A fin on a vehicle is a protruding feature often seen on the body of a car, particularly on older models or sports cars. It is designed to improve aerodynamics by reducing air resistance and increasing stability at higher speeds. Fins can also be purely decorative, adding a distinctive look to the vehicle. They are typically found along the rear end of the car, on the sides or back, and were more common in the mid-20th century, especially in the designs of American cars.
