Vallelunga Circuit

From 1963 the circuit held the Rome Grand Prix, and in 1967 a new loop was added when the track became the property of the Automobile Club d'Italia (ACI). Further refurbishment was undertaken in 1971. The track is named for the famous Italian racing driver Piero Taruffi. In August 2004 work started on a extension to the track, bringing the track up to its current length. The new configuration has received homologation from the FIA as a test circuit, being used by various Formula One teams. The circuit has also hosted the 6 Hours of Vallelunga endurance event. The track is also used by ACI for public driving safety training courses and, in autumn of each year, hosts a vast flea-market specialising mainly in vintage automotive spare parts. The circuit is home to simulation software developers Kunos Simulazioni, who occupy a pit garage as an office. ==Events==
