The Lamborghini LM001 was a prototype offroad vehicle designed and built by Lamborghini. It was first revealed at the 1981 Geneva Auto Show with the new Jalpa.
Despite the failure of the Cheetah project, the idea of a Lamborghini off-road vehicle was still very much alive, and with new capital from investors, the Cheetah concept was redesigned into the LM001. Unlike the Cheetah's Chrysler engine, the LM001 prototype had a 180 hp 5.9L AMC-built V8, with the intention of offering the V12 from the Countach for production models.
The LM001 was found to have unfavorable handling characteristics when accelerating. This problem was traced to the placement of the engine in the rear. As a result, the LM001 was discontinued after one prototype was made.
The Lamborghini LM002 was the follow-up vehicle to the LM001.
