Hot rod


Hot rods are typically old, classic American cars with large engines modified for linear speed. The origin of the term "hot rod" is unclear. Some automotive historians say that the term originated with stolen vehicles being refitted with another engine and repainted. In the early days of automobile manufacturing there was no identical matching transmission, body frame, and engine numbers. It was possible to change engines and repaint the car or truck and in effect turn it into a different vehicle and thus it became near impossible to prove that the vehicle was stolen. The term "hot" was equivalent to being stolen. The term "rod" was equivalent to any motorized vehicle. Even today, the Ontario Ministry of the Environment in its vehicle emissions regulations, refers to a "hotrod" as any motorized vehicle that has a replacement engine differing from the factory original. Another possible origin includes replacement of the camshaft with a new ("hotter") version, sometimes known as a hot stick or hot rod.Roadsters were the cars of choice because they were light, easy to modify, and inexpensive. The term became commonplace in the 1930s or 1940s as the name of a car that had been "hopped up" by modifying the engine for higher performance. A term common in the early days was "gow job". This has fallen into disuse except with historians.

The term has broadened to apply to other items that are modified for a particular purpose, such as "hot-rodded amplifier".

The term seems first to have appeared in the late 1930s in southern California, where people raced modified cars on dry lake beds northeast of Los Angeles under the rules of the Southern California Timing Association (SCTA), among other groups. The activity increased in popularity after World War II, particularly in California, because many returning soldiers received technical training in the service. Many cars were prepared by bootleggers in response to Prohibition to enable them to avoid revenue agents ("Revenooers"); some police vehicles were also modified in response.

The first hot rods were old cars (most often Fords, typically Model Ts, 1928–31 Model As, or 1932-34 Model Bs), modified to reduce weight. Typical modifications were removal of convertible tops, hoods, bumpers, windshields, and/or fenders; channeling the body; and modifying the engine by tuning and/or replacing with a more powerful type. Speedster was a common name for the modified car. Wheels and tires were changed for improved traction and handling. "Hot rod" was sometimes a term used in the 1950s as a derogatory term for any car that did not fit into the mainstream. Hot rodders' modifications were considered to improve the appearance as well, leading to show cars in the 1960s replicating these same modifications along with a distinctive paint job.
