"Sitinangoyika chivundikiro chosiyana pa 3 Series ndikusintha manambala," akufotokoza Peter Langen, wotsogolera wa BMW 3/4 Series, asanamalize lingaliro la zomwe akufuna kwatsopano. BMW 4 Series : "tikufuna kuti ikhale scalpel yathu, ndiko kuti, mawonekedwe a zitseko ziwiri kuti akhale akuthwa kwambiri, onse stylistic ndi amphamvu".
Ndipo ngati mawu amtunduwu nthawi zambiri amakhala otsatsa kuposa china chilichonse, pakadali pano ndizosavuta kuwona kuti, kwenikweni, sitinawonepo BMW coupé yosiyana kwambiri ndi sedan yomwe imagawana nawo maziko, injini, dashboard. ndi chilichonse.
Tinali kale ndi manifesto ya cholinga ichi ndi Concept 4 (yovumbulutsidwa ku Frankfurt Motor Show yotsiriza) komanso momwe mizere ina inafewetsa, kuwonjezera pa impso ziwiri zomwe zinachepa pang'ono, makamaka popeza galimoto yoyesera inatsutsidwa. chifukwa chokhala wolimba mtima kwambiri.
Koma zimakhala zowonjezereka, monga momwe tikudziwira pa magetsi a i4, koma koposa zonse, impso zoyimirirazi ndizolemekeza zakale chifukwa poyamba zinkawoneka m'mafanizo a nthano - zamakono zamtengo wapatali - monga BMW 328. ndi BMW 3.0 CSi.
Kenako, ma creases akuthwa mu bodywork, waistline kukwera ndi glazed pamwamba kumbuyo kumbuyo, m'munsi ndi yotakata kumbuyo (zotsatira kulimbikitsidwa ndi optics kuti amafika mbali ya thupi), minofu ndi yotalikira kumbuyo nsanamira ndi yaikulu. zenera lakumbuyo pafupifupi limapangitsa kuoneka ngati chitsanzo chodziimira pa 3 Series, chimalimbitsa umunthu wake.
Lembetsani ku kalata yathu yamakalata
Ngati m'badwo wakale tidayamba kuwona kulekanitsidwa kwa coupé ndi sedan, ngakhale ndi mayina osiyanasiyana (3 ndi 4), tsopano zonse zimamveka bwino ndi masitaelo osankhidwa omwe angasangalatse ogula omwe angagulitse matupi awiriwo. zambiri.
zambiri zolumikizidwa ndi msewu
Kutalika kunawonjezeka ndi masentimita 13 (mpaka 4.76 m), m'lifupi ndi 2.7 cm (mpaka 1.852 m) ndi wheelbase anatambasula 4.11 cm (mpaka 2.851 m). Kutalika kunali ndi kuwonjezereka kotsalira kwa 6mm chabe pa kulowetsedwa kwake (mpaka 1.383m), kupanga galimotoyo 5.7cm yayifupi kuposa Series 3. Nyimbo zawonjezeka poyerekeza ndi m'badwo wakale - 2.8cm kutsogolo ndi 1.8 cm kumbuyo - yomwe ikadali 2.3 cm mulifupi kuposa Series 3.
Kumbali ina, mawilo akutsogolo tsopano ali ndi camber zoipa kwambiri ndi ndodo zomangira zinawonjezedwa pa chitsulo cham'mbuyo kuonjezera "m'deralo" torsional rigidity, monga Langen amakonda kuzitcha izo, ndi absorbers mantha tsopano ndi yeniyeni hydraulic dongosolo, monga ngati. mu Series 3.
Kutsogolo, chotsitsa chilichonse chimakhala ndi choyimitsa cha hydraulic pamwamba chomwe chimawonjezera kukana pa rebound, ndipo kumbuyo pisitoni yachiwiri yamkati imapanga mphamvu yopondereza yochulukirapo. "Umo ndi momwe galimotoyo imasungidwira kukhala yokhazikika", imatsimikizira mbuye wa mphamvu Albert Maier, yemwenso ndi chinthu chofunika kwambiri pakukula kwatsopano kwa BMW 4 Series.
