The Flash: Vertical Velocity, Steel roller coaster at Six Flags Great America in Gurnee, US.
The Flash: Vertical Velocity is a steel-supported coaster featuring two vertical towers extending 186 feet and rapid linear launches along its route. The seven-car train carries around 28 riders per cycle through a U-shaped track with multiple quick direction changes.
This coaster opened in 2001 under the name Vertical Velocity and was a major new addition to the park at that time. In 2022, red support beams were added and the attraction was transformed to reflect The Flash superhero theme.
The rebranding connects this ride to the DC Comics universe, with The Flash superhero elements visible throughout the station and queue area. This themed approach shapes how visitors experience the attraction from arrival to departure.
Riders must be between 54 and 80 inches tall to board, and loose items should be secured before the ride begins. The ride operates year-round during park hours, and wait times tend to be shortest in the early morning.
This coaster uses linear induction motors to propel riders through multiple passes at the station, enabling extreme acceleration in seconds. This system creates an unusual ride experience with sudden speed changes that many first-time visitors find surprising.
