On average, I would get 32mpg with the Focus (manual). I can't say for sure how much better the Mirage will be as I'm still getting the hang of keeping that ECO light on, or <3,000 RPM. But I have seen people get over 40mpg in their Mirage which is exciting. The decrease in horsepower is noticable but it won't cause me to be late to anything and I can still overcome people on the highway in needed.
