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 HD pricing announced

Just as with its Chevy twin, pricing for the 2020 GMC Sierra HD has been revealed. Unlike the Chevy, though, prices haven't dropped across the board. The ultimate base prices for the 2500 HD and 3500 HD are technically less than the 2019 models at $37,195 and $38,395 respectively, but that's because those are the reintroduced regular cab models. Matching up the body styles of the last year's cheapest Sierras with their new equivalents, and the prices have crept up a few hundred dollars. But the next highest trim level, SLE, drops in price by nearly $2,000 between equivalent trucks. Equivalent SLT trucks are up nearly $2,000 each, though, and the base Denalis have gone up by about $7,000. This is due in part to the 2020 Sierra Denali no longer being offered with two-wheel drive. Comparing the old and new four-wheel drive models, the price is still up by about $4,000. While the new Sierra HD is only more affordable than the last one in certain circumstances, they all feature more capability. The standard 6.0-liter gas-powered V8 makes an extra 41 horsepower and 84 pound-feet of torque than the old one for a total of 401 horsepower and 464 pound-feet of torque. The 6.6-liter diesel V8 still makes 445 horsepower and 910 pound-feet of torque, but it now gets a 10-speed automatic transmission. Maximum fifth-wheel towing has increased, too. For the 2500, that number jumps from 15,400 pounds to 18,500 in the new model. For the 3500, fifth-wheel towing goes from 23,100 pounds to 35,500 pounds for the new truck. And of course, you can get GMC's fancy MultiPro tailgate on the new Sierra HD. One final note on the Sierra HD's pricing: it has the highest base price of the full-size heavy duty trucks. The Ford F-250 Super Duty is the cheapest at $34,745 and is closely followed by the Ram 2500 at $35,090. The full range of GMC Sierra HD pricing is listed below: Sierra 2500 HD Regular Cab Sierra: $37,195 SLE: $41,595 Double Cab Sierra: $39,795 SLE: $43,595 SLT: $52,195 Crew Cab Sierra: $41,595 SLE: $45,395 SLT: $53,995 AT4: $59,295 Denali: $65,295 Sierra 3500 HD Regular Cab Sierra: $38,395 SLE: $42,795 Double Cab Sierra: $41,195 SLE: $44,995 Crew Cab Sierra: $42,795 SLE: $46,595 SLT: $55,195 AT4: $60,495 Denali: $66,495 Update: The estimation of price difference between 2019 and 2020 Sierra Denalis has been corrected. Additional clarification of Denali price changes has also been added.

NHTSA opens safety investigations into Toyota, GM and Honda crossovers

The National Highway Traffic Safety Administration is evidently keeping itself very busy these days, as the federal agency has just announced it is launching or renewing investigations into Toyota, Honda and General Motors crossovers.
2006-2008 model year Toyota RAV4 crossovers are under review for allegations of rear tie-rod rust which can result in failure. NHTSA also said it is probing some 35 complaints about 2005 Honda Pilot models with inappropriate activation of the vehicles' stability control system. The alleged malfunction can cause the vehicles to slow down or stop in bad unsafe situations. At the moment, NHTSA is reviewing a petition regarding the Pilot issue, a move that will determine whether it needs to open a full-blown investigation.
In addition, Saturn Outlook and GMC Acadia three-row crossovers built in 2007-2009 are getting looked at for "loss of low beam headlamp" function. One complainant said the wiring in his Outlook overheated and melted. NHTSA says it has received 415 complaints about the problem and a GM spokesman confirmed that the automaker already started a "Customer Satisfaction Program" in December to address the issue.
