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.

2017 GMC Acadia adds four-cylinder and All Terrain model

General Motors has officially started the process of updating its long-in-the-tooth fullsize CUVs by unveiling the second-generation GMC Acadia at the 2016 Detroit Auto Show. While the Acadia is 700 pounds lighter, it's also shorter and narrower, which means it's not quite the people mover it used to be. You'll no longer be able to haul eight passengers, although there will still be five-, six-, and seven-passenger offerings. While families might not be thrilled with the loss of a seat, the lighter weight is a net win. Not only will the V6 model feel more powerful and efficient – in addition to the lower curb weight, there's a new, 310-horsepower engine – but it will also likely be more economical. GM estimates the front-drive V6 will return 25 miles per gallon on the freeway, compared to 24 mpg for the current front driver, but city fuel economy remains pegged at 17 mpg. In a move we're not entirely sold on, though, the Acadia will also adopt a four-cylinder engine, and no, it's not GM's highly regarded 2.0-liter turbo. Instead, you'll be able to order this 4,000-pound CUV with a 2.5-liter, 194-horsepower four-cylinder. What it won't be able to provide in straight-line speed, it will make up for with fuel economy. GM is wagering the front-drive, four-cylinder Acadia will net 22 mpg in the city and 28 on the highway. Both engines are paired with a HydraMatic 6T75 six-speed automatic. A new All Terrain model is said to be optimized for wet, snowy and icy conditions, and its drive mode selector removes the Off Road selection in favor of All Terrain. We have live images of both the new Acadia Denali, as well as the new-for-2017 All Terrain model, direct from the floor of the 2016 Detroit Auto Show. There's also a video of the full GMC press conference with reactions from our editors. Check them out.

2024 GMC Hummer EV SUV revealed, priced the same as the truck

Following up on the 2024 GMC Hummer EV pickup truck's big reveal back in October is the SUV variant. And it looks pretty much the way you would expect. From roughly the doors forward, it's the same as the blocky pickup. But the back half now has an enclosed cargo area, a full-door tailgate and full-size spare mounted to it. Besides the tweaked looks, the SUV is physically shorter. The full dimensions haven't been revealed yet, but the wheelbase is 8.9 inches shorter than the truck at 126.7 inches total. The overall length is likely reduced even further, since the tail is much shorter than the truck's with the rear wheels close to the bumper. Both of these changes will greatly improve breakover and departure angles, plus make the vehicle generally more maneuverable on and off road. GMC boasts that with four-wheel-steering, the turning circle is just 35.4 feet, about a foot and a half tighter than the truck. This content is hosted by a third party.
