An inverted roller coaster is a roller coaster in which the train runs under the track with the seats directly attached to the wheel carriage. This latter attribute is what sets it apart from the older suspended coaster, which runs under the track, but swings via a pivoting bar attached to the wheel carriage. The coaster type's inverted orientation, where the passengers' legs are exposed, distinguishes it from a traditional roller coaster, where only the passengers' upper body parts, including the arms, are exposed.
The inverted coaster was pioneered by the Swiss roller coaster designers Bolliger & Mabillard in the early 1990s. The first installation came at Six Flags Great America in 1992.
Other roller coaster manufacturers followed in the footsteps of Bolliger & Mabillard and began working on their own inverted coaster designs, including Vekoma, Intamin and other smaller companies. Intamin has few designs classified as inverted coasters, although they do install inverted coaster trains on some of their launched designs. Vekoma, on the other hand, usually mass-produces the same design ] with 41 identical coasters – and a few variations of that design – installed around the world. Also, in recent years, Vekoma has become the first manufacturer to install a family-friendly inverted roller coaster. Giovanola also has a single inverted coaster operating.
The inversions usually includes a vertical loop, zero-g roll, Immelmann loop, cobra roll, and a corkscrew.
