Technically they are.
What Chevy did was bring out the SS first (its called SS 'Supercharged', 'supercharged' being the key word here) in addition to the regular cobalt, so they could get a toehold into the sport compact market with a good offering.
The next year they introduced the midrange (which is plain jane SS) to cover the gap that the first two cars leave (lowish end cobalt, then jumps to high end SS superchargeD).
The SS supercharged and SS regular look ALMOST exactly the same. The difference being that the SS regular is available on the 4 door sedan. And the SS coupes have less ground effects stuff and smaller tires than the SS supercharged.
So simply put:
Cobalt LS/LT > Cobalt SS > Cobalt SS supercharged.
This is why the whole damn thing gets confusing because as soon as you mention SS everyone automatically assumes the supercharged version.
