yaris with a metro motor .. SLOW as heck.. but it may work , after all i saw a 10 hp diesel ina metro and it did 50mpg.. but a yais is 1200 lbs more than d the 1800 lbs metro..
However yes EPA on a Yaris 5speed is 36mpg, however, I bet you can pull 43-45 from it with hypermiling, I get 35mpg in my chevy colorado pickup its rated 25 mpg..
