Hummer H2



Overview


The H2 is built under contract by AM General at a specially constructed plant in Mishawaka, Indiana, USA. Although it shares GM's GMT820 truck platform with the Chevrolet Tahoe and GMC Yukon, those vehicles differ in many ways and are constructed in three other GM plants. The H2's final frame assembly is made up of 3 sections: The front uses a modified GM 2500-Series (or did until November 8, 2009) utility frame, the mid-section is all new and is completely boxed, and the rear section uses a modified GM 1500-Series frame which is upgraded for the 8,600 pound (3629 kg) gross vehicle weight. The 2008 Hummer H2 does 0-60 in 8.0 seconds.

H2 sales were initially strong, but fell to 28,898 for 2004 and 23,213 for 2005. [1] GM Chairman and CEO Rick Wagoner announced on June 3, 2008, the closing of several truck and SUV plants saying high fuel prices have produced a rapid and permanent change in consumer preferences. Wagoner also said GM is looking at possibly selling its Hummer unit after reviewing the SUV brand that is based on military vehicles. The Hummer H3 mid-size SUV gets about 13 to 14 miles per gallon in city driving in the most recent EPA ratings. The H1 and H2 are even larger vehicles with lower MPG, but these are not required by the EPA to post the MPG. The brand has become the symbol to many members of the public of a gas-guzzling large U.S. vehicle. From: [1]

Application

The H2 has a massive truck frame and has a wider-than-average track firm that may offer stability against overturning compared to some of the more common light truck SUVs, although objective tests have not been performed by the government or other outside parties due to its specialized vehicle class. It is marketed as both a general purpose vehicle and as an off-roadFord Excursion, the H2 is also a very common vehicle for a limousine conversion. vehicle. Because of mass marketing by GM, it is primarily used as a passenger vehicle on typical roads. Along with the

The Hummer H2 is also prominently featured on CBS' CSI:Miami, driven mainly by the chief of the Miami-Dade Police Department crime lab (Lt. Horatio Caine, played by David Caruso), as well as three of his colleagues: Detective Calleigh Duquesne (played by Emily Procter), Eric Delko (played by Adam Rodriguez) and Ryan Wolfe (played by Jonathan Togo).

In the 2007 film Transformers, the Autobot field medic Ratchet transforms into a Search and Rescue-themed Hummer H2 for his vehicle/disguise mode. Production designer Jeff Mann had a car built from scratch: "We looked at some military Hummer ambulances and some Red CrossH1 foundation which eventually evolved into a search and rescue vehicle with a crazy color, kind of chartreuse green.[2] vehicles from the '80s that had an

Fuel economy

General Motors does not provide official H2 fuel economy ratings on the gasoline engine it comes with [3]. Motortrend observed 12 mpg. [4] Car and Driver observed 10 mpg. [5] A reviewer at about.com got 8.6 mpg. [6] Edmunds got 9.2 mpg.[7] Four Wheeler magazine observed 10.8 mpg in their final long term report of an H2 SUT (pickup). Their worst tank was 7.2 mpg and best tank was 15.3 mpg. [8] Consumer Guide observed 10.7 mpg, even with mostly highway driving. [9] Automobile Magazine averaged less than 10 mpg. [10] US News observed 9.5 mpg according to its trip computer. [11] Cars.com observed 11.4 mpg according to its trip computer in mostly highway driving. Most vehicles (between 90% and 98%) get higher MPG when driving on the highway, due to reduced acceleration and braking (which burns more gasoline); hybrid cars are an exception to this rule. Car and Driver notes that the 2008 H2 is more efficient than previous models. [12]
