Mil-Spec 003 First Drive Review | The ultimate Hummer H1

We're in something of a golden age for automotive restomodding, and into a heady mix that includes Singer's reimagined 911s, Icon's fancy off-roaders, and lots of updated Land Rovers. The latest company with ambitions to become a top-tier custom car brand is Mil-Spec, which aims to do what the aforementioned companies do, but with the big, brash, blunt Hummer H1. And in particular, the company is aiming to make its Hummers a compelling alternative to a used Hummer H1 Alpha. The Alpha is generally considered to be the best of the breed with the most powerful diesel engine offered, larger brakes, and a nicer interior compared with its predecessors. To find out whether the company's early efforts live up to that ambition, Mil-Spec invited us to drive their third completed vehicle, Mil-Spec 003. It started life as a 1995 Hummer H1, and as with all of Mil-Spec's vehicles, it was completely disassembled, and the body and frame media-blasted down to metal. The frame and related components are then powder-coated with a black gloss finish. The truck's aluminum body, in this case a four-door hardtop pickup variant, but is coated in a resilient bedliner-like material designed for easy care. Bits of Kevlar are mixed in with the material for strength, and it can be tinted different colors and have rougher or finer textures. Underneath the body, one of the five different engines that were available on the H1, usually a diesel V8, is replaced with a 6.6-liter Duramax LBZ turbodiesel V8. This engine was available on heavy duty Chevy and GMC pickup trucks, and a related engine was used in the Hummer H1 Alpha. Whereas the engine in the H1 Alpha made 300 horsepower and 520 pound-feet of torque mated to a 5-speed automatic, the Mil-Spec's LBZ has had turbo upgrades and a different ECU tune allowing it to produce 500 horsepower and 1,000 pound-feet of torque. It's also coupled to an Allison 1000 6-speed automatic transmission. The mechanical upgrades don't stop with the engine and transmission. The inboard brakes are given drilled and vented discs, and an ARB Air Locker locking rear differential fitted. Dual auxiliary transmission coolers also make an appearance and can be switched on as needed. The 003 received 20-inch wheels with 38-inch mud terrain tires, but larger tires can be added if desired.

AM General to offer civilian Humvee kit car

For anyone feeling nostalgic about the passing of the Hummer brand, or the actual wartime vehicle that inspired it, now is your chance to own a version of the original HMMWV, albeit without an engine.
After a 12-year hiatus from the civilian vehicle market, AM General is reportedly set to offer a kit-car of the C-Series Humvee. The kit will conform to U.S. government regulations and has been made possible by a deal with General Motors.
The kit costs $59,000 - and you still need an engine. A likely favorite would be a Duramax Diesel V8 and Allison transmission combination, as was found on the H1 Alpha. AM General estimates that an owner could buy the kit Humvee and outfit a powerplant and transmission for $75,000. Not bad, considering that H1 Alpha has an MSRP of $140,000 in 2005.

Report: Last-ditch sale effort for Hummer post wind-down announcement fading

It's getting tough for even the most ardent supporters of the Hummer brand to continue to keep hope alive. Reports the aficionados at HummerGuy.net: "While many of us were hoping for a last-minute miracle to save the Hummer brand, signs from Detroit are indicating that Hummer production will soon cease indefinitely."
It appears as if General Motors has resigned itself to winding the brand down and letting it die a slow, agonizing death. The automaker says that it's no longer considering offers for the brand and dedicated Hummer staff are reportedly be assigned to serve elsewhere.
Oh, and about that "Save Hummer" summit that's planned for April 11th near Chicago? GM, though it is aware of the rally, has no plans to send representation. That sound that you hear? That's just the tolling of Hummer's death knell. Thanks for the tip, Brian!
