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.

GM phasing out light-duty 1500-series vans

In the market for a fullsize van but don't need a heavy-duty model? You're in the minority, and you're also out of luck. That's because there are barely any more fullsize vans on the market with gross vehicle weight rating of less than 8,500 pounds, the threshold that separates light- and heavy-duty vans.
According to PickupTrucks.com, neither the Ford E-Series, Ram ProMaster, nor Mercedes-Benz Sprinter are available in light-duty versions. Few of the Ford Transit configurations are, either, and now General Motors is discontinuing production of the 1500-series Chevy Express and GMC Savana.
Apparently light-duty versions accounted for just 23 percent of Express sales and only 7 percent of Savanas. Add to that the fact that these 1500 versions were the only ones using the old generation of engines and suspension, and that the Wentzville plant near St. Louis, Missouri, is trying to make room for the next Chevy Colorado and GMC Canyon pickups, and the fate of the light-duty GM van was sealed.

2016 Chevy Colorado Duramax gets 31 mpg highway

The 2016 Chevrolet Colorado Duramax and its similarly diesel-powered GMC Canyon sibling are the most fuel-efficient new trucks on the market in America. The Environmental Protection Agency estimates 31 miles per gallon highway, 22 mpg city, and 25 mpg combined for two-wheel-drive Colorado and Canyon diesels. That's just good enough to take the pickup fuel-economy title from the Ram 1500 EcoDiesel HFE, which carries EPA estimates of 29 mpg highway, 21 mpg city, and 24 mpg combined. Four-wheel-drive models offer slightly lower economy figures of 29/20/23, respectively. Drivers can cover quite some distance, too – the GM twins' 21-gallon tanks mean a maximum range of 651 miles. <p>Your browser does not support iframes.</p> Diesel's reputation may be somewhat tarnished in the US after Volkswagen's emissions scandal, but Chevy wants to assure potential customers that there are no tricks with the Colorado's figures. The pickup's engine features NOx-reducing tech like exhaust gas recirculation, and the EPA and California Air Resources Board recently chose the truck to take the additional step of real-world emissions tests. The 2.8-liter Duramax four-cylinder with 181 horsepower and 369 pound-feet of torque had no problems with the more stringent evaluation, and "the agency expressed no issues or concerns," according to the company's statement. The diesel Colorado goes on sale this fall, and the Duramax costs $3,730 over a similarly equipped V6 model. We've gone ahead and included dueling press releases from both Chevy and GMC below for your reading pleasure.

The EPA-estimated highway fuel economy for 2016 Colorado four-wheel drive diesel is 29 mpg. The EPA has issued a Certificate of Conformity for the Chevrolet Colorado Duramax diesel.
