Mil-Spec Makes The Hummer H1 Even More Hardcore

We’d struggle to name an off-roader more hardcore or more militaristic than the Hummer H1. And you can still get one – or a HMMWV, at any rate: in military spec, as a kit to build yourself. But this company is taking it even further.

Based in Detroit and manufacturing in Wichita, Kansas, Mil-Spec Auto has sought to upgrade the original Humvee in every way imaginable. And naturally, that starts under the hood.

Mil-Spec’s Launch Edition packs a 6.6-liter Duramax turbodiesel V8 tuned to deliver 500 horsepower and 1,000 lb-ft of torque. Channeled (of course) to all four wheels through an Allison six-speed automatic transmission, an array of differentials, and a transfer gear case, it’ll run to 60 in 6.8 seconds and top out at 105 miles per hour.

That’s a fair bit quicker than GM or AM General ever offered from the factory. And Mil-Spec offers Stage 2 and Stage 3 tuning options to make it even more potent.

The chassis is also completely re-manufactured and powder-coated, with better sound insulation and matte Kevlar-coated bodywork. The interior is retrimmed in aluminum, leather, duck canvas, and waterproof vinyl, with four individual custom seats, metal fixtures, and a Momo Prototipo steering wheel.

It’s even fitted a JL audio system with a marine-grade amplifier and Bluetooth connectivity, LED interior lighting, USB charging ports, backup camera, and power everything.

Like what you see? The Launch Edition carries a sticker price of $218,499. And Mil-Spec will make you one in a variety of body-styles, including convertibles like the one you see here, as well as two- and four-door, hardtops, slant-backs, wagons, and pickups.

    I like what I see. Only thing I would change is the wheel size for something slightly smaller and the steering wheel.

  • The interior looks so lazy, are you sure this is from H1? What kind of idiot throw that interior and installed that.. I’m now suspect that this is from surplus HMMWV instead.
