Circuit of The Americas
5487 m · 23 corners · reference lap 2:50.42 (supersport 600, simulation estimate)
The reference below is a minimum-time line solved from this track's geometry with a quasi-steady-state motorcycle model. It is a ceiling under ideal assumptions — use it to see where your headroom lives, then drop your own session file to measure yours.
Three places to look first
Biggest braking event
Turn 13 (T13): 131.3 → 44.0 km/h over 3.0 m. Brake-point consistency here is worth more than anywhere else on the lap.
Commitment corner
Turn 10 (T10): reference minimum 128.0 km/h. Fast corners punish hesitation — min-speed spread here is the classic amateur time leak.
Slowest corner
Turn 16: 31.2 km/h minimum. Exit drive from here sets the following straight — spread on the exit costs the whole next sector.
