The 2017 GMC Yukon XL Denali: Not just for the fertile set

I have a sis whom I've nicknamed "The Vickster." She is a beautiful Amazon, 6'1 on a good day and is the mom to a singleton. So why would my sis need to own a GMC Yukon XL Denali when she doesn't have a brood? Well to this I say, is there a written rule somewhere that states behemoth SUV's must be solely purchased by, you know, school-run moms? I think not! Even though the 2017 GMC Yukon XL Denali is tanker-sized and can swallow up to nine passengers, it has road presence and supreme luxury to boot which is a real draw for not just the fertile set. The Yukon XL Denali is an in-your-face kind of vehicle, and it was all in mine. The monolith has a presence, there's no denying, and even though it is big from every angle, it is far from odious. The stately looking ride has nicely defined slabs of metal, boxy proportions that make you look as it glides down the highway. Giving the Yukon XL my front-to-back once over, I liked its imposing mesh grille, nicely placed chrome accents and badges, riveting upsized wheels, and attractive high-intensity discharge (HID) headlamps and LED rear tail lamps. Once I settled into the cavernous and swanky realm of leather and mellow accent lighting that makes up the Yukon XL's interior, I then realized why "The Vickster" opted for this vehicle. The SUV's interior design is not overdone, no excessive bling to the point of blindness! Tasteful appointments on the Yukon XL include soft-touch leathers, aluminum trim, wood inlays, La-Z-Boy comfy seating in the first two rows (2nd-row power-release fold-and-tumble bucket seats); and thankfully, the non-gizmos overkill command center has large and ergonomically comfy controls. Space for a leggy crew is more than ample in the first and second rows. The SUV's available power folding, third-row fold-flat seats, however, are not exactly cut out for those who have gone past middle school as the seating is less bolstered and a little too close to the floor. Loved the wide and cushy center console that is not only spacious enough for hanging folders or a laptop but most importantly, it's elbow-friendly! Technology on the Yukon XL did not disappoint—particularly with the available built-in 4G Wi-Fi Hotspot for up to seven devices that kept me connected wherever I roamed.

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 shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.
