The Hummer H1 is the civilian adaptation of the High Mobility Multipurpose Wheeled Vehicle (HMMWV for short), created by AM General. Produced from 1992 to 2006, the Hummer H1 was the first in what would become the Hummer line. The most sought-after version of the Hummer H1 for collectors is the H1 Alpha, which was unveiled in 2006 and featured the best gas mileage and the most powerful engine of all the previous models.
