What benefit is there for BMW to spend time and materials designing an engine that will handle 700Hp when they never intend for it to see more than 350Hp? It doesn't make sense from the manufacturer's point of view.

this is exactly what i was thinking....toyota meant to build a great engine but really had no idea what kind of power it could really handle and just decided to over engineer it... and the reason BMW didnt build a 700hp engine is like u put, an unintended purpose
