The New Revolution (formerly known as Revolution, Great American Revolution and La Revolución) is a steel roller coaster located at Six Flags Magic Mountain in Valencia, California. Manufactured by Anton Schwarzkopf and designed by Werner Stengel, the roller coaster opened to the public on May 8, 1976. The New Revolution is the world's first modern roller coaster to feature a vertical loop and has been recognized for that accomplishment by American Coaster Enthusiasts (ACE), who awarded the roller coaster its Coaster Landmark status. However, there were earlier examples of roller coasters with a full vertical loop, such as the steel roller coaster called "Looping the Loop" in Parque Japonés in Buenos Aires, which operated from 1911 to 1930.The coaster was named after the American Revolution in celebration of the country's Bicentennial. Unlike many of the previous looping roller coasters in the 19th and early-20th centuries which attempted circular loops, Revolution's success was dependent on a clothoid-shaped vertical loop – a first in the industry. In 2016, the coaster received a makeover for its 40th anniversary that included new trains with lap bars and an optional virtual reality experience for riders. The New Revolution soft-launched to season pass holders on March 26, 2016, and opened to the general public on April 21, 2016.
