The ZR-1 is rumored to have a blower. You can only assume that there is a blower under that cover. Unless there is a change in body work the ZR-1 will look like a "regular" C6. I was hoping for some type of body change for this model. The hood is a change in direction with that cut out but just about every manufacturer has had the "shaker hood". Pontiac Trans Am, Challenger/'Cuda and Mustang.
