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 confirms 2015 Silverado, Sierra to get 8-speed automatic

When viewed alongside the next Ford F-150 and the Ram 1500, there is one thing that seems to be missing from the Chevrolet Silverado and GMC Sierra. Where the F-150 will rely on turbocharging and aluminum architecture and the Ram sports an eight-speed automatic and an air suspension, the General Motors twins lack a big, calling-card feature. They're very good, very refined trucks, but one could argue that they're not terribly innovative.
And while it might not be as flashy a feature as air suspension or a lightweight skin, the Silverado and Sierra will get their own eight-speed automatic for 2015, a transmission that will be paired with the company's Ecotec3 6.2-liter V8. The new cogswapper will also find its way into the GMC Yukon Denali, but for now, there's no indication why the Cadillac Escalade, Suburban, Tahoe and standard Yukon are being left out.
According to GM, the new gearbox is about the same size and weight as the current Hydra-Matic 6L80 six-speed. By the time the new powertrain combination enters production late this year, the EPA will almost certainly have gotten around to certifying the vehicles' fuel efficiency. Until then, feel free to speculate. The current Silverado with the 6.2 and six-speed auto returns 14 miles per gallon in the city and 20 on the highway. How much do you think the eight-speed will improve those figures? Scroll down for the official press blast from General Motors, and then head into Comments.

Autoweek dubs GMC Canyon, VW GTI its 2015 'Best of the Best'

For kids around the globe, tis the season for Santa, reindeer and presents. For the automotive industry, the last quarter of each year is reserved for awards, whether they come from Motor Trend, Car and Driver, Automobile, or yes, Autoblog. The latest to get released comes from our friends at Autoweek. The magazine has echoed other outlets, naming a Volkswagen hatchback and a small pickup from General Motors as its Best of the Best. Unlike Motor Trend, which handed out its golden calipers to the Chevrolet Colorado and Volkswagen Golf range, Autoweek doled out its awards to the Colorado's twin, the GMC Canyon, while singling out the hottest version of the Golf, the GTI. "This is the best hot-hatch on the American market – and it may be the best car you can buy for less than $30K," one AW staffer said in the publication's article on the feature. Other staffers praised the absolute value provided by the GTI and the overall fun factor. The Canyon, meanwhile, was saluted for being "the perfect size," not to mention its excellent build quality, feature-rich cabin and overall practicality. "It's truly a truck in the most honest sense of the word," Autoweek wrote of the Canyon. Scroll down for the full press release on the announcement from Autoweek, which includes comments from both Volkswagen and GMC. And then head over and read AW's full feature on the awards. Autoweek names Best of the Best/Car and Truck for 2015 Volkswagen Golf GTI and GMC Canyon signal a strong year for design, performance and value DETROIT, Dec. 16, 2014 /PRNewswire/ -- Today, Autoweek named the Volkswagen Golf GTI as its Best of the Best/Car for 2015, beating a group of finalists that includes the Alfa Romeo 4C, Ford Mustang and Mercedes-Benz C-class; and the GMC Canyon as its Best of the Best/Truck for 2015, besting the likes of the Chevrolet Colorado, Lincoln MKC and Porsche Macan. Autoweek evaluates every new or significantly updated model throughout the year and begins to identify the standouts. Performance, economy, fit and finish, design, value, significance to the auto industry and personal taste all combine to define the Best of the Best. Four cars and four trucks make the grade, and Autoweek editors put them through rigorous road-handling tests at Michigan International Speedway in Brooklyn, Mich. This is where a vehicle transcends the numbers and shows if design, performance and pure driving passion meld into an Autoweek Best of the Best pick.
