I'd like as many 0-60 and 1/4 mile times of all models of Cobalt.

Like LS Coupe, LS Sedan, LT Coupe, LT Sedan, SS Coupe, SS Sedans from all years.

In particular I'd love to see the specs on
LS and LT Coupes, stick and automatic from 2008
and LS and LT Coupes, stick and automatic from 2009.

I wouldn't think like that. Cars cannot drive themselves, it depends on the driver, the condition of the vehicle, the condition of the track and the weather. I wouldn't bother to compare 0-60 times from one car to another and expect that to be reality. Another thing is that 0-60 is time to speed not time to distance so 0-60 does not tell the whole story anyway all else equal. One car mag can get a Cobalt LT sedan /14 mile in 17 seconds and another in 16.5... read it for entertainment not factual information.

All that said... just google it.
