I-Six-cylinder boxer, i-natural aspirated, six-speed manual gearbox. Awudingi ukusho lutho ukuze uzinikele kwabasha I-Porsche 718 Cayman GT4 futhi 718 Spyder.
Ipheya entsha yezimoto zezemidlalo ezisuka e-Stuttgart ayikaze ibe namandla futhi ishesha kangaka, futhi ayikaze yabelane kangaka phakathi kwayo - oomakhenikha no-chassis - njengoba benza manje.
Injini ayifani ne-911 GT3
Okugqamile, vele, kusenjinini futhi - ukumangala - naphezu kokuba i-boxer-cylinder eyi-six cylinder ngokwemvelo ilangazelela amandla angu-4.0 l, akuyona injini ye-911 GT3, njengoba amahemuhemu ekhonjisiwe. Iyunithi entsha engu-100%, ephuma emndenini ofanayo wenjini njenge-911 Carrera, hhayi umndeni wenjini osetshenziswe ku-911 GT ne-Cup.
Nokho, izinombolo azijabhisi. Ishaja entsha ye-718 Cayman GT4 kanye ne-718 Spyder I-420 hp ku-7600 rpm kanye ne-420 Nm phakathi kuka-5000 rpm no-6800 rpm , ukukhuphuka okungu-35 hp no-45 hp, ngokulandelana, uma kuqhathaniswa nabangaphambili i-Cayman GT4 ne-Boxster Spyder.
Bhalisela iphephandaba lethu
I-4.0 boxer six-cylinder entsha inomkhawulo kuphela ku-8000 rpm, futhi nakuba igqama ngokuzwakala kwayo, ukuhleleka kokulethwa nokuphendula ngokushesha, ayikhohlwanga ngokusebenza kahle, noma amazinga okukhipha umoya - isihlungi se-particle sikhona, futhi ngomthwalo oyingxenye, "ingavala" enye yamabhange angama-cylinder.
Ngomjovo oqondile, iphinde ibe injini yokuqala ekwazi ukwenza ama-rev aphezulu isebenzisa ama-injection e-piezo, i-crankcase iwuhlobo olomile, futhi inohlelo oluguquguqukayo lokuthatha.
Uma kuhlangene nomshayisibhakela kukhona u-gearbox oshintshwayo onamagiya ayisithupha oshintshwayo, okwazi ukuphonsa u-1420 kg (DIN) ukusuka ku-718 ukuya ku-718. iye ku-100 km/h ku-4.4s nje kuphela, ifike ku-160 km/h ku-9.0s ifike ku-200 km/h ku-13.8s. . Zihlukene ngejubane eliphezulu kuphela, kanti i-718 Cayman GT4 ifinyelela ku-304 km/h kanye ne-718 Spyder efinyelela ku-301 km/h.
Ukunciphisa okwengeziwe ngaphandle kokuthinta ukudonsa
I-aerodynamics ebuyekeziwe ye-718 Cayman GT4 iyivumele ukuthi ikhulise kakhulu ukusebenza kahle kwayo ngokufeza khuphula inani lokwehla ngo-50% , ngaphandle, nokho, ukudonsa okulimazayo - ukudonsa kwe-aerodynamic.
Okufaka isandla kulokhu kusebenza kahle kwe-aerodynamic okuphakeme yi-diffuser entsha yangemuva - iyodwa ibala cishe u-30% yenani eliphelele le-downforce - kanye nephiko elisha elingemuva elikhiqiza u-20% we-downforce ngaphezulu kwangaphambi kwayo - 12 kg eyengeziwe ku-200 km / h -; ngaphambili, okufaka isandla ebhalansi ye-aerodynamic, sibona i-spoiler esisha nesikhudlwana kanye nokuba khona “kwamakhethini omoya” noma amakhethini omoya, athuthukisa ukugeleza komoya okudlula amasondo angaphambili.
I-718 Spyder ihlukaniswa ngokungabi bikho kophiko lwangemuva lwe-coupe, kodwa inophiko oluhlehlayo olusuka ku-120 km/h — nokho, iyiSpyder yokuqala ekwazi ukukhiqiza amandla aphansi ku-axle yangemuva.
isilungele izifunda
Ngokokuqala ngqa, i-718 Spyder izuza ku-chassis efanayo ne-718 Cayman GT4 - nokuthi iyiphi i-chassis...
Ukusetshenziswa kwamajoyinti ebhola kuwo womabili ama-ekseli kunikeza ukuxhumana okuqinile nokuqondile phakathi kwe-chassis nomzimba, okwandisa ukunemba okuguquguqukayo. Okujwayelekile kufakwe i-PASM (Porsche Active Suspension Management), imvume yomhlaba yehliswa ngo-30 mm, futhi iza ne-PTV (Porsche Torque Vectoring), noma i-torque vectoring, enomehluko wokukhiya ngomshini.
Ukumisa izimoto zezemidlalo, zifika zifakwe ama-disc anezimbobo nangena umoya angu-380 mm ububanzi, nama-monobloc aluminium caliper anamapiston ayisithupha ngaphambili namaphistoni amane ngemuva.
Labo abafuna ukusebenza okwengeziwe ohlelweni lokubhuleka bangakhetha amadiski e-carbon-ceramic (PCCB), asemakhulu - 410 mm ngaphambili no-390 mm ngemuva - kodwa alula cishe ngo-50% uma kuqhathaniswa nensimbi.
Zombili futhi zifakwe amathayi asebenza kahle kakhulu ePorsche — 245/35 ZR 20 ku-8.5 J x 20 ngaphambili futhi 295/30 ZR 20 ngo-11 J x 20 ngemuva — futhi ekugcineni, konke lokhu, kube amandla engeziwe, i-aerodynamics esebenza kahle kakhudlwana, noma i-chassis enekhono, umphumela wesikhathi esingaphezu kuka-10″ esisheshayo "esihogweni esiluhlaza" se-718 Cayman GT4 okuhlobene nokwandulelayo.
Ukuze uthole ukucija okwengeziwe kwethrekhi, i-718 Cayman GT4 inikeza i-Clubsport Package njengenketho engeza ikheji (ependwe emnyama futhi eboshelwe ku-bodywork ngemuva kwezihlalo zangaphambili), ibhande lomshayeli elinamaphuzu ayisithupha - elinezinhlobo ezimbili zesihlalo. amabhande ehlombe, elinye lawo elihambisana nesistimu ye-HANS - isicishamlilo, ukufakwa kwangaphambili kwe-Lap Trigger (ilinganisa izikhathi ze-lap).
Ufika nini?
Sebevele befikile, noma kungcono, bayatholakala ukuze ba-odwe. Amanani entengo ye-Porsche 718 Cayman GT4 aqala ku-135 730 euros futhi e-718 Spyder aqala ku-132 778 euros.
