Kubatsira kukuru kwekabhoni fiber nderekuti inorema isingasviki chikamu chechina chesimbi uye yakareruka kupfuura aruminiyamu, zvichiita kuti ive chinhu chakanakisa kuwana "huremu". 30 muzana yakareruka kupfuura aluminium uye 50 muzana yakareruka kupfuura simbi. Kana zvikamu zvose zvesimbi zvemotokari zvakatsiviwa ne carbon fiber composite zvinhu, uremu hwemotokari hunogona kuderedzwa ne 300 kilograms. Carbon fiber ine simba rakapetwa makumi maviri pane iron, uye ndiyo chete chinhu chisingarasikirwe nesimba pakupisa kwe2000 ℃. Yakanakisa kukanganisa kunyudza simba ndeye 4-5 nguva yeyakajairika simbi zvinhu
