If you belong to the original Hummer fanbase, then Mil-Spec Automotive will have you salivating with its latest H1. This is the sixth H1 that comes out of the Detroit-based company, which specializes at overhauling the off-roaders with extreme attention to detail.

Mil-Spec’s “#006” is based on a 1996 slant-back H1 and features a tactical-inspired design. The vehicle was completely disassembled and rebuilt with much tighter tolerances; even the factory seam-sealed floorpan was replaced with a fully welded aluminum unit, making the interior a much quieter place and saving some weight, too.


One of the highlights of the build is the adjustable Air-Ride suspension, which increases ground clearance when needed. The most important change, though, is the new powertrain, a 500hp 6.6-liter Duramax diesel paired to a six-speed Allison automatic and upgraded part-time two-speed transfer cases. The brakes comes from Wilwood, featuring 12.25-inch slotted/drilled rotors.

The interior is also completely redone and chassis #006 comes with two-tone black leather with marine-grade canvas accents, a Momo Prototipo steering wheel and its own fitted luggage set.


The overhauled Hummer H1 is finished in Deep Sky Black textured spray-on polyurethane material infused with Kevlar to make it more durable against scratches, with black semi-gloss detailing, heavy-duty bumpers, an aluminum snorkel and a 60-inch LED lightbar mounted above the windshield.

If you wonder what Mil-Spec Automotive is charging for this particular Launch Edition (the first out of 12), the answer is a cool US$ 295,039.
