This type of Roller Coaster is made by Bolliger & Mabillard. There is only one real world instance of this ride in the RCT series and that was Oblivion in Alton Towers (RCT1). As of 2006, this coaster type started it's new twister layout with Sheikra in Busch Gardens Tampa, also the trains became available in both 8 and 10 across seating; yet only one uses the ten across seating formation (Griffon in Virginia). As of 2007, the trains also come with a floorless option. Recently, Krake at Heide Park with 6-abrest seats.
