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.

Trademark application points to evolution of new Hummer EV logo

A trademark application has revealed yet another evolution of the logo expected to adorn GMC's new Hummer EV pickup truck, bringing back the big "H" badge utilized on the H2 and H3 model lines of the expanded SUV lineup's heyday.  The image included with the filing depicts a logo that should be familiar to Hummer fans (or really any American who left their house between 2003 and 2010), with "EV" supplanting the old numerical model indicator. The "Hummer" and "EV" typeface appears to be a direct lift from a filing that surfaced back in April.  This should provide some comfort to folks who are fans of the idea of a future-proofed, all-electric pickup, but want something that embodies the charisma and road presence of the models sold in Hummer's now-deceased, not-so-environmentally-spectacular incarnation. While we don't yet know really any details of the new all-electric SUV, we do know it will be sold via GMC dealers, meaning the revived nameplate will not bring the rest of the Hummer brand along with it.  We haven't really seen much of the new truck, save for teasers and hints here and there. Even the "reveal" back in June only gave us a vague, big-picture look at the truck's silhouette, and various companion images and videos have hinted at features such as a removable roof assembly.  The truck’s general shape is off-road oriented with squared-off, sharp lines tracing the entire silhouette. Its big, knobby tires and blocky wheels are clear indicators of what GM was aiming for with this electric pickup. As for the SUV, comparisons to the Ford Bronco four-door will be inevitable. If our eyes are picking up the scale of this photo correctly, though, the Hummer SUV appears to be a slightly larger vehicle than the four-door Bronco is. Although, the wheelbase for the SUV is shorter than that of the Hummer truck. ThatÂ’ll help it off-road. Those small bumpers and short overhangs along with the bumper cutouts should be hugely beneficial to approach and departure angles, as well. GMCÂ’s shots of the Hummer in the studio are equally as revealing. We can see what looks to be an intense front skid plate and two big tow hooks. In addition to the off-road gear, GMC has allowed a look at the frunk. The front “grille” is one piece with the hood of the truck, so the whole assembly pulls up. That makes for what appears to be a very easy-to-load front trunk compared to other EVs that force you to lift items up and over the front of the car.

Supercharged 2015 GMC Yukon Denali sounds evil, runs 0-60 in 4.5 seconds

Speeding along in a sports car is undoubtedly a ton of fun, but some owners need the ability to carry a lot of people and their stuff and don't want to sacrifice the ability to put the power down. The tuners over at Hennessey have that demographic covered with their growling, supercharged power kits for the GMC Yukon Denali. The upgrades come in three forms for the SUV's 6.2-liter V8: HPE550 with 557 horsepower, HPE600 with 605 hp and HPE650 with 665 hp. This video showcases the full-bore version, and this Denali can definitely hustle in a straight line. The power bump comes courtesy of a 2.9-liter supercharger, intercooler and high-flow cylinder heads to add over 200 horsepower compared to stock, and the final result is a bellowing SUV that rears up off he line to throw the driver back into the seat. The sprint to 60 miles per hour lasts just 4.5 seconds. Check out this hasty hauler in action in the video above.
