While the LM002's limited production lasted until 1993, only 328 were built, a variety of specialized versions were produced along the way. The LMA, a military variation produced in 1982, early on in the vehicle's cycle, featured an upgraded suspension with heavy duty chassis and steering system. It also offered top-end radio and satellite equipment. The Saudi armed forces took delivery of a sub machine gun turret equipped model that also sported a trap door in the roof.
The LM004, that appeared two years prior to the 1986 production version (don't let the numbering system confuse you) was purely a concept. The consumer oriented truck potentially offered a 7.0-L V12 with slightly higher performance specifications to the LM002. It unfortunately never made it into production.
1988 marked the year Lamborghini chose to enter the LM into the grueling Paris Dakar rally. The experienced driver, Sandro Munari, was to pilot the modified SUV, stripped of its civilized interior and then accessorized with an enhanced tubular roll-over protection cage, racing seats and 4-point harness, plus an ultra-tech GPS system and safety features such as a foam filled fuel tank.
The engine made up to 600-hp, with a short pipe exhaust blatting out a raucous note. Its independent suspension, that incorporated oscillating arms plus coil springs over telescopic shock absorbers, received an upgrade while surround glass was replaced by lighter and safer plexiglass. While the optimized machine never raced in the Paris Dakar, said to be due to a shortage of funds, it did enter the Rallye of the Pharaohs in 1987 as well as the 1988 off-road rally in Greece, with Sandro Munari at the helm, and reportedly faired well despite its large size and smaller competition.
