Q4 - Imoto
Lena idrayivu edonsa ngawo wonke amasondo ehlala njalo esetshenziswa ngabakwa-Alfa Romeo. Uhlelo lusebenza ngomgomo wokuhluka kwesikhungo se-Torsen, okulandelwa ukuhluka kwesikhungo se-bevel. Ibekwe endlini evamile enomehluko wangaphambili futhi isabela kumehluko we-torque. Ngakho-ke, ukushayela kwawo womabili ama-ekseli ngokuqhubekayo kusabalalisa amandla enjini phakathi kwamasondo angaphambili nangemuva. Ngaphansi kwezimo ezijwayelekile, u-57% we-torque uhamba ngeTwinDiff limited-slip differential iye emasondweni angemuva, bese kuthi u-43% osele uye emasondweni angaphambili. Lesi silinganiso segiya silungele izimo ezomile nezingathathi hlangothi lapho imoto inohlamvu olufana nolwemoto edonsa ngamasondo angemuva. Ezimweni ezimbi kakhulu, umehluko we-Torsen ungasabalalisa i-torque kusuka ku-22:78 kuya ku-72:28 phakathi kwama-ekseli amabili. Ngale ndlela, ukushayela kwawo womabili ama-axles e-Q4 akuthuthukisi nje kuphela ukubamba ezindaweni ezishelelayo, kodwa futhi kugcina ithrekhi inyakaza ngokucijile. Lolu hlelo lusize ekuqedeni i-understeer lapho kunqunywa khona, ngakho uma kwenzeka i-skid, imoto ngeke ihambe iqonde, njengoba kwenzeka kumasondo angaphambili, kodwa kahle emaceleni ngawo wonke amasondo amane. Nokho, akufanele enze ihaba ijubane ukunyakaza, njengoba umshayeli onolwazi kakade kudingeka ukubamba ezishelelayo, futhi esimweni Alfa 159, ngisho cishe amathani amabili ATV. Futhi lokho kuyisisindo esiningi, elehlisa kancane ikhono le-ATV enenjini esindayo. Ekuqhathanisweni kokugcina, i-handguard elula ene-1,75 TB encane futhi elula, kodwa futhi ne-1,9 JTD, ngokulandelanayo. 2,0 I-JTD ayimbi kakhulu. Inzuzo yohlelo lwe-Q4 amandla emishini, ukonakala okuhlobene ukucinana okuphezulu okulinganiselwe okuvela kumgomo wokuklama. I-Q4 ingatholakala, isibonelo, kumamodeli we-Alfa 159, 159 Sportwagon, Brera ne-Spider.
