I own a blue 2015 CT F-Sport, and the best advice is don't expect it to be any more car than it's meant to be. It's only 134hp, so it's not a sportscar. It's a hybrid, so don't expect a sweet engine growl. It can still be quick zipping around town or some back roads in Sport mode though! If you want the most out of your gas mileage, watch some Youtube videos on Hypermiling and try it out for yourself.
