I'm looking at getting a 2013 GT over the next couple of weeks and curious about gas mileage on the GT's that have the Track Package (3.73 gears). I will be driving the car roughly 300-400 miles a week.
Yea, it's 16-16.5 somewhere in there. That 27 MPG was with 3.73's and a 91 octane tune
Open road with '11 GT w/o tune is getting around 22-23 on 91 octane with the 3.73 gears. Daily driving city/hwy I average 20 MPG. Keeping my foot in it I average more around 18. So yeah, all depends on how heavy your foot is. I saw 24 once but haven't seen close to that in awhile.
