1000 km Monza

Despite its title, the race has been run at shorter lengths (most notably in the late 1970s and early 1990s, before the demise of the World Sportscar Championship in 1992). The Coppa Intereuropa was first held in 1949[1] on a 6.3-km (3.9-mi) circuit. The race length was expanded to 1,000 km in 1954; in 1956, it was held on a 10-km (6.2-mi) circuit. The race was shortened and returned to the 6.3-km track the following year. In 1960 and 1961, it was part of the FIA GT Cup.

In 1963, the race was held as a three-hour event for production-based cars in the World Sportscar Championship before its expansion to 1,000 km in 1965. Until 1969, the full Monza circuit (including the banked oval) was used. To slow the cars, chicanes were installed in 1965 at the beginning of the second bank (the south curve) and in 1966 at the beginning of the other bank. A lap was 10.1 km long, for a total distance of 1,010 km (100 laps). From 1970 to 2008, the shorter Grand Prix circuit (about 5.8 km) was used for 173 laps.

• 1976 - The World Sportscar Championship was split into two series. The first, for production cars, was called the World Championship for Makes. The second, for prototype cars, was called the World Sports car Championship. The Monza race was eligible for the latter in 1976 and 1977.
