No; the hybrid does not necessarily have to result in a savings on fuel versus non-hybrid gasoline cars. There are also other thermodynamic-related costs, such as the expense of more moving parts and all that.

I know that my hybrid gets 400+ miles to a 10 gallon tank of gas, while my prior car got only 200 miles for the same 10 gallons.

That's an MPG of about 40 vs. the 20 I was getting. Wouldn't that mean that my hybrid is putting out less emissions per miles driven since it's double the miles for burning the same 10 gallons of gasoline?
