As far as the Fusion goes, I see that the back end of the spoiler certainly matches up with the face of the trunk, but to my eye, it sure seems like the beginning of the spoiler is raised a bit (maybe less than an inch), and I only say this because if they did raise it an inch at the beginning, they did it for a reason. But it is no matter anymore. |
It might be beneficial if we qualify a context in regards to wakes when discussing quanta associated with them.
The type of vehicle design (squareback/notchback/fastback),etc.,has much to do with the wake and how it might be managed.
I'm guilty of pushing the smaller wake,in context to the 'Template' moving the separation point rearwards, such that when the air finally does separate,t
he wake produced is smaller and of higher base pressure,and free of attached vortices,all leading to lower pressure drag,and with it,lower profile drag.Hucho states that this is the premise of streamlining.
Since the wake is turbulence by definition,and streamlining reduces the size of of any given vehicle's wake,we've been using this relationship as a talking point.It is a bit of a convention.
