U.S. Army purchases GMC Hummer EV for Light Recon Vehicle testing

The military has been analyzing alternative powertrains for a while, and working with GM vehicular products in that field for at least seven years. In 2016, we got a look at a rebodied Chevrolet Colorado ZR2 with a hydrogen fuel cell powertrain developed by GM and the US Army Tank Automotive Research Development and Engineering Center. In 2017, the automaker created its GM Defense division, winning two contracts for conventionally powered trucks in 2020 and 2021. The Detroit Free Press reports that alt-energy is heavy in the frame, the Army having opened a bid for an electric Light Reconnaissance Vehicle (eLRV). Ten companies showed up with product for a demo last year, at least two of which were electric. The U.S. military's largest branch already purchased a single Canoo EV for testing, now it's also bought a new GMC Hummer EV. It's possible that the specific capabilities of an EV are responsible for the Army's quest. The branch canceled its previous LRV program in 2016 that intended to replace the Scout HMMWVs, which were purpose-built versions of the ubiquitous old Hummer. Military.com wrote that the parameters for that search were a rig that could "carry six soldiers, with a total payload 2,100 pounds. The vehicle must not exceed 11,669 pounds so it can be carried internally or sling-loaded by a CH-47 Chinook helicopter. The vehicle must be capable of mounting a weapon system, such as a 30mm cannon, which can engage targets accurately at a range of at least 1,000 meters." Last November, CNBC reported GM Defense was working on a Hummer EV-based military vehicle. Hummer being Hummer, it's likely GM began exploring the martial route once it greenlit the return of the brand. Last year, Defense Secretary Kathleen Hicks told CNBC, "Electrifying the non-tactical fleet, that’s a no-brainer," but the search for an eLRV signals an eye on something more intense than shuttling troops. Breaking Defense reported in 2020 that the Army was "working with a non-profit consortium of more than 200 companies and universities developing clean transportation technologies, CALSTART." Task and Purpose said the Army's brief for eLRV missions was, "'enhanced mobility, lethality, protection, mission load capacity, and onboard power' for six soldiers to conduct both mounted and dismounted reconnaissance and surveillance missions for Infantry Brigade Combat Teams." That's not necessarily frontline service, but it's not necessarily a garrison shuttle, either.

2019 GMC Sierra carbon fiber bed: How it's made

FORT WAYNE, Ind. — The redesigned 2019 GMC Sierra has some pretty nifty features, and the one that has had the most attention is the MultiPro flipping and folding tailgate. But the Sierra also features the first-of-its-kind carbon fiber truck bed. It's interesting, of course, for its capabilities, such as being 62 pounds lighter than the all-steel box. It even adds more cargo volume since the material can be assembled and shaped differently from steel. As it turns out, the assembly process is cool, too, which we learned when GMC invited us to see the beds being made. Every GMC carbon fiber bed starts out as perfectly flat sheets of thermoplastic carbon fiber. The sheets consist of a mix of fibers and resins, a bit like the molded carbon fiber parts Lamborghini uses. The sheets are manufactured by Japanese company Teijin, which collaborated with GMC to develop the bed. They're all delivered to Continental Structural Plastics (CSP) in Fort Wayne, Ind., for construction into the actual bed. The company, a subsidiary of Teijin, makes a wide variety of composite and plastic parts for the car industry, including body panels for the C7 Chevy Corvette. The rectangular sheets are cut to shape and stacked up at a giant stamping press. Robots pick up sheets and slide them onto a conveyor that goes into a large oven. The heat softens the parts so they can be stamped. The large primary bed parts such as the base are stamped by CSP's enormous 3,600-ton press, and the smaller ones go through a 1,000-ton press. Each press can do different parts using different stamping dies, and CSP switches between dies to produce different batches of parts. After stamping, the parts roll out mostly ready for assembly, but there are rough edges that are trimmed off by water-jet cutters. These cutting machines also create holes for fasteners and for parts such as tie-down hooks and lights. The stamping process also provides the carbon fiber bed with a unique Easter egg. On the bottom of the base of the bed, there are two words: "Connors Way." This is a tribute to Tim Connors, who was the chief engineer of manufacturing at GM and a strong proponent of the carbon fiber bed. He was tragically killed in a motorcycle crash a few years ago. The words were added to honor him, and they were fortunately approved for production. There are some components to the bed that aren't stamped from the flat sheets of material.
