Same with the sedan and wagon. And if they're trying to get more cooling to the brakes, the current design is plenty ample for street use. But at a track you can never have enough brake cooling. So I imagine it's a nod to those who would probably drive the E92 harder and faster than any of the other models.
I know of many sedan competitive track cars out there. e90 being one of them. The e92 and e90 weigh almost identical. The coupe doors have to make up for the loss of the B pillar which the e90s have.
From the BMW website:
If anything I find it odd they added the e93, but there are people who like the verts.
