2020 GMC Sierra HD caught in double-cab, low-trim gas-engine guise

Naturally when the 2020 GMC Sierra HD was revealed, GMC picked the flashiest, most-impressive Denali model with the big crew cab configuration and diesel engine. But obviously not all will be equipped that way, so it's exciting to see a lower trim model like the truck above. This 2020 GMC Sierra HD is a more modest SLT trim model equipped with the gas V8 and lacking the MultiPro tailgate. Styling doesn't take a hit with the shorter shape, and arguably, it looks more athletic without so much metal between the wheels. The length is the only real difference, with the rest of the sheetmetal just as chisled on the bigger version. Interestingly, this gas-powered Sierra HD still has a big hood scoop from its diesel sibling. On the current GM heavy duty trucks, only the diesel models get a scoop, and it's specifically for getting more cool air to the intake. The Silverado HD may continue this differentiation, but GMC is clearly keeping it for all models. When the Sierra HD goes on sale this summer, it will be available with either a 6.2-liter gasoline V8 like in this truck, or a 6.6-liter turbodiesel V8 making 445 horsepower and 910 pound-feet of torque, the same as the current model. All models get bedside steps, and the MultiPro tailgate is available either as standard or an option with all trims. Related Video: This content is hosted by a third party.

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.

GMC's electric, 1,000-horsepower Hummer SUV makes a surprise appearance

We knew the GMC Hummer pickup would spawn an SUV, but we didn't expect to see it so soon. It quietly appeared in a marketing presentation about electric cars that General Motors streamed online in November 2020. The camera never focused on the SUV, there was always an executive sitting in front of it, but we see enough to tell it's closely related to its pickup sibling. Both battery-powered off-roaders are nearly identical from the tip of the front bumper to the edge of the rear doors. The SUV's overhang is a little bit shorter than the pickup's, though there's presumably space for a third row of seats. Its rear end doesn't appear in the presentation. Nothing suggests GMC made major powertrain changes to the SUV, so it's likely identical to the truck underneath the sheetmetal. Range-topping models will receive three motors zapped into motion by a 24-module Ultium battery pack. Motorists will have 1,000 horsepower and approximately 350 miles of driving range to play with. GMC plans to start building the Hummer pickup in late 2021, and the SUV might not enter production until early 2022. We expect pricing will initially start above $100,000, but more affordable variants will gradually join the lineup during the first half of the 2020s. When it lands, the off-roader will compete directly against the Rivian R1S. General Motors will invest $27 billion into electric and autonomous cars by 2023. Its portfolio of EVs will also include a Silverado-sized pickup, a crossover based on the Bolt, and a high-end Cadillac crossover named Lyriq. "We want to be number one in EVs in North America," affirmed company boss Mary Barra.
