Kakaretso e khuts'oane ea likarolo tsa meloko eohle ea BMW 7-Series
Karolo e ikhethang ea lienjineri tsa BMW 7-Series ke molumo o moholo, bonyane lilithara tse peli. Eo nakong ea ts'ebetso e fihletseng rekoto e phahameng ea lilithara tse 6,6, ka mohlala, phetohong ea M760Li AT xDrive, e nchafalitsoeng molokong oa 6 ka 2019. Empa a re qaleng ka enjene ea pele e kentsoeng molokong oa pele oa koloi ena, e leng M30V28.
M30V28 - peterole e nang le bophahamo ba 2788 cm3, e nang le matla a maholo a 238 horsepower le tšebeliso ea mafura ho fihlela ho lilithara tse 16,5 ka lik'hilomithara tse 100. Li-cylinders tse 6 li fane ka torque ea 238 N * m ho 4000 rpm. Ho lokela ho hlakisoa hore enjene ea M30V28 e ne e boetse e kentsoe likoloing tsa moloko oa pele oa letoto la BMW 5, 'me e ne e tsejoa e le "millionaire" e ka tšeptjoang, empa e sebelisoa haholo ka mafura.
