Precision physics simulator of the narrowest street-circuit corridor in world motorsport. Test entry velocity, steering lock, and millimetric clearance to the 12th-century stone fortress.
Turn 8 of Baku City Circuit surrounds the UNESCO-listed 12th-century fortress walls of the Old City (Icherisheher). With an FIA regulation F1 car spanning exactly 200 cm (2.0 m) in width, a 7.6 m road width leaves virtually no margin for wheel lockup or corrective counter-steering.
Drivers must aggressively clip the inner left kerb at Turn 8 to open the entry angle into Turn 9. Clipping the kerb lifts the inside tires, momentarily reducing lateral grip and pitching the right rear toward the ancient stone masonry.
In 2019 Q2, Charles Leclerc locked his front-right tire on entry, producing immediate understeer directly into the castle chicane Tecpro barrier. The telemetry recorded just a 5 km/h entry overspeed, proving that millimetric errors result in total sector failure.
While Monaco's Fairmont Hairpin is narrower, it is tackled at under 50 km/h with high downforce. Baku's Castle Section is entered at over 150 km/h on a low-to-medium downforce aero configuration designed for the 2.2 km main straight, creating a severe trade-off between straight-line top speed and slow-corner mechanical grip.
The simulator projects an exact 4-corner bounding box of the F1 car (5.63 m long by 2.0 m wide) along the trajectory, computing continuous Euclidean distance vectors to the inner and outer spline boundaries of the Baku fortress wall.
Yes. Completing a sector run generates a comprehensive telemetry JSON file containing time-indexed timestamps, coordinates, lateral G forces, speeds, wall clearances, and flag statuses.
