulu kwaye into yokuba ihambisa yonke i-torque kwi-plateau ukusuka kwi-2350 ukuya kwi-5500 rpm ibalulekile ukuba iisilinda zihlale "zigcwele", ngakumbi kwi-injini ye-turbo.
Nangona i-carbon fiber eninzi, ukugcinwa kobunzima xa kuthelekiswa noKhuphiswano lwe-M2 luyi-40 kg kuphela.
Kwisahluko sothumelo, nge-gearbox ye-manual kukho amandla angaphezulu (kwaye ngakumbi "ukubandakanyeka" kwee-purists kuya kuthetha).
Ngolungelelwaniso oluzenzekelayo lwe-dual-clutch ezisixhenxe, kukho ugxininiso olungakumbi kwiitrajethi ngelixa iigiya zibhabha ukusuka phezulu ukuya ezantsi kunye namaphini okubheqa emva kwevili lokuqhuba kwaye ungagcina imizuzwana embalwa kwi-lap nganye.
Kwimithambeka, ukusabalalisa ubunzima obulinganayo phezu kwee-axles ezimbini kunye nokunyuka kokuqina kwe-chassis / bodywork kwenza i-BMW M2 CS ihambe ukusuka ekujikeni ukuya ekujikeni kunye nokuqiniseka kwe-skier eqinisekisiweyo.
Oku kunjalo nangona kwezinye iigophe ezikhawulezayo ukuthambekela kokwandisa i-trajectory kubonwa, nto leyo iinjineli zaseJamani zithi zenziwe ngabom kuba kunceda ukuqonda ukuba iphi imida.
Le mida nayo ikude ngenxa yokunqunyanyiswa okuguquguqukayo kulawulo lomqulu womzimba kunye nokuqina kokumiswa ukuba sikhetha imo yeMidlalo +.
Nangona kunjalo, kuloo meko kunokucetyiswa ukuba ukhethe inkqubo ephakathi kakhulu yokuqhuba, eziva inzima kakhulu-kodwa ichanekile, ngenxa yokonyuka okuncinci kwe-wheel camber.
Njengoko kukho amaqhosha amabini eNdlela yeM kwivili lokuqhuba, unokuseta izicwangciso ozikhethayo ngaphambili
gearbox/injini/ukuqhuba/ukumiswa/ulawulo lokutsala kwaye ufumane eyona uyithanda kakhulu.
Eyona nto ifanelekileyo kukuba ube nesetingi ekhethiweyo yendlela kunye nenye yengoma, ngaloo ndlela ugcina ixesha.
Ifika nini kwaye iza kubiza malini?
Ngenani leeyunithi eziza kwakhiwa kusengumbuzo ovulelekileyo, zimbini izinto esele ziqinisekile malunga neBMW M2 CS.Eyokuqala kukuba ibetha imarike kule nyanga kwaye okwesibini kukuba uguqulelo kunye transmission manual iindleko 116 500 euro kunye nokwahluka kunye isixa transmission oluzenzekelayo 120 504 euro.
