Line (racing)

From Wikipedia, the free encyclopedia

In racing sports, the ideal line is the path that a competitor takes through a race course, the line that allows the competitor to travel at the highest average speed. The ideal line is often used in motorsports, though other racing sports such as skiing and bicycling have similar concepts of an ideal line.

When analyzing a single corner, the optimum line is one that minimizes the time spent in the corner and maximizes the speed as the vehicle leaves the corner.

The apex is the point in the turn where the vehicle runs closest to the inside edge of the track. Hitting the apex allows the vehicle to take the straightest line and maintain the highest speed through that specific corner.

Also in drifting, one should aim the front of their car towards the apex to allow for a high-angle drift. If one is engaged in a tough battle, high-angle drifting with the front of the car facing the apex will block off the opponent chasing behind them.

The line taken is actually to minimise the amount of sidewards roll the car experiences. Basically the lesser wheel turn will translate into a lesser roll(compared to turning more), lesser tire wear against the ground especially in the wheel of the drive train.
