The new baby Hummer-Hummer h4

Hummer h4

The new baby hummer is on its way. Many rumours have been spreading around the world about upcoming hummer mainly as the General Motors have not yet announced details of the same. Even the name is not clear. Many call it the Hummer h4 as it is the descendant of the previous hummers: h1, h2, h3. Hummer h4 is proposed to be under construction at the GM Hummer division. It may be released in 2008 or 2009. It should be an SUV for city traffic. although this may change by the time it appears around 2010 – it will give the Hummer brand a vital weapon in the United States against premium-priced compact Sport Utility Vehicles. This is a much smaller model. H4 is only the name that is proposed that the company will put to match with the older versions H1,H2,H3. The vehicle executives call the hummer HX. The vehicle will first be previewed as the Hummer HX concept car. It will be more fuel efficient compared to other hummers. This will be a good advantage as the the other hummers are have this disadvantage that they are not at all fuel efficient. It will have unparalleled off-road capabilities and like other current Hummers it would be recognizable from a distance. The HX was designed by the newest designers David Rojas, Min Young Kang and Robert Jablonski. It uses E85 bioethanol, and opens up to it through two removable roof panels.




It will be something like this

Hummer h1

History

The 1980's gave way for the evolution of the High Mobility Multipurpose Wheeled Vehicle or HMMWV or the HUMVEE. It was such a powerful vehicle that it became a part of the United States Army. It could go through any terrain, whether hilly, desert, or just anywhere. It became a part of many operations of the United States Army in different parts of the world.
The vehicle had good off road capabilities. It had great power and could traverse through any terrain easily. This made it a good Sport Utility Vehicle. The production of the Humvee was with the AM General.
It was in 1992 that the AM general released a civilian version of the Humvee in the market. They called this
The HUMMER. It is said that it was the Hollywood actor Arnold Schwarzenegger who asked AM General to make this civilian version of the Humvee after he happened to drive one of them during his movie Kindergarten Cop in 1990. It could be imagined as a Humvee without armours or weapons.
This Hummer was the first of what became the Hummer line. Many variations of the vehicle came to the market in the following years. Perhaps the General Motors announced that 2006 would be the last model year for the Hummer H1, with its production winding down in June 2006 due to a new emission law for Diesel engine vehicles which takes effect in 2007.

Features

The Hummer h1 is available in three different models: a convertible-like soft top, a four-door hard top pickup truck and a Wagon body version. There are also some other versions like the two-door pickup truck and a four-door slantback, but they are very less known.

Humvee-The Military Hummer

History

The HUMVEE can be called the father of all the hummers. Humvee is actually the pet name of High Mobility Multipurpose Wheeled Vehicle or HMMWV. It was made for the us army AM General which was a subsidiary of the American Motor Corporation in 1979.
In 1970's the us army felt that the army trucks then used were outdated and that they couldn't satisfy the requirements of the us army. It was in 1979 that the Army drafted the final specifications for a High Mobility Multipurpose Wheeled Vehicle. The same year
in the month of July, the AM General began preliminary design work on the project, and less than a year later, the first prototype, the M998, was in testing.
The army then gave contract to AM General for the development and delivery of more prototypes of the vehicle for further testing. This was in 1981 June. After this the company got the contract for the delivery of 55000 humvees by the year 1985. It was in 1989 that the vehicle came to the combat scene for the United States invasion of Panama which was codenamed Operation Just Cause.






Features

The Humvee has got portal axles. This is an off road technology where the axle tube is above the center of the wheel hub. This gives the vehicle a higher ground clearance as both the axle tube and the differential casing of the vehicle are tucked up higher under the vehicle. This allows an axially delivered central tire inflation system.
More than 17 different variants of the vehicle are being used in the US for different applications including carrying missiles, cargo, carrying troops, ambulance, direct air support vehicle and many more. It also has the capability of fording 2.5 feet in water normally. With a deep water fording kit installed, it has the capability of fording through 5 feet of water. Also optional equipments like winches and armors can be fitted. The M1025 and M1043/M1044 armament carriers can be used for mounting and firing purposes using the MK19 grenade launcher,the M2 heavy machine gun, the M240G/B machine gun and M249 SAW.
