Yaida kwenguva refu, iyo 718 Cayman GT4 RS yave munzira - pamwe nekukasira… -ichishanda sepamusoro pePorsche diki yepakati-injini yekumashure coupe.
Uye kupihwa izvo zvakatowanikwa ne718 Cayman GT4 - kune vazhinji, bhenji - zvinofanirwa kutarisirwa kuti RS ichawedzera kukwidziridza kuita kwayo, kusimba uye aerodynamic kugona.
Sezvaungatarisira, semune 911 inoenderana, iyi RS ichaisa hunyanzvi pamusoro pezvimwe zvese, kuti uwane nguva yakanakisa inogoneka mukurwisa chero dunhu riri panyika.
Chii chokutarisira?
Mune spy-mifananidzo yatinokuunzira iwe seyakasarudzika yenyika, kushamisika kunouya nekuona kwete imwe chete, asi maviri ebvunzo prototypes yeramangwana 718 Cayman GT4 RS, iyo isingangoratidzi mutsauko pakati pe "yakajairika" GT4 nemamwe maCaymans, asi zvakare ratidza kusiyana kwakajeka kune mumwe nemumwe.
Misiyano iri pachena inoreva iyo hombe yeaerodynamic apparatus, inoratidzira bapiro rekumashure - rakakura zvakanyanya - iro rinotsamira pamatanho maviri matsva anotora iyo "gooseneck" fomati yatakatoona mu911 GT3 itsva uye inovawo chikamu che. ramangwana 911 GT3 RS, chete ne XXL zviyero.
Chinhu chinokatyamadza ndechekuti imwe neimwe yebvunzo prototypes ine akasiyana mapapiro ekumashure, ayo anogona kuratidza chimwe chezvinhu zviviri. Pamwe Porsche ichiri kuyedza akasiyana aerodynamic/simba masisitimu eiyo itsva 718 Cayman GT4 RS, kana zvikasadaro tichava neaviri chaiwo GT4 RS zvigadziriso, imwe yacho ingangobatanidzwa mune imwe sarudzo pasuru.
Iyo prototype ine kunyoreswa "LB" inoratidzika kunge yakanyanya kusimba pazviviri izvi, nerupo bapiro rakamiswa pasi pezvitsigiso zviviri zvakatetepa kupfuura imwe prototype (kunyoreswa "BB"), iyo inogona kuratidza zvakasiyana zvinhu mukuumbwa kwayo.
Isu tinoti iyo "LB" ndiyo yakanyanya kurumbira, kunyangwe iine ... inoyevedza bapiro inotsigira, zvakare yekuunza yakakura kumberi muparadzi - inoenderera mberi kumberi - inoita kunge inotora mhepo (yakafukidzwa) kumberi kwefenda (sepa iyo 911 GT3 RS) uye nekuunzawo centre-grip single-nut marimu. Pa "BB", tinoona anozivikanwa mavhiri mashanu-pini eGT4.
Zvakare chakatanhamara pane ese ari maviri kusavapo kwehwindo redivi rechipiri, rakatsiviwa nemhepo yekupinda, isu tinofunga, yemuchadenga matanhatu-cylinder boxer - yakagarwa nhaka kubva ku718 Cayman GT4 uye GTS - asi, zvakare, zvinotora maviri akasiyana madhizaini mu. imwe neimwe prototypes. Izvo zvicharamba zvichionekwa kuti imwe chete yadzo ichashandiswa here kana kuti tichakwanisawo kuwana ese ari maviri. Uye waona here kuti hwindo rekumashure rakazara opaque?
Pakupedzisira, kumashure, zvinokwanisikawo kuona mutsauko pakati pemaprototypes maviri. Kwete chete isu tine ruzivo rwakajeka rwekuti kutetepa kwakadini kwebapiro rebapiro kune "LB" pane pa "BB", asi iyo tailpipes inosiyanawo kubva kune imwe neimwe.
6 cylinder atmospheric boxer
Kukurudzira yakanyanya kusimba ye718 Caymans, isu tichave nechadenga nhanhatu-cylinder yakatarisana neGT4 yatozivikanwa. Mune yekupedzisira, 4.0 l boxer - iyo isina chekuita ne911 GT3's identical-capacity unit - inogadzira 420 hp pa7600 rpm ne420 Nm pakati pe5000 rpm ne6800 rpm.
Nokuda kwe718 Cayman GT4 RS hapana kuwedzera kukuru kwesimba kunotarisirwa, kunyange kuitira kuti motokari itsva yemitambo irege "kutsika" zvitsitsinho zve911 GT3 itsva kana kunyange ramangwana 911 GT3 RS. Runyerekupe rwunonongedza kuhunhu hwakatenderedza 450 hp, asi hapana chiri chokwadi.
Kunyanya chokwadi ndechekuti iyo chete kutapurirana inoshandiswa ndeye manomwe-kumhanya PDK (dual clutch). RS ndeyekugona uye nekumhanyisa muchiuno, uye hapana bhuku rekushandisa munyika rinoshandura magiya nekukurumidza sekutapurirana mbiri-clutch. Kune vateveri vegiya giya bhokisi, iyo GT4 icharamba ichipa.
