Imurikagurisha rya moderi zose zamashanyarazi ziragwira, bikomera kuri Tesla, uzaba agomba kwishyiraho dore ko atakiri wenyine kumasoko. Nk i4 , “coupe y'imiryango ine”, BMW izatera ikirango cya Californiya mubutaka bwayo, ariko kandi na sedan irushanwa yibirango bya "gakondo" bizagaragara kumasoko mumezi ari imbere.
Nibwo bwa kane amashanyarazi yose ya BMW hamwe na classique muri bo, nubwo ibintu bitandukanye. Uhereye kumurongo wikubye kabiri (gukonjesha gukenera ibice byamashanyarazi biri hasi cyane kandi bigahuzwa na lamellae ifite imyanya 10 itandukanye) kugeza kuri diffusers yinyuma (mumwanya wibisohoka), nkuruhande rwo hepfo aho ruri. yashizwemo na batiri, irerekanwa hamwe n'ubururu “i Ubururu”.
Twebwe rero, duhanganye nicyitegererezo cyambere cyamashanyarazi kiva muri BMW kigomba kugera kurwego rwo hejuru rwubushobozi bwimbaraga ziki kirango, kikaba gihwanye na moteri nziza yo gutwika (kandi akenshi hamwe na silinderi nyinshi), gutwara ibiziga byinyuma no kwinezeza, ibiranga abo bahanganye benshi bifuza.
Ntabwo ari moderi itandukanye, nka i3, cyangwa ikinyabiziga cyahinduwe kiva mubyahozeho, nka iX3, mbere cyakozwe kuva kera, hamwe na 4 Series Gran Coupé, hamwe nacyo gitangiye gukorerwa. Munich (uruganda rwakiriye ishoramari rya miliyoni 200 z'amayero kugirango, ku nshuro ya mbere muri BMW, imodoka ifite moteri yaka ndetse n’imodoka y’amashanyarazi 100% ishobora gukorerwa ku murongo umwe).
Kuri metero 4,78 z'uburebure (cm 7 z'uburebure kurenza Urukurikirane rwa 3, ariko hafi yuburebure bumwe kuri m 1,45 na moteri ya moteri 2,85 m), umurimo wabashushanyaga hamwe naba injeniyeri ba aerodinamike wari ukomeye kugirango ubashe kugera kuri coefficient (Cx) ya 0.24 . Imbere yimbere hamwe ninyuma yinyuma, abayobora ikirere imbere yibiziga kandi, nubwo bitagaragara, munsi yimodoka hamwe no gukingira icyuma cya moteri hamwe na batiri, byari bifite filozofiya isanzwe yo gutezimbere inzira ya umwuka.
340 hp kugeza 544 hp, inyuma cyangwa gutwara ibiziga bine
Ku ikubitiro, hazaba verisiyo ebyiri: i4 eDrive40 hamwe na moteri yinyuma yinyuma (340 hp na 430 Nm, gutwara ibiziga byinyuma, umuvuduko wa kilometero 190 / h, kwihuta kuva 0 kugeza 100 km / h muri 5.7s hamwe na 590 km) hamwe na i4 M50 aribwo bwa mbere bwo guhuza amashanyarazi yose hamwe ninyuguti ya M hamwe na bine yimodoka.
Muyandi magambo, ikoresha moteri yamashanyarazi kuri buri axe (imbere ifite 258 hp ninyuma hamwe na 313 hp), kubikorwa bya sisitemu ntarengwa ya 544 hp na 795 Nm, ibi bimaze gukorwa na Sport Boost imikorere ikorwa numushoferi ( ikaba "itera" hp 68 hp na 65 Nm kumasegonda 10). Muri ubu buryo bwo "gukaza umurego", BMW i4 M50 irashobora kurasa kugera kuri 100 km / h muri 3.9s no kugera kuri 225 km / h yumuvuduko wo hejuru, injyana igomba gutuza cyane kugirango ibashe kuguma hafi ya 510 km yo kwigenga.
Imbaraga zinyuzwa mu guhererekanya umuvuduko umwe kumuziga winyuma kuri i4 eDrive40 cyangwa kuri bine zine kuri i4 M50 kandi mugihe gusa aho imiterere yumuhanda itegeka (ubu buryo ubwigenge ntibwangirika cyane).
Mu kwihuta gukomeye kuruhande cyangwa mugusubiza ikibazo cyo gutakaza uruziga, ibiziga byimbere bigira uruhare mukuzamura imikorere ya i40 M50 hamwe numuvuduko mwinshi woherejwe hamwe nubugenzuzi bwuzuye kuruta mbere. Agasanduku ko kohereza hagati yabyo amashoka, usibye ko nta gihombo cyiza giterwa nubushyuhe bwumuriro muri sisitemu ya mashini.
