599 HGTE The Ferrari 599 GTB Fiorano HGTE (
HGTE being an abbreviation of
Handling
Gran
Turismo
Evoluzione) is an upgrade package for the 599 designed to improve the car's handling. It includes a modified set-up with stiffer springs and rear
anti-roll bar as well as new calibration settings for the Delphi
MagneRide magneto-rheological shock absorbers when the
manettino is at its sportier settings. The ride height has also been lowered, resulting in a low centre of gravity. The package also includes optimised tyres featuring a compound that offers improved grip. The car's electronic systems were also changed. The gearbox's shift times were faster in high-performance settings, while new engine software provided improved response. The exhaust was modified to produce a more marked and thrilling sound under hard usage while still delivering the right comfort levels at cruising speed. The exterior and interior were upgraded with more carbon fibre components and the car also included new 20-inch wheels.
599 GTO On 8 April 2010, Ferrari announced official details of the 599 GTO (for
Gran Turismo Omologato). The car was a road-legal version of the
599XX track day car and at the time Ferrari claimed that the 599 GTO was their fastest ever road car, able to lap the
Fiorano test circuit in 1 minute 24 seconds, one second faster than the
Ferrari Enzo. Its engine generated a power output of at 8,250 rpm and of torque at 6,500 rpm. The car has the multiple shift program for the gearbox from the 599XX along with the exhaust system. Ferrari claimed that the 599 GTO could accelerate from in under 3.3 seconds and has a top speed of over . Production was to be limited to 599 cars. Of these, approximately 125 were produced for the United States market. Ferrari has produced only two other models that used the GTO designation: the
1962 250 GTO and the
1984 288 GTO with the third being the 599 GTO. Unlike the previous GTOs however, the 599 GTO was not designed for homologation in any racing series.
599XX At the
2009 Geneva Motor Show, 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 behind the steering wheel replacing all analogue gauges, and 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 , a speed at which the car needed no additional downforce. With all such components, the car was reported to generate of downforce at and of downforce at . 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 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 in 2.9 seconds and attained a top speed of (redline limited top speed). 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 lap time ever recorded for a production-derived sports car. This time was later beaten by the
Pagani Zonda R in June 2010, which completed the lap in 6 minutes and 47.50 seconds.
599XX Evoluzione On November 10, 2011, the first images of the 599XX Evoluzione 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 Evoluzione in preparation for the 2011
Bologna Motor Show. The 599XX Evoluzione weighed less than the standard 599XX and the engine had slightly improved peak power of and of torque. One of the key features of the Evoluzione is its active rear wing which can adjust automatically to provide increased cornering performance. ==Special variants==
