The FXX is a limited-edition, $1.8 million track car that Ferrari is offering to about thirty current owners--called Client Test Drivers and selected via an application process--giving them the opportunity to play Michael Schumacher (although perhaps in his pre-2005 form). This is Ferrari's fastest-ever production car, using an 800-plus-hp, 6.2-liter version of the Enzo's 660-hp, 6.0-liter V-12. With 40 percent more downforce than an Enzo and slick Bridgestone tires, the owners likely will need Ferrari's included driver training before embarking on the fourteen-event track-day series that is also part of the FXX package. The breathed-on Enzo is not h0mologated for street use, by the way. According to Ferrari, FXX owners ''will actually be joining Team Ferrari.'' Well, um, yes, we suppose so, although we don't know of many billionaires whose driving skills match those of Scuderia Ferrari's current drivers, including Schumacher, Rubens Barrichello, and Luca Badoer.
