It's not a dumb question at all. I was wondering the same thing back when I first saw the 570S.
Sorry to disappoint you, but the 570S does not have the ability for you to easily open up the engine cover. For what it's worth, it IS removable. However, it's not a process you'd likely be interested in doing at for instance a car show (which I assume is why you're asking about this). You'd first need to remove two screws located under the small flap that pops up (where you'll find the engine oil filler and coolant filler). After those screws are removed, I believe it's just a matter of lifting up the engine cover on the backside to release it from some retaining clips and then carefully pulling outward toward you, all while being sure not to scratch the palladium gray trim surrounding the engine cover.
