Hummer family
When it comes to Hummer (HUMMER), you will immediately think of that vehicle with the title of off-road king, especially during and after last year’s Iraq War. You can always see American soldiers patrolling the streets of Baghdad in Humvee military vehicles on TV, or at the scene after being attacked. But what you see on TV is a military Hummer, which you cannot buy. No matter how high the price you pay, you can only buy the civilian version of the Hummer. The civilian version of the Hummer whose performance and appearance are closest to the military Hummer is the H1, which is a true off-road vehicle. Its basic price in the United States is US$105,000. If you can't afford this price, you can buy the Hummer H2, which is a popular SUV in China. Its basic price is US$48,800 (it was once listed at 1.5 million RMB in the Asian Games Village market, and is now priced at 1.18 million RMB) RMB). Starting this summer, the Hummer H2 SUT will also go on sale, and its price is still a secret. What is SUT? That's what "sport utility truck" means. In the United States, truck generally refers to a pickup truck that we Chinese people don’t take seriously. Driving a pickup truck in the United States is like wearing jeans. Anyone can drive it, regardless of whether they are rich or poor. And to a certain extent, driving a pickup truck is more "American" than driving a car or SUV. However, Hummer's high price has turned away many Hummer fans. Its wide body also seems too overbearing, and its "gas tiger" large-displacement engine is also unaffordable for many people.
H3T——Hummer's younger brother
Wherever there is a need, there are products. The small Hummer H3T concept car designed for young people was recently unveiled, suddenly arousing the hopes of many Hummer fans. The H3T is a single-row pickup truck. Although it is the smallest Hummer, with a length, width and height of only 4443×1893×1795mm, it inherits the rebellious styling characteristics of the Hummer H1 and also has the DNA of an American military vehicle. The H3T's two-door, two-seater pickup truck design is the most fashionable body shape in the United States today.
The Hummer H3T looks like a pickup truck, which is different from its three older brothers H1, H2 and H2 SUT. Its top can be opened electrically and the rear window can be hidden to create a completely open cabin. The H3T's hood still opens forward like its older brothers, but semi-automatically. It is extremely passable, equipped with 34-inch tires, and has a ground clearance of up to 11.5 inches, allowing its approach and departure angles to reach 51 degrees and 50 degrees respectively. Although you can tell at a glance that H3T is a member of the Hummer family, due to its smaller body size and slightly smoother lines, it looks more approachable than its older brothers. At least it is not as brutal as H1, nor as ostentatious as H2. . At the same time, the compact body size also makes H3T appear more dynamic and responsive.
H3T's tire and interior design are the product of cooperation with Nike, the world's leading sportswear brand. Nike applies its production technology in sports shoes to H3T tires, making them have strong grip no matter what kind of road surface it is on; Nike's production technology in sportswear is applied to H3T's seat fabrics. This kind of fabric is not only lightweight, but also does not require mechanical means to achieve a warm and spring-like or refreshing and pleasant effect.
In the past, Hummers were developed on GM's full-size truck platform, while the H3T is designed on GM's medium-sized truck platform. Its four wheels are close to the four corners of the body and use four-wheel disc brakes. There are 6-piston calipers on the front disc and 4-piston calipers on the rear disc.
H3T is equipped with GM's new Vortec 3.5-liter inline five-cylinder engine, with a maximum power of 350 horsepower and a power of 100 horsepower per liter. The maximum torque is 474Nm.

H1 - Hummer boss
For 4×4 fans “The King of Off-Road in the World” is not an exaggeration at all to describe Hummer H1. It is the closest Hummer model to an American military vehicle.
Where to start introducing the off-road performance of H1? Its minimum ground clearance of 406.4mm is almost twice that of any other 4×4 vehicle. Its approach angle and departure angle are as high as 72 degrees and 37.5 degrees respectively, which are unmatched by other off-road vehicles. Its 17-inch wheels wear 37-inch tires, and only large trucks can have such big feet. The maximum climbing angle of H1 is 60% (31°), the maximum side inclination is 40% (22°), and the wading depth is 762mm.
The Hummer H1 is equipped with a four-wheel drive system called TorqTrac 4 technology. It automatically reduces the speed of a spinning tire by applying brakes to the spinning wheel, while the differential automatically redistributes drive power to the four wheels. If these are not enough for you, you can choose an "Off-Road Adventure Package". This set of equipment includes a variety of off-road equipment, such as front and rear Eaton locking differentials. When you drive the H1 to climb rocks, climb large slopes, or cross deep ditches, you can press a button and the front and rear differentials will immediately lock. stop to help you overcome obstacles. The "Off-Road Adventure Package" also includes a 12,000-pound winch, off-road-specific tires, and more.
The Central Tire Inflation System (CTIS) on the H1 allows the driver to adjust the tire pressure when needed. For example, on icy and snowy roads, loose sand or muddy areas, you can press a button in the car to adjust the tire pressure. Deflate some tire air; press this button again to restore the original air pressure.
H1’s comfort, safety and convenience are also unambiguous. The 2004 model comes standard with a six-disc CD, electric heated windshield, tire pressure monitoring (part of CTIS), downhill windows, Electrically heated exterior mirrors and remote keyless entry system, etc.
