Torque time | 2017 GMC Sierra HD First Drive

It's not the truck that counts, it's how you use it. It's the heavy stuff you fit in its bed or the extremely heavy stuff that gets hooked up to the tow hitch. The ATV, the Jet Skis, the trailer with more square footage than a Greenwich Village apartment. Perhaps you need to get Seabiscuit or, uh, Mr. Ed to wherever they need to gallop next. In our case, there's a pair of very serious-looking snowmobiles perched atop the bed of a GMC Sierra. They spread out as wide as the extended tow mirrors, and their back halves are dangling precariously beyond the truck. Sterling Archer would be giddy; I'm a little nervous. But only because canyon roads and wide vehicles with a high center of gravity go together like peas and custard. The added weight is no sweat at all. That's because this is the 2017 GMC Sierra HD Denali, a truck with the sort of enhanced power, torque, suspension, and stopping capability expected of a heavy-duty pickup. And for this year, the power and torque get a serious bump courtesy of a new 6.6-liter Duramax turbodiesel engine reengineered from almost the ground up with 90 percent new parts. It's quieter and more efficient and it emits less, while most importantly producing 445 horsepower and 910 pound-feet of torque. That's up from 397 and 765, respectively. Chevy fans will note that the same engine is also available in the updated 2017 Silverado HD. Now, for those keeping score at home, that horsepower is best-in-class but the torque number still falls short of the new Ford Super Duty and its Power Stroke diesel V8's 925 lb-ft. Aw shucks. For the record, GM's engineers didn't seem too concerned that they weren't able to eke out an extra 16 torques just to say they're No. 1. "We wanted to first meet emissions and then deliver the maximum horsepower and torque we could, and deliver it over the widest usability range possible," said chief engineer Eric Stanczak. And let's be honest here, 910 pound-feet is herculean, and once again, a jump of 145 lb-ft. Or one Subaru Impreza's worth. Or 110 more than the best Ram can do on a 2500, and its Cummins turbodiesel's 800 pound-feet was eye-popping not too long ago. (The Ram 3500 maxes out at 900 lb-ft with the right transmission.) Ah, but here's the rub. That Cummins-equipped Ram 2500 can still tow more weight according to SAE-compliant measurements – 17,510 pounds for a Ram crew cab with a short bed versus 13,000 in the similar Sierra 2500. The Ford F-250 can manage 15,000.

2020 GMC Sierra 2500 HD and 3500 HD spied on public roads

We saw spy shots of the Chevrolet Silverado HD a short time ago, and now it looks like GM has got the 2020 GMC Sierra Heavy Duty trucks running around in public too. The one we're looking at here appears to be a 2500 Denali Crew Cab, distinguished easily by the same Denali grille on the 2019 Sierra 1500. Aesthetic differences between the front fascias on the 1500 and 2500 HD are small, but the 2500 is a bit more muscular in the hood and lower trim treatment. GMC doesn't look like it's hiding a whole lot with this camouflage, since the sheets over the grille and headlights are mostly transparent. The black tarp over what appears to be a hood scoop leads us to believe it will have the same type of hood design as the 2018 HD. Other interesting bits revealed here are around the rear of the pickup. We can see the same interface for the MultiPro six-way tailgate on this truck as the 1500, so at least the Denalis will have the trick tailgate (we'd expect every trim to have it, though). Just like we saw on the Silverado, the Sierra HD gets the stepside feature just ahead of the rear wheels. LED taillights are clearly visible through the thin veiling, and GM's rear steps remain as well. in addition to this 2500 HD, our spy photographers also caught a 3500 HD model. This one isn't a Denali, as the grille shows its hand again. The grille is different than any of GM's designs on the new trucks we've seen thus far, actually. GMC showed us a teaser of what a new Silverado HD grille would look like months ago, but this differs even further than that. It looks rather minimalistic under the sheet for now, with strong horizontal slats. The actual shape and design of the truck is revealed for the most part, since it's just wearing a thin body wrap. Its mirror design appears to be different from last year's, as the arm is completely solid. A sidestep right in front of the rear wheels carries over from the 2500 HD too. We imagine both this truck and the Silverado HD will debut early next year during auto show season. Related video: This content is hosted by a third party.

Overland Expo's GMC Sierra AT4X is an Aussie-style ultimate overlander

Overland Expo is a caravan of companies producing everything one could need or want for overlanding. So what better what to showcase the kind of hardcore overlander possible by dipping into that parts caravan than to build just such an overlander? That's what the Expo did in creating its second Ultimate Build, based on a 2022 GMC Sierra AT4X. Overland Expo said it chose the Sierra for the 6.2-liter V8 with 420 horsepower and 460 pound-feet of torque because it wanted to "go bigger and more extreme" than its first build last year, which was based on a Toyota 4Runner TRD Off-Road. This Sierra trim was chosen over its AT4 sibling due to the extra dose of rugged, like the Multimatic spool dampers that provide about an inch more suspension travel front and rear, and the front and rear locking differentials. The Denali-like luxury isn't a bad thing to have, either. The only performance mods are a MagnaFlow cat-back exhaust, Firestone Ride-Rite air springs at the bag and 17-inch Icon Dynamics wheels on 33-inch 33 Firestone Destination Mud Terrains replacing the stock 18-inchers on Goodyear Wranglers.   Rig builder Mule Expedition Outfitters tapped more than 21 exhibitors for components, and spent "hundreds of hours" putting them all together seamlessly. The most eye-catching swap comes from the MITS Alloy three-foot canopy and tray that replaces the pickup bed. MITS is an Australian company, hailing from the land that also gives us overlanding powerhouses like ARB and Old Man Emu, and this is a popular outback-style rig. In addition to the storage areas on the sides and underneath, the canopy holds a Dometic refrigerator, Green Goat Outdoors camp kitchen and an eight-gallon water can that feeds a Geyser Systems shower. A solar panel on the roof routes power to a pair of lithium-ion batteries in the canopy as well, their output controlled by a Redarc RedVision Manager30.  There are plenty of Rigid lights for avoiding trouble, and a Forrest Tool Max Tool Kit plus GoTreads for when trouble inevitably appears anyway. The crew cab should hold plenty of gear, but anything else that needs to be stored outside will go in a set of 3D dry bags.
