Zakale anafuna, ndi 718 Cayman GT4 RS yatsala pang'ono kufika—mwinamwake mwachangu…—ikugwira ntchito ngati pachimake pa kagulu kakang'ono kwambiri ka injini yapakati ya Porsche.
Ndipo kupatsidwa zomwe zakwaniritsidwa kale ndi 718 Cayman GT4 - kwa ambiri, benchmark - ziyenera kuyembekezera kuti RS ikwezanso magwiridwe ake, mphamvu zake komanso zamlengalenga.
Monga momwe mungayembekezere, monga mu 911 yofananira, RS iyi idzayika bwino kuposa china chilichonse, kuti mupeze nthawi yabwino kwambiri pakuwukira dera lililonse padziko lapansi.
Zoyenera kuyembekezera?
Muzithunzithunzi za akazitape zomwe tikubweretserani ngati dziko lokhalokha, zodabwitsazi zimabwera chifukwa chosawona chimodzi, koma ma prototypes awiri amtsogolo 718 Cayman GT4 RS, omwe samangowonetsa kusiyana pakati pa GT4 "yabwinobwino" ndi ma Caymans ena, komanso kusonyeza kusiyana momveka kwa wina ndi mzake.
Kusiyana kodziwikiratu kumatanthawuza zida zazikulu zakuthambo, zomwe zikuwonetsa mapiko akumbuyo - okulirapo - omwe akhazikika pamitundu iwiri yatsopano yomwe imatenga mtundu wa "gooseneck" womwe tawona kale mu 911 GT3 yatsopano komanso yomwe idzakhalanso gawo la mtsogolo 911 GT3 RS, yokhala ndi miyeso ya XXL yokha.
Chochititsa chidwi ndi chakuti ma prototypes onse oyesa ali ndi mapiko osiyanasiyana akumbuyo, omwe angasonyeze chimodzi mwa zinthu ziwiri. Mwina Porsche ikuyesabe masinthidwe osiyanasiyana a aerodynamic / amphamvu a 718 Cayman GT4 RS, kapena tidzakhala ndi masinthidwe awiri apadera a GT4 RS, amodzi omwe mwina ophatikizidwa mu phukusi losankha.
Chitsanzo chokhala ndi kalembera "LB" chikuwoneka kuti ndichopambana kwambiri pa ziwirizi, ndi mapiko owolowa manja atayimitsidwa pansi pa zothandizira ziwiri zomwe ndizochepa kwambiri kusiyana ndi zina (kulembetsa "BB"), zomwe zingasonyeze zipangizo zosiyanasiyana zomwe zimapangidwira.
Tikunena kuti "LB" ndiyomwe imakhala yopambana kwambiri, ngakhale ili ndi ... 911 GT3 RS) komanso pobweretsa ma rimu a nati amodzi. Pa "BB", tikuwona mawilo odziwika bwino a pini asanu a GT4.
Chodabwitsanso pa zonsezi ndi kusakhalapo kwa zenera lachiwiri lakumbuyo, lomwe m'malo mwake limalowetsa mpweya, tikuganiza, kwa bokosi lachisanu ndi chimodzi lamlengalenga - lochokera ku 718 Cayman GT4 ndi GTS - koma, kachiwiri, zimatengera mapangidwe awiri osiyana mu aliyense wa prototypes. Zikuwonekeratu ngati imodzi yokha ndiyo idzagwiritsidwe ntchito kapena ngati tidzakhalanso ndi mwayi wopeza zonsezo. Ndipo kodi mwawona kuti zenera lakumbuyo ndi losawoneka bwino?
Pomaliza, kumbuyo, ndizothekanso kuwona kusiyana pakati pa ma prototypes awiriwa. Sikuti timangodziwa bwino momwe mapiko akumbuyo amawonda kwambiri pa "LB" kusiyana ndi "BB", koma mapiko a mchira amasiyananso wina ndi mzake.
6 cylinder atmospheric boxer
Kulimbikitsa kwambiri ma 718 Caymans, tidzakhala ndi ma silinda asanu ndi limodzi amlengalenga moyang'anizana ndi GT4 omwe amadziwika kale. Pomalizira pake, 4.0 l boxer - yomwe ilibe chochita ndi 911 GT3's identical-capacity unit - imapanga 420 hp pa 7600 rpm ndi 420 Nm pakati pa 5000 rpm ndi 6800 rpm.
Kwa 718 Cayman GT4 RS palibe kuwonjezeka kwakukulu kwa mphamvu kumayembekezeredwa, ngakhale kuti galimoto yatsopano yamasewera "saponda" zidendene za 911 GT3 yatsopano kapena tsogolo la 911 GT3 RS. Mphekesera zimaloza kuzinthu zozungulira 450 hp, koma palibe chotsimikizika.
Chotsimikizika kwambiri ndichakuti njira yokhayo yolumikizira yomwe imagwiritsidwa ntchito ndi ma PDK othamanga asanu ndi awiri (dual clutch). RS ndi za dzuwa ndi liwiro mu kuzungulira, ndipo palibe Buku padziko lapansi kuti kusintha magiya mofulumira ngati wapawiri zowalamulira kufala. Kwa mafani a gearbox yamanja, GT4 ipitiliza kupereka.