The 2004 H1 is still equipped with a 6.5-liter V8 supercharged diesel engine, with a maximum power of 205 horsepower (152 kW) /3400rpm, and a maximum torque of 596Nm at 1800rpm, which is really scary. These indicators are respectively 7 kW and 14 Nm higher than the 2003 model.
H1 adopts four-wheel independent suspension with variable ratio heavy-duty coil springs, and the front suspension is also equipped with a stabilizer bar. The braking system is four-wheel disc and four-channel ABS.
H2 - SUV Terminator
The Hummer H2 is inspired by the Hummer H2 concept car at the 2000 Detroit Auto Show. At that time, people called H2 a little Hummer. In fact, H2 is not small at all. It's just that the powerful functions of the Hummer prototype, the H1, make the H2 look small.
H2 inherits the excellent off-road performance of H1 while adding some comfortable features. It's a bold and youthful take on the Hummer. In terms of off-roading, H2 can drive in 50 cm deep river water, cross 40 cm high steps or rocks, or travel in the desert for a long time.
H1 car owners generally include people who have money and leisure. They own an average of more than 6 cars, ranging from standard sedans to Rolls-Royce and pickup trucks. They buy Hummer for its special image and Unparalleled functionality.
H2 is aimed at younger and more mainstream consumers. H2 can be used as a daily vehicle, and can also be used for the most extreme off-road activities. H2 mainly targets the following two groups of people: independent tough guys and successful people.
H2 is attractive to both types of people. First of all, the bold design is enough to attract people’s attention. And the brand recognition is very obvious. Anyone who sees H2 will regard it as a powerful off-road vehicle. H2 looks and feels like it conveys a sense of strength, power and control. These are what the two groups of people mentioned above are pursuing. Specifically, those tough guys prefer to drive H2 off-road to experience the limits of its various functions. Those who are successful are more willing to drive H2 on the road to show their boldness and success. So according to these two tendencies, H2 provides two completely different configurations.
The H2’s standard power configuration is General Motors’ VORTEC 6.0-liter V8 engine. The transmission is a weighted 4L65-E four-speed automatic transmission. The engine has a maximum power of 325 horsepower and a maximum torque of 385 pound-feet. The four-wheel drive high-speed mode of the transmission is also the towing mode of the H2. The four-wheel drive mode is an integrated two-speed electronically controlled full-time four-wheel drive system. When necessary, this system can achieve a reduction ratio of 2.64:1. Using this reduction ratio, you can effectively climb over larger obstacles. By controlling the reduction ratio, the H2's transmission has a towing capacity of 6,500 pounds in first gear. The H2's front-to-rear torque distribution is 40/60. When the front and rear differentials are locked, torque distribution is 50/50 front to rear. The electronic control system of the transmission can provide 5 mode selections, including rear axle differential locking, which is the most commonly used mode for off-road vehicles on harsh terrain.
H2 inherits the mantle of Hummer, with short front and rear overhangs, providing H2 with almost maximized approach and departure angles. Both of these angles are the largest on the H2 among GM trucks. The rock guard on the chassis adds to the rugged personality of H2. The fenders include a large, thick fender, fuel tank lower plate and rocker guard fixed to the frame. If air conditioning is optional, compressor guards and fenders can also be installed.

HMMWV - the legs of the US military
In the late 1970s, the US military became increasingly dissatisfied with various military vehicles and decided to develop a multi-purpose high-mobility four-wheel-drive vehicle ( High Mobility Mutlpurposc Wheeled Vehicle-HMMWV, now nicknamed Humvee by the US military), in addition to transporting personnel, it can also set up machine guns, rescue the wounded, launch missiles and other military tasks that old jeeps cannot perform.
At that time, three companies submitted bids to the military and provided HMMWV design blueprints. After ten years of fierce competition, AM General took the lead in sending prototypes to the Nevada Automotive Testing Center, the largest vehicle testing center in the United States, for comprehensive testing. The final model design uses a V8 6.5-liter diesel engine, a four-wheel independent suspension system, a permanent four-wheel drive system, a low body, and a wide body. In 1984, it passed various rigorous tests and became a new generation of multi-purpose off-road vehicle. It was officially named HUMVEE and received a US military procurement contract of 55,000 units.
During the 1990 Gulf War, the HMMWV stole the show, prompting manufacturers to launch the civilian version of the Hummer. To date, more than 140,000 Humvee military vehicles have been produced, and the US military has equipped 100,000 of them, and exported them to more than 30 countries and regions. In addition to U.S. Navy and Air Force equipment, the U.S. Army has about one Humvee for every ten men.
In the 2003 Iraq War, the military Hummer once again made outstanding achievements. However, after the end of the main battle of the US military in Iraq in early May, the situation of the HMMWV tank was somewhat embarrassing. From politicians to the public in the United States, they were criticizing Due to the lack of necessary protective measures on the HMMWV, the lives of many American soldiers could have been saved. These lighter Humvees and other military vehicles have become prime targets of choice for anti-American guerrillas. Everything from roadside bombs, land mines, rockets, and even a simple AK-47 rifle round can penetrate this unarmored vehicle. Most of the American soldiers who died later died in Humvee military vehicles. The high-speed and menacing Humvees have almost zero protective performance, which is also the biggest problem that Humvees will face in the future.
