Lingotto is a building complex on Via Nizza in Turin, Italy. It once housed a car factory built by Italian automotive company Fiat and today houses the administrative headquarters of the manufacturer and a multipurpose centre projected by architect Renzo Piano.

Construction of the complex started in 1916 and it was inaugurated in 1923. The design by the young architect Giacomo Matté-Trucco, was unusual in that it had five floors, with raw materials going in at the ground floor, and cars built on a line that went up through the building. Finished cars emerged at rooftop level to go onto the 1.5km long^[1] test track. The construction was carried out by the company of G A Porcheddu. It was the largest car factory in the world at that time. For its time, the Lingotto building was avant-garde, influential and impressive—Le Corbusier called it "one of the most impressive sights in industry", and "a guideline for town planning". 80 different models of car were produced there in its lifetime, including the Fiat Topolino of 1936.

By the late 1970s, the factory had become obsolete — having been superseded by the larger and more advanced Fiat Mirafiori factory — and a decision was made to finally close it in 1982. The closure of the plant led to much public debate about its future, and how to recover from industrial decline in general. An architectural competition was held, which was eventually awarded to Renzo Piano, who envisioned an exciting public space for the city. The old factory was restored into a modern complex, with concert halls, theatre, a convention centre, shopping arcades and a hotel. The eastern portion of the building is the headquarters of the Automotive Engineering faculty of the Polytechnic University of Turin. The work was completed in 1989. The track was retained, and can still be visited today on the top floor of the shopping mall and hotel.

Similar rooftop tests tracks exist, including; at Impéria in Nessonvaux in Belgium, and Palacio Chrysler in Buenos Aires, Argentina.^[2] From 1928^[3] to 1958, Impéria had a track over 1 km long which was built partially on top of the factory.

The Lingotto building is featured extensively in the Alberto Lattuada film Mafioso (1962).

The original Lingotto rooftop test track features briefly in the getaway sequence in the film The Italian Job (1969).

The building is also featured in the fourth episode of the 20th season of The Amazing Race, originally aired in the United States on March 11, 2012.

The building and test track was featured on the first episode of James May's Cars of the People.
