Not one, but two LaFerraris flat at at Fiorano. And no errors this time.

What can we learn from this video? First of all, the LaFerrari sounds awesome. Especially the camouflaged one, which seems to have a different exhaust. A louder one. Also, there's some active aero action going on with that rear spoiler...

The Porsche 918 is the fastest so far, and the McLaren P1 is obviously so impressive that Jay Leno bought one already. But what's up Ferrari's sleeve?
