A.P.E.X.

The 12-wheeled vehicle used in the film was created by Jefferies Automotive in Universal City, California. Only one was built at a cost of $300,000 in 1976. The Landmaster is powered by a 391 cubic-inch Ford industrial engine, and features a fully-functional, custom-built "tristar" wheel arrangement, which could actually help it "crawl" over boulders. It also used an innovative steering mechanism that guided the vehicle, not by the front wheels, but by "bending" the middle section with hydraulic rams to effect a turn. The Landmaster's bodywork was made with 3/8-inch steel plating, which helped it tip the scales at over 10 tons. It was so tough, in fact, that it survived a 25-foot jump during testing with no damage. As of today, the original "Landmaster" is alive and well, and is currently in the hands of a private collector who purchased it in 2005. It has been restored to its original condition as seen in the film.

Dr. Sinclair travels to 1973 but a 1975/1976 Jeep is being driven by the hippie family Sinclair encounters.
