^The planning documents say:
Noise from the planned new coaster was modelled based on a similar one located at Thorpe Park. The Thorpe Park ride, “Saw” is the same type and manufacturer as the proposed ride, including a “beyond vertical” drop.
It's a little unclear, just because that "beyond vertical drop" bit is included. I'm not saying that it isn't a Gerstlauer, because 90% of that sentence tells me that it is. But then it's iffy, because this one clearly doesn't have a beyond-vertical drop.
Granted, it could just be a poorly-constructed sentence, where the "beyond vertical drop" is only in reference to Saw. Can't blame anyone for overthinking it though, because it isn't very clear.
