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.

GMC Sierra spied with ZR2-style off-road modifications

A few months ago, the 2022 Chevy Silverado ZR2 was revealed with a bunch of off-road goodies to help it achieve a little more parity with trucks like the Ford F-150 Raptor and Ram 1500 TRX. But GM has another full-size truck, the GMC Sierra, and it would seem silly to us if the company didn't share those parts. Based on these spy photos, it seems GM agrees. Though thoroughly camouflaged, we can tell this truck is a GMC Sierra thanks to the sheetmetal on the doors and the distinct shape of the wheel arches. Under the wrappings, we can see that this Sierra features a very different front bumper to the current king of Sierra off-road models, the AT4X. The bottom edge is much higher for better clearance, particularly on the sides in front of the wheels. This is the same type of change applied to the Silverado ZR2's front end. It does appear to be missing the ZR2's skid plate, though we suspect that's a temporarily missing component on this prototype. One other off-road upgrade this Sierra features is a pair of rock rails to protect the rocker panels on the cab. What we can't see are the shocks installed on this truck. If this is a GMC version of the ZR2, it should have the spool-valve shocks from Multimatic. They're some of our favorite suspension components on any vehicle. Other components it should have are locking front and rear differentials, 33-inch tires and a standard 6.2-liter V8. Since the Silverado ZR2 is already revealed and ready for production, we would expect to see the GMC version soon. A good bet would be for a reveal in time for the 2023 model year. As for a name, it's hard to say, since we've already had AT4 and AT4X. It could be named something completely separate from the AT4 line. Related Video: This content is hosted by a third party.

2019 GMC Sierra Denali and its nifty tailgate roll into dealers

We've got more details about the 2019 GMC Sierra Denali now that it's rolling into dealerships, starting with its floor price of $56,195, including destination fee, for the rear-wheel-drive models. That's a jump of $1,900 over the previous generation of its premium full-size pickup. Four-wheel-drive models start at $60,295. The crew-cab truck has grown in every dimension as well, adding about 4 inches to the wheelbase, nearly 2 inches in length and 1.2 inches in width. There's also nearly 3 inches more rear legroom. Bed options are 5-foot-8 or 6-foot-6. There are three engine options. Two are carryovers from 2018: a 5.3-liter V8 that sends 355 horsepower and 383 pound-feet of torque through an eight-speed automatic transmission, and an available 6.2-liter V8 that makes 420 hp and 460 lb-ft of torque and mated to a 10-speed automatic. Both come with GM's dynamic fuel management cylinder-deactivation technology to optimize power and fuel efficiency. A new 3.0-liter turbodiesel paired with a 10-speed automatic is expected in early 2019. The EPA hasn't yet released official fuel economy ratings, but GM estimates them at 17 miles per gallon in the city and 23 mpg on the highway for the two-wheel-drive versions, and 15/21 in four-wheel drive. The truck gets adaptive ride control which can adjust the dampers every 2 milliseconds based on real-time monitoring of the road and driver inputs for improved ride and handling. A new traction select system adjusts the transmission shift points, throttle mapping and StabiliTrak to tailor performance to different terrain or weather conditions. Inside the crew cab, there's new Forge leather-appointed seats, open-pore wood trim and dark finished aluminum decor, plus an 8-inch-diagonal HD color touchscreen with embedded navigation and Apple CarPlay and Android Auto compatibility. Most of the other new stuff we've covered before, including new C-shaped LED headlights and LED tail and fog lamps, optional 22-inch wheels, full-color head-up display, trailer-hitch assist apps and cameras, and rear-camera mirror. The truck also loses up to 360 pounds from the outgoing model via a scratch- and dent-resistant carbon-fiber bed box that replaces steel, and use of aluminum in the doors, hood and tailgate.
