Alfa Romeo ya mbere ya Gulia GTA (Ubwoko 105) yatunganijwe na Auto Delta hanyuma yerekanwa ku isi mu 1965 - Giulia GTAm izagaragara nyuma yimyaka ine. Umushinga wakorewe mu mahugurwa ya Balocco no kugerageza (byafunguwe hashize imyaka ine), hejuru yisaha nigice cyamajyepfo yuburengerazuba bwa Milan.
Kandi mubyukuri munsi yinzu imwe mpura na Alfa Romeo Giulia GTA na GTAm guhera mu 2021, imodoka yo gusiganwa ifite uburenganzira (nubushobozi) bwo kujya mumuhanda, izaba ifite umusaruro ugarukira kubice 500 nibiciro bihuye - ibihumbi 215 na 221.000 byama euro muri Porutugali, GTA na GTAm - hamwe nibi bidasanzwe.
Birakwiye kwibuka icyo Giulia yashakaga kuvuga kuri Alfa Romeo. Yagaragaye muri 2016 kugirango azamure imbaraga zimodoka zabataliyani hamwe na formula "moteri yimbere-yinyuma yimbere" yari isanzwe iranga moderi yumwimerere, guhera 1962.
Nibyo, kubera ko atari ukubura “ibiranga umubiri” Alfa Romeo yageze mubihe arimo muri iki gihe (moderi ebyiri gusa no kugurisha buri mwaka ibice 50 000, mugihe muri 80 ya 80 byageze kuri 233.000 byanditswe mumwaka), nubwo kuberako kunanirwa mubucuruzi, bimaze kuba muri iki kinyejana, buri gihe byashimiwe cyane kubishushanyo mbonera.
Ariko kugirango imodoka igende neza ntabwo bihagije kugira isura ireshya, igomba kuba ifite ibiyirimo kandi muribi byombi ubuziranenge rusange hamwe nigitekerezo cyimbere hamwe nubuhanga ntibwari kumenya kugendana nibyiza byagaragaye muri amarushanwa afite ibikoresho byiza, cyane cyane Ikidage.
Ihuriro rya Giorgio yinyuma yimodoka yahaye Giulia hanyuma Stelvio - moderi ebyiri zonyine - gusimbuka kwingirakamaro kurwego rwose.
Alfa Romeo Giulia GTA
GTA, kureshya hamwe nubugizi bwa nabi
Nkibisanzwe, Giulia ireshya ninkinzo yayo ya mpandeshatu ikora nka grille, ikikijwe n'amatara maremare, guhuza ibitsina hafi yubusambanyi hamwe na convex mumashusho yumubiri ninyuma nini, irangwa na C-nkingi.
Kandi, byumvikane ko, muri iyi verisiyo ya GTA ibisubizo byanyuma birashimishije kurushaho, tubikesha kwaguka kwimikorere yumubiri hamwe n "" ibyongeweho "muri fibre ya karubone, nko mubitandukanya munsi ya bamperi yimbere itera cm 4 kandi ikamanuka kugirango itezimbere umutwaro wa aerodynamic: "80 kg imbere kumuvuduko mwinshi", nkuko nabisobanuriwe na Daniel Guzzafame, injeniyeri yiterambere rya GTA.
Birashobora kugaragara ko imodoka ifite imitsi kurenza Quadrifoglio isanzwe "ikora", ikerekana imyirondoro yagutse ya karubone mumbere yimbere (nini, kuzana umwuka mwinshi wa 10% kugirango ukonje moteri), kumpande kuruhande. ibiziga, mubiziga byiziga kugirango ugabanye ubwinshi bwimodoka.
Intego ya "slimming" (nyuma ya byose, GTA igereranya Gran Turismo Alleggerita) nayo yatumye hajyaho amadirishya yinyuma ya polyakarubone hamwe nidirishya ryinyuma (muri GTAm), imbaho zumuryango, ibyuma byihagarika byoroheje hamwe nintebe ziva muri Sabelt no muri fibre ya karubone. .
Abafatanyabikorwa hamwe na gen
Diffuser yinyuma irimbishijwe imitwe ibiri ya titanium hagati ya tailpipes ifite umukono ukomeye wa Akrapovič, kandi ibaba ryinyuma nini ni fibre ya karubone kandi irashobora gusunika GTA mubutaka hamwe na kg 80 zipakurura indege.
Ibikoresho byinshi bya pneumatike ni Michelin Pilot Igikombe 2, gifite ibice bibiri bitandukanye bya reberi, byumva "murugo" munzira kimwe no kuri asfalt rusange - niyo mpamvu igura amayero 500 buri… -, ibiziga bikozwe ya 20 ″ no kuba duhura nuruhererekane rukora-rukora sedan hamwe nimbuto imwe ya bolt ifasha kurema neza ko duhura n "inyamaswa" ukireba.
Na feri ya karubone-ceramic - iyo kuri Quadrifoglio idahitamo kugiciro cyamayero 8.500 - gusa ibi ubyemeze, nkuko umukono wa Sauber Engineering ubikora, kumpande zombi iruhande rwiziga ryinyuma, byerekana uburambe bwikigo mumyaka 50 yimodoka yo mubusuwisi gusiganwa (kimwe cya kabiri muri Formula 1) yakoreshejwe mugutezimbere GTA, ndetse nintererano itaziguye yatanzwe nabashoferi ba Alfa Romeo Antonio Giovanazzi na Kimi Raikkonen.
Gourmet suede kugeza itagaragara
Ibidukikije bimwe byo gusiganwa biranga imbere muri verisiyo zombi, ariko ndetse na "ikinamico" muri GTAm, idasaba intebe yinyuma (mu mwanya wabyo hari intebe itwikiriwe na Alcantara yingofero ebyiri ndetse no kuzimya umuriro) akanateranya ingoma zo guhatanira, hamwe na fibre fibre fibre, nayo itwikiriye muburyo bumwe bwa "gourmet suede" na Alcantara (kugirango ibuze imibiri yabayituye kunyerera hamwe nuburemere bwa "g") hamwe nibikoresho bitandatu bifatanye.
Ikibaho kirasa muribintu byombi, bitwikiriye igice cya Alcantara kugirango wirinde kugaragariza ibintu byinshi biturutse ku mucyo, ukareba ibara ryamabara yo hanze yumubiri (ibyo, keretse umukiriya abisabye, bishobora kugira amabara atatu gusa: icyatsi, cyera cyangwa cyangwa umutuku… amabara y'ibendera ry'Ubutaliyani). Ariko intego yo gukurikiza verisiyo ya GTAm kumirire irushijeho gukomera (ipima kg 100 ugereranije na Quadrifoglio na 25 kg ugereranije na GTA) ndetse byari bifite ishingiro ryo gusimbuza inzugi z'umuryango imishumi ifite imikorere imwe.
Ibikoresho bifite ubuziranenge buringaniye, nkuko birangira, biruta bimwe mubirango rusange, birutwa nibihembo bimwe na bimwe, ariko ecran ya infotainment ni nto kandi sisitemu yo kugendana burigihe isa nkintambwe imwe inyuma yibyo igomba kuba (mubihe mubihe aho ntituzi neza umuhanda turimo, bituma habaho itandukaniro riri hagati yo gukurikira inzira wifuza no kuzimira, nkuko byari bimeze…).
Ikwirakwizwa ryemeza byinshi
Intebe zirimo kugenzura amajwi, ikindi kizunguruka cyo guhitamo uburyo bwo gutwara ndetse nini nini yo kugenzura infotainment, wongeyeho, birumvikana ko kuri ZF yihuta ya moteri yihuta ya moteri hamwe na torque ihinduranya, hamwe nintoki zinyuramo (“gukuramo” hejuru na “Ongeraho” hasi ”).
Hakozwe kalibrasi yihariye kugirango ikoreshwe, kugirango ishobore gukuramo amafaranga moteri igomba gutanga kandi ifite umuvuduko mwinshi, ushobora kuba munsi yibihumbi 150 byamasegonda mugihe hatoranijwe uburyo bwo gutwara ibinyabiziga. Iyo muri ubu buryo, reaction yinyuma yinyuma itandukanye hamwe no gukomera kwihagarikwa biteguye "intambara", wongeyeho uburyo bwo kugenzura ituze kugeza igihe iterabwoba ryo kubura ribyutsa ibitotsi byinshi.
