Although I do bet that the car was given more care for both driver, fuel loads and setups than what top gear merely did. But it's great to see the car has been seriously tested. This IS prominently a power heavy track, so it should wipe the floor with lambos and stuff. However, not to be overly joyous. It's still some over 9 seconds slower than a GT3 car over such a distance. At this pace, if the same GT3 car took 625-630 to lap the Ring, the Ferrari would have taken over 7 minutes.
But again the 599xx would have finished the 20.6km configuration in about 6:54, and according to Ferrari, the Laferrari is some 2.7s slower than the fxx at the short fiorano track alone.
