Designed in Detroit by custom off-road/overland vehicle manufacturer Mil-Spec Automotive and hand-built by a small team of specialists in Wichita, Kansas, the Mil-Spec Hummer H1 Launch Edition is the culmination of a lofty goal: to embody the full potential of “what an AM General Hummer can be.” Taking a common sense approach, Mil-Spec began by addressing the three elements of the existing Hummer that begged for attention: the powertrain, build quality, and interior.

The Launch Edition replaces the Hummer’s standard powertrain with a Duramax 6 turbocharged diesel V8 engine and an Allison 1000 6-speed automatic transmission that incorporates multiple internal design improvements, adaptive driving technology, and protective limp mode integration. The chassis of the Launch Edition features an enhanced build quality with tri-level sound insulation and a Kevlar coating for maximum durability. Mil-Spec also completely redesigned the Hummer’s interior with an emphasis on luxury materials, striking aesthetics, and ergonomic functionality.
