The 599 GTB Fiorano (internal code F139) is an Italian grand tourer produced by Ferrari. It is the brand's 2-seat Gran Turismo flagship model, replacing the 575 M Maranello in 2006 as a 2007 model. The 599 GTB debuted at the Geneva Motor Show on February 28, 2006. Styling of the 599 GTB was handled by Pininfarina, under the direction of Ferrari stylist, Frank Stephenson. It is named for its total engine displacement (5999 cc), Gran Turismo Berlinetta nature, and the Fiorano Circuit test track used by Ferrari. Tipo F133F 6.0 L (5999 cc) V12 engine produces a maximum 620 PS (456 kW; 612 hp), making it the most-powerful series production Ferrari road car. Its 608 N·m (448 ft·lbf) of torque will also be a high for Ferrari's GT cars. Most of the modifications to the engine were done to allow it to fit in the Fiorano's engine bay (the original Enzo version could be taller as it would not block forward vision due to its mid-mounted position). The company claims a top speed in excess of 330 km/h (205 mph), 0-100 km/h (62 mph) in 3.7 seconds, and 11.0 seconds to 200 km/h (124 mph).A traditional 6-speed manual transmission as well as Ferrari's 6-speed sequential manual gearbox called 'F1 SuperFast' is offered. The e-diff active differential from the F430 is not used. However, the Manettino concept first seen in the F430 also appears in this car. Ferrari sourced the Delphi Corporation's MagneRide semi-active magneto rheological dampers. Reviewers of the car have mentioned that the MagneRide suspension gives the 599 a very comfortable ride but allows it to handle well at the same time.
The Fiorano also sees the debut of Ferrari's new traction control system, called F1-Trac. Reportedly tuned using inputs from 7-time Formula 1 World Champion Michael Schumacher, the system supposedly allows a competent driver to lap the Fiorano test track at just 1 second behind Michael's time.
