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.

2019 GMC Sierra AT4 gives Raptor and Ram a new off-road rival

The 2019 GMC Sierra AT4 blends off-road hardware into a modern, thoroughly updated pickup truck that doesn't skimp on power, luxury, or safety equipment. From its higher suspension setup to its available carbon-fiber cargo bed and the new MultiPro tailgate, the 2019 Sierra AT4 is a direct shot across the bow — or cargo beds, if you prefer — of staunch rivals like the Ford F-150, Dodge Ram and Toyota Tundra. Revealed tonight in New York City, ahead of this week's New York International Auto Show, the truck may seem to be in a strange setting. Then again, with the amount of tire-swallowing potholes currently scattered around the Big Apple, a rugged truck like the Sierra AT4 could be the perfect vehicle for either off-road excursions or an especially bumpy commute. Riding two inches higher than the standard 2019 Sierra, the AT4 comes with standard features like all-wheel-drive with a two-speed transfer case, locking rear differential, Rancho monotube shock absorbers designed specifically for off-roading, along with skid plates and 18- or 20-inch alloy wheels fitted with all-terrain tires or optional, mud-loving Goodyear Wrangler Duratecs. Hill descent control and GMC's Traction Select system are also standard. The latter of these two lets the driver choose between preset drive modes, suitable for various types of terrain and weather conditions. The system then adjusts throttle response, shift points, and the electronic stability control according to each mode. Related: 2018 GMC Sierra 1500 buying guide "The 2019 Sierra AT4 is designed for the customer who wants an elevated presence on the road and the capability to venture off life's beaten path," said Duncan Aldred, vice president of Global GMC. "It's also the beginning for the AT4 brand, which will be seen on every vehicle in our lineup in the next two years." Based on the new 2019 Chevrolet Silverado, the GMC Sierra (including the AT4 model) looks to stand out from its corporate cousin in terms luxury touches, along with some subtle exterior details. For the AT4, these visible differences include a body color grill surround and bumpers. Meanwhile, the inner grille, front fog-lights and faux fender vents feature a black-chrome finish. It's not flashy, which is probably exactly what GMC wanted for its upscale truck. The standard engine is a 5.3-liter V8, though buyers can choose an optional 3.0-liter turbo-diesel inline-six or 6.2-liter V8.

Disabled man realizes dream of driving with converted pickup truck

A man with a devastating illness is mobile once again thanks to a heavily modified pick up truck. He hopes he can help others in his situation gain the freedom of mobility they need to lead a normal life. Chris Sauerbaum has a physical disability resulting from chronic inflammatory polyneuropathy, a form of muscular dystrophy where the sufferer's immune system attacks their nerves. Sauerbaum lost both of his legs and is bound to a wheelchair. After 11 years of trying, he finally has a vehicle that he can drive. "You might as well be driving a Lamborghini," Sauerbaum told the York Dispatch as the driver side door extended to a lift to accommodate Sauerbaum's wheelchair. "Everyone comes up and talks to you. You come out looking like a Transformer." It wasn't easy getting transportation that fit his needs. First he bought a Chrysler PT Cruiser, which wasn't large enough to handle the equipment needed to convert the car for a legless driver. In 2013, Sauerbaum and his wife Heather Sloat appealed to local businesses and friends for donations. They raised $10,000 and were able to put a downpayment on a GMC Sierra. The truck then underwent $91,000 worth of upgrades. It was completely outfitted for Sauerbaum, with a large lift to bring his wheel chair up to the driver's seat and joysticks doing the work of peddles and the steering wheel. New York's Office of Vocational Rehabilitation paid for the conversion. "Think of it as a big remote controlled car. An 8,000 pound R/C car," Sauerbaum told the Dispatch. After a week and a half of learning the controls, Sauerbaum was able to drive with confidence again. He will no long need to rely on his wife to get him two and from work, an 80-mile trip each day. Sauerbaum and Sloat hope to start a nonprofit called Drive for Independence that will assist other wheelchair-bound people with the costs of getting a converted vehicle that suits their needs. "It's just one piece of the puzzle to get people to work," Sloat told the Dispatch. Related Video: Weird Car News GMC Driving Ownership Truck Videos disabled ms
