La marhe ayengalunganga. I-Porsche 718 Cayman GT4 RS entsha ayisebenzisi, njengoko kulindelekile, inguqulo ye-boxer ye-silinda emithandathu ye-718 Cayman GT4 enamandla ngakumbi.
Okumangalisayo kukuba, i-Porsche yathatha imbethi manqindi eyi-cylinder enqwenelekayo ngokwemvelo ukusuka kwi-911 GT3 kunye ne-911 GT3 Cup (nangona zombini ziyi-4.0 iilitha zomthamo, ziziinjini ezihlukeneyo) kwaye zibeke kwi-injini ye-injini ye-718 Cayman engapheliyo.
Isigqibo esihle esingalindelekanga, kunye ne-500 hp yamandla ekhangisayo; indlela ngaphezu 450-480 hp ukuba uninzi amarhe wachaza kwaye kuphela 10 hp ngaphantsi kwe 911 GT3. Zange ngaphambili iPorsche izise i-718 Cayman kufutshane ne-iconic 911 yayo.
Ikwangqinelwa ngokuyinxenye ii-23.6s ngaphantsi kwe-718 Cayman GT4 RS ezuzwe eNürburgring xa kuthelekiswa ne-718 Cayman GT4. Ngaphezulu kwe-80 hp yamandla, akumangalisi ukuba wakwazi ukufumana ngaphezu kwesibini ngekhilomitha nganye, kunye nexesha lokugqibela le-cannon ye-7min09.3s (20.832 km).
Nge-500 hp kunye ne-450 Nm (20 Nm ngaphezulu kwe-GT4), ukusetyenziswa ngokukodwa kwe-gearbox ye-PDK ekhawulezayo ezisixhenxe kunye nobunzima obuqulathwe ngakumbi - nge-1415 kg (DIN), i-GT4 RS ilula nge-35 kg kune-GT4. - qinisekisa inkwenkwezi entsha yePorsche inzuzo enentlonipho.

Musa ukuhlala ngasenjinini
Ukusetyenziswa kwe-injini ye-911 GT3 inokuba yinto eyothusayo enkulu kwesi sityhilelo sokuqala se-718 Cayman GT4 RS, kodwa ekuguqukeni kwayo ukusuka kwi-GT4 ukuya kwi-GT4 RS, akukho nto ishiyekileyo.
Ukuqala ngendlela umoya ofikelela ngayo kwi-injini, apho iifestile ezincinci ezingasemva zezinye iiCaymans zithe shwaka ukuze zenze indawo yokungena komoya kwi-GT4 RS. Abagcini nje ukuphucula ukuhamba komoya, baphucula isandi sokungena kwe-flat-six, esondele kakhulu kwiindlebe zabahlali.
"Isixhobo" esitsha esivela kwi-Porsche kwakhona siza nephakheji entsha, egqithise kakhulu ye-aerodynamic, igxininisa iphiko elitsha elingasemva "intamo ye-swan", njengoko sibonile kwi-911 GT3.
Xa idityaniswe ne-30mm engaphantsi kwemvume yomhlaba engaphantsi kwe-718 Cayman, umoya we-airguards phezu kodaka lwangaphambili, i-aerodynamically optimized ezantsi edityaniswe ne-diffuser yangasemva, i-diffuser yangaphambili ehlengahlengiswayo kunye ne-spoiler yangaphambili ene-Side "blades", iyakwazi yokuvelisa i-25% yokunciphisa amandla (inkxaso engalunganga) kwimowudi yoMsebenzi (ecetyiswayo kwiisekethe) kune-718 Cayman GT4.

Ukugcina ubunzima kumaxabiso alawulwayo, iPorsche yenza ukusetyenziswa kwepolymer eyongeziweyo yekhabhoni (CFRP) - ihood yangaphambili kunye nefender -, isikwe kwizinto ezifunxa isandi, isebenzise iglasi ekhaphukhaphu kwifestile yangasemva, izibambo zangaphakathi. ngoku ziieribhoni zelaphu, iindawo zokugcina ngoku zinemingxuma, kwaye neemethi ezisetyenzisiweyo zikhaphukhaphu.
Okokugqibela kodwa kuncinci, i-chassis nayo yalungiswa. Oku ngoku kudityaniswe nomsebenzi womzimba kunye namalungu ebhola, ukwandisa, utsho uPorsche, ngakumbi ukuchaneka kunye nokuphendula kokuziphatha kwe-718 Cayman GT4 RS. Ukumiswa - i-shock absorbers kunye nemithombo - iza nohlengahlengiso oluthile, njengoko kwenza imivalo yokuzinzisa.
Iphakheji ye-Weissach
Ngokuzikhethela, iphakheji ye-Weissach yongeza ukugqiba kwe-carbon fiber textured kwiphiko elingasemva, indawo yangaphambili, ukungena komoya okuphindaphindiweyo, isivalo sebhokisi yomoya kunye nezibuko.
I-titanium exhausts ifana neye-Porsche 935 ekhethekileyo kwaye i-titanium nayo iyinto ekhethiweyo kwi-roll cage. Ideshibhodi igutyungelwe kwiRace-Tex kwaye ifestile yangasemva ibandakanya uphawu olukhulu lwePorsche.
