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.

GM mulling off-road variants of fullsize SUVs

According to General Motors, owners "just love off-roading with [its fullsize body-on-frame sport utility vehicles]," namely the 2015 Chevrolet Tahoe and Suburban and GMC Yukon. If that's the case, it's a bit odd that sales of the previous generation of these models with the Z71 off-road package didn't sell particularly well.
Perhaps, considering this disconnect between owner's thoughts and desires with actual sales, it's not surprising that General Motors is reportedly "considering" an off-road specific model. That means the package would include styling changes and badges along with suspension modifications and larger wheels with appropriately sized fender flares.
There's no indication if the off-road model would be called Z71 or when it may potentially go on sale, assuming it ever goes on sale at all.

2022 GMC Sierra Denali caught towing in new spy photos

The GMC Sierra 1500 was just redesigned for the 2019 model year, but the hyper-competitive half-ton segment will see an updated Denali offering for 2022 and, as we can see from these spy photos, GMC is already testing prototypes.  There's quite a bit covered up on this particular example, leading us to believe the Sierra Denali's refresh will be on the heavy side. We're not surprised, as GM's usually comfortable position within the full-size segment has been eroded over the past few years, largely due to intrusion into the luxury market on the part of both Ford and Ram.  From these shots, we can tell the Sierra Denali will get at least one new grille (if not several of them), new headlights, new bumpers, new bed sides, new tail lights and perhaps even an updated tailgate, though we expect that will matter more on trucks not equipped with the MultiPro multi-function tailgate option, which tends to take up a lot of stylistic real estate.  As comprehensive as that may sound, it's nothing compared to what GMC has in store for the Denali's upgraded interior. Super Cruise — GM's highway semi-self-driving suite — will headline the updates. This is big news for two reasons. For starters, Super Cruise has thus far been relegated only to Cadillac, so the Denali will likely be among the first outside of that model line to offer it. GM also claims that the version of Super Cruise coming to the Sierra is capable of towing. Yes, hands-free towing. Besides Super Cruise the 2022 Sierra is getting a fully digital instrument cluster as part of what appears to be a fairly comprehensive interior redesign, different from both the current Sierra, standard Yukon and Yukon Denali interiors.  Related Video:
