Five hundred horsepower, 40-inch tires, and several cubic acres of off-road cred? It must be a new Hummer from Mil-Spec.

The off-road focused loons at Mil-Spec Automotive have cranked out yet another over-the-top version of the hairy-chested Hummer H1. This time, they’ve given it a Baja bent, slathering it in desert tan paint and all manner of rock-em-sock-em gear.

It is not a machine in which to tackle tight trails, given the company widened the body by seven inches. Keep in mind factory copies of the H1 are already seven feet wide, making this Mil-Spec creation only 6 inches narrower than a London Routemaster bus. The Hummer’s track is stretched over half a foot as well.

Under a hood that rivals the girth of a king-size Sealy Posturpedic is a 6.6L turbodiesel V8 making 500 horses and 1000 lb-ft of torque mated to an Allison automatic. A few aluminium body panels keep #004’s weight just less than that of a large moon. Still, Mil-Spec claims the thing can scurry to 60mph in about six seconds.

It’ll not have escaped your notice this Hummer is offered in a four-door hardtop configuration. In the visage of companies like Singer who have been crafting modern takes on historic machines, Mil-Spec aims to do the same with the venerable Hummer H1. The company leaves no stone unturned when going through the procedure of building a truck for their catalog or a customer.

Want one? Well, unlike most rigs of this ilk, the Baja Hummer is not a one-off. For the princely sum of $218,499 – before the addition of options of course – one can Mil-Spec a Hummer of their own. To create the machine shown here, $31,979 are required including $5499 to craft the truck’s added width. In the great tradition of Porsche, who often charges their customers for the privilege of getting less stuff, Mil-Spec will dent your bank account for $499 to remove their badges. Other options include the likes of power running boards, Wilwood brakes, and a few suspension tricks.
