R&T timed the Si at 15.1 and the SS at 14.8 for the 1/4. Not that noticable really, considering that margin could be made up or lost by the driver. The Cobalt SS is an easier car to drive fast, but not necessarily faster.

C&D and MT both got 1/4 mile times that were lower than that...14.4 and 14.5 respectively so I have to believe that R&T's time was on the high side. I couldn't find much on the Si...but either way a half second 1/4 mile and almost a full second 0-60 is definitely noticeable faster.

In the context of everything else...its fuel efficiency really isn't that impressive.

It seems to be right in the same league as anything else comparable out there......I'd be thrilled to get low-to-mid 20's in a Cobalt SS Supercharged as well...
