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 Hummer EV will weigh 9,046 pounds

In the 2000s, Hummer's unique breed of off-roaders summoned a dark cloud of disapproval from environmentalists because they were gas-guzzling SUVs with mammoth dimensions. GMC's born-again Hummer EV will escape the gas guzzler label by running solely on electricity, but it will be even bigger and much heavier than its predecessors. Enthusiast site GM-Trucks reported the Hummer EV will tip the scale at 9,046 pounds (4,103 kilos if you're outside of the United States) in its quickest configuration, and a GMC spokesperson told Autoblog that figure is accurate. For context, the H1 Alpha released for 2006 (and often considered the ultimate Hummer) weighed 8,113 pounds, the H2 checked in at 6,614 pounds with the 6.2-liter V8, and the H3 was comparatively light at 4,600 pounds. When it lands, the Hummer EV will be one of the heaviest new cars sold in the United States. Part of its plumpness can be attributed to its colossal dimensions; it measures 216.8 inches long, 86.7 inches wide, and 81.1 inches tall. In comparison, the H1 stretched 185 inches long, 87 inches wide, and about 78 inches tall. The electric powertrain also played a major role in slinging the Hummer's weight into dually pickup territory. Batteries are heavy, and the Hummer EV's Ultium pack reportedly has a capacity of over 200 kilowatt hours. It has three electric motors, too. Note the 9,046-pound figure applies only to the sold-out Launch Edition model, which will offer 1,000 horsepower, the aforementioned 200-kilowatt battery, and the supercar-like ability to hit 60 mph from a stop in three seconds. GMC will launch cheaper, slower, and presumably considerably lighter variants of the truck in the early 2020s. Although SUVs are often heavier than comparable trucks due to the additional sheet metal, the people-hauling Hummer should weigh less than the cargo-carrying variant. As we reported in April 2021, its output will be limited to 830 horsepower because it's 20 inches shorter than the truck, and the bigger battery pack doesn't fit in this footprint.

Autoblog Technology of the Year Award Special | Autoblog Podcast #758

This episode of the Autoblog Podcast features Editor-in-Chief Greg Migliore, Road Test Editor Zac Palmer and Consumer Editor Jeremy Korzeniewski. The trio begin by discussing the 2022 Technology of the Year award. Ford's Onboard Scales and Smart Hitch hauling/towing tech as tested in the F-150 Lightning won this year. Why the Ford won, how testing went down and Ford's competition — including the GMC Hummer EV and Genesis GV60 — are discussed. After diving through the Technology of the Year award testing, the three take on this week's news. A mysterious vehicle based on the Corvette (that isn't a Corvette) is supposedly on its way. Audi is giving us "Performance" versions of the RS 6 Avant and RS 7 Sportback. Plus, we discuss a recent study that provides data for the 10 longest lasting vehicles on the road today. After the news, the crew dive into the cars they've been driving this week. Greg's been behind the wheel of a Nissan Pathfinder, while Jeremy and Zac have been driving some plug-in hybrids, including the Lexus NX 450h+ and Autoblog's long-term BMW 330e xDrive.
