Vortex is a steel stand-up roller coaster at Carowinds that was built during the last year before Paramount bought the park in the year 1992. This ride, which was unusual at its time, officially opened on March 14, 1992, on the former site of the Carolina Speedway miniature car ride. Vortex was Bolliger & Mabillard's 3rd coaster and contains a loop and a corkscrew element in its small circuit. Vortex was repainted for the 2011 season with red track and gray supports, quite similar to the park's Intimidator coaster. Debuting with Iron Wolf at Six Flags Great America and Vortex at California's Great America in the 1990s, Vortex was one of the first of a new generation of more developed stand up coasters than what had been introduced in the 1980s.
