Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.

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.

New GMC feature reminds drivers to check for kids in hot cars

We see the stories every summer: Dozens of children die from heat stroke every year after being left inside hot cars. GMC has introduced a feature in the 2017 Acadia in an effort to help curb the problem. Simply called Rear Seat Reminder, it alerts the driver if the vehicle suspects someone might have been accidentally left behind. GMC's alert will trigger under certain circumstances. Five chimes will sound and a warning will display if the rear doors are opened and closed within 10 minutes of the vehicle starting or if those doors are opened while the vehicle is running. The system does not sense items or people in the rear seat like the front passenger seat would to trigger the airbag. Warnings will be displayed regardless of interior or exterior temperature; while the summer months are the deadliest, leave-behind deaths occasionally occur during cold weather. Drivers should be aware that temperatures in vehicles can quickly rise to dangerous levels, even if the ambient temperature seems cool and comfortable. View 23 Photos Unfortunately, a large percentage of children are intentionally left in cars. A negligent caretaker, whether it be a parent, grandparent, or babysitter, can leave a child behind while they go to work or run an errand, not expecting any problems. Some children unintentionally trap themselves in cars while playing in the cabin or trunk. The Acadia's system is unlikely to prevent these scenarios. While we believe that GMC should be commended for making an effort to put an end to these tragedies, we're not certain how effective the system might be until driver education improves. It's also possible drivers will come submit to warning fatigue and begin to ignore the messages. That said, if this software-based solution prevents just one death, it was worth the effort.
