 The exterior of the car is made entirely of carbon fibre reinforced plastic and is similar in shape to the Ferrari 330 P4 as Glickenhaus requested , however it has been called a " rolling history of Ferrari @-@ racing @-@ DNA " sharing elements from several historic Ferrari vehicles , not just the 330 P4 . The rear window is similar to that of the Ferrari 512S , the side vents are similar to the Ferrari 330 P3 and the nose is similar to that of the Ferrari 333 SP which improves cooling and the car 's frontal crash safety . The butterfly doors ( similar to those of the McLaren F1 ) are designed such that even at 160 mph ( 260 km / h ) there is no wind noise . The improved aerodynamics give the car greater downforce , yet less drag , than the Enzo , which makes the car more stable than the Enzo at high speeds .
