Okay everyone seems to always put up the whole "who will win" (im even guilty). So here is a website that might help everyone out a little bit.
www.consumerguide.com do the automobile section... and figure it out from there. You can get hp ratings, weights, lengths, etc... for just about everything from like 90s and up. Probably one of the most informational car sites there is IMHO.

Hah consumerguide isn't normally so nice to us:

"Supercharged includes boost gauge on left windshield pillar, plus jazzy two-tone leather sport seats and metal-look cabin trim. Nothing looks or feels cheap--a big step up for GM compacts." - http://consumerguideauto.howstuffworks.com/2007-chevrolet-cobalt-1.htm

Nice find. I'm sure a lot of people will find that site very useful. All road tests will be different though, so its a rough estimate at best when it comes to "who will win" situations.

no no no...its motortrend that isnt nice to us, saying our interior is "Generic"

yeah I think all the specs that they give on the cars are fairly accurate.
