Baja Bug
A Baja Bug is an original Volkswagen Beetle modified as an all-terrain vehicle to operate off-road, although other versions of air-cooled Volkswagens are sometimes modified as well. Baja bugs often race in off-road desert races such as the Baja 1000. There are different classes for bugs, namely class 11, class 5 1600, and class 5 unlimited. According to desert racing association Score International, class 11 is a stock VW beetle with modifications limited to ground clearance and strength. Class 5 1600 rules state that a 1600 cc VW engine must be used and the car must have the exterior appearance of a "Baja bug" with body modification limited to whatever cutting is needed to install a consumer baja kit. Class 5 unlimited is any four-cylinder VW-style engine, and it must have Baja-style fenders and side panels, and VW-style suspension.. Another version of Baja Bug is Old Fusca, used for dirt racing in Paraná, Brazil. They are equipped with the AP engine from the early Volkswagen Golf generations, and can be fed by carburetor or electronic injection.
History
Baja Bugs originated in Southern California in the late 1960s as an inexpensive answer to the successful Volkswagen-based dune buggies of the mid-1960s, especially the Meyers Manx.The building of the first Baja Bug is generally credited to Gary Emory, circa 1968. Gary and his hot rodder father, Neil Emory, built the car in the bodyshop at the Chick Iverson Volkswagen dealership in Newport Beach, California; Gary worked in the parts department there after leaving school and Neil was working in the bodyshop.
The first Baja Bug in racing is credited to Dave Deal, the Californian cartoonist, in the Mexican 1000 of 1968 in Baja California.
The first fiberglass Baja kit was not introduced until 1969 by the Miller-Havens company. The original "Bugeye" kit by Miller-Havens Enterprises was widely copied. Drino Miller estimated that at least 8 of the original 10 kits sold were "splashed". Miller-Havens modified the rear panels of the original Bugeye kit in mid-1971 to add a longer engine cowl and longer rear fenders that original VW Bug rear lights could be mounted to. It was this 1971 kit that inspired the Tamiya Sand Scorcher radio-controlled Baja Bug. The 1971 update was also due to updated regulations in California regarding engine coverage.
In many US states and other countries, the headlight spacing of the Bugeye kits was illegal - the headlights were close together in the front panel, similar to early Land Rovers. In mid-1972, Don Rountree of the Sandwinder Company/R&H Fiberglass launched the first wide-eye Baja bug kit - the headlights of the Sandwinder kit were mounted in the front fenders and the rear panels were much longer. The Sandwinder one-piece flip front was then used on the majority of Baja racers cars.
In the early days before fiberglass body panels became available, enthusiasts and racers simply made their own modifications to both the body and mechanicals of a stock VW to develop a machine suited to harsh, off-road environments. The metal fenders and front and rear aprons of the car would be partially cut away to allow more room for ground clearance and suspension travel. This came to be known as a "Cut Baja", but at the time these cars were referred to as "Choppers" in magazines. As much as California gained the reputation for inventing the Baja Bug, Choppers/Cut Bajas were also widespread in Michigan from the early 1960s; they were called "Muckers" in Michigan. More power was attained by fitting dual port heads and modifying fuel injection systems from Volkswagen Type 3 engines to work on the Type 1 Beetle engine. Some installed the larger, 1.7, 1.8, and 2.0 Volkswagen Type 4 or Porsche 914 engine. Corvair engine transplants were another common way of achieving a large power hike.
