Mechanism
Rock 'n' Roller Coaster is fast because an LSM launch covers 0 to 57 mph in 2.8 seconds, and the Muppets retheme kept that clock.
Linear synchronous motors, not a chain, produce the speed. RCDB says 57 mph and the 2.8-second launch, plus 80 feet, three inversions, and 5 g. Wikipedia says 57 mph (92 km/h) and the same 2.8 seconds.
Theme Park Insider says the Muppets version opened May 26, 2026, still at 57 mph with three inversions. The Aerosmith show is gone. The launch time is what the acceleration ranking uses. The 5 g figure is not turned into a second clock.
The Paris twin is Flight Force. A shorter world clock is Do-Dodonpa.

Rock 'n' Roller Coaster Starring The Muppets is the indoor launch coaster at Disney's Hollywood Studios. RCDB says 57 mph, 80 feet, 3,267.7 feet, three inversions, 5 g, and an LSM launch from 0 to 57 mph in 2.8 seconds. Wikipedia says 57 mph (92 km/h) and the same 2.8-second clock. Theme Park Insider says the Muppets retheme opened May 26, 2026, and that the coaster still reaches 57 mph with three inversions. The ride-speed rank is 57 mph. The launch-time rank is 2.8 seconds.
The Aerosmith show is gone. The launch hardware those pages describe is the figure that stayed. Paris's twin is now Avengers Assemble: Flight Force, with the same 2.8-second clock, and it is a separate row. The list does not divide 57 mph by 2.8 seconds and store a g.
