2019 GMC Sierra Denali MultiPro tailgate and CarbonPro bed explained

When the 2019 Chevy Silverado debuted at the Detroit Auto Show in January, GM's Mark Reuss promised that the new 2019 GMC Sierra would have some significantly different styling and features than its corporate sibling. Previously, the Sierra has been little more than a Silverado with new front and rear fascias and some extra chrome inside and out. Well, Reuss was right. In addition to new sheetmetal, the Sierra exclusively gets the slick MultiPro tailgate and CarbonPro carbon-fiber bed box The tailgate really is trick. At the debut, GMC had multiple demonstrations, with engineers walking us through all six different configurations. Like all Sierra tailgates, the MultiPro version uses an aluminum skin to reduce weight. It's easy to tell which tailgate is which, as the MultiPro has a distinct cutout in the middle where it can fold down or extend. It can be used to extend the bed, drop to allow easier access, provide a sort of workbench, or be used as a step to help get into the bed. Yes, there's even a handle. Ford who? The step itself can support up to 375 pounds, 75 pounds more than Ford's similar tailgate step. This tailgate really is unique to the Sierra and is standard on SLT and Denali models. That said, the power-operated tailgate from the Silverado won't be coming to the GMC. Chevy gets its own exclusive, too. The Sierra's other big exclusive is the carbon-fiber reinforced plastic bed box. CFRP replaces steel inside the bed though not on the fenders. The bed uses four pieces; one for the bottom, one in the back and two along the sides. This isn't a CFRP. There is no steel hiding underneath these panels. Just take a peek underneath. The bed is a composite that uses 1-inch carbon-fiber threads, not a weave. Sheets of CFRP are molded and quenched — a process where the plastic coagulates and solidifies, locking in the carbon fiber — in just 60 seconds. That allows GMC's supplier to crank out these much more quickly. The finish looks like black fiberglass, though an engineer said that this wasn't the final production version. The final model will have different textures in order to improve grip and keep things from sliding around. GMC is touting the material's dent and corrosion resistance, though it remains to be seen how well it holds up to cracking. A video at the reveal showed people going after it with hammers and cinder blocks, but in-person demonstrations weren't available.

GM 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.

2017 GMC Model Year Preview and Updates

GM's 'professional grade' truck and SUV specialist continues to deliver its utility-with-luxury vibe, optimized in the all-new Acadia, relatively new Canyon and continual updates to its Sierra pickups and Yukon SUVs. GMC ACADIA: An all-new Acadia - pictured above - is aimed at the heart of the midsize segment. In an unusual step, the GMC product team downsized the Acadia, dropping 700 pounds from the earlier platform in the process. The new crossover is available in four trims – SL, SLE, SLT and Denali – and an offroad-oriented All Terrain package is available on both SLE and SLT when equipped with all-wheel drive. For young families, GMC introduces the industry-first Rear Seat Reminder, a prompt which will remind the driver to check the rear seat area before leaving and locking the vehicle. CANYON: The midsize pickup introduces two new variants for 2017. The upmarket Denali adds swag – unique chrome grille, 20-inch aluminum wheels and various interior upgrades – to its swagger, while the All Terrain X provides the adventure traveler with all-terrain tires, off-road suspension, Hill Descent Control and all-weather floor liners. SIERRA: The Sierra's maximum trailer tow rating of 12,500 pounds is the best in the full-size, crew cab segment. New features include Teen Driver, active aero shutters on all models and available tri-mode power steps. Also, GMC adds two new colors to the palette: Dark Slate Metallic and Pepperdust Metallic. SIERRA HD: The big news is the addition of the All Terrain X to GMC's heavy duty lineup. With an offroad-specific footprint provided by its 18-inch aluminum wheels and Goodyear Duratrac tires, ground clearance is enhanced by the Z71 off-road suspension, and an Eaton automatic locking differential keeps you rolling. TERRAIN: While the 2018 Terrain awaits its showroom debut, the 2017 Terrain's new Nightfall edition darkens the Terrain vibe. The one new color for 2017 fails to hit a brighter note; it's Graphite Gray Metallic. YUKON/YUKON XL: Perhaps the ultimate Uber capsule, the big/bigger SUV enters 2017 with a host of refinements, including GM's Teen Driver feature, upgrades to rear seat entertainment, available low speed forward automatic braking, active aero shutters for improved efficiency and one new color: Dark Sapphire Blue Metallic. If you're looking to maximize your visual presence, consider the SLT Premium Edition, which ups the chrome content well beyond the commercial minimums.
