2022 GMC Hummer Edition 1 weighs 9,063 pounds

From the beginning, the Hummer line of vehicles has been synonymous with the phrase, "absolute unit." The M998 Humvee turned to civilian use as the Hummer H1 came with a curb weight of 7,560 pounds depending on configuration. The much more urbane Hummer H2 didn't sacrifice much of those gains, putting about 6,615 on the scales. Let us not forget that the behemoth gravitational pull and square-jawed mass were what every Hummer buyer wanted. So, starting with the brand values and customer demand, and adding the fact that electric vehicles are substantially heavier than their ICE counterparts, no one should be surprised that the 2022 GMC Hummer Edition 1 weighs 9,063 pounds. That's just one of the substantial figures GMC included in a self-certification filing submitted to the U.S. Environmental Protection Agency, the document rooted out by Car and Driver. Last year GMC told us the Hummer would weigh 9,046 pounds, which proves again the Freshman 15 (or 16) is unavoidable.  Loaded up with humans and their accessories, the truck's gross vehicle weight rating (GVWR) comes in at 10,550 pounds. It takes a few other big numbers to keep that kind of tonnage on the go. The Ultium battery weighs 2,923 pounds. With a 617-amp-hour capacity at 400 volts, total capacity comes in at 246.8 kWh, specific energy at 158 Wh/kg. Usable capacity is about 85% less, at 212.7 kWh. For the time being, these numbers put every other pack in a production vehicle in the shade. That gargantuan chemical plant in the Hummer's floor powers a 329-mile range the same way a giant fuel tanks feed a truck that gets 8 miles to the gallon. The miles per gallon equivalent figures GMC submitted to the EPA are 51 MPGe city, 43 MPGe highway, 47 MPGe combined. Motor Trend questioned whether GM applied the correction factor used for window sticker numbers; if not, the standard 0.7 correction drops the MPGe specs to 36 city, 30 highway, and 33 combined. However, trucks with a GVWR beyond 8,500 pounds don't need to display fuel economy figures on their window stickers, so don't expect to see any such details on dealer lots. For comparison, the Rivian R1T Launch Edition weighs about 7,000 pounds, and fits a 128.9 kWh battery good for an estimated 314 miles estimated at 70 MPGe.

Mil-Spec M1-R First Drive Review | The ultimate Hummer H1 gets better

In 2018, we got our first introduction to Mil-Spec, a company that sought to do to Hummer H1s what other resto-mod companies like Singer and Icon have done to other classic cars. Its initial run of hopped-up Hummers showed quite a bit of promise with an array of mechanical upgrades, including a particularly potent and entertaining diesel engine, plus major improvements to interior livability and luxury. As good as the initial trucks were, Mil-Spec wanted to do even better. It focused on details such as better materials and ergonomics for what it’s calling the second-generation of restored H1s. And all those upgrades are on display in the M1-R, which takes the second-gen M1 and adds some pretty extreme customer-requested modifications. @autoblog WhatÂ’s that? Oh nothing, just a Mil-Spec M1-R rolling on by ##autoblog ##hummer ##m1r ##custom ##fyp ? original sound - Autoblog As with all Mil-Spec Hummers, the M1-R received a comprehensive restoration, taking the body and frame down to bare metal. It was recoated in a durable bedliner-style material made with bits of Kevlar. This particular one was given a tint to make it look like one of the factory H1 colors, Competition Yellow. Steel off-road bumpers, a front brush guard, rear tubular tire rack, fender flares and door panels finished in plain black add contrast and help give it a more rough-and-tumble look. The simple and rugged 20-inch Black Rhino wheels look right at home on the truck, too, especially wrapped in the 38-inch off-road tries. Most of the improvements in the second-gen M1 are found within the cabin. As before, every upholstered surface is made of leather, in this case with diamond stitching that the customer requested. ItÂ’s all done in-house (fun fact, Mil-Spec is now also doing upholstery for private jets). Virtually every non-upholstered surface is made from machined aluminum. That includes the steering wheel, climate control knobs, air vents, window switches, turn signal stalks, even the custom-made ignition key. They all look and feel superb with hefty weight and crisp edges. The toggle switches are a particular treat and return a light, mechanical click with each press. Some of them are a little tough to reach as a result of the HummerÂ’s strange interior layout, but that would be the case even in a stock Hummer. These aluminum pieces are a massive step up from the plastic rocker switches and air vents used on previous Mil-Spec Hummers.

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.
