From Lamborghini Wiki
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 Corporation engine, the LM001 prototype had a 180 hp 5.9L American Motors Corporation-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.
