Iqabunga yisembozo (ucezu oluphume kancane, oluyindilinga ngaphezu kwesondo) ezimotweni ezinenjini nezingezona izimoto, njengoba negama lisho, limboze igobolondo langaphandle lezimoto nezingezona izimoto. Ngokuhambisana ne-fluid dynamics, nciphisa i-coefficient yokumelana komoya, vumela imoto ihambe ngokushelela.
Ibhodi leqabunga libuye libizwe ngokuthi i-fender (eqanjwe ngokuma kanye nendawo yale ngxenye yemoto endala efana nephiko lenyoni). Amapuleti amaqabunga atholakala ngaphandle komzimba wesondo. Umsebenzi uwukunciphisa i-coefficient yokumelana komoya ngokuvumelana ne-fluid dynamics, ukuze imoto ihambe kahle. Ngokwendawo yokufaka, ingahlukaniswa ipuleti leqabunga langaphambili kanye nepuleti leqabunga elingemuva. Ipuleti leqabunga langaphambili lifakwe ngaphezu kwesondo langaphambili. Ngenxa yokuthi isondo langaphambili linomsebenzi wesiteringi, kumele liqinisekise umkhawulo wesikhala esiphezulu uma isondo langaphambili lizungeza. Iqabunga elingemuva alinakho ukungqubuzana kokujikeleza kwamasondo, kodwa ngenxa yezizathu ze-aerodynamic, iqabunga elingemuva line-arc ekhotheme kancane ephumela ngaphandle.
Okwesibili, ibhodi leqabunga langaphambili lingenza inqubo yokushayela imoto, ivimbele isihlabathi esigoqelwe isondo, ibhuqe phansi enqoleni, inciphise umonakalo ku-chassis nokugqwala. Ngakho-ke, izinto ezisetshenziswayo ziyadingeka ukuze zibe nokumelana nesimo sezulu kanye nokuhleleka okuhle kokubumba. I-front fender yezimoto eziningi yenziwe ngezinto zepulasitiki ezinokunwebeka okuthile, ukuze ibe nokucushwa okuthile futhi ivikeleke kakhulu.
