In 2003, under the Hummer brand, General Motors introduced a new line of Hummers that was heavier and longer than its predecessor—the H2. Boasting an average seating capacity of six passengers, the H2 was used as either a typical passenger or off-road vehicle. Although production already seized a few years ago, the H2 is still, without a doubt, one of the best trucks in the automobile industry.
2003-2007: First model
When the first model of the Hummer H2 was released, it was powered by a gas-powered 6.0-liter V8 engine that could generate as much as 316 horsepower. This engine was also coupled to a four-speed heavy-duty automatic transmission with overdrive which was perfect for extreme off-roading. In terms of exterior features, this vehicle had a frame that was composed of three sections: the rear part which used an upgraded GM 1500-Series frame, the midsection which was new and boxed, and the front which utilized an altered utility frame from the GM 2500-Series.
Although the H2 was heavier and longer compared to the H1, it was still equipped with several luxurious features such as a trip computer and heated seats. With a seating capacity of about five passengers, this full-size luxury SUV was nominated as the North American Truck of the Year. It also sold more than 100,000 units during this period.
In 2005, the H2 SUT was introduced. What was different about this model was that the sport utility truck (SUT) version was equipped with the cargo space of a pickup truck. It also had a midgate which made it possible for two rows of passengers to sit inside the vehicle.
However, for the remaining model years, the H2 did not see many changes. It was still powered by the same engine. What's more, because of its gross vehicle weight rating (GWVR), its MPG was not rated. Nonetheless, the first model of the H2 was still famous for its capacity to climb 16-inch tall steps and move through 20-inch deep bodies of water.
2008-2009: Second model
For the 2008 model year, Hummer decided to upgrade the H2 to meet the demands of car enthusiasts. One significant upgrade was the installation of the 6.2-L V8 engine that could generate 393 horsepower. The other changes made to the upgraded model of the H2 were the use of a full-time dual-range transfer case, drive-by-wire throttle setup, and driver-selectable rear differential locker. Because of these improvements, the H2 had better handling and gear change sensitivity.
In terms of luxury features, the '08 and '09 H2s were known for their refurbished cabins. These cabins had improved seats and redesigned interfaces for the switchgear, electronics, and dash. Aside from these, a third-row-seat storage and second-row captain's chairs were made optional in case car owners want a larger interior space. But still, the specialized grille—which contained the letters HUMMER—was still used on these models.
Unfortunately, despite the various amenities of the H2, sales continued to decline. Therefore, General Motors decided to stop the production of this vehicle line in 2009. One year after, the Hummer brand was officially shut down.
