Cabanga ukuthi uMike Tyson wakwazi ukudansa i-ballet yakudala. Amandla amakhulu ahlanganiswe nokushesha nokunemba. Ngakho-ke, i-Audi SQ7 entsha ilingana naleyo enguqulweni yemoto. Kwakuwumuzwa esasinawo kulokhu kuxhumana kokuqala.
Amandla amakhulu kanye nobukhulu be-XXL. Ukufunda kafushane ishidi lobuchwepheshe le-Audi SQ7 entsha kwanele ukuze uqiniseke ukuthi sibhekene ne-SUV enkulu, kokubili ngamandla kanye nobukhulu. Isisindo esingu-2330 kg, amandla angu-435 hp kanye ne-torque engu-900 Nm ku-1000 rpm(!), i-Audi SQ7 ikwazi ukufeza u-0-100 km/h ngemizuzwana engu-4.8 kuphela.
Uma lawa manani emangalisa eshidini lobuchwepheshe, ngemuva kwesondo ahlaba umxhwele nakakhulu. Ngabe i-Audi yakwazi kanjani ukwenza lesi sisindo sosondonzima sibe umgijimi onekhono? Ngizokunikeza impendulo emigqeni embalwa elandelayo.
Injini engu-4.0 TDI ithuthukiswe ukusuka ku-"zero"
Uma ukhumbula kahle, iDizili enamandla kakhulu emakethe isivele ingeyakwa-Audi — bona iTop 5 yezinjini zikaDizili zanamuhla lapha. Anganelisekile, uhlobo lwaseJalimane lwanquma ukuthuthukisa kusukela ekuqaleni injini entsha engu-4.0 litre TDI V8 bi-turbo esekelwe i-electric volumetric compressor (EPC).
Njengoba ngike ngasho, ishidi lobuchwepheshe lale injini liyamangalisa: inamandla angu-435 hp ku-3750 rpm kanye ne-torque engu-900 Nm engashintshi phakathi kuka-1000-3250 rpm. Ngamanye amazwi, ine-torque ephezulu etholakalayo kusukela ekuqaleni!
Ukuzuza lawa manani kwenzeke ngenxa yokwethulwa kokuqala kwe-volumetric compressor eqhutshwa ngogesi (okuthiwa i-EPC) enesibopho sokuhlinzeka ngama-turbocharger ayimishini lapho ungekho umfutho wegesi owanele wokuvula izinjini zabo zomoya. Umphumela? Ithuthukisa ukulethwa kanambambili futhi icishe iqede "i-turbo lag" yendabuko.
Ngokuqondene nama-turbocharger angumshini, acushwa ngokomqondo womthwalo olandelanayo: eyodwa yenza ngesivinini esiphansi nesiphakathi kanti eyesibili icushwa kuphela ngesivinini esikhulu (ngaphezu kuka-2500 rpm). Okunye okubalulekile kohlelo lwe-EPC ukuthi lunikwa amandla uhlelo lukagesi lwe-48V okuzothi maduze nje lube nesibopho sokunika amandla amanye amasistimu (kodwa abekuwo…).
imizwa ngemuva kwesondo
Ngathumela i-database esihlalweni esingemuva futhi ngaqala nge-SQ7 nge-Dynamic mode (eyezemidlalo kakhulu). Kwangathi ngomlingo i-2330 kg yesisindo yanyamalala futhi ngashintshwa ngafinyelela ku-100 km/h ngemizuzwana engaphansi kwemihlanu. Kucishe kufane nokukhahlela indlu enamagumbi amabili.
Kusukela lapho kuya phambili, umugqa wenjini ungangoba ifihla amandla e-435 hp. Nokho ngibheke i-speedometer futhi “ini?! Usuvele uhamba ku-200km/h?”. Ngamanye amazwi… ungalindeli ukuzwela okukhulu njengemoto yezemidlalo, yilinde(!), injini eyindilinga, ehlala itholakala, ekwazi ukwenza le SUV yamathani angu-2.3 ngendlela yemvelo eyeqa imithetho yefiziksi. Ngaphezu konya, inkulu kakhulu.
