Crusing my Mustang
At Highway speeds, having the windows up and the AC on if needed will get better gas mileage. Plus the noise and buffeting just gets annoying to me after a while. Window glass blocks most of the UV so you wont get drivers tan. My data center display shows 25.5 to 27 MPG at 75 Mph with the AC and CC on and 27.5 to 29 without the AC. And on one test over about 20 miles of flat I saw it reach 32MPG at 60 MPH on the CC. This is a shade better than my 97 Probe GTS with its 2.5L V6! Both with manual transmissions. Amazing.
