Muviri wemota une makoramu matatu, koramu yepamberi (A column), koramu yepakati (B column), koramu yekumashure (C column) kubva kumberi kuenda kumashure. Kune mota, pamusoro pekutsigira, koramu iyi inoitawo basa refuremu yemusuwo.
Koramu yepamberi ndiyo koramu yekubatanidza yekuruboshwe nekurudyi inobatanidza denga nekabhini yepamberi. Koramu yepamberi iri pakati pechikamu cheinjini nekabhini, pamusoro pemagirazi ekuruboshwe nekurudyi, uye ichavhara chikamu chekutenderera kwako, kunyanya pakutenderera kuruboshwe, saka zvinokurukurwa zvakawanda.
Angle iyo koramu yepamberi inovhara maonero emutyairi inofanirawo kufungwa nezvayo pakufunga nezve geometry yekoramu yepamberi. Mumamiriro ezvinhu akajairwa, mutsetse wekuona kwemutyairi kuburikidza nekoramu yepamberi, binocular overlap Angle yehuwandu i5-6 degrees, kubva pakunyaradzwa kwemutyairi, Angle yekupindirana diki, zviri nani, asi izvi zvinosanganisira kuomarara kwekoramu yepamberi, kwete kungova nehukuru hwakati hwejometri kuchengetedza kuomarara kwakanyanya kwekoramu yepamberi, asiwo kuderedza simba rekudzivirira kwemutsetse wekuona kwemutyairi, idambudziko rinopesana. Mugadziri anofanira kuedza kuenzanisa zviviri izvi kuti awane mhedzisiro yakanaka. Pa2001 North American International Auto Show, Volvo yekuSweden yakaburitsa mota yayo yazvino yeSCC. Koramu yepamberi yakachinjwa kuita chimiro chakajeka, chakashongedzwa negirazi rakajeka kuitira kuti mutyairi agone kuona nyika yekunze kuburikidza nekoramu, kuitira kuti nzvimbo isingaonekwe yemunda wekuona ideredzwe kusvika padiki.