Gukoresha ibikoresho bikozwe neza kurushaho hamwe na podiyumu nini ya aluminiyumu yoroheje (aluminium) yashyizwe ku nkingi, nubwo idahuye n'ubwiza bwo kohereza Porsche PDK.
Kangura V6
Gusana bimwe mubice byimbere bifata kwinangira iyo mbyutse moteri hamwe na pulse nkeya ya buto yo gutwika. Urusaku ruvuyeho rusa nkaho rwerekana ko habaye amasaha make yo gusinzira, mugihe kimwe kigaragaza impano "hasi", ndetse no kwibasirwa kenshi na flegm (muburyo bwo gutwara siporo), uhereye kumarita nyamukuru yo guhamagara GTA: Cyangwa iyo moteri itari yarakozwe nabashakashatsi "ku nguzanyo" ya Ferrari.
Umwe muri bo, Leonardo Guinci, injeniyeri ya moteri ya Alfa Romeo, igihe isi yatangizaga Stelvio Quadrifoglio (ikoresha moteri imwe) yemeye ko “guteranya amashyanyarazi hagati ya V ya banki ya silinderi biri gukorwa yize, ibyo bikaba byemerera umwanya ndetse nigisubizo cyihuse ", nkuko bisanzwe mubisobanuro byubudage.
Guinci yansobanuriye kandi ko iyi V6 mubyukuri ituruka kuri "gluing" ya moteri ebyiri-eshatu, buri kimwe na turbo yacyo (ntoya, inertia nkeya, kugirango wirinde gutinda gusubiza) nibindi bice byihariye, mubice bibiri. Ikoranabuhanga rya arsenal yiyi V6 iragaragazwa kandi na sisitemu yo gukuraho imwe mu ntebe ya silinderi ku mizigo yihuta kandi nta mushoferi utabasha kuyibona, ibyiyumvo cyangwa amajwi (ndetse n'amatwi “yumubiri”).
Mubikorwa, ntibishobora kuvugwa ko ibyo kurya bitagabanije cyane, kuko nubwo nta gukabya gukabije narangije gufata inzira yikizamini kumihanda nyabagendwa igera kuri 20 l / 100 ...
Abadage bahanganye
Ariko urupapuro rwa tekiniki rwa 2.9 V6 (rufite inkoni nshya zihuza, wongeyeho indege ebyiri zamavuta yo gusiga hamwe na mapping nshya), byose muri aluminium, birashimishije rwose kandi niba Quadrifoglio yamaze kunganya ibyiza byakozwe ninganda zubudage hamwe na 510 hp (soma amarushanwa ya Mercedes-AMG C 63 S na BMW M3), ubu abasha guhaguruka no gufata ikibanza (cyagenewe imodoka ikomeye cyane mwishuri) wenyine, hamwe na hp 540 (yihariye imbaraga za 187 hp / l) na 600 Nm (muriki gihe yakubiswe na BMW na 650 Nm ihwanye na C 63 na Audi RS 5).
Niba kandi imbaraga zisumba izindi twongeyeho misa yo hasi (1580 kg muri GTAm, kg 25 munsi ya GTA, no kurwanya kg 1695 ya Giulia Quadrifoglio, 1755 kg ya C 63 S, 1805 kg ya M3. hamwe na 1817 kg ya RS 5) rero dukwiye kwitegura gukora ballistique numwana mushya kuri blok.
Ariko hano haribintu bitengushye, ndetse urebye ko turi kurwego rwa stratosfera, kuko 300 km / h yumuvuduko wo hejuru uri munsi ya 307 km / h ya Giulia Quadrifoglio (ntanumwe murimwe ufite igikoresho cya elegitoroniki cya Abadage bahanganye, basaba agaciro kinyongera kurekurwa) hamwe no kwiruka bitagabanije kugera kuri 100 km / h bibera muri 0.2s munsi ya M3, muri RS 5 cyangwa Giulia Quadrifoglio no muri 0.3s munsi ya C 63 S.
Kandi, ugereranije na Giulia Quadrifoglio, GTAm natwaye yungutse gusa icya cumi cya kilometero yo gutangira (21.1s vs 21.5s) hamwe na kimwe cya kane cya 0 kugeza 200 km / h (11.9s vs 12.3s). Ntibiteganijwe. Gusa mugusubirana 80-200 km / h (8.6s na 9.3s) itandukaniro riragaragara.
