Umuyobozi w'uruhererekane rwa BMW 3/4, Peter Langen, asobanura agira ati: "Ntabwo twashyize igifuniko gitandukanye kuri 3 hanyuma ngo duhindure imibare." BMW 4 Series : “Turashaka ko bitubera scalpel, ni ukuvuga, inzugi z'imiryango ibiri zikarishye cyane, zaba stiliste kandi zifite imbaraga”.
Niba kandi ubu bwoko bw'imvugo burimo kwamamaza cyane kuruta ikindi kintu cyose, muriki gihe biroroshye kubona ko, mubyukuri, tutakunze kubona BMW coupe itandukanye cyane na sedan isangiye na base, moteri, ikibaho. na byose. byinshi.
Twari tumaze kugira manifeste yiyi ntego hamwe na Concept 4 (yerekanwe kumurikagurisha ryanyuma rya Frankfurt) kandi kubijyanye nimirongo yoroheje, hiyongereyeho impyiko ebyiri zagabanutseho gato, cyane cyane ko imodoka yubushakashatsi yanenzwe kubera gushira amanga.
Ariko birahinduka cyane, gato nkuko tubizi kumashanyarazi ya i4, ariko ikiruta byose, impyiko zihagaritse ni ukubaha kahise kuko zabanje kugaragara mubyitegererezo byabigani - uyumunsi bifite agaciro gakomeye - nka BMW 328 na BMW 3.0 CSi.
Noneho, ikarishye ikarishye mubikorwa byumubiri, ikibuno kizamuka hamwe nubuso bwometse hejuru kuruhande rwinyuma, hepfo no mugari (ingaruka zishimangirwa na optique igera kumpande zumubiri), imitsi ninkingi yinyuma yinyuma nini nini Idirishya ryinyuma hafi ya risa nicyitegererezo kidashingiye kuri 3 Series, gishimangira imiterere yacyo.
Iyandikishe mu kanyamakuru kacu
Niba mu gisekuru cyabanjirije twatangiye kubona uku gutandukana kwa coupe na sedan, ndetse hamwe nizina ritandukanye (3 na 4), ubu ibintu byose birasobanuka neza hamwe nuburyo butandukanye buzashimisha abashobora kugura siporo yimibiri yombi byinshi.
byinshi bihujwe n'umuhanda
Uburebure bwariyongereyeho cm 13 (kugeza kuri 4,76 m), ubugari bwiyongereyeho cm 2,7 (kugeza kuri m 1,852) naho uruziga rurambuye kuri cm 4,11 (kugeza kuri m 2,851). Uburebure bwiyongereyeho 6mm gusa kububanjirije (kugeza kuri 1.383m), bituma imodoka 5.7cm iba ngufi kurenza Urukurikirane 3. Inzira ziyongereye ugereranije nabayibanjirije - 2.8cm imbere na cm 1.8 inyuma - ikaba ikiri ubugari bwa cm 2,3 kurenza Urukurikirane rwa 3.
Ku rundi ruhande, ibiziga by'imbere ubu bifite camber mbi kandi inkoni za karuvati zongewe kumurongo winyuma kugirango byongere ubukana bwa "local", nkuko Langen akunda kubyita, kandi ibyuma bikurura amashanyarazi bifite sisitemu yihariye ya hydraulic, kimwe na mu rukurikirane rwa 3.
Imbere, buri cyuma gikurura gifite hydraulic ihagarara hejuru yongera imbaraga zo kwisubiraho, naho inyuma piston ya kabiri itanga imbaraga nyinshi zo kwikuramo. "Nuburyo imodoka ikomeza guhagarara neza", bifite ishingiro umuyobozi wa dinamike Albert Maier, nawe ufite uruhare runini mugutezimbere imbaraga za BMW 4 Series.
Izi mpinduka zajyanye nubusobanuro bushya bwa software, kuyobora hamwe numubare wihariye hamwe nuburyo bwo gutwara butanga uburenganzira bwubwisanzure kubatwara, niba aribyo bashaka: "imodoka igomba kwemerera umushoferi kuba mwiza nkuko abitekereza." , amwenyura Langen, hanyuma yemeza ko "umumarayika murinzi aracyari hejuru, gusa aguruka hejuru gato".
