Esses

Esses are a series of connected turns on a race track that curve left and right in sequence, creating an "S" shape when viewed from above.

These alternating curves are among the most challenging sections on any race track because drivers must quickly change direction while maintaining speed. As the car goes through the first turn, it leans one way, then immediately must lean the opposite direction for the next turn. This rapid weight shifting tests both the driver's skill and the car's handling capabilities.

What makes esses particularly tricky is that drivers cannot take the perfect racing line through each individual turn. Instead, they must find a compromise line that flows smoothly through the entire sequence. Taking the ideal path through the first turn might put the car in a terrible position for the second turn, costing valuable time.

Smooth steering inputs are critical when navigating esses. Jerky or aggressive movements can upset the car's balance, causing it to slide or spin. Professional drivers practice these sections extensively to develop the precise touch needed to maintain momentum while transitioning between turns.

Some famous examples of esses include the high-speed sequence at Suzuka International Racing Course in Japan and the challenging esses at Road Atlanta in the United States. These sections often separate experienced drivers from beginners, as they require excellent car control and racecraft.

For spectators, esses provide exciting viewing opportunities because they often see dramatic battles between drivers and occasional mistakes that can dramatically change race positions. The visual appeal of cars flowing through these serpentine sections also makes them popular camera locations during television broadcasts.
