Hey JasonA, a big factor in the F-bodys is the gearing. When you have a 6 speed with a .5:1 OverDrive ratio, and enough torque to push that you can get 30 MP with 400 HP.

My room mates 94 LT1 camaro gets 29 highway, and like 10 city. HAHA
In 6th Gear at 80 MPH he is doing like 2krpm, and thats with 3.73's.

There are alot of factors when considering milage. I agree that the driver is a very important one.