Amatara ya LED arasanzwe, mugihe amatara yo guhuza amatara ya LED hamwe na laser arahari nkuburyo bwo guhitamo, aherekejwe n'amatara yunamye hamwe n'imikorere yo guhuza imihindagurikire y'ikirere hamwe n'amatara ahinduka ateganijwe gutwara mumijyi no mumihanda. Ku muvuduko uri hejuru ya 60 km / h, BMW Laserlight yongerera itara kugeza kuri m 550, bigenda bikurikirana inzira yumuhanda.
mu cyicaro cy'abashoferi
Kwinjira mu kabari kuruhande rwibumoso imbere bivuze kuzengurutswe na ecran ya digitale nko muri BMW zose nshya, ariko zikaba ziherutse kugera muri uru rwego, zimaze kurenga imyaka mirongo ine yubuzima hamwe na miliyoni 15 zanditswe kwisi yose (muri iri soko ryubushinwa rimaze kuba rinini kurwego rwisi).
Ihuza ryiza cyane ryibikoresho hamwe na ecran yo hagati irashimishije (muribintu byombi birashobora kugira ubunini butandukanye, kuba digitale rwose kandi igaragara). Hagati ya konsole hagati ihuza buto yo gutwika moteri, hamwe na iDrive mugenzuzi, uburyo bwo gutwara ibinyabiziga na buto ya feri yo guhagarara (ubu amashanyarazi).
Nibyihuse kandi byoroshye kugera kumwanya mwiza wo gutwara ndetse nabashoferi barebare ntibumva ko bagufi: kurundi ruhande, ibintu byose byiteguye gutanga kugirango bashobore gusohoza inshingano zabo zingenzi. Ibikoresho hamwe nubwiza bwiteraniro nibirangiza ni urwego rwiza, nkuko tubizi murukurikirane rwa 3.
Moteri ya BMW 4 Series
Urutonde rwa BMW 4 Series nshya igizwe kuburyo bukurikira:
- 420i - 2.0 l, silinderi 4, 184 hp na 300 Nm
- 430i - 2.0 l, silinderi 4, 258 hp na 400 Nm
- 440i xDrive - 3.0 l, silinderi 6, 374 hp na 500 Nm
- 420d / 420d xDrive - 2.0 l, silinderi 4, 190 hp na 400 Nm nayo muri verisiyo ya xDrive (4 × 4)
- 430d xDrive - 3.0 l, silinderi 6, 286 hp na 650 Nm (2021)
- M440d xDrive - 3.0 l, silinderi 6, 340 hp na 700 Nm) (2021)
Kugenzura 430i…
Icya mbere muri moteri twahawe "uburyohe" ni moteri ya 258 hp 2.0 ikoresha 430i, nubwo tutaramenyera neza igitekerezo cyuko "30" ikoresha blok ya silindari enye gusa.
Nyuma yo kurangiza ibizamini byiterambere byimbaraga kuri Arctic Circle (Suwede), kumuhanda wa Miramas (mumajyaruguru ya Marseille) kandi, byanze bikunze, kuri Nürburgring, aho abajenjeri ba chassis bakunda gukora "ikizamini cya cyenda", twahawe amahirwe yo gutwara BMW 4 Series.
Ikibanza cyatoranijwe cyari kumurongo wikizamini kandi biracyaza… hamwe nibikorwa byafashwe amashusho, kuko nyuma yaho gusa amashusho yimodoka "yambaye ubusa", ubu turakwereka, azamenyekana.
Ariko ni verisiyo yemeza, kuvuga make: ntiwigera wumva ko moteri ibura "roho", bitandukanye cyane, kandi imirimo ikorwa kuri acoustics ibasha guhisha igihombo cya silindiri ebyiri, utiriwe ukabya inshuro ya digitale yoherejwe na sisitemu amajwi, igaragara cyane muburyo bwo gutwara siporo.
