Hummer: From Army to General Public
Hummer is a brand that specializes in manufacturing trucks and SUVs. It now though belongs to the famous General Motors; the original Hummer was designed by AM General Corporation, a wholly owned subsidiary American Motors Corporation. Before that, a merchant Henry J. Kaiser bought the Willys-Overland, which is better known as GP or jeep in 1953. Then in 1970 the American Motors Corporation acquired the Kaiser-Jeep Corporation. During late 1970s, the United States Army started to develop a High Mobility Multi-purpose Wheeled Vehicle (HMMWV) which could follow the tracks and ruts of full-size army trucks. In 1992, AM General introduced "Hummer" first to the public. And in December 1999, General Motors purchased AM General's Hummer brand.
At first, Hummer is an army used vehicle, which means it has already applied many advanced technologies in producing its vehicles. As any errors in battlefield in army vehicles could be deadly. That is why Hummer uses the best material and equipment to produce its vehicles, which also causes a high price unaffordable for the general public. The powerful Duramax V8 engine however, struck the balance between the consumers' needs for power but also General Motors' need for profit. This 6.6 L Duramax V8 engine could produce 305 bhp at 3000 revolutions per minute, which performs impressively in carrying the bulk and weight of the giant Hummer and transforms it into a vehicle with excellent off-road capacity. However, possessing excellent off-road capacity not only needs powerful engine but also a just equation-tire pressure. Hummer is equipped with the CITS (Central Tire Inflation System), which allows Hummer drivers to inflate or deflate their front tires or rear tires, or four tires altogether. Generally speaking, on flat roads, higher tire pressure is required and on harsher terrain, that high pressure can cause your Hummer tire pop quickly, which is extremely dangerous while driving from plains to terrain. And the CITS solved this problem. What's more, the 4-speed 4L80E automatic transmission used by Hummer is also known as the best and most durable.
Though Hummer owns only several models, its every model is splendid and inspires other models. The Hummer H1 is a civilian off-road vehicle based on the M998 Humvee. It was produced from 1992 through 2006. The three common variants of Hummer H1 are the convertible-like soft top, a 4-door hard top Sport Utility Truck and an Alpha Wagon body version. Other variants such as a 2-door pickup truck, which is used mostly in army or troop; and a 4-door slantback, which shares the same body style of the Humvee. The Hummer H2 is a Sport Utility Vehicle and Sport Utility Truck being slimmer, shorter, weightier and slower than Hummer H1. It could accommodate with six to seven passengers. Hummer H2 was the only one of the trucks to have letters HUMMER between the grilles. With the tremendous ability to haul, Hummer H2 was nominated for the North American Truck of the Year for 2003. The Hummer H3 and H3T truck were the smallest of the Hummer models produced from 2005 to 2010. It featured a 2-speed, electronically controlled full-time four-wheel drive system, which enables it to possess both great on-road and off-road capacity. Though these models are not in production now, they are still very popular among car enthusiasts around the world.
