What made it an SS? The engine, suspension and trim. The HHR SS had a 2.0 Turbo that was about 250HP stock, an upgraded FE4 sport suspension and of course the appearance package. the 2.0T of that era had a GM stage kit upgrade that boosted the horsepower from 250HP to 290HP in the FWD HHR SS and Cobalt SS and 325HP+ in the RWD Pontiac Solstice/Saturn Sky.OMG do you mean the HHR SS
OMG do you mean the HHR SS that only old people thought was a good looking car because the design was "retro"? What was SS about it. Do you like the Mission Joke?
