At the 2009 Geneva Motor Show,[3] Ferrari unveiled the track-only iteration of the 599 GTB, dubbed the 599XX. Designed by Ferrari's Formula-one engineers, the car has many changes over the standard car in order to make it more nimble and responsive on a race track.

Specifications

Exterior enhancements included two winglets on the C-pillars for improved downforce, a vented bonnet for improved engine cooling, darkened lexan tail lamps, a carbon fibre 'ducktail' rear spoiler aiding further in downforce, a large rear diffuser for improved under body airflow, tow hooks at the front and rear, additional ducts for improved cooling, a minimalist race interior with racing bucket seats along with an LCD display behind the steering wheel replacing all analogue gauges equipped with a roll-cage and lexan sliding windows. The car also has two fans that were located in the trunk and worked to keep the car on the ground and stopped working at speeds up to 249 km/h (155 mph), a speed at which the car needed no additional downforce. With all such components, the car was reported to generate 280 kg (617 lb) of downforce at 200 km/h (124 mph) and 630 kg (1,389 lb) of downforce at 299 km/h (186 mph). The air conditioning system was retained for added driver comfort. The car had nine traction and stability control modes, all controlled from the manettino dial on the steering wheel. The car was equipped with F1 inspired carbon ceramic brakes with crossed drilled rotors and a new race exhaust system. The rev limiter was raised to 9,000 rpm, with the engine rated at 730 PS (537 kW; 720 hp) at 9,000 rpm. Weight was reduced by reducing the weight of the engine components such as a new carbon fibre intake manifold and graphite coated pistons along with a lightweight crankshaft, as well as through the use of composite materials and the use of carbon fibre body parts. A new gearbox was introduced to cut overall gear change time to 60 milliseconds, holding the upward or downward shift paddle for longer resulted in multiple shifts that improved gearing time. The car also included 29/67 R19 front and 31/71 R19 rear racing slicks with 19 × 11J wheels at the front and 19 × 12J at the rear. The 599XX was capable of accelerating from 0–100 km/h (0–62 mph) in 2.9 seconds and attained a top speed of 315 km/h (196 mph) (redline limited top speed). The 599XX had a price of $1.5 million when it debuted.[4]

Records

At the 2010 Beijing International Auto Show, Ferrari announced that the 599XX had completed the Nordschleife circuit at the Nürburgring in a time of 6 minutes and 58.16 seconds – the fastest time ever recorded for a production-derived sports car.[5] This lap was later beaten by the Pagani Zonda R in June 2010, which had set a lap time of 6 minutes and 47.50 seconds.

599XX Evo

On November 10, 2011, the first images of the 599XX Evo surfaced, which had a radically restyled aero and exhaust package as well as electronic upgrades and Pirelli racing slicks. On 1 December 2011, Ferrari confirmed details for the 599XX Evo in preparation for the 2011 Bologna Motor Show.[6] The 599XX Evo weighed 35 kg (77 lb) less than the standard 599XX and the engine had slightly improved peak power of 750 PS (552 kW; 740 hp) and 700 N⋅m (516 lb⋅ft) of torque. One of the key features of the Evo is its active rear wing which can adjust automatically to provide increased cornering performance.
