Year-by-Year Differences
Updated August 24, 2010
This list documents some, not all, of the changes made to the Hummer from 1992 through 2006. This list is not comprehensive as an estimated 7000 changes have been made over the years. Note the 2005 model year was skipped and the 2006 is the Duramax Alpha. GM has discontinued the H1 as of June 2006.
A word on paint colors: The list only reflects "production" colors which make up about 90% of the Hummers produced. Some of the other 10% are painted at the factory, but in a specially requested color. These trucks will not be found on the list. For example Bob Anderson drives a '95 wagon (SE161064) which is Fly Yellow. His was the first ever truck to be painted in Fly, but the color did not enter production until '97, hence Fly Yellow is listed in '97, not '95. :
