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).
