It is no surprise that the two smallest cars in the Honda Vs Toyota comparison chart, get the best fuel ratings. The Honda Fit and the Toyota Yaris are the two vehicles that we are talking about. And the winner is: The Toyota Yaris. It comes in with an EPA average rating of 29 miles per gallon in the city and 36 miles per gallon on the highway. The Honda Fit on the other hand is close, but does end up falling just short with 28 miles per gallon in the city and 35 miles per gallon on the highway.
