GMC Sierra Denali CarbonPro bed is finally, almost here

GMC revealed the Sierra 1500 with the optional CarbonPro bed on March 1, 2018. The bed wasn't available at launch, though. You can't buy it now, either, but it will hit dealerships with limited availability after production starts in early June, exclusively for the Denali 1500 and AT4 1500 trims. The carbon floor and sides replace the steel panels in a normal bed, providing "strength, durability, and scratch resistance" and a potential 59-pound weight saving, depending on the truck's configuration. To make sure the bed had a chance, development engineers replicated "extreme use scenarios" like dropping 1,800-pound gravel loads, 450-pound steel drums, and cinder blocks from various heights. They put a 250-pound man on a snowmobile with studded tracks, had him drive into the bed and then go wide-open throttle. We're told the result was "minimal scratching." On top of the extreme weather testing any vehicle goes through, the team also put a generator in the bed and aim the exhaust into a corner to ensure vibration and direct heat wouldn't deform the carbon fiber. Because of the finer shaping area-specific strength possible with carbon fiber, the bed provides one cubic foot of additional payload space by having its sidewalls pushed further out. The CarbonPro bed doesn't need a bedliner, and is grained at the top for better traction but smooth on the bottom for easier hosing down and dirt removal. Tie-downs at the front of the bed work with molded indentations to hold motorcycle tires, and slots in the sidewalls hold two-by-sixes. The truck maker says the carbon-lined payload area confers "best-in-class dent, scratch and corrosion resistance," but we suppose the nation's pickup truck army will prove that or not. The trucks likely won't have the hardest life at the start, since the Sierra Denali costs $56,790 before even a basic option like four-wheel drive. The real test probably won't come until around 2029, when third owners begin treating their aerospace-inspired thoroughbreds like dray horses.

2024 GMC Canyon AT4X AEV Edition pushes the limits even higher

The GMC Canyon AT4X is already a formidable off-road pickup truck, but now it’s getting even more capable with the addition of the 2024 GMC Canyon AT4X AEV Edition. If youÂ’re familiar with the Chevrolet Colorado ZR2 Bison, then by proxy youÂ’re familiar with GMCÂ’s version of it already. Like the bow-tie version of the pickup, the AT4X AEV Edition is lifted an additional 1.5 inches beyond the regular AT4X, giving it 12.2 inches of ground clearance, which is identical to the ZR2 Bison. You also get to work with a 38.2-degree approach, 26.0-degree departure, and 26.9-degree breakover angle. ItÂ’s fitted with AEV beadlock wheels wrapping 35-inch Goodyear Wrangler Territory mud-terrrain tires and uses hot-stamped boron steel skid plates for the radiator, steering gear, transmission, transfer case, fuel tank and rear differential. Appearance-wise, the AEV Edition sports a new front fascia with integrated fog lights and larger fender flares that facilitate the bigger tires. It uses AEV stamped-steel front and rear bumpers that include heavy-duty recover points, and the front bumper is compatible with a winch. The rear bumper (below) is particularly clever, as it has easily removable plastic corners that can be replaced with 10 millimeter-thick steel skid plates for a little extra protection on the trail. YouÂ’ll find an AEV in-bed mount for the spare tire, too, as the big 35-inch tire doesnÂ’t fit in the usual under-bed storage spot. GMC wasnÂ’t ready to provide hard numbers for payload or towing, but expect the Canyon AT4XÂ’s specs to go down in a similar manner as the ZR2 Bison that lost 230 pounds of payload capacity and 500 pounds of towing. And yes, the AEV Edition retains the AT4XÂ’s high-output four-cylidner that produces 310 horsepower and 430 pound-feet of torque. You get all the other AT4X goodies, too, including things like the Multimatic spool valve shocks and electronic-locking front and rear differentials. It also gets the sweet off-road launch control system that initially debuted on the Bison that can adjust power in real-time based on the traction available off-road. On the inside, the AEV Edition adds three standard auxiliary switches that you can hook up off-road or overlanding accessories to. The truck is also fitted with AEV-embroidered headrests and AEV all-weather floor liners. Pricing for the AT4X AEV Edition isnÂ’t available quite yet, but GMC says itÂ’s expected to be available for customer orders later this year.

NHTSA investigating nearly 750,000 GM models over non-deploying airbags

Nearly 750,000 vehicles built by Chevrolet, GMC, and Cadillac are the subject of a National Highway Traffic Safety Administration (NHTSA) investigation due to non-deploying driver-side airbags. While the investigation is ongoing, the agency believes the issue is likely due to rust particles that form on the inflator's connection terminal interface. The list of nameplates included in the investigation includes Chevrolet's Silverado, Tahoe, and Suburban, GMC's Sierra, Yukon, and Yukon XL, plus Cadillac's Escalade, Escalade ESV, CT4, CT5, and XT4. All of the potentially affected vehicles are 2020 or 2021 models, according to a bulletin published on the NHTSA's website. Investigators launched the probe in April 2021 after 15 consumers reported airbag-related issues, including nine who said an airbag malfunction light appeared in the instrument cluster. More alarmingly, the NHTSA is aware of six accidents that caused significant damage to the car's front end yet didn't trigger the driver's airbag. It adds that there are no fatalities linked to the issue, but there are six crashes and eight injuries reportedly blamed on it. No evidence suggests this problem is related to the millions of potentially deadly Takata inflators recalled over the past few years. General Motors is aware of the defect. It sent a technical service bulletin (TSB) to its dealers in March 2021 to address the aforementioned warning light. The note explains the issue is due to "rust particles in the connection terminal interface of the driver's airbag inflator." The company hasn't issued a safety recall yet, however. Whether it will partially depends on the NHTSA's findings. It's currently looking into the scope and the severity of the problem, and it wants to understand its implications on driver safety. Investigators will decide whether General Motors needs to recall the 749,312 cars that are part of the probe when they close their investigation. General Motors has already spent a significant amount of money replacing defective airbag-related parts in its cars. In November 2020, it was ordered by the American government to recall nearly 6 million pickup trucks and SUVs equipped with potentially dangerous Takata airbag inflators. It repeatedly argued that testing proved the inflators were safe, and it petitioned the agency four times starting in 2016 to avoid a recall, which cost an estimated $1.2 billion (about a third of its net income in 2020).
