Ukuqaliswa kwazo zonke iimodeli zombane ziphindaphindeka, ziqinisa ukubambelela kuTesla, oya kufuneka akwazi ukuzinyanzela ngoku ukuba akasekho yedwa kwimarike. Njengo i4 , "i-coupe yeminyango emine", i-BMW iya kuhlasela i-brand yaseCalifornian kwintsimi yayo, kodwa kunye ne-sedans ekhuphisanayo yeempawu "zemveli" eziza kubonakala kwiimarike kwiinyanga ezizayo.
Le yi-BMW yesine yombane kunye neyona nto iqhelekileyo phakathi kwabo, nangona izinto ezihlukeneyo. Ukususela kwi-rim ehlanganiswe kabini (iimfuno zokupholisa zamacandelo ombane ombane ziphantsi kakhulu kwaye zihlengahlengiswa yi-lamellae kunye neendawo ezihlukeneyo ze-10) ukuya kwi-diffusers yangasemva (endaweni yokukhupha i-exhaust outlets) leyo, njengecala elisezantsi apho likhona. zixhonywe ngebhetri, ziphawulwe ngombala ozuba “i Blue”.
Ke ngoko, sijongene nemodeli yokuqala yombane evela kwaBMW ekufuneka ifikelele kwinqanaba eliphezulu lobuchule obuguqukayo bolu phawu, into efanayo kunye neenjini zokutsha ezigqwesileyo (kwaye ngokufuthi zineesilinda ezininzi), ivili elingasemva kunye nolonwabo lokuqhuba, iimpawu. apho abaninzi abakhuphisanayo bebanqwenela.
Ayisiyomodeli eyahlukileyo, njenge-i3, okanye isithuthi esiguqulweyo sisuka kwesele sikhona, njenge-iX3, eyaphuhliswa ngaphambili ukusuka ekuqaleni, ecaleni kwe-4 Series Gran Coupé, ecaleni kwayo ngoku eqala ukwenziwa. I-Munich (ifektri efumene utyalo-mali lwe-200 yezigidi ze-euro ukwenzela ukuba, ngokokuqala ngqa kwi-BMW, imoto ene-injini yokutsha kunye ne-100% yemoto yombane inokuveliswa kumgca wendibano efanayo).
Kwi-4.78 m ubude (7 cm ubude ngaphezu kwe-Series 3, kodwa ukuphakama okufanayo kwi-1.45 m kunye ne-wheelbase ye-2.85 m), umsebenzi wabaqulunqi kunye neenjineli ze-aerodynamic wawunzima ukukwazi ukufikelela kwi-coefficient (Cx) ye-0.24 . I-deflectors yangaphambili kunye ne-diffuser yangasemva, izikhokelo zomoya phambi kwamavili kwaye, nokuba zingabonakali, ukuhamba ngaphantsi kwemoto kunye nokukhuselwa kwegumbi le-injini kunye ne-casing yebhetri, yayinefilosofi eqhelekileyo yokulungiswa kwendlela yokudlula. umoya.
340 hp ukuya 544 hp, ngasemva okanye ezine-wheel drive
Ekuqaleni, kuya kubakho iinguqulelo ezimbini: i-i4 eDrive40 enenjini yombane yangasemva (340 hp kunye ne-430 Nm, i-rear-wheel drive, isantya esiphezulu se-190 km/h, isantya ukusuka ku-0 ukuya kwi-100 km/h kwi-5.7s kunye noluhlu lwama-590 km ) kunye ne-i4 M50 eyisiqalo sokudityaniswa kwe-propulsion yombane wonke ngonobumba ongu-M kunye ne-4-wheel drive.
Ngamanye amazwi, isebenzisa i-motor yombane kwi-axle nganye (ngaphambili kunye ne-258 hp kunye nomva kunye ne-313 hp), ekusebenzeni kwenkqubo ephezulu ye-544 hp kunye ne-795 Nm, oku sele kukho umsebenzi we-Sport Boost owenziwe ngumqhubi ( leyo "ifake" i-68 hp eyongezelelweyo kunye ne-65 Nm malunga nemizuzwana ye-10). Kolu lungelelwaniso “lunamandla” ngakumbi, iBMW i4 M50 ikwazi ukufota ukuya kutsho kwi-100 km/h nge-3.9s kwaye ifikelele ku-225 km/h yesantya esiphezulu, isingqi esifanele ukuthomalalisa kakhulu ukuze ukwazi ukuhlala kufutshane nemoto. I-510 km yokuzimela okuthenjisiweyo.
