The Hummer nameplate is undergoing a bit of a crisis right now. While the name unequivocally draws to mind images of massive, unruly machines made to suck fuel and tackle anything, GMC would like to change that. With a Hummer EV just around the corner, fans of the old-school model and its attributes will have to turn their attention to the team at Mil-Spec Automotive, and their ridiculously powerful Hummer H1.
Fans of MC&T are likely familiar with Mil-Spec Automotive, the Michigan-based automaker who transform civilian-model H1 Hummers from 1995-2001 into insane off-roaders. These trucks are dramatically improved from their rather spartan beginnings, especially when you look under the hood. In place of the ghastly underpowered drivetrain that the truck came with, Mil-Spec Hummer H1 buyers will find a 6.6-liter Duramax turbodiesel V8 engine that produces 500 horsepower and 1,000 pound-feet of torque. Considering the first Hummer H1 utility vehicles came with only 215 horsepower, it’s hard to argue against the upgrade.
The team at Mil-Spec don’t just shove a powerful motor under the hood and call it good however. They’ve fitted the truck with a new suspension setup, strengthened portal axles, vented and slotted brake rotors set inboard, and a part time 4WD transfer case. Unlike the old school H1s that are locked in at all times, these Mil-Spec trucks can go to RWD for optimal burnouts. There’s even a Kevlar-infused polyurethane exterior coating to protect the bodywork from any sort of dangers that may present themselves off-roading.
New for this year comes the addition of a 30-gallon extended range aluminum fuel cell for those looking to go overlanding. While a Hummer H1 might not come to mind as a great vehicle for this type of endeavor, a Mil-Spec truck has the power and hardware to back up the Hummer’s original claims. It doesn’t come cheap though, as you can expect one of these trucks to run you somewhere in the range of a quarter million dollars.
