Igqabi sisigqubuthelo (iqhekeza eliphuma kancinci, eliyi-semi-circular ngaphezulu kwevili) kwizithuthi zeemoto nezingezizo iimoto, njengoko igama lisitsho, eligubungela iqokobhe langaphandle lezithuthi zeemoto nezingezizo iimoto. Ngokuhambelana nolwelo, yehlisa i-coefficient yokumelana nomoya, vumela imoto ihambe kakuhle.
Ibhodi yamagqabi ikwabizwa ngokuba yi-fender (ebizwa ngokuba yimo kunye nendawo yale nxalenye yomzimba wemoto endala efana nephiko lentaka). Iipleyiti zamagqabi zifumaneka ngaphandle komzimba wevili. Umsebenzi kukunciphisa i-coefficient yokumelana nomoya ngokwe-fluid dynamics, ukuze imoto ihambe kakuhle. Ngokwendawo yokufakela, inokwahlulwa ibe yipleyiti yamagqabi angaphambili kunye nepleyiti yamagqabi angasemva. Ipleyiti yamagqabi angaphambili ifakwe ngaphezulu kwevili elingaphambili. Ngenxa yokuba ivili elingaphambili linomsebenzi wokuqhuba, kufuneka liqinisekise indawo ephezulu yomda xa ivili elingaphambili lijikeleza. Iphepha elingasemva alinangxaki yokujikeleza kwevili, kodwa ngenxa yezizathu ze-aerodynamic, igqabi elingasemva line-arc egobileyo kancinci ephuma ngaphandle.
Okwesibini, ibhodi engaphambili inokwenza inkqubo yokuqhuba imoto, ithintele isanti eqengqelekayo kwivili, udaka luchitheke ezantsi kwenqwelo, inciphise umonakalo kwi-chassis kunye nokugqwala. Ke ngoko, izixhobo ezisetyenzisiweyo ziyafuneka ukuze zibe nokumelana nokuguquguquka kwemozulu kunye nokusebenza kakuhle kokubumba. I-fender engaphambili yeemoto ezininzi yenziwe ngezinto zeplastiki ezinobungqingqwa obuthile, ukuze ibe ne-cushion ethile kwaye ikhuseleke ngakumbi.
