Soo bandhigida moodooyinka korantada oo dhan way bataan, iyagoo adkeynaya xajinta Tesla, kaas oo noqon doona inuu awood u yeesho inuu naftiisa ku soo rogo hadda oo uusan kaligiis ku jirin suuqa. Sida i4 , "Coupé afar-albaab ah", BMW waxay weerari doontaa astaanta Californian ee dhulkeeda, laakiin sidoo kale sedans tartanka ah ee noocyada "dhaqameed" kuwaas oo ka muuqan doona suuqa bilaha soo socda.
Kani waa BMW-kii afraad ee dhammaan-korontada ah, waana kan ugu qadiimiga ah ee iyaga ka mid ah, in kasta oo ay jiraan waxyaabo kala duwan. Laga soo bilaabo cirifka labajibbaaran ee daboolan (baahida qaboojinta ee qaybaha korantada korantada ayaa aad u hooseeya waxaana lagu hagaajiyaa lamellae oo leh 10 jagooyin kala duwan) ilaa diffusers gadaal (meel ka mid ah meelaha qiiqa) kaas oo, sida dhinaca hoose ee meesha uu ku yaal. baytari ku rakiban yihiin, waxaa lagu iftiimiyay jar buluug ah "i Blue".
Sidaa darteed, waxaanu wajahaynaa qaabka ugu horreeya ee korantada ee BMW kaas oo ah inuu gaaro heerka sare ee kartida firfircoon ee astaantan, taas oo la mid ah matoorada gubashada ee aad u fiican (iyo inta badan oo leh dhululubo badan), wadista gawaarida iyo raaxada wadista, sifooyinka. taas oo dad badan oo xafiiltamaan ah ay u hanqal taagayaan.
Ma aha nooc gaar ah, sida i3, ama baabuur laga beddelay mid hore u jiray, sida iX3, oo markii hore laga soo saaray xoq, oo ay weheliyaan 4 Series Gran Coupé, oo ay weheliyaan kaas oo hadda la bilaabay in la soo saaro. Munich (warshad heshay maalgelin dhan 200 milyan oo Yuuro si, markii ugu horreysay ee BMW, baabuur leh mishiin gubanaya iyo 100% baabuur koronto ah ayaa lagu soo saari karaa isla khadka isku midka ah).
Dhererka 4.78 m (7 cm ka dheer Taxanaha 3, laakiin qiyaastii isla dhererka 1.45 m iyo wheelbase 2.85 m), shaqada naqshadeeyayaasha iyo injineerada aerodynamic waxay ahayd mid aad u adag si ay u awoodaan inay gaaraan iskudarka (Cx) ee 0.24 . Deflectors hore iyo diffusers gadaal, hagayaasha hawada ee hortooda taayirrada iyo, xitaa haddii aan la arki karin, undercarriage ee baabuurka iyo gaashaanka ee qaybta engine iyo dahaarka batari, lahaa sida falsafada caadiga ah hagaajinta marinka ee hawada.
340 hp ilaa 544 hp, gadaal ama afar taayir
Ugu horreyntii, waxaa jiri doona laba nooc: i4 eDrive40 oo leh mashiinka korantada ee gadaale (340 hp iyo 430 Nm, wadista gawaarida, xawaaraha ugu sarreeya ee 190 km / h, dardargelinta 0 ilaa 100 km / h 5.7s iyo kala duwanaansho 590 km) iyo i4 M50 oo ah bilawga isku dhafka dhammaan korantada oo dhan xarafka M iyo wadista afarta taayir leh.
Si kale haddii loo dhigo, waxay isticmaashaa matoor koronto ah gees kasta (hore oo leh 258 hp iyo gadaal oo leh 313 hp), waxqabadka ugu sarreeya ee 544 hp iyo 795 Nm, tani waxay horeyba ula shaqeysay Kordhinta Isboortiga ee uu kiciyay darawalka ( kaas oo "duray" 68 hp oo dheeraad ah iyo 65 Nm ilaa 10 ilbiriqsi). Qaabayntan “gardarrada leh” ee dheeraadka ah, BMW i4 M50 waxay awood u leedahay in ay toogto ilaa 100 km/h 3.9s oo ay gaadho 225 km/h ee xawliga ugu sarreeya 510 km oo madax-banaani loo ballan qaaday.
