In 1985, Giovanola and Intamin supplied Z-Force to Six Flags Great America/Hurricane Harbor.
It was the first coaster to feature 4 seats-across trains. Perhaps more importantly, the ride used a new distinctive track with a box spine. This new track was developed in-house at Giovanola by a team comprising two promising engineers: Walter Bolliger head of the amusement rides division and Claude Mabillard head of construction. Designed with the help of Werner Stengel, Z-Force featured a compact layout featuring a series of tight curved drops. Unlike most coasters at the time, banked turns were calculated around the heart-line, allowing for smoother transitions.
As part of Six Flags’ ride rotation policy which was prevalent then, Z-Force was moved to several other parks in the chain. In 1992, the coaster was relocated for a second time to Six Flags Magic Mountain and changed its name to Flashback. By then, the coaster was said to deliver a very rough and unpleasant ride experience. In addition, the very loud noise produced by the train was reported to be distracting to safeguards working in the close-by waterpark. By the late 1990s, Flashback was rarely operating during the season. Eventually, the ride was dismantled in 2007.
In 1986, Giovanola produced its own version of a popular ride type at the time: the stand-up coaster. Shockwave opened at Six Flags Magic Mountain reusing the thick box-track as well as the 4-across trains and foreshadows B&M classic looping coasters with little details like the pre-drop and a section of track threading inside the vertical loop. Six Flags also moved Shockwave across different venues. From 1993, the ride operated as Batman The Escape at Astroworld until the park was demolished in 2005.
In 1988 however, a change of management led Walter Bolliger and Claude Mabillard to leave Giovanola and start their own business. Setting their office still in Monthey nearby their former employers, the new eponymous company was initially expecting to work outside the amusement world. In fact, for their first project B&M designed a rotating platform for a panoramic restaurant located on top of the Berneuse mountain in Switzerland.
However, Six Flags Great America in Illinois offered one project after another, which eventually lured back B&M in the industry. (To begin with, Six Flags asked the new company to design new trains for Sarajevo Bobsled located at Six Flags Great Adventure in New Jersey. The corporation wanted to move the ride to Great America, but there was a capacity issue with the original cars. Using their direct knowledge of Giovanola’s Bobsleigh coaster model, B&M delivered new cars compatible with the existing track but with increased capacity.
Six Flags Great America was satisfied with what B&M delivered, so the park asked the new company to design a full-fledged roller coaster. However, because the two Swiss engineers were only getting started as their own firm, this posed several challenges. Finding a facility with high-standard manufacturing was necessary to supply the tracks and columns for the project. Eventually Clermont Steel Fabricators was chosen, as their work building the supports of Vortex at Kings Island was deemed impressive. B&M also needed to ensure the coaster’s track would comply with IP laws, so they made slight alterations to the box design they helped create at Giovanola. Iron Wolf, a stand-up coaster with 2 inversions, successfully debuted in 1990. The rest is history.
