Imashini nini ya Monolithic ipfa gukata ntabwo ikora gusa mubikorwa byo gukora, kubinyabiziga ubwabyo, kuko bigabanya akazi ko gutera kashe no gusudira, bityo birashobora gukemura byimazeyo ikibazo cyijwi ridasanzwe ryumubiri;Kubwumutekano, inzira ihuriweho hamwe nayo izazana igishushanyo mbonera cya modular, byanze bikunze bizahagarara mugihe umutekano wumubiri uzaba mwiza cyane.

Umutekinisiye afite ibitekerezo byinshi byo guhangana n'umutekano utunguranye.Mu gishushanyo mbonera cyimiterere ya Model Y, ibintu umunani byo kugongana, nko kugongana imbere, kugongana kuruhande no kuzunguruka, birasuzumwa.Tesla irashobora kuyobora neza no gukoresha imbaraga zingaruka zo kugongana hifashishijwe igishushanyo mbonera cyimiterere yumubiri, imbere ninyuma yo kurwanya ibyuma birwanya impanuka, agasanduku gakurura ingufu nibindi bikoresho kugirango birinde umutekano wabayirimo muburyo bwose.

Umubiri wa Model Y ufata ibyuma-aluminium bivanga umubiri, kandi ibice byingenzi bishimangirwa nicyuma gikomeye cya boron, gishobora kwihanganira imbaraga nini.Ikomatanyirizo rya termometero imbere n'inyuma (impeta ya boron), ibisenge by'imbere (ibyuma bya boron), hamwe n'ibiti byo hejuru (ibyuma bikomeye cyane) bigize imiterere ifunze impeta itanga inkunga ikomeye kumubiri wa Model Y.Igishushanyo mbonera cyuburyo bwo gushyira ipaki ya batiri hasi yimodoka nayo yazamuye cyane imbaraga zuburyo rusange bwa Model Y, bigabanya ibyago byo kuzunguruka no gutera ingaruka.