Ngokwehlisa ijubane nokukhetha i-Comfort mode, iyi-Audi Q7 njengamanye amaningi: eyakhelwe kahle, entofontofo kanye nezobuchwepheshe.
"Ngamandla omlilo" angaka, amajika afika ngokushesha kunokuvamile emotweni engaphezu kwamamitha amahlanu. Ngenhlanhla i-Audi ayizange ilinganisele ku-powertrain futhi isinikeze amandla ahlukile - ngaphandle kwalokho le Q7 ibingeke ithole ukuqokwa kwe-SQ7. Njengosizo ekubambeni amabhuleki, sathola amadiski obumba amakhulu elunywe ama-caliper angama-piston amane.
Uma sekuyisikhathi sokufaka uMike Tyson (ngaleyo ndlela engiqambe ngayo i-SQ7) kumajika, siyamangala ngokunemba hhayi komshayisibhakela, kodwa komdansi wakudala. Ama-stabilizer bars asebenzayo (amandla kagesi akwazi ukuphehla amandla angu-1200 Nm) anciphisa ukutsheka komzimba, kanti amasondo amane okuqondisa akhomba i-Audi SQ7 lapho sifuna khona.
Njengoba uphuma ekhoneni, isistimu ye-quattro traction kanye nomehluko wangemuva wezemidlalo one-torque vectoring kubeka wonke amandla phansi.
I-Audi ibiza inhlanganisela yalezi zinhlelo ngokuthi “ukulawula ukumiswa kwenethiwekhi”. Wonke amasistimu asetshenziswa iyunithi yokulawula okwabelwanayo eyenza imisebenzi ibe phakathi nendawo eqinisekisa ukuxhumana okuphezulu kwawo wonke amasistimu. Kukho konke lokhu, ngabe sengikhohliwe ukuthi bengishayela iSUV enesisindo esingaphezu kwamathani amabili? Yebo, okwesikhashana yebo.
Isiphetho salokhu othintana naye wokuqala
Uhlobo lwe-Ingolstadt lukwazile ukuhlanganisa kule SUV enezihlalo eziyisikhombisa amandla omzimba womshayisibhakela nokukhanya kokunyakaza kwe-ballerina. Uhlobo lwezinto ezingafezwa kuphela kusetshenziswa ubuchwepheshe besimanje, ikakhulukazi uhlelo lwe-48V olubhekele ukunika amandla i-EDC kanye nezinsimbi zokuzinzisa ezisebenzayo - esikhathini esizayo esiseduze lesi simiso sikagesi sizosetshenziselwa ukunika amandla izinhlelo zokushayela ezizimele futhi ukuze kusetshenziswe amandla e-kinetic akhiqizwayo (abengamoshwa).
Yehlisa ijubane «elisheshayo» nokukhetha imodi ye-Comfort, i-SQ7 iyi-Audi Q7 njengazo zonke ezinye: eyakhelwe kahle, entofontofo kanye nezobuchwepheshe. Ngokuqondene nokusetshenziswa, ngezikhathi ezimfushane ukuthi ngahamba ngemodi "ejwayelekile" ngakwazi ukufinyelela isilinganiso esingama-9.0 amalitha - akukubi ku-boxer.
Kukho konke lokhu, i-Audi icela i-€ 120 000, ngokubona kwami cishe isibopho sokwengeza imigoqo yokuqinisa esebenzayo, i-axle yangemuva eqondiwe kanye nomehluko wezemidlalo (uyazikhethela, ngaphandle kwenani eliqinisekisiwe). Kuphakathi noma akunjalo! Ngimlindele e-Portugal komunye «umjikelezo we-ballet», kulokhu emigwaqweni kazwelonke…