Kurundi ruhande, gukoresha moteri kuri buri murongo nabyo bigira uruhare mukubyara urwego rwo hejuru cyane rwo kugarura ingufu, rushobora kugera kuri 195 kW muri i4 M50, mugihe muri i4 eDrive40 ari 116 kWt gusa. Nkuko David Ferrufino, umuyobozi wumushinga i4 abinsobanurira (kuva akiri ingimbi muri Boliviya yamye ari umufana wimodoka):
David Ferrufino, Umuyobozi wumushinga BMW i4"(…) Birahagije ko, hamwe no gutwara ubushishozi, 90% yo kwihuta bikorwa gusa kugirango bakire kandi nta mpamvu yo gukandagira kuri pederi".
Urwego rwo gukira ni Predictive (ukoresheje amakuru aturuka kuri sensor no kugendana), Hasi, Hagati na Hejuru, kandi birashoboka gusiga uwatoranije itumanaho mumwanya "B", aribwo bukomeye kandi bubereye gutwara hamwe na pedal imwe (gusa trottle) ).
Gukora neza
Igisekuru cya gatanu modulire ya eDrive ya tekinoroji iragaragaza iterambere ryikoranabuhanga rigaragara, hamwe nibice byinshi byuzuzanya hamwe no guhuza neza, ingufu za moteri nyinshi (kwiyongera hafi 50% ugereranije na 2020 i3), 20% byimbaraga za batteri (110 mm hejuru, 561) kg muburemere hanyuma igashyirwa hasi yimodoka hagati yimitambiko yombi) kandi no kwiyongera gukomeye kwingufu zamashanyarazi zemewe na sisitemu (ntarengwa 200 kW).
Izi verisiyo zombi zikoresha bateri imwe ya Li-ion, BMW itanga garanti yimyaka umunani / 160 000. Ifite ubushobozi bwa 83.9 kWh (80.7 kWh net), igizwe na module enye zingirabuzimafatizo 72 hamwe na modul eshatu za selile 12 imwe, yose ni prismatic.
Pompe yubushyuhe yitondera kuzana bateri mubushuhe bwiza bwo gukora byihuse, kimwe no gufasha imirimo yo gushyushya no gukonjesha.
Amafaranga ashobora kwishyurwa muguhinduranya amashanyarazi (AC), imwe (7.4 kW) hamwe nicyiciro cya gatatu (11 kWt, gufata amasaha 8.5 kugirango uve kuri 0 kugeza 100% yumushahara) cyangwa mumashanyarazi ataziguye (DC) kugeza kuri 200 kW ( Kwishyura 10 kugeza 80% muminota 31).
Imikorere ya moteri nshya yamashanyarazi igera kuri 93% (birenze inshuro ebyiri moteri nziza yo gutwika igeraho), bivamo gukoresha make bityo, kwagura ubwigenge.
Ihindagurika ryanashobokaga kubera ko moteri itagifite rotor kugirango itwarwe na magnesi zihoraho (asinchronous or synchronous), kandi ubu zikoreshwa ningufu zamashanyarazi (bita ESM cyangwa BLDC, ni ukuvuga moteri idafite amashanyarazi), hamwe nibyiza yo gukora amashanyarazi atangwa, ako kanya kandi gahoraho, usibye gukuraho ikoreshwa ryibyuma bidasanzwe (bikenewe mubice bya magneti) mugukora rotor.
BMW i4 M50
Kurwanya Tesla Model 3
Twabonye i4 nshya inshuro ebyiri, imwe mu ntangiriro zuyu mwaka iracyari mu mwanya wa shoferi muri verisiyo yinyuma yimodoka (mugihe imodoka yari iyobowe namaboko abizi ya "se" wa i4) kandi vuba aha inyuma yumuzingi wa i4 M50, burigihe kuri BMW test center mumajyaruguru ya Munich.
Ferrufino yashimangiye ko "iyi ari imwe mu modoka zikomeye za BMW mu myaka yashize kuko ifite ubutumwa bwo kugeza ADN mu gihe cya electronique", ndetse no gufata umwanya wo "gukubita" Tesla:
David Ferrufino, Umuyobozi wumushinga BMW i4"Tugomba kuba abizerwa ku muco wo gukora imodoka zishishikariza abayitwara, bityo rero, kwihuta cyane mu murongo ugororotse ntibiri kure yo kuba intego" ...
Ibi ntibisobanura ko, niyo byamenyereye kuba ibindi bicuruzwa bikoresha mugutezimbere imiterere yabo mishya, BMW ntabwo ifata umwanya mushya: "Model 3 ya Tesla yamye ihari muriki gikorwa, kuva yatangira. ”, Yemera Ferrufin.
Ntabwo bitangaje, Model 3 yatumye amashanyarazi 100% ahendutse kandi yifuzwa nabakiriya ibihumbi muri Amerika, Uburayi na Aziya. Ibipimo hamwe nuburinganire bwa moderi zombi birasa kandi nubwo bitanga umwanya mwiza kubantu bane bakuze hamwe nu mutwaro utubutse (470-1290 l), iyi i4 biragaragara ko idakwiriye kubantu batanu, bazahora bakora ingendo ndende cyane kandi ntibyoroshye hagati yimodoka. umurongo wa kabiri wintebe.
