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 GMC Sierra Heavy Duty First Drive Review | King of the haul

JACKSON HOLE, Wyo. — The 2020 GMC Sierra Heavy Duty is a bit of a mixed bag. It excels at the tasks an owner is likely to require from a massive pickup truck, but the interior is a definite letdown. Taken as a whole the truck boasts several class-leading specifications and features that make up for the lackluster look and feel of the cabin. And it's much more successful than the mechanically similar Chevy Silverado HD, which shares the Sierra's weaknesses but few of its subjective strengths. GMCÂ’s Sierra HD may share most of its major bits and pieces with the Silverado, but the strongest reason to pick the GMC over the Chevy is that the SLE and SLT trims of the Sierra HD are legitimately handsome. And the rugged, off-road-themed AT4 package is new for 2020 with a blacked-out look that we think a lot of buyers are going to love. Even the ostentatious, chrome-dipped Denali trim looks classy compared to the in-your-face look of FordÂ’s Super Duty line. The same canÂ’t be said for the Silverado HD, which, depending on trim level, varies from garish to just plain ugly. The six-function MultiPro tailgate is the next major differentiator. ItÂ’s not perfect — and mounting a hitch ball in the receiver renders some of its functionality unusable — but itÂ’s unique and potentially very useful to a subset of truck customers. WeÂ’ve covered MultiPro several times already, but if youÂ’re still not clear on its advantages, watch the video below for a demonstration (that's a light-duty Sierra in the video, but the tailgate works the same).

Another unique selling proposition is the AT4 trim, since Chevrolet doesnÂ’t (yet) offer its Trail Boss package on the Silverado HD. The most obvious competitor to the Heavy Duty AT4 is the Ram Power Wagon, and the GMCÂ’s 3,615 pounds of payload and 18,500 pounds of towing capability handily outdo the RamÂ’s ratings of 1,660 and 10,620. Granted, the trucks arenÂ’t aimed at quite the same buyer — the Power Wagon has legit off-road credibility thanks to upgrades like its electronically disconnected sway bars, 12,000-pound Warn winch, and a forward-facing trail camera. But unlike the GMC Sierra AT4, it isnÂ’t available with a diesel. No matter; those aiming for a rough-and-tumble appearance in a heavy duty now have a couple options.

Next GMC Sierra Denali accidentally leaked on consumer site

Thanks to the quick-to-screen-shot folks at GM Authority, we now have our first look at what is likely the 2014-15 GMC Sierra Denali. GMA reports that the image you see here was temporarily posted on the GMC consumer site, though as you can see now, when you scroll over the "trucks" tab, the image has been removed.
GM Authority states that because the truck in this image wears a blacked-out lower bumper, redesigned grille insert and shiny wheels, this has got to be the upmarket Denali version of the fully redesigned 2014 model year Sierra. The Chevrolet Silverado will be getting a similar treatment, as we've seen in recent spy shots, dubbed the High Country.
Expect the Sierra Denali to ride on large, unique wheels (the one we spied earlier this year was fitted with 21-inch rollers), and feature a huge helping of luxurious interior amenities, as well as premium features like xenon headlamps. An official on-sale date for the Denali has not been released, though it's been reported that the high-grade Sierra, along with its Silverado counterpart, will arrive after the Texas State Fair this summer.