Amandla ahanjiswa ngokusasazwa kwesantya esinye ukuya kumavili angasemva kwi-i4 eDrive40 okanye ukuya kumavili amane akwi-i4 M50 kwaye kuphela kwiimeko apho iimeko zendlela zinyanzelisa ngolo hlobo (ngale ndlela ukuzimela akuphazamiseki ngokugqithisileyo) .
Kwisantya esomeleleyo esisecaleni okanye ekuphenduleni ilahleko yokutsalwa kwevili, amavili angaphambili athatha inxaxheba kuxanduva lokuqhubela phambili ukuphucula ukuphathwa kwe-i40 M50 kunye nezantya zogqithiselo lwetorque ephezulu kunye nolawulo oluchane ngakumbi kunangaphambili. ii-axes, ukongeza ekubeni akukho lahleko isebenzayo ebangelwa yimithwalo eshushu kwinkqubo yomatshini.
Kwelinye icala, ukusebenzisa i-motor kwi-axis nganye kukwanegalelo ekuveliseni umgangatho ophezulu kakhulu wokubuyisa amandla, anokufikelela kwi-195 kW kwi-i4 M50, kanti kwi-i4 eDrive40 ili-116 kW kuphela. Njengoko uDavid Ferrufino, umlawuli weprojekthi ye-i4 endicacisela (owathi ukususela kwiintsuku zakhe zobutsha eBolivia wayesoloko engumntu othanda iimoto):
UDavid Ferrufino, uMlawuli weProjekthi ye-BMW i4"(...) kwanele ukuba, ngokuqhuba ngobuchule, i-90% yokunciphisa isantya senzelwe ukuchacha kuphela kwaye ngaphandle kwemfuneko yokunyathela kwi-pedal ye-brake".
Amanqanaba okubuyisela aPredictive (usebenzisa ulwazi oluvela kwi-sensor kunye nokuhamba), ePhantsi, ePhakathi kunye nePhakamileyo, kwaye kunokwenzeka ukuba ushiye umkhethi wothumelo kwindawo "B", eyona inamandla kwaye ifanelekile ukuqhuba nge-pedal eyodwa (kuphela i-throttle ).
Ukusebenza ngakumbi
Isizukulwana sesihlanu se-eDrive propulsion technology iphawula inkqubela-phambili yobuchwepheshe ecacileyo, enamacandelo ahlangeneyo ngakumbi kunye nohlanganiso olungcono, uxinano lwamandla e-injini aphezulu (malunga nokunyuka kwama-50% xa kuthelekiswa nowama-2020 i3), ama-20% aphezulu womxhuzulane woxinzelelo lweebhetri (110 mm ukuphakama, 561). kg ngobunzima kwaye ibekwe kumgangatho wemoto phakathi kwee-asi ezimbini) kunye nokunyuka okubonakalayo kwamandla okutshaja amkelwe yinkqubo (ubuninzi be-200 kW).
Zombini ezi nguqulelo zisebenzisa ibhetri ye-Li-ion efanayo, apho iBMW inika iwaranti yomzi-mveliso yeminyaka esibhozo/160 000 km. Inomthamo we-83.9 kWh (80.7 kWh net), iqulethe iimodyuli ezine zeeseli ezingama-72 nganye kunye neemodyuli ezintathu zeeseli ezili-12 nganye, zonke ziyi-prismatic.
Impompo yobushushu ithatha unonophelo lokuzisa ibhetri kwiqondo lokushisa elifanelekileyo ngokukhawuleza, kunye nokunceda imisebenzi yokufudumeza kunye nokupholisa kwekhabhinethi.
Iintlawulo zingenziwa kwi-alternating current (AC), eyodwa (7.4 kW) kunye nesigaba sesithathu (i-11 kW, ithatha iiyure ze-8.5 ukusuka kwi-0 ukuya kwi-100% yentlawulo) okanye kwi-current ngqo (DC) ukuya kwi-200 kW ( I-10 ukuya kwi-80% intlawulo kwimizuzu engama-31).
