Racing lines in karting

In karting, the racing line refers to the path on the track that a driver takes to complete a lap in the shortest amount of time. The clean racing line refers to the ideal path on the track that a driver should take to achieve maximum speed and efficiency while driving.

The clean racing line usually involves starting from the outside of the track, then moving towards the inside of the track on the approach to a corner. The driver then turns in towards the apex of the corner before accelerating out of the corner towards the next one.

Taking the clean racing line allows the driver to maintain maximum speed through the corners and minimize the distance traveled around the track, which leads to faster lap times. It also allows for safer and more controlled driving as it reduces the risk of collisions with other drivers.

In competitive kart racing, the ability to take the clean racing line consistently is a critical skill that separates the top drivers from the rest of the field.

When approaching a corner on a track, a driver's goal is to take the shortest possible path while maintaining the highest speed. To achieve this, the driver must take a line that follows a smooth and continuous curve through the corner. This line is known as the racing line.

The clean racing line typically involves three phases:

Braking Zone: The driver starts by braking in a straight line, usually in a straight section of the track before the corner, to scrub off some speed. Then the driver moves towards the outside of the track to set up for the corner.

Apex: The apex is the point where the driver's kart is closest to the inside of the corner. To reach the apex, the driver will begin to turn in towards the inside of the track while releasing the brakes, and will then steer the kart around the corner, following a smooth and continuous arc.

Exit: After the apex, the driver gradually accelerates out of the corner, taking the shortest possible path towards the next corner, while avoiding any kerbs or obstacles that could upset the kart's balance.

It's worth noting that the racing line is not always the same for every corner on a track. The ideal line will depend on factors such as the layout of the track, the condition of the tyres and the weather conditions. A good driver will be able to adjust their line to suit the conditions and achieve the fastest lap times.
