Track-out
Track-out is the point on a corner's exit where the car reaches the outside edge of the track as you unwind the steering.
Also called: track-out point, exit point
After the apex, you unwind the steering and let the car drift back toward the outside edge. The point where it reaches the edge, usually near the end of the exit curb, is track-out. Using all the road here lets you straighten the wheel sooner and accelerate harder.
A good track-out feels like the car flowing out naturally under acceleration, with the steering coming back to straight as you reach the edge. You should not have to fight it out there or hold it off the curb.
If you reach track-out with room to spare, you could have used more throttle earlier or a different line. If you run out of room and drop wheels off, you were too fast, apexed too early or applied throttle too aggressively. In that case, follow off-track recovery: keep it straight, slow down and rejoin safely.
Using all the track at exit maximizes acceleration onto the straight, while knowing your track-out keeps you from running off.
Simplified 90° corner. Real corners trade entry, mid-corner and exit speed differently; what follows the corner decides which matters most.
