We know Chevrolet is showing off two cars at the 2011 Chicago Auto Show, and one is likely based on the Chevrolet Camaro platform. We're guessing that the long-awaited 2012 Chevrolet Camaro Z28 will bow, but anything could happen.

Although all rumors and signs point in that direction, instead of the Z28, we could see a rear-wheel drive sedan. Or perhaps something else.

For full coverage, check back here shortly after the reveal happens at 9:15 Central time on Wednesday.
