*I printed off a blueprint of the coupe and sized it to fit my contours.
* The sedan and coupe are identical in both width and height.
* They're within a fraction of an inch in length.

* Without the rear wing, the upper trailing edge of the deck is a match for the 2013 template.
* I've no idea whether the SS high-mounted spoiler is decorative, intended for direct downforce, nor whether it reduces, or increases drag.

* The only Cd available for the Cobalt is for the 4-door sedan SS, at 0.324.
* This SS also has 1-inch extensions to the rocker panels and both fascias.
* There is no brake-horsepower/drag-limited top speed data available for the car.
