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.

2020 Chevy Trax spied sporting design cues from the new Blazer

We saw spy shots in August for what we thought was either a redesigned Chevrolet Trax or new GMC subcompact crossover. At the time we were leaning Chevy. But after this latest batch of spy shots taken near GM's proving grounds, we're now thinking this one is the Trax replacement and the other one was a GMC. For one, the thin row of LEDs looks remarkably similar to the 2019 Chevy Blazer's LED strip. The additional light slightly below that is similar to the Blazer as well, leading us to believe that the next Trax will have a Blazer-esque front end. At first glance, this vehicle looks slightly larger than today's Trax with a much brawnier shape than the current blob-like design. The rear roof cladding could be hiding the same sloped rear window with spoiler hangover we see on the Blazer. Circling back to the other small GM crossover we caught testing, this one doesn't have those Blazer elements. The curved windshield and sloping roof are like those of the GMC Terrain, as are the horizontal grille bars. By contrast, the above car has a straighter windshield and a roof shaped more like the Blazer. One element that does seem to diverge from the new Blazer are the taillights, but they don't exactly look production-ready anyway. If we're right about this being the next Trax (and we're pretty sure we are) then this looks to be a more distinctive vehicle than what it will replace. The mirrors have left their awkward spot on the doors, and it's shaping up to be a much sportier looking crossover as a whole. This vehicle will most likely end up being a 2020 model year car, and if so, we would expect to see undisguised photos of both it and the assumed GMC version next year.

2017 GMC Acadia coming to Detroit Auto Show

Well, it's about time. If there's one group of vehicles that are in serious need of an update, it's the GM Lambda crossovers. You know, the Chevy Traverse, GMC Acadia, and Buick Enclave. They're super old. Good thing, then, that the brand-new Acadia is coming to the Detroit Auto Show next week, as evidenced by this teaser image found on the company's Facebook page. There's not much to see here, except for an LED taillamp signature on what appears to be a much cleaner rear end. We expect the three-row CUV to feature all of the latest GM tech, including a robust infotainment system with Android Auto and Apple CarPlay. V6 power and optional all-wheel drive makes sense here, too, though we won't rule out some kind of four-cylinder option. When GM launched the Lambda crossovers, the Acadia arrived first in late 2006, alongside the now-discontinued (but still very much present in the current Acadia) Saturn Outlook. The Buick Enclave came next, and the Chevy Traverse arrived after that. It's unclear if GM will stick with this rollout plan, of course, but one thing's for sure: all-new versions of these CUVs cannot come soon enough. Related Video:
