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 sweetens military discount for Buick, Chevy and GMC

American servicemen and women interested in a new vehicle from Chevrolet, Buick or GMC now have a bit more incentive to head down to their local dealer, as General Motors has announced plans to improve its military discount program.
The new GM Military Discount Program offers eligible consumers a new Chevy, Buick or GMC at invoice pricing, which in some cases can take very large chunks out of a car's retail price. When factored in with other incentives, most of which are available with the Military Discount, the bargains are thick on the ground for members of the US armed forces.
GM's Retail Sales and Marketing Support general manager, Chuck Thomson, said, "GM has long supported the military and military families, and we hope this simplified and enhanced discount will show our appreciation for their service and help make it easier for them to own one of our great new vehicles." The program is open to all active duty and reserve members in the Army, Navy, Marines, Air Force, National Guard and Coast Guard, as well as veterans that have been out of the service for less than a year. Military retirees and their spouses are also eligible for the discount.

GM tells NHTSA pickup truck electronic glitch is 'inconsequential'

General Motors has been enduring some serious problems with recalls recently, and it is hoping to avoid launching another major safety campaign. 200,921 2014 Chevrolet Silverado and GMC Sierra pickups are under the microscope due to a rare problem with their instruments, an issue GM calls calls "inconsequential to motor vehicle safety." The Detroit-based automaker believes that the glitch is so minor that it has filed a petition with the National Highway Traffic Safety Administration asking the government safety watchdog for permission to pass on recalling the vehicles.
The fault at issue can occasionally cause the instrument cluster to reset when drivers use the steering wheel controls to browse songs from an external media device connected to the truck's USB ports. If a song's title information exceeds 2,000 bytes, according to The Detroit News, then the instrument panel can reset, which in turn causes the gauges, shift position indicator and cruise control telltale to turn off briefly. When rebooting, other instrument panel lights may briefly illuminate without their functions actually being activated. GM claims that if this does happen, the instrument display lights go out for about 1.5 seconds and the bulb check lasts a further five seconds. However, this snafu has no actual affect on the truck's operation. The glitch is present in trucks built between January 29, 2013, and October 28, 2013.