Awoodda waxa la mariyaa gudbinta hal xawli ah oo loo gudbiyo taayirrada dambe ee i4 eDrive40 ama afarta taayir ee i4 M50 iyo keliya xaaladaha xaaladaha taraafikada ay sidaas u sheegaan (sidan oo kale madaxbannaanida si xad dhaaf ah uma liidato) .
Dardargelinta dhinaca dambe ee xooggan ama ka jawaabista luminta jiidista taayirrada, taayirrada hore waxay ka qayb qaataan mas'uuliyadda kicinta si ay u hagaajiyaan maaraynta guud ee i40 M50 oo leh xawaare wareejin aad u sarreeya iyo kontorool sax ah oo ka badan sidii hore. faashashka, marka lagu daro ma jiraan wax khasaare ah oo waxtarka leh oo ay sababaan culeysyada kulaylka ee nidaamka makaaniknimada.
Dhanka kale, isticmaalka mishiinka dhidib kasta wuxuu sidoo kale ka qaybqaataa abuurista heer aad u sarreeya oo soo kabasho tamar ah, kaas oo gaari kara 195 kW i4 M50, halka i4 eDrive40 uu yahay 116 kW oo keliya. Sida David Ferrufino, oo ah agaasimaha mashruuca i4 uu ii sharraxay (kaas oo tan iyo waayihiisii dhallinyaranimada ee Bolivia uu had iyo jeer ahaa nin baabuur jecel):
David Ferrufino, Agaasimaha Mashruuca BMW i4"(...) waa ku filan tahay, iyadoo si cadaalad ah loo wado, 90% deceleration waxaa loo sameeyaa kaliya soo kabashada iyo iyada oo aan loo baahnayn in lagu talaabsado badhka biriiga".
Heerarka soo kabashada waa Saadaal (adiga oo isticmaalaya macluumaadka dareemayaasha iyo navigation), Low, Dhexdhexaad iyo Sare, waxaana suurtagal ah in laga tago xulashada gudbinta booska "B", kaas oo ah kan ugu xooggan uguna habboon in lagu wado hal badar (kaliya ceejinta ).
Waxtarka badan
Jiilka shanaad ee tignoolajiyada dhaqaajinta eDrive waxay calaamad u tahay horumarka tignoolajiyada cad, oo leh qaybo badan oo is haysta iyo isdhexgal ka wanaagsan, cufnaanta tamarta sare (qiyaastii 50% korodhka marka loo eego 2020 i3), 20% cuf cufnaanta sare ee baytariyada (110 mm sare, 561) kg miisaanka oo lagu dhejiyay dabaqa baabuurka ee u dhexeeya labada geesood) iyo sidoo kale koror weyn oo ku yimaada awoodda dallacaadda ee uu aqbalay nidaamka (ugu badnaan 200 kW).
Labada noocba waxay isticmaalaan batari isku mid ah oo Li-ion ah, kaas oo BMW uu siinayo sideed sano / 160 000 km damaanad warshadeed. Waxay leedahay awood ah 83.9 kWh (80.7 kWh net), waxay ka kooban tahay afar qaybood oo midkiiba 72 unug ah iyo saddex qaybood oo midkiiba 12 unug ah, dhammaantoodna asal ahaan.
Bamka kulaylku waxa uu daryeelaa in uu batteriga u keeno heer kul hawleed ku habboon sida ugu dhakhsaha badan, iyo sidoo kale caawinta hawlaha kululaynta iyo qaboojinta qolka.
Kharashka waxaa lagu samayn karaa beddelka hadda (AC), hal (7.4 kW) iyo saddex waji (11 kW, qaadashada 8.5 saacadood si ay uga baxdo 0 ilaa 100% ee kharashka) ama hadda (DC) ilaa 200 kW ( 10 ilaa 80% dallaca 31 daqiiqo gudaheed).
Waxtarka matoorada cusub ee korontadu waxa ay gaartaa 93% (in ka badan laba jibaar waxa ay gaadhaan matoorada gubashada ugu fiican), taas oo keenta isticmaalka hoos u dhaca iyo, sidaa awgeed, madax-bannaani dheeraad ah.