Ukusebenza kakuhle kweenjini zombane ezintsha kufikelela kwi-93% (ngaphezulu kokuphindwe kabini oko kufezekiswa ziinjini zokutsha), okukhokelela ekusetyenzisweni okuncinci kwaye, ngoko ke, ukuzimela okwandisiweyo.
Oku kuguquka kwakunokwenzeka ngenxa yokuba ii-motor azisenazo ii-rotors ukuba zinyanzeliswe yimagnethi esisigxina (i-asynchronous okanye i-synchronous), kwaye ngoku inikwe amandla ombane (obizwa ngokuba yi-ESM okanye i-BLDC, oko kukuthi, i-brushless motor ngqo yangoku) , kunye nenzuzo ukwenza unikezelo lwamandla luxinene, ngokukhawuleza kwaye luhambelana, ngaphezu kokuphelisa ukusetyenziswa kweentsimbi ezinqabileyo (eziyimfuneko kumacandelo magnetic) ekwenzeni i-rotor.
BMW i4 M50
Imodeli ye-3 ye-Anti-Tesla
I-i4 entsha siyibone ngezihlandlo ezibini, esinye ekuqaleni kwalo nyaka sisekwindawo yomqhubi wenqwelo-moya (ngelixa imoto ibikhokelwa zizandla ezinolwazi zika “yise” we-i4) kwaye kutshanje emva kwevili le-i4 M50, rhoqo kwiziko lovavanyo lweBMW kumntla weMunich.
UFerrufino wayegxininisa ukuba "le yenye yezona moto zibalulekileyo ze-BMW kwiminyaka yakutshanje kuba inomsebenzi wokudlulisa i-DNA yayo kwixesha le-electromobility", kunye nokuthatha ithuba loku "peck" uTesla:
UDavid Ferrufino, uMlawuli weProjekthi ye-BMW i4"Kufuneka sithembeke kwisiko sokwenza iimoto ezikhuthaza abo baziqhubayo, kwaye ke, ukukhawuleza ngokukhawuleza kumgca othe ngqo kukude ekubeni yinjongo"...
Oku akuthethi ukuba, nokuba isetyenziselwa ukuba sisalathiso esisetyenziswa ngamanye ama-brand ekuphuhliseni iimodeli zabo ezintsha, i-BMW ayithathi isikhundla esitsha: "I-Tesla's Model 3 ibisoloko ikhona kule projekthi, okoko yaqalayo. ”, uvuma uFerrufin.
Akumangalisi ukuba iModeli ye-3 yenza i-100% yokuhamba kombane ifikeleleke kwaye ifunwa ngamawaka abathengi e-US, eYurophu nase-Asia. Imilinganiselo kunye nemilinganiselo yeemodeli ezimbini ziphantse zifana kwaye nangona inika indawo enhle kubantu abadala abane kunye nempahla yempahla enesisa (470-1290 l), le i4 ngokucacileyo ayifanelekanga kumntu wesihlanu, oya kuhlala ehamba eqinile kakhulu. kwaye ungakhululekanga phakathi kwemoto.umqolo wesibini wezihlalo.
Unamandla "kwi-BMW"
Ukususela apha ukuya phambili, iiyantlukwano ziqala ukuphawulwa, ngokukodwa ngokubhekiselele kwi-dynamics, kuyo yonke into ehamba ngaphaya kwe-ballistic iqala ukuba nayiphi na i-Tesla esele isijwayele kwaye i-BMW iya kubonelela ngeemoto zayo zombane.
Into eyayibonakala kumthamo wokuqhawuka ochukumisayo phambi kwegophe ngalinye, ukukwazi ukugcina i-trajectory kunye nokukhawuleza ngokupheleleyo ngaphambi kokuba ubuyele ngokuthe ngqo, uhlala unozinzo oluninzi kwiintshukumo zomzimba.
Singaphakathi kwemodeli engenamandla kangako — i4 eDrive40 — enevili elingasemva, kodwa inemithombo yomoya kwi-asi engasemva (esemgangathweni kuzo zonke iinguqulelo), ngelixa iidampers eziguquguqukayo zombane (ezilawula ivili ngalinye ngokwahlukeneyo) ziya kuba yinxalenye ye-eDrive40’s ozikhethelayo. izixhobo kunye nomgangatho kwi-M50.
