“Asizange nje sibeke ikhava eyahlukileyo kwi-3 Series kwaye sitshintshe idijithi,” ucacisa uPeter Langen, umlawuli woluhlu lweBMW 3/4, phambi kokuba agqibezele umbono wento ayifunayo kule intsha. BMW 4 Series : "sifuna ukuba ibe yi-scalpel yethu, oko kukuthi, inguqulo yeminyango emibini ibe bukhali kakhulu, zombini i-stylistic kunye ne-dynamic".
Kwaye ukuba olu hlobo lwentetho luhlala luthengiswa ngakumbi kunayo nayiphi na enye into, kule meko kulula ukubona ukuba, enyanisweni, asifane sibone i-BMW coupé yahluke kakhulu kwi-sedan apho yabelana ngayo ngesiseko esiqengqelekayo, iinjini, ideshibhodi. nayo yonke into.
Sasisele sinayo i-manifesto yale njongo kunye ne-Concept 4 (etyhilwe kwi-Frankfurt Motor Show yokugqibela) kwaye ngokumalunga nokuba imigca ethile yathanjiswa, ukongeza kwizintso eziphindwe kabini ziye zancipha kancinci, ngakumbi kuba imoto yovavanyo yagxekwa. ngokuba nobuganga obukhulu.
Kodwa iba nkqo ngakumbi, kancinane njengoko siyayazi kumbane we-i4, kodwa ngaphezu kwayo yonke loo nto, ezi zintso zithe nkqo ziyintlonipho yexesha elidlulileyo kuba zazibonwa okokuqala kwiimodeli zasentsomini - namhlanje iiklasikhi ezixabiseke kakhulu - njengeBMW 328. kunye neBMW 3.0 CSi.
Emva koko, i-creases ebukhali kumzimba womzimba, i-waistline ekhulayo kunye nomphezulu okhazimlayo kwicala elingasemva, umva ophantsi kunye nobanzi (isiphumo esomelezwe yi-optics eya emacaleni omzimba), intsika yangemva yemisipha kunye neyongeziweyo kunye nenkulu. ifestile yangasemva iphantse yenza ukuba ijongeke njengemodeli ezimeleyo kwi-3 Series, iqinisa ubuntu bayo.
Bhalisa kwincwadana yethu
Ukuba kwisizukulwana sangaphambili saqala ukubona oku kwahlulwa kwe-coupe kunye ne-sedan, kunye ne-nomenclatures eyahlukileyo (3 kunye ne-4), ngoku yonke into iya icace ngakumbi ngezitayile ezicandiwe ngokwenene eziya kukholisa abathengi abanokubakho be-sportier yale mizimba mibini. kakhulu.
ngakumbi eqhagamshelwe endleleni
Ubude banda ngo-13 cm (ukuya kwi-4.76 m), ububanzi banda ngo-2.7 cm (ukuya kwi-1.852 m) kunye ne-wheelbase yoluliwe 4.11 cm (ukuya kwi-2.851 m). Ukuphakama waba nokwanda okushiyekileyo nje 6mm phezu owandulelayo (ukuya 1.383m), ukwenza imoto 5.7cm mfutshane ngaphezu Series 3. Iingoma ziye zanda xa kuthelekiswa nesizukulwana sangaphambili - 2.8cm ngaphambili kunye 1.8 cm ngasemva - leyo nangoku 2.3 cm ububanzi ngaphezu Series 3.
Kwelinye icala, amavili angaphambili ngoku anecamber embi kakhulu kunye neentonga zokubopha zongezwa kwi-asi engasemva ukunyusa ukuqina kwe-torsional “local”, njengoko uLangen ethanda ukuyibiza, kwaye i-absorbers ezothusayo ngoku zinenkqubo ethile ye-hydraulic, njenge. kuthotho 3.
Ngaphambili, i-absorber nganye yokothuka ine-hydraulic stop phezulu eyonyusa ukuxhathisa kwi-rebounds, kwaye ngasemva ipiston yesibini yangaphakathi ivelisa amandla oxinzelelo ngakumbi. "Yiloo ndlela imoto igcinwe izinzile ngakumbi", ithethelela inkosi ye-dynamics u-Albert Maier, oyeyona nto ibalulekileyo kuphuhliso oluguqukayo lwe-BMW 4 Series entsha.
Olu tshintsho luhamba kunye neenkcazo zesoftware entsha, ukulawulwa ngamanani athile kunye neendlela zokuqhuba ezisebenza ukuvumela inkululeko engakumbi kwabo baqhubayo, ukuba yiloo nto abayifunayo: "imoto kufuneka ivumele umqhubi ukuba abe mhle njengoko ecinga ukuba unjalo." , uyancuma uLangen, emva koko uqinisekisa ukuba "ingelosi engumgcini isekho phezulu, ibhabha nje phezulu kancinci".
