Opened in 1962, Sandown International Raceway made an immediate splash when it brought in the world’s premier drivers for the Sandown International Cup that March. The track held its original layout until 1984, when an infield section was added to meet minimum track length requirements to host World Sportscar Championship events; eventually, that layout evolved into the current 13-turn, 1.928-mile (3.104 km) course used today.
