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 Heavy Duty teased, and you better believe there's a huge grille

Chevrolet has shown us a few photos of its redesigned Silverado Heavy Duty, and today we score our first teaser of the GMC Sierra version of this truck. The most controversial feature of the Silverado HD has to be its massive grille, and the Sierra appears to be no different. Just from this photo of the face, we can already tell it's going to be as bold, some might say gaudy, as the Chevy. We'll have to wait awhile to see it all, though, as GM says the Sierra HD will be making its debut in the second half of 2019. It's no Supra teaser campaign, but this one is already starting out pretty early for a work pickup truck. As far as features and technical details go, mum is the word for now. However, we can assume the Sierra will be nearly identical with the Silverado HD powertrain-wise. We know two engines will be offered on that truck, one being a gasoline V8 and the other a Duramax turbodiesel V8 — the former will be mated to a six-speed automatic, while the latter gets the 10-speed auto. Even though it isn't out yet, the torque figure is already less than the Ram and Ford heavy duty trucks at 910 pound-feet from the diesel. The Ram Heavy Duty just revealed at the Detroit Auto Show scores a whopping 1,000 pound-feet of twist in the torque department. We'll know more about the Sierra HD when the Silverado HD presumably gets revealed with full details at the 2019 Chicago Auto Show at the beginning of February. One thing's for sure: If you want chrome and lots of it, you're gonna get it with the 2020 GMC Sierra HD. 2020 Chevy Silverado HD View 5 Photos Related video: This content is hosted by a third party.

Watch GM's new pickup crash its way to five-star NHTSA ratings

General Motors has just scored a big win with its Chevrolet Silverado and GMC Sierra pickup trucks, acing the National Highway Traffic Safety Administration New Car Assessment Program. The two full-size trucks had already netted a five-star Overall Vehicle Score in their crew-cab variants, but the new testing certifies them as five-star trucks in both regular and double-cab bodystyles, so GM's trucks offer top ratings across the board.
"Our incredibly capable trucks have been engineered to be some of the safest," Gay Kent, GM's general director of Vehicle Safety and Crashworthiness said. "We've designed the vehicle structure, strategically placed high-strength steel and developed the occupant restraint system to achieve high levels of safety performance."
The scores mark the Silverado and Sierra as the first pickups to net five-star scores since NHTSA beefed up their testing regime in 2011, a nice feather in GM's cap as it continues to slug out the pickup truck wars with crosstown rivals Ford and Ram.
