True vettes get way better gas mileage than expected. My Stingray with just headers intake tune ran 11.2 at 125mph and can get over 30mpg on highway. Love the car.

Another option is to swap in an LS. I can get ~30mpg highway, but normally ~26mpg with about 20% city, and 80% highway.

I would be surprised if they could not get over 30 on the highway with the highway rating of 29mpg.
