You see a modern BMW with a small bonnet, still have I6 engine. I don't understand. Or my guess is the car manufacturers want save materials... but not save engine materials, only body material... do you understand what I mean like V6 engine get more timing chains, 4 cam sprockets with 4 camshafts plus 4 vvt solenoids and 2 valve covers with many bolts... AND I6 engine get 2 timing chains with 2 cam sprockets, 2 vvt solenoids, 2 camshafts and one valve cover. Which is waste materials... V6 or I6? What do you think?
