Yes its WAY to early for an SV model, that should be the last in the generation, Maybe an LP780 or something, The pressure of performance is getting critical.
I also believe this wont have the same performance as a base LP700, 20Bhp more should increase its top end given the drag isnt messed with much, new splitter and rear diffuser should also improve track times minimally, along with a faster shifting tranny.
Although it looks a bit plain in the back, i wouldnt mind seeing a small one like the Murcielagos and Diablos had.
