| This is the real deal! H1, and Diesel, and Convertible, and a beast! We bought this new in 2002 and have been enjoying it ever since. I must say, for such a huge truck, it is a great driving truck. I primarily use it for off-road use, and no hills, boulders, ruts, mud, or water seem to stop it! Here is a bit of history of the Humvee…The Hummer H1 is a civilian off-road vehicle based on the M998 High Mobility Multipurpose Wheeled Vehicle (HMMWV, or Humvee), which was created by AM General. The vehicle was produced from 1992 through 2006, and was the first of what became the Hummer line. The Hummer H1 shares some common driveline parts with its HMMWV brethren. Items like brakes, axles, frame and major body panels (hood, tailgate and quarter panels) are identical between the HMMWV and the Hummer H1. All Hummer H1s and HMMWVs come off the same assembly line, and then civilian H1’s get painted and finished in a separate building across the parking lot.Hummer H1’s are unique in the way they handle off-road, and in their interior arrangement. Passenger and highway comfort are sacrificed for maximum mobility compared to civilian SUVs, with features much more radical than the original Jeep, though they do share a similarly cut simple grille opening. They are inherently very stable, thanks to their wide stance. They also can ford 30 inches (76 cm) of water, climb a 22-inch (56 cm) step, have a stock ground clearance of 16 inches (41 cm). This high clearance is made possible by tucking driveline components inside a channel in the central space between the left and right seats. They have high approach/departure angles of 72/37.5 degrees. Most H1’s are equipped with a Central Tire Inflation System (CTIS), which enables the driver to increase or decrease the tire air pressure at will- since lower tire pressures are more suited for off-road, and higher tire pressures are desirable on-road.Hummer H1’s have many unusual features. They use inboard brakes. They have portal gears, allowing the drivetrain’s half shafts to be up high for greater clearance. The radiator is up high, sloping back over the engine on a forward hinged hood. The air intake is mounted high, enabling fording waist-level water. Rather than using simple runflat tires, aluminum or rubber inserts are an optional feature for runflat ability. Chemical warfare resistant paint is available only on the military version.