Kusintha kumeneku kunatsagana ndi matanthauzo atsopano a mapulogalamu, kuwongolera ndi ndalama zenizeni ndi njira zoyendetsera galimoto zomwe zimapereka mwayi wochuluka kwa omwe amayendetsa galimoto, ngati ndizo zomwe akufuna: "galimoto iyenera kulola dalaivala kukhala wabwino monga momwe akuganizira." , akumwetulira Langen, kenako akutsimikizira kuti "mngelo womuyang'anira akadali pamwamba apo, akuwuluka pang'ono".
Nyali zapamutu za LED ndizokhazikika, pomwe nyali zosinthika za LED zokhala ndi laser zimapezeka ngati njira, zotsatizana ndi nyali zopindika ndi magwiridwe antchito angodya okhala ndi kuyatsa kosinthika kwamisewu kokometsedwa pakuyendetsa m'mizinda ndi misewu yayikulu. Pa liwiro loposa 60 km/h, BMW Laserlight imakulitsa nyali zingapo mpaka 550 m, kutsatira njira yamsewu mwachangu.
pampando woyendetsa
Kulowa m'nyumba kumanzere kumanzere kumatanthauza kuzunguliridwa ndi zowonera zama digito monga ma BMW onse atsopano, koma omwe angofika kumene mumtundu uwu, womwe wadutsa kale zaka makumi anayi za moyo ndi mayunitsi olembetsedwa 15 miliyoni padziko lonse lapansi. uwu msika waku China uli kale waukulu kwambiri padziko lonse lapansi).
Kuphatikizana kwabwino kwambiri kwa zida ndi chophimba chapakati kumakondweretsa (muzochitika zonsezi zimatha kukhala ndi kukula kosiyana, kukhala digito kwathunthu ndi kusinthika). The center console tsopano ikuphatikiza batani loyatsira injini, pambali pa iDrive controller, ma switch modes ndi batani la mabuleki oimika magalimoto (tsopano magetsi).
Ndizofulumira komanso zosavuta kufika pamalo abwino oyendetsa ndipo ngakhale madalaivala aatali samamva kukhala oponderezedwa: m'malo mwake, chilichonse chakonzeka kuperekedwa kuti athe kukwaniritsa ntchito yawo yofunika. Zipangizo ndi mtundu wa kuphatikiza ndi zomaliza ndi zamulingo wabwino, monga tikudziwira mu Series 3.
Injini zatsopano za BMW 4 Series
Mitundu yatsopano ya BMW 4 Series imapangidwa motere:
- 420i - 2.0 L, masilinda 4, 184 hp ndi 300 Nm
- 430i - 2.0 L, masilindala 4, 258 hp ndi 400 Nm
- 440i xDrive - 3.0 l, masilinda 6, 374 hp ndi 500 Nm
- 420d/420d xDrive — 2.0 l, masilinda 4, 190 hp ndi 400 Nm mu mtundu wa xDrive (4×4)
- 430d xDrive — 3.0 l, 6 masilindala, 286 hp ndi 650 Nm (2021)
- M440d xDrive — 3.0 l, 6 masilindala, 340 hp ndi 700 Nm) (2021)
Pamaulamuliro a 430i…
Yoyamba mwa injini zomwe tapatsidwa "kulawa" ndi injini ya 258 hp 2.0 yomwe imagwiritsa ntchito 430i, ngakhale kuti sitinazolowere maganizo kuti "30" imagwiritsa ntchito chipika cha masilinda anayi okha.
Nditamaliza mayeso amphamvu pa Arctic Circle (Sweden), pa Miramas track (kumpoto kwa Marseille) komanso, ku Nürburgring, komwe akatswiri opanga ma chassis amakonda kupanga "mayeso asanu ndi anayi", tinapatsidwa mwayi woyendetsa BMW 4 Series yatsopano.
Malo osankhidwa anali pamayendedwe oyesera a mtunduwo ndipo akadali ... ndi thupi lobisika, popeza pambuyo pake zithunzi zovomerezeka zagalimotoyo "zamaliseche", zomwe tikukuwonetsani tsopano zidzawululidwa.
Koma ndi mtundu wokhutiritsa, kunena pang'ono: simumamva kuti injiniyo ilibe "moyo", mosiyana, ndipo ntchito yochitidwa pa ma acoustics imatha kubisala kutayika kwa ma silinda awiri, popanda kukokomeza ma frequency a digito otumizidwa ndi audio ya system, yowonekera kwambiri pamagalimoto oyendetsa masewera.
