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.

Next GMC Sierra Denali accidentally leaked on consumer site

Thanks to the quick-to-screen-shot folks at GM Authority, we now have our first look at what is likely the 2014-15 GMC Sierra Denali. GMA reports that the image you see here was temporarily posted on the GMC consumer site, though as you can see now, when you scroll over the "trucks" tab, the image has been removed.
GM Authority states that because the truck in this image wears a blacked-out lower bumper, redesigned grille insert and shiny wheels, this has got to be the upmarket Denali version of the fully redesigned 2014 model year Sierra. The Chevrolet Silverado will be getting a similar treatment, as we've seen in recent spy shots, dubbed the High Country.
Expect the Sierra Denali to ride on large, unique wheels (the one we spied earlier this year was fitted with 21-inch rollers), and feature a huge helping of luxurious interior amenities, as well as premium features like xenon headlamps. An official on-sale date for the Denali has not been released, though it's been reported that the high-grade Sierra, along with its Silverado counterpart, will arrive after the Texas State Fair this summer.

GMC talking to dealers about possible Jeep Wrangler competitors

With respect to the team at GMC, it's pretty much fair to say the manufacturer prospers on a lineup of nothing more than gussied up Chevrolets. The brand's successes aside, GMC can be boiled down thusly – the Sierra is a Silverado, the Terrain an Equinox, the Canyon a Colorado and the Acadia is a Traverse, albeit with sometimes dressier duds. Strictly speaking, it's not that simple – Acadia and Terrain have siblings beyond the Bowtie – but the brand is remarkable for its lack of distinctive models. That could change, though, as The Wall Street Journal is claiming General Motors has broached the idea of a building a GMC-badged competitor to the Jeep Wrangler during a meeting with dealers. WSJ claims the new off-roader would "borrow cues and capability" from the defunct Hummer brand. That, of course, could mean many, many different things. While the original Hummer, the H1, was an exceptionally capable vehicle off-road, the H2 and H3 weren't nearly as single minded. It's unclear if a Hummer-inspired, off-road-ready GMC would lean more towards the former than the latter. According to WSJ's report, the GMC Jeep appears to be in the very, very early planning stages, with one unnamed source saying the idea was "being kicked around real hard." GM is still courting dealers for feedback, while it refused the Journal's request for comment. What are your thoughts? Is a Wrangler competitor long overdue for GM?
