The term "apex" likely originated from the geometric concept of the vertex, the point of intersection of two lines or curves. In racing, it refers to the ideal point on the inside of a turn that a driver should aim for to optimize their trajectory.
Correctly hitting the apex allows the driver to straighten out the corner as much as possible, reducing the amount of steering input required and allowing for earlier application of throttle. Missing the apex can result in a compromised exit, slower speed, or even running wide off the track.
Different track conditions and racing situations may require adjusting the apex point, but the basic principle of optimizing the racing line remains the same.
Key facts
- The apex is the innermost point of a corner.
- Hitting the apex optimizes the racing line.
- It allows for earlier throttle application.
- Missing the apex can compromise exit speed.
- Apex can be adjusted for changing conditions
