three main things I've noticed will drag the Yaris mpg down :
1) Hotdogging. Enjoy it, but you will pay in reduced mpg. You knew it, come on.
2) Cold temperatures drag the mpg down during the cold engine (rich mix) time, drops mpg 1 to 1.5 less.
3) Using the AC drops mpg 1 to 1.5 less. It really is a little engine...

It is true, what hurts most is the size of the engine. it can be economic only when driven smoothly. For some reason I enjoy smaller engines... There are even something like 1.3 and 1.0 Yaris engines. Those don't have that much power, somewhere about 60-70Hp I guess, but then who really needs 100Hp

90% of the time most people will only use 50% of the available engine power
