Ferrari 2006 FXX

The price for this ultimate Walter Mitty fantasy: 1.6 million Euros--nearly two million U.S. dollars (that sum does include a custom driving suit and helmet, though). And, yes, all 29 FXXs are already sold.

Ferrari's code name for the Enzo was FX, so adding an extra "X" seemed appropriate for a follow-up car with something extra--and then some. The FXX is designed to run on specially made 19-inch Bridgestone slicks. Behind the FXX's cockpit, the V-12 has been enlarged from 5998 to 6262 cc and features redesigned combustion chambers, a new crankcase, a low-backpressure exhaust, and revised cam profiles--all of which increase output from the Enzo's 651 horsepower to 800 (which converts to 789 SAE net) at 8500 rpm.

A new active aerodynamics system uses six computer-controlled actuators that, above 150 mph or so, open to redirect underbody airflow--lowering the car's drag while also increasing downforce by roughly 40 percent compared with the Enzo. Other enhancements include specially developed Brembo composite-ceramic brakes and a claimed 220-pound weight reduction (to just 2700 pounds). The result? "Although we don't have an official acceleration number yet," says project leader Giuseppe Petrotta, "the FXX can reach 60 mph in about 2.8 seconds--nearly as quick as a Ferrari F1.
