I used to have a 2015 Mirage ES that all of the options and CVT. I got 41 MPG in town and 48-51 MPG Hwy. I loved the car, but one night, I totaled it by hitting a deer. After 5 years, I have to get another car to add to the family fleet and found a 2017 Mirage GT used at dealership. It has all of the options and CVT. The difference that I'm wondering about, is that my 2015 had 14 inch wheels OEM alloy and the 2017 GT has 15 inch OEM alloys. Does the GT still get close to the same MPG? I would think the wheels are heavier etc. If anyone else has a GT or SE with the larger wheels etc., chime in.