Inxalenye yokufaneleka kwendlela evakalelwa ukuba ibhalansi inento yokwenza netekhnoloji yokudambisa itekhnoloji yokunciphisa iintshukumo ezizikayo zomzimba ngexesha lokukhawulezisa, njengoko yenzayo inkqubo yokunciphisa ukutyibilika kwevili (ARB, yaqalwa kwi-i3, kodwa apha okokuqala ngentsebenziswano i-All-wheel drive) inegalelo ekuphuculeni ukutsala kunye nokuzinza kwicala eliya ngakulo, nakwindawo ezimtyibilizi.
Oku kwenza ukuba isiqalo ngasinye siqalise ngephanyazo kwaye ngaphandle kokuthandabuza, into eye yacaca ngakumbi xa ndithatha ivili lokuqhuba le-BMW i4 M50. Apha kukho izicwangciso ezithile zemithombo, i-dampers kunye ne-stabilizer bars (konke okungqongqo), ikhonkco elongezelelweyo phakathi kweenqaba zokumisa ngaphambili, i-sport steering (kunye nezicwangciso ezibini, enye ethe ngqo kwaye enye ikhululekile) kunye ne-M Sport brakes.
Enye yeendawo apho uqhubela khona i-BMW i4 eyona nto imangaliswe kakhulu kukunyathela isiqhoboshi, ukuqhubela phambili kwaye kunamandla kunayo nayiphi na imoto yombane endiyihambileyo. UFerrufini uyancuma, phambi kokuba achaze ukuba kutheni: "i-i4 kuphela kwemoto kwicandelo layo apho ulawulo lwebrake kunye nokusebenza kusebenze kunye ne-booster ye-brake idityaniswe kwimodyuli enye edibeneyo, kunye ne-actuator yombane isetyenziswa. , eyenza uxinzelelo lwebraking ngokukhawuleza kwaye ngokuchanekileyo ngakumbi, ukongeza ekunyatheleni okungaguquguqukiyo kwe-pedali”.
Enye yezona zinto ziqinisekisayo yayiluzinzo olukhulu lweentshukumo zomzimba, ngenxa yokomelezwa kwe-chassis kunye nezixhobo zombane ezisele zikhankanyiwe, kodwa kunye neendlela ezibanzi nge-2.6 cm ngaphambili kunye ne-1.3 cm kwiziko elingasemva nasezantsi. womxhuzulane (53mm ngaphantsi kwi-i4 eDrive40 kwaye ngaphantsi kwe-34mm kwi-i4 M50), isoloko ineSedan 3 sedan njengebhentshi.
Ukusasazwa kobunzima obulinganayo kwi-M (48% -52%) kunenguqulo yokungenela (45% -55%) kunciphisa naziphi na iziphumo ezingalunganga eziveliswa bubunzima bayo obongezelelweyo (2290 kg vs 2125 kg ye-eDrive 40), nayo uncedo lokungenelela kwe-wheel drive yonke, xa ivuliwe, kunye namathayi abanzi angasemva (285 mm vs. 255 mm ngaphambili).
ngaphezulu kwedijithali ngaphakathi
Ukuya esiphelweni ibe luxabiso lwekhabhinethi, eyenziwe ngezinto ezininzi kunye nengqiqo yokusebenza esiyaziyo kwii-BMW zamva nje, ngakumbi i-iX3. Ngokuqhelekileyo ngamanyathelo amaninzi ngaphezu kwento iTesla inikezela ngayo kwiimodeli zayo, zombini kumgangatho wezinto eziphathekayo, ukwakhiwa kunye nokugqiba.
Sineemodyuli zolawulo zakwaBMW ezaziwayo, kodwa zidityaniswe nezikrini ezintsha ezigobileyo (12.3” + 14.9”) zezixhobo kunye ne-infotainment, ezidityaniswa nevili lokuqhuba elitsha ukwenza ifilosofi entsha yokugxila kumqhubi.
Phantse yonke imisebenzi yokusebenza - kwanolawulo lwemozulu - idibaniswe kwisiboniso esigobileyo njengenxalenye yendlela yonke egxininise ekunciphiseni inani lolawulo lomzimba ubuncinane. Kodwa, ngokuchaseneyo nokwenzekileyo kumbono oye wavelisa le i4, umkhethi wegiya weklasikhi akazange atshintshwe sisitshixo.
