I am averaging 48 mpg while always starting from a dead stop in Sport mode. I found the lag in eco mode almost unsafe. I also switch to Sport when looking to pass or climbing hills, the drop in mpg is worth the assurance of accelerating when I want to. I drive 500 miles a week and the best I have achieved is 55 mpg. The car handles very well and is fun to drive, but after test driving a dozen vehicles in the past month, I find the suspension/road noise from bumps to be louder than I remember on my test drive when I bought it in March of this year. That is the trade of for high mpg I guess. Be sure to keep a log of ANY issues that you EVER experience (time/road speed/weather conditions/duration). I was sold the Extended Service Plan by the Finance Manager because in his words "this is a new model and new technology". Very humorous because my Niro EX began having issues at 1500 miles/3 weeks. (More on that in another post to come.)
