Ferrari 599XX 2010

At the 2009 Geneva Motor Show,[2] 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.

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).
