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.

2024 GMC Sierra EV Denali Edition 1 reservations closed

Reservation slots for the 2024 GMC Sierra EV Denali Edition 1 are gone. As is the case with just about every vehicle that can be reserved, regardless of cost, there weren't enough slots to satisfy the initial rush. Carscoops noticed the situation first, getting confirmation from GMC that the only avenue remaining for now is to get on a waitlist. GMC's page for the Sierra EV affirms the same, declaring "Reservations are currently full" for the Denali Edition 1. Doing so meant putting down a $100 refundable deposit, a nominal sum that anyone could back out of, but we know by now that market conditions mean between reservation holders and the waitlist there are plenty who will conclude the transaction. Duncan Aldred, head of GMC and Buick, said so himself, telling Automotive News, "It's pretty amazing. A few years ago, when we were planning Hummer, the amount of vehicles sold over $100,000 in the entire industry was not that many. Now, that has radically changed in the last three years. There's been a rapid increase in vehicle prices and there's been an even quicker rise at the top end. We expect to sell out really quite quickly." The Sierra EV Denali Edition 1 comes loaded with quilted seats, real wood trim, Super Cruise, and two motors making a combined 754 horsepower and 785 pound-feet of torque, and starts at $108,695. We don't have a number to put to the phrase "sell out," though. As GM did with the Cadillac Lyriq and Chevrolet Silverado EV, reps wouldn't divulge production caps. Aldred did admit that the reservation number is below 10,000. Two more Sierra EV trims are coming, but they're not due until 2025. That starts with the base Elevation trim bringing an MSRP around $50,000. Note, that MSRP is the prediction now. Three years is a long way away. When reservations open to the public for the standard Sierra EV Denali expected in 2024 and the following trims, GMC plans to keep a tight lid on the pot. Remember, with the Hummer EV, GMC took so many reservations that current production rates mean the automaker won't clear the list for years. Production rates will climb, certainly. However, GM builds the pickups and its Cruise Origin delivery vehicle at its Factory Zero, and there are already 110,000 Silverado EV reservations alone to get through.

GM readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.
