We recently drove from Cincinnati, Oh. to Niagara Falls. I cruised at 75-80 MPH, only used the A/C about 1/2 the time. We avereage 25 MPG. Comming home we used the air most all the time and got 23-24 MPG. I am pretty happy with that kind of mileage with a 300 HP V-8 convertible.

That's exactly what I average on the highway with my 5-speed manual GT.
