Surprise! GM putting aluminum in next-gen pickups

Last month, General Motors launched a series of ads touting the benefits of steel over aluminum – specifically, with regard to the Chevy Silverado versus the Ford F-150. (Kind of. We're not sure what a grizzly bear has to do with anything.) We took issue with the ads, with editor in chief Mike Austin saying they "reek of insecurity, and distract from the Silverado's strengths that could be used for positive advertising." But what bothers us more, is that yet another report surfaced claiming anti-aluminum GM will indeed use the weight-saving material in its next-generation fullsize trucks. On Tuesday, GM announced a $877-million investment for its truck plant in Flint, MI. But Reuters says that huge overhaul is because the trucks will use "substantially different equipment than the tools GM uses today." The report specifically states, "People familiar with the company's plans say GM's next-generation pickups and SUVs will make use of various materials, including aluminum and lightweight steel, to shed weight and gain fuel efficiency to meet tougher federal standards." The Silverado already uses a few aluminum components in the engine and hood, and if more widespread use will help GM build its best fullsize trucks ever, then that's great. Honestly, we have no reason to doubt that aluminum will be used in the next Silverado and GMC Sierra. We just hope GM remembers that nothing is ever truly deleted from the bowels of the Internet when it launches the subsequent "look how great aluminum is!" campaign.

GMC caught using Rivian R1T image for Sierra Denali EV Photoshop

The rise of electric start-ups have many legacy automakers checking their rear view mirrors as they scramble to join the EV party. Most wouldn't like to admit it publicly, but we know that at least some folks at General Motors are keeping an eye on Rivian. That's because a recent post on social media account by the General Motors design department appears to have used an image of the Rivian R1T, but heavily photoshopped. The post was intended as a peek of the GMC Sierra Denali EV's rear view. Eagle-eyed observers like AllCarNews soon noticed many familiar elements to the rendering, including the wheels and tires, mirrors and doors. Even the backgrounds are identical, including some leaves that the truck is kicking up. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Seen side by side, the two pickups' similarities don't end there. The Sierra EV is wider, but the cab's rear pillars and glass look the same as the Rivian's, just stretched horizontally. The rear bumper and its license plate cutout and reflectors on either side look a bit too close for comfort as well.  The post as since been deleted. A GM spokesperson explained the situation to The Drive, "The GM Design Instagram channel is meant to give followers an inside look at the process of designing new products and the creative teams behind it. Often, these posts use sketches made for internal studio use during design development. The sketch in question was intended for internal use only, and was posted without the necessary approval. It has been removed from the GM Design Instagram page." Automakers often use products from the competition as benchmarks or design inspiration. Designers sometimes use existing images as a starting point as well, in order to quickly get an idea down "on paper". They just tend to do it in private. A juggernaut like GM using an image from an upstart like Rivian is embarrassing for the General, but surely an ego boost for the EV brand.  When dealing with an up-and-comer, perhaps it's best to take a page from Mad Men's Don Draper. In season four of the advertising drama, a newspaper calls the hot shot exec for a quote, after a young rival publicly says he's gunning for Draper. Draper knows exactly who the reporter is talking about but when asked for comment says, "Never heard of him." Related Video This content is hosted by a third party.

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.
