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.

Hummer EV SUV official range announced: 3X truck tops 350 miles

The first run of GMC Hummer EVs were in one single specification: pickup truck in Edition 1 with all the off-road goodies. The most pertinent of those off-road upgrades to electric range being the 18-inch wheels with mud-terrain tires. And it was rated for 329 miles. But now, there are more Hummer variants. The pickup truck is now available with a 3X trim that comes standard with more efficient all-terrain tires wrapped around 22-inch wheels, and there's the SUV with both trims and both types of tires, not to mention a smaller battery pack. And now we have the official range estimates for them. We'll start with the Hummer EV SUV, since all of the official range ratings are new to us. The tires are the key factor, with the all-terrain equipped Edition 1 and 3X both managing 314 miles of range. Yes, this is less than even the mud-terrain-equipped truck, but that's mainly because the shorter length of the SUV means it has fewer battery cells and capacity. It has about 170 kWh of capacity versus the truck's 200+. Adding the Extreme Off-Road Package and its more aggressive tires drops range to 298 miles. The Four-Wheel-Steer system lets the 2022 GMC HUMMER EV Pickup m View 17 Photos As with the SUVs, the Hummer EV truck gets a solid range boost to 355 miles when it's not equipped with the off-road package. There's another benefit to the regular all-terrains on the Hummer EV truck: towing capacity. At 8,500 pounds, it can tow an extra 1,000 pounds over the models with the off-road package. GMC also notes that another potential benefit to the all-terrain-equipped trucks is a suspension tuned for better on-road handling. And our experience has shown that even Hummer with the off-road package isn't too shabby on pavement. Of course, skipping the off-road package will also save you some money, as will opting for the 3X trims. So unless you're really going off-road seriously, and would make regular use of the extra skid plates, under-truck camera and chunky tires, the standard suspension and tire setup really is the way to go.

2015 GMC Yukon Denali

Automotive enthusiasts often wonder aloud - ourselves included - why General Motors would choose to keep GMC while sending Pontiac (and Saturn, and even Oldsmobile before it) into the great automotive graveyard in the sky. The answer, as is so often the case, is profit. It's much easier for GM to rake in money hand over fist by rejiggering the trucks, crossovers and SUVs that it would already be developing for Chevrolet and making them a bit more luxurious and *ahem* "Professional Grade" with new grilles, badges and unique packaging for GMC.
While it may sound like we're being cynical, we totally approve of GM's fullsize SUV strategy. The least-expensive way to get into the fold is with the Chevrolet Tahoe, which starts at $45,595 with a 5.3-liter V8 engine and a cloth interior. Bumping that same Chevy to LTZ trim and its $59,995 sticker price lands a much nicer leather-clad interior and more techno-bells and whistles than you can shake a stick at. But it still looks like a Tahoe, and it still comes with the smaller 5.3-liter engine. Or, you could do what we'd do: Walk into your GMC dealer and take a look at the Yukon Denali. Here's why.
