Not long ago I was heading outta state with some family and my uncle has a HHR SS turbo, so we line them up from about 60 roll on and punch it, well when we finally got to where we hit the gas at the same time I had him by about atleast a car length by 100( I had 3 ppl in my car he had 2) still though his car was much quicker than I woulda thought. still couldnt take the old GXP tho.
