Driving impressions:
This truck rocks! Runs like an H1 should. Very meaty midrange. Vastly improved on highway driveability. Engine not much benefit off-road but Allison transmission is. Lower ratios yield improved engine braking and crawl ratio. Tow / haul mode is great, automatic downshifts.
Available February, 2005. Anticipated production 750 units. That number subject to change.

Alpha - The ultimate extension of HUMMER performance
HUMMER will produce a performance series, called Alpha, which takes the brand's legendary capabilities to their ultimate extension. As with all things HUMMER, it starts with the original H1. Here's a preview:
- The 2006 H1 Alpha, launching in early 2005, will feature GM's award-winning 6.6L Duramax Turbo Diesel, mated to the outstanding Allison 1000 transmission.
- The Duramax will bring more power, improved emissions performance, and an unexpected fuel economy gain to the H1, along with adding to its already-unmatched off-road capabilities.
HUMMER's growth strategy began with the introduction of the H2 in 2002. The H2 SUT, featuring a unique rear cargo bed, debuted in June of 2004 and is in high demand at HUMMER dealers with strong initial sales.

According to this article in The Detroit News from July 28, 2004, "GM partner AM General will stop building the conventional H1 this fall, then build H1 Alphas early next year."
