The Nardò Ring (Pista di prova di Nardò della Fiat, built in 1975) is a high speed test track located at more than 20 kilometres (12 mi) north-west of the town of Nardò, Italy, in the southern region of Apulia, in the province of Lecce.
The track is 12.5 kilometres (7.8 mi) long and is round, has four lanes for cars and motorcycles totaling 16 metres (52 ft) in width and has a separate inner ring for trucks at a width of 9 metres (30 ft). In the cars/motorcycle ring the lanes are banked at such a degree that a driver in the outer most lane doesn’t need to turn the wheel while driving at speeds of up to 240 km/h (149 mph). In essence, at the so-called neutral speed which is different for the four lanes, one can drive as if in a straight lane. However extremely fast cars still require the steering wheel to be turned when going faster than the maximum neutral speed. For example the Koenigsegg CCR which set a speed record for a production car at the Nardò Ring did so with the steering wheel at a 30° angle. This speed record has since been beaten by the Bugatti Veyron at Volkswagen Group’s private Ehra-Lessien straight line test track in Germany, and hence the CCR only holds the speed record for the Nardò Ring.
