I-Audi RS Q8: Umzala ka-Urus - Ukubuka kuqala

Ngokokuqala ngqa emlandweni weminyaka engama-25 wezinhlobo ze-Audi RS, sidale i-SUV coupé ne-DNA yemoto yezemidlalo yangempela.", Ngala mazwi, u-Oliver Hoffmann, isikhulu esiphezulu se-Audi ISport GmbH yethule uNdunankulu wayo womhlaba, al ILos Angeles Auto Show 2019, i-Audi RS Q8 entsha.

I-V8 4.0 TFSI ene-48-volt hybrid system

V8 4.0 TFSI kusuka ku- i-Audi RS Q8 entsha ithuthukisa i-600 hp. kanye ne-torque engu-800 Nm ebangeni elisuka ku-2.200 kuya ku-4.500 rpm. Ngalesi sikhwama se-supersport, i-Four Rings SUV coupe iyashesha ukusuka ku-0 iye ku-100 km / h ngemizuzwana engu-3,8, okuyimizuzwana engu-13,7 ukufinyelela ku-200 km / h. Ijubane eliphezulu ligcina ngo-elekhthronikhi lifike ku-250 km / h. Futhi, isivinini esingu-305 I-km / h ingafinyelelwa ngesicelo.

Ngenxa yokunikezwa kwamandla amakhulu okugibela i-biturbo engu-48V, i-V8 ihlanganisa ukusebenza okwehlukile nokusebenza kahle okuphezulu. I-starter-generator eqhutshwa ngamabhande (i-RSG) iyinhliziyo yohlelo lwe-Mild Hybrid System (MHEV). Ezigabeni zokwehlisa amandla, kungabuyiselwa kufika ku-12 kW yamandla: la mandla agcinwa kubhethri elikhethekile le-lithium-ion, lapho lithunyelwa khona kamuva kumadivayisi ahlanganiswe kunethiwekhi yebhodi. Uma umshayeli ekhipha isivinini esisheshayo ngesivinini esiphakathi kuka-55 no-160 km / h, i-RS Q8 entsha ingagudla kungathathi hlangothi noma ogwini injini icishiwe kuze kube yimizuzwana engama-40. Ekushayeleni kwansuku zonke, abakwa-Audi bathi ubuchwepheshe be-MHEV bunciphisa ukusetshenziswa kukaphethiloli kuze kufike ku-0,8 wamalitha ngamakhilomitha ayi-100.

Ubuchwepheshe be-COD (Cylinder On Demand) futhi buba negalelo elibonakalayo ekunciphiseni ukusetshenziswa kukaphethiloli, okuvala amasilinda 2,3, 5, 8, 4 kanye no-XNUMX emithwalweni emaphakathi kuya phansi, kuvala umjovo kanye nezigaba zokushisa bese kuvala amaphayiphu okudla nawokuqeda . Lapho kusebenza ngamasilinda we-XNUMX, ukuvumelanisa kwamasilinda asebenzayo kuyalungiswa ngokuya ngephethini entsha yokuhambisa ukuze kutholakale ukusebenza kahle okukhulu, ngenkathi kumagumbi omlilo angasebenzi, ama-piston ahamba ngaphandle kokuchitha amandla. Ngokushesha nje lapho iphedula ye-accelerator icindezeleke ngokuqinile, amasilinda "angasebenzi" ayasebenza futhi.

8-isilinda V emise I-RS Q8 ihlanganiswe no-gearbox ongu-8-speed tiptronic gearbox nge-clutch-optimized torque converter ne-quattro permanent all-wheel drive. Ngaphansi kwezimo ezijwayelekile zokushayela, umehluko wesikhungo esizikhiyelayo usabalalisa i-torque phakathi kwengaphambili nangemuva ngesilinganiso esingu-40: 60. Uma kwenzeka ukulahleka kwe-traction, iningi le-traction lidluliselwa ku-axle, okuqinisekisa ukudonsa okuhle kakhulu: kuye ngezimo zokushayela, kuze kufike ku-70% ngaphambili kuze kufike ku-85% ngemuva.

Ukumiswa komoya kanye nokuqondisa okuhlanganisiwe 

La i-Audi RS Q8 entsha Ibuye ifakwe izixazululo ezithuthukile zobuchwepheshe ezenza ukuthi isheshe njengemoto yezemidlalo yangempela, yize isayizi nobukhulu bayo. Imoto kagesi etholakala kuma-ekseli ngamunye ilawula ukusebenza kwezingxenye ezimbili zebha ye-anti-roll. Uma ushayela ulayini oqondile, izingxenye ze-anti-roll bar ziyahlukaniswa, okunciphisa izingcindezi umzimba wemoto obhekene nazo emigwaqweni emibi futhi kwandisa kakhulu induduzo. Uma, ngakolunye uhlangothi, umshayeli ekhetha isitayela sokushayela esinemidlalo, izingalo eziyingxenye zihlanganisiwe ukunciphisa ukwehliswa kwe-lateral.

Iphakethe lokuzikhethela leDynamic Plus, ngaphezu kokukhuphuka kwejubane eliphezulu, lifaka i-anti-roll bar esebenzayo, umehluko wezemidlalo kanye namabhuleki e-carbon ceramic. OkujwayelekileI-Audi RS Q8 futhi ifakwe ukuqondisa okuhlanganisiwe. Ngokuyinhloko, i-asi engemuva, ngosizo lwezikulufo nezinduku zokuhamba ezinqamulelayo, ihlinzeka ngokuhamba ngamasondo ngejubane eliphansi ku-antiphase maqondana namasondo angaphambili ngamadigri amahlanu. Ngakolunye uhlangothi, ngesivinini esiphakathi nesiphezulu, amasondo angemuva aqondisa okungenani ama-degree angu-1,5 ohlangothini olufanayo nolwangaphambili, okufaka isandla ekuzinzileni kwemoto.

Okujwayelekile njalo i-Audi RS Q8 entsha Isebenzisa amasondo ayi-intshi angu-10-22-spoke alloy anamasondo angama-295/40. Ngokwesicelo, amasondo angama-23 `` akhulume u-Y-akhuluma ngo-5 atholakala ngemibala ehlukahlukene.