Izibane ze-LED zisemgangathweni, ngelixa izibane ze-LED eziguquguqukayo kunye ne-laser ziyafumaneka njengenketho, zihamba kunye nezibane zokugoba kunye nemisebenzi ye-anglering eguquguqukayo kunye nokukhanyisa kwendlela eguquguqukayo elungiselelwe ukuqhubela idolophu kunye nomgwaqo omkhulu. Ngesantya esingaphezulu kwe-60 km/h, iBMW Laserlight yonyusa uluhlu lwezibane zentloko ukuya kuthi ga kwi-550 m, ngokuguquguqukayo ilandela indlela yendlela.
kwisitulo somqhubi
Ukungena kwikhabhini kwicala lasekhohlo kwicala langaphambili kuthetha ukuba ujikelezwe zizikrini zedijithali njengakuzo zonke iiBMW ezintsha, kodwa ezisanda kufika kolu luhlu, olusele lugqithile kumashumi amane eminyaka yobomi kunye neeyunithi ezibhalisiweyo ezizizigidi ezili-15 kwihlabathi liphela (kwi- le imarike yaseTshayina sele iyeyona inkulu kwihlabathi jikelele).
Ukudityaniswa okuhle kakhulu kwesixhobo kunye nesikrini esiphakathi sikholisa (kuzo zombini iimeko zinokuba nobukhulu obuhlukeneyo, zibe yidijithali ngokupheleleyo kwaye ziqwalaselwe). I-centre console ngoku idibanisa iqhosha lokulayita injini, ecaleni kwesilawuli se-iDrive, iiswitshi zemowudi yokuqhuba kunye neqhosha lebhuleki yokupaka (ngoku lisebenza ngombane).
Kuyakhawuleza kwaye kulula ukuya kwindawo efanelekileyo yokuqhuba kwaye nabaqhubi abade baziva bexinana: ngokuchaseneyo, yonke into ilungile ukunikelwa ukuze bafezekise umsebenzi wabo obalulekileyo. Izixhobo kunye nomgangatho wokuhlanganisa kunye nokugqiba zikumgangatho olungileyo, njengoko sizazi kwiSeries 3.
Iinjini zeBMW 4 Series entsha
Uluhlu lweBMW 4 Series entsha lwenziwe ngolu hlobo lulandelayo:
- 420i — 2.0 l, 4 iisilinda, 184 hp kunye 300 Nm
- 430i — 2.0 l, 4 iisilinda, 258 hp kunye 400 Nm
- 440i xDrive — 3.0 l, 6 iisilinda, 374 hp kunye 500 Nm
- 420d/420d xDrive — 2.0 l, 4 cylinders, 190 hp kunye 400 Nm kwakhona kuguqulelo xDrive (4×4)
- 430d xDrive — 3.0 l, 6 iisilinda, 286 hp kunye 650 Nm (2021)
- M440d xDrive — 3.0 l, 6 iisilinda, 340 hp kunye 700 Nm) (2021)
Kulawulo lwe-430i…
Eyokuqala yee-injini esizinikwe "ukungcamla" yi-injini ye-258 hp 2.0 enika amandla i-430i, nangona singekayisebenzisi ngokupheleleyo ingcamango yokuba "30" isebenzisa ibhloko yeesilinda ezine nje.
Emva kokugqiba iimvavanyo zophuhliso oluguquguqukayo kwi-Arctic Circle (eSweden), kwindlela ye-Miramas (emantla eMarseille) kwaye, eNürburgring, apho iinjineli ze-chassis zithanda ukwenza "uvavanyo lwabo lwesithoba", sanikwa ithuba lokuqhuba iBMW 4 Series entsha.
Indawo ekhethiweyo yayikwingoma yovavanyo lwebrendi kwaye ise… ngomzimba ofihliweyo, kuba kuphela emva kwexesha apho imifanekiso esemthethweni yemoto “ize”, esikubonisa yona ngoku, iya kutyhilwa.
Kodwa yinguqulelo ekholisayo, ukutsho okuncinci: awusoze uzive ngathi injini ayinayo "umphefumlo", ngokuchaseneyo, kwaye umsebenzi owenziwe kwi-acoustics ulawula ukufihla ilahleko yeesilinda ezimbini, ngaphandle kokubaxa iifrikhwensi zedijithali ezithunyelwe iaudio yenkqubo, eyona iphawuleka kakhulu kwiindlela zokuqhuba zemidlalo.
