Today

There is still a vibrant Hot Rod culture worldwide, especially in the United States and Sweden. The hot rod community has now been subdivided into two main groups: hot rodders and street rodders. Hot rodders build their cars using a lot of original, old parts, and follow the styles that were popular from the 1940s through the 1960s. Street rodders build cars (or have them built for them) using, primarily, new parts.

Street rod builder Boyd Coddington currently stars in American Hot Rod, a documentary series on Discovery channel. One of his cars appeared in the music video of Gimme All Your Lovin’ by the rock band ZZ Top. The Discovery Channel airs several shows dealing with modern interpretations of kustom kulture such as Monster Garage, American Hot Rod, and Overhaulin'.

Juxtapoz Magazine, founded by the artist Robert Williams, has thrived as a recent extrapolation of kustom kulture art. It has also begun to garner respect as an exhibitor of contemporary artistic talent that transcends kustom kulture's bounds.

There is a contemporary movement of traditional hot rod builders, car clubs and artists who have returned to the roots of hot rodding as a lifestyle. This current traditional hot rod culture is exemplified in a whole new breed of traditional hot rod builders, artists and styles, as well as classic style car clubs like the Deacons, the Shifters, and the Dragoons. Events like Viva Las Vegas, and GreaseOrama showcase this return to traditional hot rods and the greaser lifestyle. Underground magazines like Garage, Rolls & Pleats, and BurnOut showcase this return to traditional hot rods by covering events and people around the world. There are number of independently released DVDs featuring this traditional hot rod revival with names such as Mad Fabricators, Hot Rod Surf ‘All Steel All Real’, and Hot Rod Havoc.

The culture is vibrant in Sweden where there are many automobile enthusiasts, also known as raggare. Meetings like Power Big Meet and clubs such as Wheels and Wings in Varberg, Sweden have established themselves in Swedish Hot Rod culture. Since there is very little "vintage tin" the hot rods in Sweden are generally made with a home made chassis (usually a Ford model T or A replica), with a Jaguar (or Volvo 240) rear axle, a small block V8, and fiberglass tub, but some have been built using for instance a Volvo Duett chassis. Because the Swedish regulations required a crash test even for custom-built passenger cars between 1969 and 1982 the Duett option was often used since it was considered a rebodied Duett rather than a new vehicle.

Hot Rod era

The Hot Rod era extended from 1930 to the beginning of the muscle car era (about 1965), reaching its height in about 1955. During this time, there was an adequate supply of what hot rodders called "vintage tin": junk cars manufactured prior to 1942 that could be had cheaply. Many of these had sound bodies and frames and had been junked for mechanical reasons, since the running gear of early cars was not durable. The typical hot rod was heavily modified, particularly by replacing the engine and transmission, and possibly other components, including brakes and steering. Certain engines, such as the flathead Ford V8, and the small block Chevrolet V8 were particularly popular as replacements because of their compact size, availability, customization and power. The early Hemi was popular in applications that required more power, such as drag racing. More recently, more unusual engines have become popular to use in hot rods, notably the Cadillac 500 and the Buick "NailHead".

Construction of a hot rod requires skills in mechanics, welding, and automotive paint and body work.

The "classic era" of hot rod construction ended around 1965, partly because the supply of vintage tin had diminished, but mostly because new cars were equipped for greater speed and power from the factory with little or no modification required.

Today, there are still a large number of hot-rodders and street-rodders. The Street Rod Nationals serves as a showplace for the majority of the hot-rodding and street-rodding world to display their cars and to find nearly any part needed to complete them.

Hot rod

Hot rods are typically American cars with large engines modified for linear speed. Nobody knows for sure the origin of the term "hot rod." One explanation is that the term is a contraction of "hot roadster," meaning a roadster that was modified for speed. Open roadsters were the cars of choice to modify because they were light. Hot Rod may also refer to the cam or pushrods inside the engine or other to the exposed frame rails of such an automobile. It was adopted in the 1930s or 1940s as the name of a car that had been "hopped up" by modifying the cam to achieve higher performance.
