GMC introduces off-road performance package for Sierra AT4

GMC is giving its off-road-focused Sierra AT4 pickup even more performance with some factory-installed upgrades. The package is called the AT4 Off-Road Performance Package. With it you'll get the 6.2-liter V8 engine upgrade, cat-back performance exhaust system, performance air intake and 18-inch aluminum wheels shod in Goodyear Wrangler DuraTrac tires. The upgraded performance comes in the form of extra power. Thanks to the bolt-ons, you gain 15 horsepower and 9 pound-feet of torque over the 6.2-liter in stock form. This increases output to 435 horsepower and 469 pound-feet of torque — not too shabby. This package is priced at $4,940, and available for order now. That's a hefty price for what amounts to some minimal bolt-on modifications you could easily do yourself. However, buying it through GM means you get to keep your warranty in place. The Sierra AT4 already has more off-road features than a normal Sierra 1500. You're getting a two-inch lift, four-wheel drive with two-speed transfer case, locking rear differentials, skid plates, Rancho off-road shocks and hill descent control. Both the wheels and tires are available as options already, but this package just bunches related stuff together. It'll be up to you to decide if an exhaust and intake are worth the extra dough.

2023 GMC Hummer paint choices are out of this world

The 2022 GMC Hummer EV Edition 1 came in one color: Interstellar White. Despite production issues potentially pushing Edition 1 builds into the 2023 model year, the Edition 1 will stick to being bathed in that single brilliant shade. GM Authority says it got access to the color palette on the way for the standard series Hummer EVs due next year that shows seven new galactic-themed choices on the way. Interstellar White carries on, joined by Void Black as the only no-cost colors. The others are: Afterburner Tintcoat, said to be an orange hue; Deep Aurora Metallic, said to be some kind of bronze; Meteorite Metallic, said to be a gray; Moonshot Green Matte, which we've seen on early shots of the Hummer EV SUV; Supernova Metallic, said to be dark blue; Tide Metallic, said to be a different shade of blue. GMA didn't get intel on pricing for the cost-extra colors; right now, the most expensive palette option for GMCs is White Frost Tintcoat for $1,095. However, the outlet believes Moonshot Green Metallic will be "extremely limited" and charge a super premium price. If that ends up being the case, it suggests GM has a thing about getting big green for special greens. Cadillac made Dark Emerald Frost a late option on the 2022 CT4-V and CT5-V Blackwings and charged $3,925 for the matte paint job. The brand ended production of Dark Emerald Frost in January, making the color doubly exclusive since it was offered for less than a year at the same time as customer demand far exceeded the number of Blackwings available. Anyone wanting Moonshot on their Hummer should get in line early.  The 2023 GMC Hummer EV will begin production later this year. Last month, GM raised prices for the coming model year by $6,250, and raised the destination fee to $1,995. For the moment, that makes the Hummer EV 2 start at $86,245, the EV 2X at $96,245, and the EV 3X at $106,245. Related video: This content is hosted by a third party.

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.