Nangona kunjalo apho le 430i igqame kakhulu kukukwazi ukuginya amagophe. nokuba siyijula kubo ngaphandle kokugweba okukhulu okanye ingqiqo, nakule nguqulo "yentsimbi" yokunqunyanyiswa incediswe malunga ne-200 kg ngaphandle kokuba kufuneka ijongane ne-440i xDrive, eyenza i-asi yangaphambili ibe lula kwiimpendulo.
I-Motricity yenye yezona zinto zibalaseleyo, kuba kulo mzekelo sinokungenelela kokwahlukana kwe-self-locking (ukuzikhethela) ngasemva, okuphelisa nasiphi na isilingo sokutyibilika ngelixa sincedisa ukubeka amandla emhlabeni.
Sifanele ukunconywa ngokuqhuba, ngakumbi njengoko i-BMW ngoku “ayisacingi” ukuba nevili lokuqhuba elisoloko linzima kuyafana nomdlalo weqonga. "Idatha" echanekileyo isoloko idluliswa malunga nobudlelwane bamavili kwi-asphalt ngaphandle kwempendulo enovalo kakhulu phakathi.
… kunye ne-M440i xDrive
I-M440i xDrive yeyodidi olwahlukileyo, kunye ne-374 hp ihanjiswa yi-in-line six-cylinder injini. Kwaye zikwaxhaswa yi-8 kW/11 hp motor motor, esivumela ukuba siyichaze njenge-mild-hybrid ene-48 V iteknoloji.
UMichael Rath, ojongene nophuhliso lwale injini, eyaqala kwiinyanga ezimbalwa ezidlulileyo kwi-3 Series, ichaza ukuba "i-turbocharger entsha yokungena kabini yamkelwa, ilahleko ye-inertia yancitshiswa ngama-25% kwaye ubushushu bombhobho bonyuka (ukuya kwi-1010º C), zonke ngenjongo yokufumana impendulo engcono kunye nesivuno esiphezulu, kule meko akukho ngaphantsi kwe-47 hp eyongezelelweyo (374 hp ngoku) kunye ne-50 Nm ngaphezulu (500 Nm peak). Kwaye elo yelenqe libhekiselele ekukhawuleziseni okudidayo njenge 4.5 s ukusuka ku-0 ukuya kwi-100 km/h kakuhle bayayibonisa.
Imveliso yombane ayisetyenziswanga kuphela ukuxhasa isantya (esiphawuleka kwisiqalo kunye nesantya siphinde siqale), kodwa “nokugcwalisa” iziphazamiso ezimfutshane kakhulu kunikezelo lwetorque kwiigiya zothumelo oluzenzekelayo oluzii-Eight-speed Steptronic leyo, okokuqala, ifakwe kuzo zonke iinguqulelo zeBMW 4 Series Coupé.
Kukwakho iSteptronic Sport version yothumelo olufanayo, umgangatho kwiinguqulelo ze-M kunye nokuzikhethela kwezinye iimodeli ezahlukeneyo, kunye nempendulo ekhawulezileyo - kwakhona isiphumo somsebenzi omtsha we-Sprint - kunye neepaddles ze-gearshift kwivili lokuqhuba.
Omnye umba othe wagqama kwezi khilomitha kumzila wendlela kukuba iibhuleki zeM Sport eziqinisiweyo - ezine ezigxininisiweyo ezine-piston calipers ngaphambili kwiidiski eziyi-348 mm kunye nekhalipha enye edadayo kwiidiski eziyi-345 mm ngasemva - zimelane “nempatho yokothuka. “Ezithotyiweyo, zingaqapheli iimpawu zokudinwa okuxhaphakileyo kwiinkqubo zokuqhobosha iziqhoboshi xa ziphantsi kwemigudu yobu bunzima.
Kwaye kwakunokwenzeka ukuqaphela isenzo somda ongasemva wokwahlukana (kwe-elektroniki). Ikakhulu kumagophe aqinileyo, apho ukuthambekela kwevili elingaphakathi kwigophe ukutyibilika phantsi kokukhawulezisa kuncitshiswe kakhulu, njengoko i-clutch ivaliwe, ukuhambisa i-torque kwivili elingaphandle ukuya kwigophe kunye nokutyhala imoto ukuya ngaphakathi kwayo, xa imithetho. yefiziksi zama ukukudubula ngaphandle.
Ngale ndlela, i-M440i xDrive (ekwancediswa yi-four-wheel drive) ikwazi ukulahlekelwa yintshukumo encinci, ngelixa uzinzo kunye nokuqikelelwa kweempendulo zixhamla.
