This video was taken at Fiorano of what seems to be the test mule for the replacement 612 Scaglietti. I'm sure Ferrari use more than one test mule as when looking at the pics below, it shows the car with the same headlights and rear lights as per the 458. The similarities between the car in the video and the car in the pics would be the colour of the car, the wing mirrors, front grill and the extension of the exhaust pipes sticking out. So this gives us a claer sign that both mules are related to the same project.
I must say it sounds very nice and different to the current 612 as far as I can remember what the current 612 sounds like.
