5 things we love about the 2019 GMC Sierra AT4

NEW YORK — The 2019 GMC Sierra AT4 proves that GM's upmarket truck and SUV brand is getting serious about offering rough-and-tumble capability to rival the Ford F-150, Toyota Tundra, Ram 1500 and Nissan Titan. Until the Sierra AT4 rolled onstage at a media event in lower Manhattan, prior to this year's New York Auto Show, the GMC brand had been more focused on luxury touches like fancy chrome wheels and posh interiors — no surprise, considering the upscale SLT and Denali trim levels account for the vast majority of GMC sales. So now GMC wants to get muddy and adventurous? Well, yes and no. The AT4 adds hardware that'll take truck buyers off the beaten path, though this GMC isn't anywhere close to being a Spartan, no-frills work truck. To better explain, let's look at five key features we love about the 2019 GMC Sierra AT4: More than stickers and chrome The Sierra AT4 isn't a cynical marketing ploy, there is some true all-terrain toughness built into this pickup truck. A factory-installed lift kit raises the AT4 by two inches, while Rancho monotube shocks, a locking rear differential, a two-speed transfer case and standard all-wheel drive prove this GMC can dare to venture off paved surfaces — though you might risk getting mud and muck on the truck's handsome 18- or 20-inch alloy wheels. Power and economy The Sierra AT4 comes standard with a 5.3-liter V8 coupled to an eight-speed automatic transmission. In the standard Sierra 1500, this engine produces 355 horsepower. GMC didn't mention engine specs here in New York, though it's possible the AT4 might get a small power bump. This engine should be plenty for most truck buyers, though GMC offers two tempting alternatives. These include a turbo-diesel 3.0-liter inline-six, along with a 6.2-liter V8. Both motors are paired to stop-start fuel-saving systems, along with a new 10-speed automatic transmission. Carbon fiber cool factor The GMC Sierra's available carbon-fiber cargo bed, called CarbonPro in GMC-speak, trims 62 pounds of weight, as compared to a traditional all-steel bed. This slick feature uses carbon composites for interior panels and, judging from GMC's videos of burly bricks and huge hammers being thrown into a CarbonPro cargo bed, it should prove more than up to the task of ... well, having someone throw bricks and hammers into the cargo area.

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.

2022 GMC Hummer EV Drivers' Notes: We can't stop talking about Crab Walk

The 2022 GMC Hummer EV Pickup defies reason and sense in most ways. It’s a pickup that weighs over 9,000 pounds, but will do the 0-60 mph sprint in around 3.0 seconds. That sounds like something to be afraid of, but itÂ’s also something you want to experience. ItÂ’s a feat of engineering to make something so heavy move so quickly, but thatÂ’s what the EV revolution has brought upon us. GMC gets the Hummer up and moving as quickly as it does with three electric motors — one in front and two in the rear — that combine for a nutty 1,000 horsepower and 1,200 pound-feet of torque. All of that power is unleashed in Watts To Freedom (WTF) mode. Your seat starts rumbling; the air suspension lowers you to the ground, and an electrifying soundtrack is played over the speakers to match your throttle applications. Launching this supertruck is an event every single time, but due to its extra-high ride height and off-road chops, sending it down your favorite trail is, too. That is, assuming said trail is wide enough to fit the gargantuan Hummer. Those knobby all-terrain tires keep the Hummer from being even mildly entertaining when you explore the truckÂ’s handling Â… but who cares. Our specific tester is an Edition 1 model, which means it comes fully loaded with every option you can imagine. As such, its price is $110,295. For the amount of performance and capability on display here, that number sounds surprisingly right. ItÂ’s also befitting the HummerÂ’s status as a supertruck, wherein you get everything youÂ’d ever want in one go-anywhere do-anything package. Editor-in-Chief Greg Migliore — The Hummer EV is the biggest rock star vehicle IÂ’ve tested in quite some time. Literally. ItÂ’s huge and attracts a ton of deserved attention. The Hummer design is spot-on, especially the grille, lights and flared fenders. It looks the part. For $110,000, it should also have some substance, and this Edition 1 delivers Super Cruise, Watts to Freedom and CrabWalk, not to mention GMCÂ’s MultiPro tailgate and the removable Sky Panel roof. It feels quick, as you would expect something with 1,000 hp to feel, and itÂ’s shockingly maneuverable. I CrabWalked down my street to show off, navigating around things on the diagonal and amusing the neighbors. Just the regular four-wheel-steering function, which functions similar to those offered by various other cars, allows the Hummer to turn easily and confidently.
