The reason is simple. Cars long ago lost large (big cube) engines. Now a large displacement engine has to make an attempt at achieving volumetric efficiency (maximum cylinder filling). This equates to larger volumes of fuel/air mixture which equates to lower fuel economy. Enter CAFE (the Corporate Average Fuel Economy dictated by our stupid government weenies).

So for a manufacturer to deliver both a decent level of performance AND satisfy CAFE requirements (27.5 MPG across the board) he has to install smaller engines (less cubes) and go for blowers to get the performance quotient.

I, too, prefer a larger engine, mainly because of the increase in torque. Torque is a factor of cylinder filling.. either derived from cubic inches of forced induction.
