Sena sea thahasellisa! Nakong ea tlhahiso ea tlhahiso e kholo, letoto la B58 le ne le emeloa feela ke enjene ea B58B30M0, lienjineri tse ling kaofela li ile tsa hlaha hamorao ka lebaka la tlhokahalo ea ho lumellana le motlakase ho moralo oa koloi e itseng. Letoto lohle la B58 le na le litšobotsi tse tšoanang tsa tekheniki, empa li fapane ka boholo le sistimi e ntseng e eketseha.

Litlhaloso: ke eng e khethehileng ka mefuta ea BMW B58B30, B58B30M0, B58B30O0?

Ntho e ka sehloohong ea li-engines tsa B58 ke 'mele o entsoeng ka aluminium le carbon fiber, e leng se entseng hore ho khonehe ho fokotsa boima ba lisebelisoa tsa matla ho 100 kg. Li-motor tse bobebe li bonolo ho kenya koloing efe kapa efe, ho sa tsotelehe meaho ea 'mele, e netefatsang kabo e leka-lekaneng ea boima.

B58 ea li-cylinder tse tšeletseng e tšoauoa ka matla a phahameng le ts'ebetso, e hlalosoang ke tlhahiso ea lisebelisoa - har'a likarolo tsa moralo ke:
