A "Hot Rod" is a modified car, typically an older model, that has been enhanced for speed and performance. These vehicles often feature powerful engines, lightweight bodies, and custom designs. Hot rods are popular in car culture, especially among enthusiasts who enjoy racing and showcasing their unique builds. The term originated in the United States during the 1930s and 1940s, when car enthusiasts began to modify their vehicles for drag racing. Hot rods often incorporate elements from classic cars, muscle cars, and custom builds, making them a symbol of automotive creativity and freedom.