Horumarkan ayaa sidoo kale suurtagal ahaa sababtoo ah matoorada mar dambe ma haystaan rotors si ay u kiciyaan magnets joogto ah (isku-dhafka ama synchronous), oo hadda waxaa ku shaqeeya tamar koronto (oo loo yaqaan ESM ama BLDC, taas oo ah, matoor toos ah oo toos ah) , iyada oo faa'iidada leh. samaynta cufan gaarsiinta korantada, degdeg ah oo joogto ah, marka lagu daro baabi'inta isticmaalka biraha dhifka ah (lagama maarmaan u ah qaybaha magnetic) ee soo saarista rotor-ka.
BMW i4 M50
Nooca Anti-Tesla 3
Waxaan ku aragnay i4-ka cusub laba jeer, mid horraantii sanadkan ayaa weli ku jira booska wada-hawlgalaha ee nooca wadista-wheelka (halka baabuurka lagu hagayo gacmaha aqoonta ee "aabbaha" i4) iyo dhawaanahanba mar hore. gadaashiisa giraangiraha i4 M50, had iyo jeer ku yaal xarunta tijaabada BMW ee waqooyiga Munich.
Ferrufino wuxuu ku adkeystay in "tani ay tahay mid ka mid ah baabuurta BMW ugu muhiimsan sannadihii la soo dhaafay, sababtoo ah waxay leedahay ujeedo ah in ay u gudbiso DNA-da xilliga electromobility", iyo sidoo kale qaadashada fursada ah in ay "ku garaacdo" Tesla:
David Ferrufino, Agaasimaha Mashruuca BMW i4"Waa inaan daacad u noqonaa dhaqanka samaynta baabuurta dhiirigelisa kuwa wada, sidaas darteed, kaliya inaad si weyn ugu degdegto bilawga tooska ah waa ka fog tahay hadaf"...
Tani macnaheedu maaha, xitaa haddii loo isticmaalo inay noqoto tixraaca ay noocyada kale u isticmaalaan horumarinta moodalkooda cusub, BMW ma qaadanayso boos cusub: "Tesla's Model 3 had iyo jeer waxay ku jirtay mashruucan, tan iyo markii la aasaasay. ”, ayuu qirtay Ferrufin.
La yaab ma leh, Model 3 wuxuu sameeyay 100% socodka korantada oo la awoodi karo oo ay rabaan kumanaan macaamiisha Mareykanka, Yurub iyo Aasiya. Cabbirka iyo saamiga labada nooc ayaa ku dhow isku mid, inkastoo ay bixiso meel wanaagsan oo loogu talagalay afar qof oo waaweyn iyo qolal boorsooyin deeqsi ah (470-1290 l), i4 si cad uma habboona qof shanaad ah, kaas oo had iyo jeer u safri doona mid aad u adag. oo aan ku raaxaysanayn badhtanka baabuurka, safka labaad ee kuraasta.
Dhaqdhaqaaqa "ee BMW"
Halkan laga bilaabo, kala duwanaanshuhu waxay bilaabaan in la calaamadiyo, gaar ahaan marka la eego dhaqdhaqaaqa dhaqdhaqaaqa, wax kasta oo ka baxsan ballistic bilawga ah in Tesla kasta oo horeba noo bartay iyo in BMW ay sidoo kale ku bixin doonto baabuurteeda korontada.
Wax ka muuqday awoodda bareeg ee cajiibka ah ka hor qalooca kasta, awoodda lagu ilaalinayo jihada iyo in si buuxda loo dardargeliyo ka hor intaysan ku soo laaban toosan, had iyo jeer leh xasillooni badan oo dhaqdhaqaaqa jirka ah.
Waxaan ku jirnaa qaabka ugu awoodda yar - i4 eDrive40 - oo leh darawal gadaal-wheel ah, laakiin leh ilo hawo leh xagasha dambe (heerka dhammaan noocyada), halka dampers elektiroonigga ah oo doorsooma (kuwaas oo maamula taayir kasta si gaar ah) ay noqon doonaan qayb ka mid ah ikhtiyaarka eDrive40 qalabka iyo heerka on M50.
