If diesel engines are more efficient why do most cars have gasoline engines?

I have read the articles on diesel and gasoline engines. Several of my friends drive Mercedes turbodiesels and I have seen several diesel hummers. I was wondering that if diesel engines are more efficient and use cheaper fuel why don't all cars use diesel?

How Quasiturbine Engines Work

The quasiturbine engine takes the Wankel concept and improves on it: Instead of three combustion chambers it has four and the setup of a quasiturbine allows for continual combustion. Learn all about the quasiturbine.

How HEMI Engines Work

Even if you don't know much about cars, the word "HEMI" might still mean something to you. It's become a synonym for big, powerful engines.

This may sound silly but on the back of my car there is a little sign that says "2.4 liter" and every morning I see that and wonder "What does that mean?" So what does it mean?