Nubwo bimeze bityo aho iyi 430i igaragara cyane nubushobozi bwayo bwo kumira imirongo. niyo twabajugunya muri bo nta bushishozi bukomeye cyangwa ubushishozi busanzwe, ndetse no muri iyi verisiyo hamwe na "metallic" ihagarikwa ifashwa na kg 200 keretse iyo igomba guhura na 440i xDrive, bigatuma umutambiko w'imbere ugenda wihuta mubitekerezo.
Motricity nikindi kintu cyaranze, nanone kuko muriki gihe dufite intervention yo kwifungisha itandukaniro (itabishaka) inyuma, igashira iherezo ryikigeragezo icyo ari cyo cyose cyo kunyerera mugihe dufasha gushyira imbaraga hasi.
Birakwiye gushimirwa kubuyobozi, cyane cyane nkuko BMW ubu "itagitekereza" ko kugira uruziga ruremereye burigihe bisa na siporo. "Data" nyayo ihora ihererekanwa kubyerekeye isano yibiziga na asfalt nta gisubizo giteye ubwoba kiri hagati.
Na M440i xDrive
M440i xDrive ni ya kalibiri itandukanye, hamwe na 374 hp itangwa na moteri itandatu ya moteri. Kandi bashyigikiwe kandi na moteri yumuriro wa 8 kW / 11 hp, idufasha kubisobanura nkibintu byoroheje-bivangwa na tekinoroji ya 48 V.
Michael Rath, ushinzwe iterambere ry’iyi moteri, yatangiye kugaragara mu mezi make ashize muri 3 Series, asobanura ko “hashyizweho uburyo bushya bwo kwishyiriraho ingufu za turbocharger ebyiri, igihombo cya inertia cyagabanutseho 25% kandi ubushyuhe bw’umuriro bwiyongereye (kugeza 1010º C), byose bigamije kugera kubisubizo byiza no gutanga umusaruro mwinshi, muriki gihe ntabwo munsi yinyongera 47 hp (374 hp ubungubu) na 50 Nm zirenga (500 Nm peak). Kandi ibyo bigambanira kugana kwihuta nka 4.5 s kuva 0 kugeza 100 km / h neza barabigaragaza.
Ibisohoka by'amashanyarazi ntibikoreshwa gusa mugushigikira kwihuta (bigaragara mugutangira no kwihuta gusubukurwa), ariko kandi no "kuzuza" intambamyi ngufi cyane mugutanga amashanyarazi mumashanyarazi yimashanyarazi ifite ubushobozi bwihuse bwohereza umunani-yihuta ya Steptronic, kunshuro yambere, yashyizwe muburyo bwose bwa BMW 4 Series Coupé.
Hariho kandi na verisiyo ya Steptronic ya verisiyo imwe yoherejwe, isanzwe kuri verisiyo ya M kandi ihitamo kubindi bisobanuro byerekana, hamwe nibisubizo byihuse - nanone ibisubizo byimikorere mishya ya Sprint - hamwe na podiyumu ya gare ya shitingi.
Ikindi kintu cyagaragaye muri kilometero zumuhanda ni uko feri ya M Sport yongerewe imbaraga - ibyuma bine bya piston enye byashyizwe imbere kuri disiki ya mm 348 hamwe na kaliperi imwe ireremba kuri disiki ya mm 345 inyuma - byihanganiye "kuvura ihungabana. ”Nibyiza. Byakorewe, utabonye ibimenyetso byumunaniro bikunze kugaragara muri sisitemu zisanzwe zifata feri mugihe zashyizwemo imbaraga ziyi mbaraga.
Kandi byashobokaga no kubona ibikorwa byinyuma bigarukira-kunyerera (electronique). Ahanini kumurongo ucuramye, aho usanga uruziga rwimbere rugana kumurongo kunyerera munsi yihuta rugabanuka cyane, kuko clutch ifunze, guhuza torque kumuzinga winyuma ugana kumurongo no gusunika imodoka imbere, mugihe amategeko ya fiziki gerageza kukurasa.
Muri ubu buryo, M440i xDrive (nayo ifashwa na moteri yimodoka enye) irashobora kugira igihombo gito, mugihe ituze hamwe no guhanura ibisubizo byunguka.
