For one, engine size is not a good determinant of fuel efficiency. If it was, then diesel engines on ships would never get out of the harbor.

But lets not pretend that displacement is unrelated to efficiency. American engines are bigger, and less efficient than their foreign counterparts. The big 3 are way behind on efficient engine design.

To make good power with low displacement you have to run high RPMs and high gear ratios, and to do that reliably requires better design and more precise manufacturing. Take a look at the tolerances on a Japanese vs. American engine, and you'll see what I mean. Japanese cars have an extra digit of precision.