Ku ruziga
Hariho uburyo bune bwo gutwara bushobora gutoranywa ukoresheje ADN ya ADN: Dynamic, Natural and Advanced Efficiency (nkuko biri muri moderi zose za Giulia) na Race, yihariye verisiyo ikaze, ibuza sisitemu yo kugenzura ituze rwose, ikintu kibereye gusa abapilote barangije, kuko mubyukuri byihuta cyane umurongo uwo ari wo wose ni urwitwazo kugirango impera yinyuma irekure, nkumurizo wimbwa mugaragaza umunezero iyo ubonye nyirawo.
Ubushishozi burenze (hafi ya itegeko niba utwaye byihuse kumuhanda "ufunguye"), noneho, ni ugukora uburyo bwa Dynamic, butuma ubufasha bwa elegitoronike muburyo bwa "bwitegereza" mugihe cyoroshye kandi bukagira ibikorwa bihuriweho na sisitemu ya vectoring ya torque hamwe ninyuma (mehaniki) yo kwifungisha kugirango yemere "drifts" igenzurwa mu mfuruka, ariko hamwe nukuri kurwego rwo kumenya neza ko birangira neza.
Mu birometero bikozwe mumihanda yo mumisozi, ntabwo buri gihe bisanzwe, byashobokaga kubona ko guhagarikwa bishoboye kwemeza urwego rwiza cyane rwo guhumurizwa, ibi bikaba arimwe mubitangaje bitangaje bya Giulia GTA na Giulia GTAm.
Kuri chassis, inzira zaraguwe (cm 5 inyuma na cm 2,5 imbere) kubera ko ibisabwa kugirango uhagarike inyuma (axe yigenga y'amaboko yigenga) ni byiza cyane kuko kuyobora (2.2 guhinduranya uruziga kuva hejuru kugeza hejuru hejuru) birihuta cyane kandi neza kandi kubera ko umutambiko w'imbere ubwawo (hamwe na mpandeshatu zirenga) zifite uburyo bwo kubaga iyo bwinjiye mu mfuruka.
Nibisubizo bya aerodinamike ikora - ibintu byimukanwa bimaze kuvugwa muri fibre ya karubone mugice cyo hepfo ya bamperi - bigenzurwa nubuyobozi bwa elegitoronike bwa sisitemu ya CDC (Chassis Domain Control) nayo igenzura ikwirakwizwa rya torque niziga ryiziga umutambiko winyuma cyangwa impinduka zihindagurika.
Umutwaro mwiza wa aerodynamic kumurongo
Kubera iyo mpamvu, ibaba ryinyuma (hamwe nintoki enye zishobora guhindurwa) ryihariye rya Giulia GTAm ningirakamaro cyane. Feri ifite disiki ya ceramic yahoraga idacogora kandi ifite ubushake nimbaraga zo "kuruma" umuntu wese yatangajwe.
Ibaba ry'inyuma rirashobora guhinduka ...
Niba Giulia GTAm idacukuye icyuho kijyanye na Quadrifoglio muburyo bwo kubara, bizashoboka kubikora mugusuzuma ubuziranenge? Igisubizo ni yego: ikintu cyose gisunika imodoka hasi (kugeza inshuro eshatu umutwaro wa aerodinamike ya Quadrifoglio) ufasha guhinduka neza / umutekano ndetse bikanasobanurwa mubyiza mukurwanya chronometer, cyane kuruta kumurongo ugororotse. ibipimo.
GTAm yunguka 4.07s kuri lap (kuva 5.7 km) hano kuri Balocco, 4.7s kuri Nardo (km 12,5 kuri lap, ariko kuba umuzenguruko idafite aho ifata kugirango ifashe aerodinamike ikora itandukaniro) na 2.95 muri Vallelunga, burigihe kurwanya Giulia Quadrifoglio (mubihe byanyuma hariho amakuru ya telemetrie yemeza ko umuvuduko wo kunyura mu mfuruka yihuse ukorwa mu nkunga ikomeye igera ku itandukaniro rya 6 km / h, ku ruhande rwa GTAm, mu gihe muri zone nyinshi zikomeye Quadrifoglio ari , kuri byinshi, 2 km / h gahoro).
