The Hummer H1 is a civilian vehicle based on the High Mobility Multipurpose Wheeled Vehicle (HMMWV), popularly known as the Humvee, which was created by AM General.
History Originally released in the civilian market in 1992, the Hummer H1 owes its birth to the popularity of photos from Operation Desert Storm and the enthusiastic campaign from actor Arnold Schwarzenegger, who personally owns several variants of Hummer vehicles. GM announced that 2006 would be the last model year for the Hummer H1 with production winding down in June 2006, due to a new emission laws for Diesel engine vehicles which take effect in 2007. No version of the Hummer H1 ever produced would meet these new standards. AM General currently has orders for an excess of 50,000 new HMMWVs to be produced between 2006-2009 for the United States Military. AM General also will continue to produce the H1, just not the Alpha. These vehicles will be sold through Fleet sales. The next H1 will most-likely bear a refined version of the prior 6.5L Turbo Diesel engine, but that has not been confirmed. Selling the H1's through fleet sales will allow the AM General to not be subjected to the new emission rules and regulations. AM General has sufficient fleet orders to produce 600-800 units per year right now.
Specifications The Hummer H1 has three common variants: a convertible-like soft top, a four-door hard top pickup truck and a Wagon body version. Other less known variants include a two-door pickup truck and a four-door slantback. At this time, the convertible/soft top and the station wagon versions are the only ones available in the mass market. The two door and four door pickup versions are only available in fleet livery.
Five engine types and three automatic transmission types can be found in Hummer H1s. The common engine/transmission combinations are: * 6.2 L Detroit Diesel V8/GM TH400/3L80 3-speed * 6.5 L Detroit Diesel V8/GM 4L80-E 4-speed * 5.7 L Vortec 5700 gasoline V8 TBI/GM 4L80-E 4-speed * 6.5 L turbo Detroit Diesel V8/GM 4L80-E 4-speed * 6.6 L Duramax LLY turbo Diesel/Allison 1000 5-speed (model year 2006)
The H2 is the second vehicle sold under the Hummer marque of General Motors. It is a large SUV (though smaller than the Hummer H1) with room for five passengers and substantial off-road ability. The rearmost part of the H2 SUV was modified to a pickup truck bed for the 2004 H2 SUT ("Sport Utility Truck").
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 utility frame, the mid-section is all new and is completely boxed, and the rear section uses a modifed GM 1500-Series frame which is upgraded for the 8000 pound (3629 kg) gross vehicle weight.
H2 sales were initially strong, but fell to 28,898 for 2004 and 23,213 for 2005. The H2 was nominated for the North American Truck of the Year award for 2003.
Engine 2003–2005 6000 6.0 L (366 in³) V8
Capabilities With its high ground clearance, large tires, protective underbody plates, and low gearing, the H2 is capable of climbing over a 20-inch-high (0.4 m) step-up wall. A massive truck frame and wide track 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 specialised vehicle class.
Fuel economy For typical travel on improved roads, users report fuel economy of between 10 and 14 miles per gallon, which converts to between 14 and 17 L/100 km. Worst case urban driving is said to be in the range of 8 to 14 U.S. mpg (21 to 25 L/100 km). Although General Motors does not provide official H2 fuel economy ratings, most reviews have observed high single to low double-digit mileage, similar to the numbers above.
It should be noted that other large vehicles also have poor fuel economy especially with optional larger engines including the Dodge Ram 1500 series pickup trucks equipped with either the 8.3L V10 (MSRP US$48,500) or the 4.7L V8 Flexible Fuel engine running E85 fuel (MSRP US$31,300). Both of these engines are rated at 9 U.S. mpg city and 11 U.S. mpg highway by the E.P.A. as one example.
Criticism The Hummer H2 is one of the most severely criticized civilian vehicles on the market today. Critics have expressed concern at the fuel economy which they cite as being among the most inefficient of vehicles. The Environmental Protection Agency does not test them for fuel economy because of their weight, they are thus categorised as light trucks and thus are not bound to fuel economy standards.
The Hummer H2 is criticised for contributing towards petroleum comsumption in the United States. In addition, they are criticized for obstructing the views of drivers behind them with their large vehicles. Criticism is also leveled at the H2 by safety advocates who have expressed concern that their size and height make them far deadlier to smaller vehicles as well as bicyclists, and pedestrians since the front of the Hummer H2 will likely strike the head and/or chest where injuries are far more life-threatening instead of the knees where regular cars are most likely to impact a pedestrian.
Holden Special Vehicles unveiled a seven litre program at the 2008 Melbourne Motor Show, the last instalment of the company s 20th anniversary celebrations.
The car to be known in its final development stages as the W427 is finished in the same Panorama Silver paint scheme as the original Group A SS VL Commodore, released at the Melbourne Motor Show of 1988, exactly 20 years ago. HSV Managing Director, Scott Grant, said the W427 was a tribute to how far the company has come in just twenty years.
A new six piston front braking system will provide a 50% increase in pad area, while the Holden W427 also receives a revised ESP calibration, six air bags, improved handling and new Magnetic Ride Control settings.
The Holden W427 receives a bimodal active exhaust system to improve noise quality and back pressure management. Styling and design highlights include an all new front fascia, a three piece carbon fibre rear spoiler, 20 inch machined faced alloy wheel, unique exhaust tips and red leather interior. The Holden W427 will go into production in the middle of the year and will be available for sale in dealerships in the third quarter of 2008.
