What are the merits of I6 engines over V6
#51
One item not mentioned is the fact that many engines are now made of Aluminum rather than iron. Therefore the shorter the engine, less expansion takes place. On a V6 the difference in expansion (especially with aluminum) between the head and block is considerably less than on a I6. BMW is one of the few manufacturers that have sucessesfully engineered the gasket material on their I6 to prevent head gasket leaks do to the expansion problem.

I don't really have anything to add to this convo since everything's pretty much been said, so I just figured I'd throw in some eye candy. Enjoy.
