No Roller Coaster Has an 85° Drop — The Steepest Is 121°

Zero roller coasters have an 85° angle of descent. That angle would be "beyond vertical" — physically impossible for a conventional coaster train on rails (85° from horizontal = 5° from vertical; 90° = straight down).

The Steepest Real Drops

Conventional "Steepest" (Vertical = 90°)

• Oblivion (Alton Towers, UK): 87.5° (Dive Coaster, 1998) — first "vertical" drop.
• SheiKra / Griffon / Valravn (Busch/SeaWorld): 90° true vertical (Dive Coasters).
• Most hyper/giga coasters: 60–85° (e.g., Fury 325: 81°, Steel Vengeance: 90°? No, 90° is dive. Steel Vengeance 90°? Actually 90° is vertical. Most steep non-dive: ~80-85°).

Why 85° Doesn't Exist as a Record

It's an awkward angle — steeper than typical lifts (30–45°), shallower than vertical drops (90°+). No manufacturer targets it. The record progression jumped from ~80° (1990s) to 90° (Dive Coasters, 1998) to >90° (Euro-Fighter, 2008+).

So: 85°? No coaster. 121°? World record (Takabisha / TMNT).
