The Fiorano Circuit is a private racetrack owned by Ferrari for development and testing purposes. It is located in Fiorano Modenese, near the Italian town of Maranello.
Built in 1972, it was originally 8.4 metres (27.6 ft) wide and 3000 metres (1.86 miles) long. In 1992, a chicane was added making it 3021 metres (1.88 miles) long, then in 1996 a new renovated track was introduced (a fast bend to replace a sharp corner at the end of the pit straight) which shortened the total length by 24 metres (0.02 miles). The average F1 lap speed is over 160 km/h (99 mph) and the F1 top speed is 290 km/h (180 mph). As Fiorano is a testing track, it has a wide range of corner types, with corner diameters between 370 metres (1,213.9 ft) and 13.71 metres (45.0 ft). Thus Ferrari is able to simulate corner and track types of other Grand Prix circuits.
The track is equipped with telemetry sensors and a large skidpad for tyre testing. In 2001 an irrigation system using rain collected in eight cisterns was installed to simulate wet track conditions. When Scuderia Ferrari are testing a F1 car at the track, it is common to see Tifosi watching the test from the roadside, which is the closest point from which the track is viewable to the public.
Ferrari customers are allowed to test drive new cars at the Fiorano circuit. The Ferrari 599 GTB Fiorano is named after this track.
In the 16 years from the time the track opened until his death in 1988, Enzo Ferrari would either sit in his house which was located at the circuit and listen to, or actually sit track side and watch his beloved scarlet Formula One cars testing. Legend has it that this was actually the real reason that the "old man" had the circuit built, so he could enjoy his cars and his drivers without the presence of other F1 cars or the press. In reality Ferrari made the decision of building his own testing track when he realised that the Modena Autodrome could no longer serve this purpose.
