Why does BMW use so much composite plastic in the engine compartment?
I've owned multiple BMWs where the generations have ranged from the late 80's to early 2020's. What I've noticed is that if the generation was built after 2010-ish, there are more and more parts that used to be cast aluminum, but are now composite plastic. E.g. - radiator hose manifolds/couplings, charge pipe connectors, etc.
I've heard varying explanations for this from independent mechanics and shop owners. "It's to save money", "It's to save weight", "It's for packaging", "Because BMW wants you to go to a dealer and take your money", etc etc
Does anyone have a definitive, educated answer?
