Back in the mid-80s, the U.S. Military started using the High Mobility Multipurpose Wheeled Vehicle (HMMWV), which they affectionately called the Humvee. This was a big, heavy military truck capable of running over anything and surviving landmines. Even though they made the Humvee for the military, constant requests for a street-legal version got AM General thinking about entering the lucrative civilian market.
Finally, in 1992, they introduced the civilian Hummer H1. It looked the same as the military version with similar technology and engine. The power came from a 6.2-liter diesel V8 with just 165 HP and loads of torque. Basically, the only real difference between the military and civilian Hummer was the interior.
The street-legal model had a plush interior with air conditioning, leather upholstery, and a premium audio system. The Hummer H1 was expensive, huge and difficult to drive, making it impractical for most drivers. However, it was extremely popular with customers who wanted something different and opulent.
