Keel-less?

[j4kwan]

How does McLaren's new Keel-less design work? What are the significant advantages/disadvantages of this design over twin-keel, v-keel, single keel?

Its stiffer, lighter and cleaner aerodynamically, the problem is making the suspenions geometry work with the raised lower wishbone (plus the lower wishbone may have a higher loading and hence be heavier)
