Nardò Ring

The Nardò Ring, originally known as Pista di prova di Nardò della Fiat when it was built in 1975, is a high speed test track located at more than 23 kilometres north-west of the town of Nardò, Italy, in the southern region of Apulia, in the Province of Lecce. It was acquired by Porsche Engineering in 2012 from its former owners, Prototipo SpA. Porsche now calls the site Nardò Technical Center.
