and drew much attention, it proved too expensive to be profitable; ultimately only 12 kits of the monocoque Manx were produced. Meyers and a friend (both amateur racers) broke by over four hours the Ensenada – La Paz run's record of 39 hours, until then held by a pro racer. According to James Hale, compiler of the Dune Buggy Handbook, this feat ushered in an era of Meyers Manx "domination in off-road events ... and the formation of NORRA (National Off-Road Racing Association)". B. F. Meyers & Co. The commercially manufactured Meyers Manx Mk I featured an open-wheeled fiberglass bodyshell, coupled with the Volkswagen Beetle H4 flat-four engine (1.2 L, 1.3 L, 1.5 L and 1.6 L, in different models) and a modified, RR-layout Beetle frame. It is a small car, with a wheelbase 14 inches (36.2 cm) shorter than a Beetle automobile for lightness and better maneuverability. For this reason, the car is capable of very quick acceleration and good off-road performance, despite not being four-wheel drive. The usually street-legal car redefined and filled a recreational and competitive niche that had been essentially invented by the first civilian Jeep in 1945, and which was later to be overtaken by straddle-ridden, motorcycle-based all-terrain vehicles (introduced in 1970) and newer, small and sporty (but usually four-wheel-drive), off-road automobiles. The commercial Meyers Manx received widespread recognition when it defeated motorcycles, trucks and other cars to win the inaugural 1967 Mexican 1000 race (the predecessor of the Baja 1000). It crossed automotive press genre lines, being selected as the cover story in the August 1966 issue of Hot Rod magazine. Approximately 6,000 of the original Meyers Manx dune buggies were produced, but when the design became popular many copies (estimated at a quarter of a million worldwide) were made by other companies. Although already patented, Meyers & Co. lost in court to the copiers, the judge rescinding his patent as unpatentable, opening the floodgates to the industry Meyers started. Since then, numerous vehicles of the general "dune buggy" or "beach buggy" body type, some VW-based, others not, have been and continue to be produced. An early example was the Imp by EMPI (1968–1970), which borrowed stylistic elements from the Chevrolet Corvette but was otherwise Manx-like. A later 1970s Manx clone was the Dune Runner from Dune Buggy Enterprises in Westminster, California. The Meyers company attempted to stay ahead of this seemingly unfair competition
