Racing Line Lab · physics-simulation estimates

Circuit of The Americas,
re-solved live.

Austin, Texas · 5.49 km · 3.41 mi · counterclockwise

Open Circuit of The Americas in the Racing Line Lab and the browser re-solves the speed profile on the computed racing line as you change bike class, mass, power and grip. Every figure below is a simulation estimate on OpenStreetMap-derived geometry — not a measured lap.

The map and these reference laps are free in the Lab; live solving on this track unlocks with the $29 lifetime all-tracks pass.
