A dune buggy is a recreational vehicle with large wheels, and wide tires, designed for use on sand dunes or beaches. The design is usually a modified vehicle with a modified engine mounted on an open chassis. The modifications usually attempt to increase the power to weight ratio by either lightening the vehicle or increasing engine power or both. They are also often referred to as air buggies, and those with an open frame chassis are called sandrails.

A similar, more recent generation of off road vehicle, often similar in appearance to a sand rail but designed for different use, is the "off road go kart". It should be noted that the difference between a dune buggy or go kart and an "off road" buggy or kart is sometimes nothing more than the type of tires fitted -sand tires or all terrain tires - but "off road" go karts and buggies are a rapidly developing category of their own.

Dune buggies are usually created using two to three different methods.

The first involves alteration of an existing vehicle, most notable the older Volkswagen Type One (Beetle, or Bug). The Beetle was preferred for a variety of reasons. Most notable are the rear mounted engine, which with removal of bodywork transfers a high proportion of the weight to the rear drive wheels for extra traction; the engine is air cooled, simplifying engine modification, and the absence of a radiator, eliminating a source of failure; the low price; robustness of the front suspension; and the sizable quantity of spare parts from other VW Beetles and Type 2 buses. Corvair engines are also a popular upgrade to a 6 cylinder and sometimes turbo with up to 180 horsepower. For example, one such conversion was a 1970 Manx 2 on a 1961 VW chassis. It was fitted with a 180 HP turbocharged Corvair engine, with reverse rotation, mated to a VW transaxle.

The second method involves construction of a vehicle frame from steel tubing formed and welded together. The advantage of this method is the fabricator can change fundamental parts of the vehicle (usually the suspension and adding a built-in roll cage). Buggies of this type are called sandrails because of the rail frame. Rails, as with the VW Bug, often have the engine located behind the driver. Sizes can vary from a small engined one seat size to a 4 seat, 8+ cylinder sized vehicle. Sandrails can have panels or custom shaped body coverings over the rails and tubing that comprise the vehicle, though many are left bare.

The third is only a temporary fix. These dune buggies represent mixes of the above two design philosophies, typically after a converted vehicle sustains damage from age, hard use, or accidents and spare parts are not available or affordable. This type of creation is called The Boston-Murphy style.

Initially dune buggies were designed for navigating desert or beaches (hence the word "dune"). However, dune buggies have become more diversified in terms of the terrain they can handle and are being built for more generic off road tasks, such as CORR / SCORE indoor track racing. Some are even built for and used as on-road vehicles. Typically the function is determined before the buggy is created in order to maximize the comfort or abilities of the vehicle.

Although dune buggies can be bought (as a kit), many drivers make their own. This is done by separately buying chassis, engine, tires, steering wheel, and axles. Some builders make their own chassis, which creates a special, customized vehicle.

A 1961 or later Volkswagen sedan is the preferred donor to create a Dune Buggy. The VW Type 2, Type 3 and Type 4 do not make good donor cars, however the engine, transaxle, wheels, and instruments can be used from these models.

Other parts that can be salvaged from a donor VW for use in a Dune Buggy include the front axle and suspension, frame, pedal assembly, shock absorbers, seats, battery, fuel tank (1961 or later), steering column, brakes, instruments and switches, windshield wiper, horn and emergency flasher unit.
