The Lamborghini Cheetah was an off-road prototype built in 1977 by the Italian carmaker Lamborghini. The Lamborghini Cheetah was Lamborghini's first attempt at an off-road vehicle. It was built on contract from Mobility Technology International (MTI), which in turn was contracted by the US military to design and build a new all-terrain vehicle. The basis of the design came from MTI and was essentially a copy of FMC's XR311 prototype developed for the military in 1970. This resulted in legal action from FMC against MTI and Lamborghini in 1977 when the Cheetah was presented at the Geneva Motor Show. The XR311 and Cheetah could be considered progenitors of the current Humvee.
The Cheetah was built in San Jose, California. After initial construction, the prototype was sent to Sant'Agata so Lamborghini could put on the finishing touches. They decided to go with a large, waterproofed 180 bhp 5.9L Chrysler engine, rear-mounted, with a three-speed automatic transmission. The body was fiberglass, and there was enough room for four fully equipped soldiers and the driver.
The engine mounting in the rear gave the Cheetah inferior handling characteristics, and the engine choice was not powerful enough to be adequate for the heavy vehicle (2,042 kg (4,502 lb)), resulting in overall poor performance.
The US military never tested the only finished prototype, only demonstrated to them by its designer, Rodney Pharis. It was later sold to Teledyne Continental Motors by MTI and still exists today.
In the end, the military contract was awarded to AM General and their similar-looking Humvee.
The failure of the Cheetah project and Lamborghini's financial problems led to the cancellation of a contract from BMW to develop their M1 sports car.
Lamborghini eventually developed the Lamborghini LM002 — a similar design but with a 12-cylinder engine from the Lamborghini Countach mounted in the front.