Dynamic "kuri BMW"
Kuva aha, itandukaniro ritangira kugaragara, cyane cyane mubijyanye na dinamike, mubintu byose birenze ballistique itangira Tesla iyariyo yose yamenyereye kandi BMW nayo izatanga mumodoka zamashanyarazi.
Ikintu cyagaragaye mubushobozi bwa feri itangaje mbere ya buri murongo, ubushobozi bwo gukomeza inzira no kwihuta byuzuye mbere yo gusubira muburyo bugororotse, burigihe hamwe no guhagarara kwinshi mumikorere yumubiri.
Turi muri moderi idafite imbaraga - i4 eDrive40 - hamwe na moteri yinyuma, ariko hamwe nisoko yumwuka kumurongo winyuma (bisanzwe kuri verisiyo zose), mugihe ibyuma bya elegitoronike bihinduka (biyobora buri ruziga kugiti cye) bizaba mubice bya eDrive40 ibikoresho nibisanzwe kuri M50.
Bimwe mubyiza byerekana inzira iringaniye bifitanye isano na tekinoroji yihariye yo kugabanya kugirango umubiri ugabanuke mugihe cyihuta, kimwe na sisitemu yo kugabanya ibiziga (ARB, yatangiriye kuri i3, ariko hano bwa mbere mubufatanye ibiziga byose) bigira uruhare mukuzamura gukwega no guhagarara neza, ndetse no kunyerera.
Ibi bituma buri ntangiriro ihita kandi nta gutindiganya, ikintu cyarushijeho gusobanuka igihe nafataga ibinyabiziga bya BMW i4 M50. Hano hari igenamiterere ryihariye ryamasoko, dampers hamwe na stabilisateur (byose birakomeye), ihuriro ryinyongera hagati yiminara yimbere, kuyobora siporo ihindagurika (hamwe nimiterere ibiri, imwe itaziguye kandi imwe yorohewe) na feri ya M Sport.
Imwe mu ngingo zatwaye BMW i4 yatunguwe cyane ni iyo gufata feri, gutera imbere no gukomera kuruta imodoka zose z'amashanyarazi natwaye. Ferrufini aramwenyura, mbere yo gusobanura impamvu: "i4 niyo modoka yonyine mu gice cyayo aho imikorere ya feri yo kugenzura no gukora feri hamwe na booster ya feri ihuriweho na module imwe ihuriweho, hiyongereyeho amashanyarazi akoreshwa., Bitanga umuvuduko wa feri vuba kandi kurushaho, hiyongereyeho intambwe ihamye ya pedal ”.
Ikindi kintu cyemeza cyane ni ihinduka rikomeye ryimikorere yumubiri, bitewe nimbaraga za chassis hamwe nibikoresho bya elegitoronike bimaze kuvugwa, ariko nanone inzira yaguka kuri cm 2,6 imbere na cm 1,3 inyuma ninyuma yo hagati ya rukuruzi (53mm munsi kuri i4 eDrive40 na 34mm munsi ya i4 M50), burigihe hamwe na sedan ya Series 3 nkigipimo.
Ikwirakwizwa ryinshi rya misa kuri M (48% -52%) kuruta kuri verisiyo yinjira (45% -55%) igabanya ingaruka mbi zose ziterwa nuburemere bwiyongereye (2290 kg vs 2125 kg kuri eDrive 40), hamwe na ubufasha bwo kwifashisha ibiziga byose, iyo bikora, hamwe nipine nini yinyuma (285 mm na 255 mm imbere).
imbere imbere
Ahagana ku ndunduro kwari ugushimira kabine, igizwe nibintu byinshi hamwe na logique ikora tuzi muri BMW ziherutse, cyane cyane iX3. Mubisanzwe ni intambwe nyinshi hejuru yibyo Tesla itanga mubyitegererezo byayo, haba mubyiza byibikoresho, kubaka no kurangiza.
Dufite modules izwi cyane yo kugenzura BMW, ariko ihujwe na ecran nshya igoramye (12.3 ”+ 14.9”) kugirango ikoreshwe hamwe na infotainment, ihuza hamwe na ruline nshya kugirango ikore filozofiya nshya yo kwibanda kuri shoferi.
Imikorere hafi ya yose ikora - ndetse no kurwanya ikirere - yinjijwe muburyo bugoramye nkigice cyuburyo rusange bwibanze ku kugabanya umubare wigenzura ryumubiri kugeza byibuze. Ariko, bitandukanye nibyabaye mubitekerezo byabyaye iyi i4, uwatoranije ibikoresho bya kera ntabwo yasimbuwe na switch.