Ngakhale zili choncho komwe 430i iyi imawonekera kwambiri ndikutha kumeza ma curves. ngakhale titaya mwa iwo popanda chiweruzo chachikulu kapena nzeru, ngakhale Baibulo ili ndi "zitsulo" kuyimitsidwa anathandizidwa ndi pafupifupi 200 makilogalamu pokhapokha ayenera kukumana ndi 440i xDrive, amene amapangitsa kutsogolo chitsulo chogwira ntchito kwambiri agile mu zochita .
Motricity ndi chimodzi mwazinthu zazikuluzikulu, komanso chifukwa pamenepa tili ndi kulowererapo kwa kusiyana kodzitsekera (zosankha) kumbuyo, zomwe zimathetsa chiyeso chilichonse chozembera pamene kuthandizira kuyika mphamvu pansi.
Kutamandidwa koyenera chifukwa cha chiwongolerocho, makamaka ngati BMW tsopano "sakuganizanso" kuti kukhala ndi chiwongolero cholemera nthawi zonse ndikofanana ndi mawonekedwe amasewera. "Deta" yolondola imaperekedwa nthawi zonse ponena za mgwirizano wa mawilo ndi asphalt popanda kuyankha kwamanjenje kwambiri pakatikati.
… ndi M440i xDrive
M440i xDrive ndi yamtundu wina, ndipo 374 hp imaperekedwa ndi injini yapaintaneti ya silinda sikisi. Ndipo amathandizidwanso ndi injini yamagetsi ya 8 kW/11 hp, yomwe imatilola kufotokozera ngati wosakanizidwa wofatsa wokhala ndi ukadaulo wa 48 V.
Michael Rath, yemwe adayambitsa chitukuko cha injini iyi, yomwe idayamba miyezi ingapo yapitayo mu 3 Series, ikufotokoza kuti "turbocharger yatsopano yolowera kawiri idakhazikitsidwa, kutayika kwa inertia kunachepetsedwa ndi 25% ndipo kutentha kwa mpweya kumawonjezeka (mpaka 1010º). C), zonse ndi cholinga chokwaniritsa kuyankha bwino komanso zokolola zambiri, pakadali pano zosachepera 47 hp (374 hp tsopano) ndi 50 Nm zambiri (500 Nm pachimake). Ndipo izi zimapanga chiwembu chakuthamangitsa zosokoneza ngati 4.5s kuchokera 0 mpaka 100 km/h chabwino amawonetsa.
Kutulutsa kwamagetsi kumagwiritsidwa ntchito osati kungothandizira kuthamangitsa (komwe kumawonekera poyambira ndikuyambiranso liwiro), komanso "kudzaza" kusokoneza kwakanthawi kochepa pakutumiza kwa torque mu ma gearshift aukadaulo waukadaulo wa Eight-speed Steptronic womwe, kwa nthawi yoyamba, imayikidwa kumitundu yonse ya BMW 4 Series Coupé.
Palinso mtundu wa Steptronic Sport wotumizira womwewo, wokhazikika pamatembenuzidwe a M ndi zosankha pamitundu ina yamitundu, ndikuyankha mwachangu - komanso zotsatira za ntchito yatsopano ya Sprint - ndi zopalasa za gearshift pachiwongolero.
Chinanso chomwe chidadziwika pamakilomita awa panjanjiyi ndikuti mabuleki olimbikitsidwa a M Sport - ma caliper anayi okhazikika a pistoni kutsogolo kwa ma disc a 348 mm ndi caliper imodzi yoyandama pama diski 345 mm kumbuyo - adapirira "mankhwala owopsa. ” bwino kwambiri.
Ndipo zinali zothekanso kuzindikira zomwe zimachitika kumbuyo kwa limited-slip differential (electronic). Makamaka pa zokhotakhota zolimba, kumene chizolowezi cha mkati gudumu yokhotakhota kuzembera pansi mathamangitsidwe kwambiri yafupika, monga zowalamulira chatsekedwa, channeling makokedwe kwa gudumu kunja pamapindikira ndi kukankhira galimoto mkati mwake, pamene malamulo a physics amayesa kukuwomberani.
Mwa njira iyi, M440i xDrive (yomwe imathandizidwanso ndi magudumu anayi) imatha kutayika pang'ono, pamene kukhazikika ndi kuwonetseratu kwazochitika kumapindula.
