Baja Bug
From Wikipedia, the free encyclopedia
The term Baja Bug generally refers to a Volkswagen Beetle modified to operate on sand dunes and beaches, although other versions of air-cooled Volkswagens are sometimes modified as well.
Baja Bugs originated in Southern California in the early 1970s as an inexpensive answer to the successful, Volkswagen-based dune buggies of the mid-1960s, especially the Meyers Manx.

[edit] Why the Beetle?
The Beetle was popular in less-developed areas of the world because of its rear-mounted air-cooled engine, flat floorpan, and rugged torsion bar suspension. In fact, advertising of the period touted the fact that the Beetle was so watertight that it floated. Those same attributes made the Beetle the perfect choice for the basis of an off-road vehicle as evidenced by the car's success both then and now in the Baja 1000 off-road race.
[edit] Conversion
Basic modifications are simple. A lightweight, shortened fiberglass front body panel is fitted after the sheetmetal from the trunklid edge forward and rear engine hood rearward is removed. The rear treatment leaves the engine totally exposed to aid in cooling. A tubular steel cage front and rear bumper is fitted to the body and floorpan for protection of engine and occupants. Shortened fiberglass fenders both front and rear meant removal of the Beetle's distinctive running boards and the likely addition of more tubular steel parts in their place, (side bars). The adjustable torsion bar front and rear suspension standard on the Beetle, allows the ride height to be raised to make clearance for larger heavy-duty off-road tires and wheels. The taller sidewall tires provide more flexible ride comfort and rocky road ground clearance. The Beetle suspension "stops" can be moved to allow more suspension travel. Longer shock absorbers for the increase in suspension travel, provide more dampening control over bumps giving more driver control and comfort.
[edit] The Baja Bug today
Though Baja Bugs have been greatly supplanted in recent years by tube-framed, purpose-built buggies known as sand rails, due to the slowly dwindling supply of suitable donor cars, they remain a popular choice in desert regions as few beaches in the US are open to vehicular traffic. Many are fitted with highly modified Volkswagen engines and a few homebuilt hybrids have Ford Pinto engine, Chevrolet Corvair, Porsche, Mazda or even Subaru engines. Customized roadgoing Baja Bugs remain fairly popular as well.
[edit] Types of Baja Bug
Many types of Baja Bug exist however these fall into three main categories. These include 'Racing Class', 'Trailer Queen' and hybrid of the two being called 'Daily Driver'.
The racing Class Baja's are often referred to by enthusiasts as Class 5 and have sponsor racing decals and a characteristic three number race number clearly marked on the sides, the roof and front. These are most common in North and Central America in dune and desert racing. Rarely are these registered on the road as they usually have very little of the original VW pan and body and generally consist of a tube frame with racing style seats, high horsepower engine and very sturdy transaxle and suspension modifications expanding the track to avoid roll and increase ride height.
The Trailer Queen Baja is a fully engineered off-road Baja that may be registered and used on road but rarely leaves the comfort or a garage and mirror finished floors. This style of Baja would never have been in contact with the elements and is primarily used for the display of off-road automotive parts at car shows. The vehicle is fully functional and may be a mixture or Type 5 and Daily Driver modifications however the paint, tread nodes and chromed exhaust manifolds suggest this vehicle is rarely started and generally towed from location to location.
Daily Driver's are the most common form of Baja vehicle. These are always registered an as suggested by the name driven on a regular basis. That is they can also compete and be shown but are regularly used off-road as well as on. These vehicles are generally low budget with simple modifications but many excellent examples exist that are also driven on a regular basis. Daily drivers are capable of traversing most places 4x4 off-road vehicles are seen due to their light weight, reliable engine and steep approach and exit angles. Daily drivers can negotiate sand, mud and dirt terrain effectively however are dangerous in snow and ice conditions due to the large tyre size to vehicle weight.
