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.

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.

NHTSA closes 4-year GM investigation, issues common sense advisory [w/video]

Since January 2011, the National Highway Traffic Safety Administration has been investigating a possible problem with corroding brake lines in General Motors' GMT800-platform models, like the Chevrolet Silverado and Suburban and GMC Sierra, in states with salt on their roads in the winter. However, as opposed to launching a full recall of millions of vehicles, the government is issuing a common-sense safety advisory to all drivers in snowy states to keep their vehicle's undercarriage clean. It even has a video explaining things. "Older-model vehicles, often driven in harsh conditions, are subject to corrosion over long periods of time, and we need owners to be vigilant about ensuring they, their passengers, and others on the roads are safe," said NHTSA Administrator Mark Rosekind in the announcement of the end of the investigation. The agency was clear in its report that "brake line corrosion seen in the GM vehicles was not unique," and the government "has not identified a defect that would initiate a recall order." Instead NHTSA is advising drivers, especially those of vehicles from before 2007, to wash their vehicle's undercarriage in the winter and spring to remove salt or other de-icing chemicals. It also recommends regular checks by a mechanic to make sure everything is in proper order. According to the investigation documents, for just the GMT800 platform models, NHTSA found 3,645 complaints of brake line corrosion, which included allegations of 107 crashes and 40 injuries. The issue was found to be more common in vehicles over 10 years old. GM has released a statement (embedded below) that the company "supports the consumer advisory from NHTSA urging regular maintenance and care of brake lines on older vehicles." NHTSA Closes Investigation into Brake-Line Failures NHTSA 13-15 Thursday, April 9, 2015 Agency issues safety advisory on preventing undercarriage corrosion WASHINGTON – The Department of Transportation's National Highway Traffic Safety Administration (NHTSA) today issued a Safety Advisory and consumer video encouraging owners of model year 2007 and older trucks, SUVs and passenger cars to inspect brake lines and thoroughly wash the underside of their vehicles to remove corrosive salt after the long winter in order to prevent brake-line failures that increase the risk of a crash.
