Shark Fin

A Shark Fin is a vertical aerodynamic panel that extends from the engine cover or cockpit to the rear of a race car, resembling the dorsal fin of a shark.

This aerodynamic device primarily improves stability during cornering and prevents the car from becoming unstable or airborne during spins. The fin works like a weather vane, counteracting sideways forces and helping the car maintain its intended direction, especially in high-speed turns.

Shark Fins became prominent in Formula 1 during the late 2000s and are common in endurance racing categories like Le Mans Prototypes. Beyond their aerodynamic benefits, these fins provide valuable space for team sponsor logos. Though effective for stability, some critics consider them visually unappealing on otherwise sleek race cars.