Qayb ka mid ah mudnaanta jidka ayaa dareemay dheelitirka tignoolajiyada gaarka ah ee qoynta si loo dhimo dhaqdhaqaaqa jidhka ee hoos u dhacaya inta lagu jiro dardargelinta, sidoo kale nidaamka xaddidaadda taayirrada taayirrada (ARB, oo laga dooday i3, laakiin halkan waa markii ugu horreysay iyada oo lala kaashanayo wadista taayirrada oo dhan) waxay ka qayb qaadataa soo jiidashada hagaajinta iyo xasiloonida jihada, xitaa dusha simbiriirixan.
Tani waxay ka dhigaysa mid kasta oo bilaabma mid degdeg ah oo aan ka labalabayn, wax sii caddaaday markii aan la wareegay isteerinka BMW i4 M50. Halkan waxaa ku yaal goobo gaar ah oo loogu talagalay ilaha, dampers iyo baararka xasilinta (dhammaan kuwa aad u adag), isku xirka dheeraadka ah ee ka dhexeeya munaaradaha ganaaxa hore, isteerinka isboortiga ee isbeddelaya (oo leh laba goobood, mid toos ah iyo mid raaxo leh) iyo biriiga M Sport.
Mid ka mid ah qodobbada darawalnimada BMW i4 ee sida aadka ah ula yaabay waxa ka mid ahaa bareegga, ka horusocodnimada iyo awoodda baabuur kasta oo koronto ah oo aan watey. Ferrufini wuu dhoola cadeynayaa, ka hor inta uusan sharraxin sababta: "i4 waa gaariga kaliya ee qaybtiisa ka mid ah halka kantaroolka biriiga iyo firfircoonida uu shaqeeyo iyo xoojiye bireega lagu daro hal module oo is haysta, oo lagu daray qalab koronto ayaa la isticmaalaa. si sax ah, marka lagu daro talaabooyin joogto ah oo badheelka ah”.
Mid kale oo ka mid ah dhinacyada ugu qanisan ayaa ahaa xasilloonida weyn ee dhaqdhaqaaqa jidhka, taas oo ka dhalatay xoojinta chassis iyo qalabka elektaroonigga ah ee horay loo soo sheegay, laakiin sidoo kale waddooyinka ballaaran ee 2.6 cm ee hore iyo 1.3 cm ee dambe iyo hoose ee dhexe. cuf-jiidadka (53mm ka yar i4 eDrive40 iyo in ka yar 34mm ee i4 M50), had iyo jeer leh Taxanaha 3 sedan ahaan halbeeg ahaan.
Qaybinta tirada badan ee loo siman yahay ee M (48% -52%) marka loo eego nooca gelitaanka (45% -55%) waxay baabi'isaa saameyn kasta oo taban oo ka dhalata miisaankeeda dheeriga ah (2290 kg vs 2125 kg ee eDrive 40), sidoo kale leh Caawinta faragelinta taayirrada taayirrada oo dhan, marka la dhaqaajiyo, iyo taayirada dambe ee ballaadhan (285 mm vs. 255 mm xagga hore).
dheeraad ah gudaha digital
Gebagebadii waxaa loo mahad naqayay kabiinka, oo ka kooban dhowr walxood iyo caqli-gal hawleed oo aynu ognahay BMW-yadii dhawaa, gaar ahaan iX3. Guud ahaan waa tallaabooyin badan oo ka sarreeya waxa Tesla ay ku bixiso moodooyinkeeda, labadaba tayada alaabta, dhismaha iyo dhamaystirka.
Waxaan leenahay modules gacanta BMW si fiican u yaqaan, laakiin lagu daray shashadaha qalooca cusub (12.3 "+ 14.9") ee qalabaynta iyo infotainment, kuwaas oo la isku daraa isteerinka cusub si ay u abuuraan falsafada cusub ee diiradda on darawalka.
Ku dhowaad dhammaan hawlaha hawlgalka - xitaa xakamaynta cimilada - ayaa lagu dhex daray bandhigga qaloocan taas oo qayb ka ah habka guud ee diiradda saaraya dhimista tirada kontaroolada jirka ilaa ugu yaraan. Laakiin, liddi ku ah wixii ku dhacay fikradda keentay i4 kan, xulashada qalabka caadiga ah laguma beddelin beddelaad.
