The math says 3054lbs "dry".
The 3.5EB weight 417lbs "dry" and 450lbs dressed.
Ford Performance director Dave Pericak states that adding vital fluids, minus fuel, brings the GT's weight up to 3173 lbs.
It carries a 15.2 gallon fuel tank, gasoline weight 6lbs per gallon, when full that would add 91.2lbs.
"Total" curb weight comes to 3264.2lbs.
However US curb weights are typically given when the vehicle is measured at "nominal" fuel levels, so measured as 1/2 capacity that brings us to 3218.6lbs.
