Hot rods are custom-built cars that emphasize speed and performance, often featuring modified engines and unique designs. Originating in the United States during the 1930s, these vehicles became symbols of American car culture, showcasing creativity and individuality among enthusiasts. Typically based on older models, hot rods are often stripped down to reduce weight and enhance power. They are frequently seen at car shows and drag races, where owners display their craftsmanship and compete for speed. The hot rod community celebrates innovation and a shared passion for automotive excellence.
