Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.

2022 GMC Sierra AT4X First Drive Review | Luxury off-roader

BORREGO SPRINGS, Calif. – What does the 2022 GMC Sierra AT4X have in common with the Aston Martin Vulcan, Mercedes-AMG GT, Camaro ZL1 and Ford GT? The answer: Multimatic DSSV spool-valve dampers. These dampers – or shock absorbers as theyÂ’re also called – are a lot like the adaptive dampers found in many sport and luxury vehicles. In a general sense, they allow drivers to select how soft or firm a ride they want, but the Multimatic dampers are quicker to respond and have additional benefits related to off-roading.  Off-roading is the main reason this new AT4X model has been added to the Sierra lineup this year, along with its elevated levels of luxury. ItÂ’s a big step up from the existing less-capable AT4 trim, which misses out on the DSSV dampers, electronically locking front and rear differentials, and 32-inch Goodyear Wrangler DuraTrac Mud-Terrain tires. The timing of this debut coincides with a significant overhaul for the entire 2022 Sierra lineup, including revised styling, a more muscular 2.7-liter turbo-four engine, and most notably, an interior overhaul that replaces this generationÂ’s dull and outdated dashboard with a fresh, modern and more competitive interpretation bolstered by a large 13.4-inch touchscreen powered by the Android Automotive OS. Upping the luxury further is a new, fully-loaded Denali Ultimate trim that includes the Super Cruise automated driving system, though our time in the revised 2022 Sierra was almost entirely in the AT4X. In addition to the off-road equipment and interior improvements listed above, the Sierra AT4X features the 420-horsepower 6.2-liter V8 as standard equipment, improved underbody skid plates, and a new Terrain drive mode. But thatÂ’s not all, because the AT4X is also differentiated by the X-less AT4 with a cabin thatÂ’s almost as extravagant as that luxurious Denali model, minus the availability of Super Cruise. Ventilated seats with massage functions, premium leather upholstery, wood trim and Bose audio are all standard. Altogether, this big truck could be the perfect way to get to your next glamping adventure. We had the opportunity to check out the AT4XÂ’s capabilities within the Anza-Borrego Desert State Park, a few hours east of San Diego. There, we encountered long stretches of dried riverbeds, narrow chokepoints as well as steep climbs and descents. After dropping pressures in the Goodyear mud-terrain tires to a flaccid 15 psi, we skimmed through the silted riverbeds with ease.

GMC teases Hummer EV's removable roof panels

Today was supposed to be the day that GM took the wraps off its GMC Hummer EV. We were told as much during the Super Bowl commercial, but GM revised it to an undecided future date, citing the coronavirus as the reason. Instead of the big reveal, we have a teaser.  The Hummer EV is going to feature removable roof panels, and now we get a better look at them. There are four roof panels and a front T-bar that come out of the truck. You can see what that looks like in the video at the top of this post. Comparisons to Jeep are obvious as the open-air experience is likely similar to the Gladiator and Wrangler with their hardtop roof panels removed. That zero-limits slogan makes a bit of sense from this respect. With the sheer number of roof panels, we suspect a single person will be able to remove them alone. In addition to the video of the roof, we get a small peek at the massive digital screens the Hummer will be sporting. Check them out at the bottom of the photo below. They appear to be two large slabs, separate from each other. Other details are scarce on the ground. We’re not sure when the Hummer will make its grand entrance at this point, but are still excited to see the 1,000-horsepower truck hit the road. GMC is still advertising the 0-60 mph time of just 3 seconds, too. The latest tidbit of news suggests that further teasers might be coming, so we could be in for a rather drawn out reveal process. Our senior green editor John Snyder got to see the GMC Hummer in person earlier this year at GMÂ’s EV Day and described it like this: “ItÂ’s a big, off-road-ready pickup complete with giant all-terrain rubber and tow hooks. It features removable roof panels for access to the open sky, which appears to be depicted in the teaser above. It features sail panels behind the C-pillars, similar to those on the Chevy Avalanche and Honda Ridgeline. Its bed was concealed with a tonneau cover, but it sported GMCÂ’s MultiPro tailgate that we first saw on the Sierra Denali. Interior photos showed a spacious interior with blocky shapes, squared hourglass vents that mirror the look of the taillights and a lunar theme that incorporates the topography of the Sea of Tranquility into things like the floor mats and speaker covers. It also has a large infotainment screen as well as a digital instrument panel.” Related video:
