that was posted when it appeared in Winding Road, as noted WR "commisioned a rendering" so it's a photoshop and according to those who claim to have seen the real deal in Paris it's not very accurate so who knows?
You need vents to get air moving into the engine bay, funneled to the front brakes and even to be channeled under the car to create ground effects. The Porsche vents (and Ferrari vents) are not cosmetic...serious cars need them. If you have to have them, might as well make them attractive. I think these actually look better than the ones on a 911 Turbo.
