Another "demo" from Ferrari at the Challenge was their sorta new FXX, based on the older Enzo. Again, Ferrari claims this is a "production" car (if you buy one, it comes with its own mechanic), but I doubt you'll see one on the streets. An amazing vehicle, what an engine roar!
Some pics from the garage:
And another brake pic:
And, of course, Ferrari red...
Here's a brief video of FXX track laps (the white car is a 599XX).
