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.
Construction began in 1971 and the circuit officially opened on 8 April 1972. It was originally 8.4 m wide and 3.000 km long. In 1992, a chicane was added, making it 3.021 km long. In 1996, a fast bend replaced a sharp corner at the end of the pit straight, which shortened the length to 3.000 to 2.976 km and 3.021 to 2.997 km respectively. Fiorano has a wide range of corner types, with corner diameters between 370 and 13.71 m. Thus, Ferrari is able to simulate corner and track types of other Grand Prix circuits. As with Suzuka, it is a figure-of-eight course.
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, as is the Assetto Fiorano track package of the Ferrari SF90 Stradale and the Ferrari 296 GTB.
