The cape is shaped like a diffuser, indeed it's like a miniature car underfloor with a raised front edge and diffuser at the rear. The diffuser section is obviously being used a vortex generator and director. The vortex will be in the opposite direction to the Y250 one.
I think I suggested that last year, when we first saw the cape. Looked like they were creating a low-pressure area under the nose, just like the floor of the car, and the air spilling off the sides of the nose would generate a vortex spinning in the opposite direction of the Y250, but I thought the spacing would serve to strengthen the Y250, since they'd both be spinning towards the ground in the space between them. I don't know the aerospace/aeronautical terminology, so can't describe it better than that, or by twirling my hands in the air, which you can't see. LOL.
