The H1 Hummer is a civilian vehicle based on the High Mobility Multipurpose Wheeled Vehicle (HMMWV), popularly known as the Humvee, which was created by AM General. The H1 Hummers vehicle were produced from 1992 through 2006, and was the first of what became the Hummer line. It was initially known only as the “Hummer”, however in 1999 in a joint venture between General Motors and AM General, GM began marketing the Hummer H2, which was built on the Chevrolet Tahoe chassis. It was at this point that the original Hummer was given the H1 Hummer designation. For collectors, the most desirable model is the Hummer H1 Alpha, produced in the final model year of 2006. It had the most powerful engine and the best fuel mileage of the H1 hummers vehicles. Overall, the H1 hummers vehicle were a very limited production vehicle. “Originally designed strictly for military use, this absolutely massive four-wheel-drive utility vehicle earned its 15 minutes of fame as a civilian conveyance when it became the ride of choice among Hollywood celebrities and professional athletes. Boasting 16 inches (40 cm) of ground clearance as well as super-aggressive approach and departure angles, the Humvee could clamber over a 22-inch (56 cm) high obstacle, handle a 60 percent grade and wade through up to 30 inches (76 cm) of water.” (This article is licensed under the GNU Free Documentation License.
