2020 GMC Sierra HD offers loads of tech

The 2020 GMC Sierra HD has finally been revealed, and it's a heck of a lot more subtle than the Silverado HD. Whereas the Chevy went with a wildly exaggerated version of the split grille and headlights the truck is known for, the Sierra simply builds on the 1500 model's design with an expanded grille that doesn't appear to be as tall or wide as the Chevy's. That's not to say it looks unimpressive, though. It's still got a massive fascia, it's just not as extreme as the one with a bowtie on it. With the Sierra's unveiling, we get more details about the powertrains available on the heavy duty GM trucks. The 6.6-liter turbocharged Duramax V8 makes 445 horsepower and 910 pound-feet of torque. That's the exact same output as the engine in the old models. But this time, the engine will be mated to an Allison-branded heavy duty version of the GM 10-speed transmission. A gas engine will also be available, but GMC hasn't revealed details on it yet. The new Sierra boasts a range of new features, some that are unique to it, and some shared with the Silverado. A shared feature is the new steps in the bed sides that are standard on all Sierra HD models. Unique to the brand is the MultiPro tailgate with fancy drop-out step. This tailgate will be available on all trims, and it's standard starting with the mid-level SLT. There are some useful visibility features being shown on the new Sierra, too, such as an available trailer camera system with 15 possible viewpoints, and it can virtually show the rear view on the screen as if there wasn't a trailer in the way. GM's rear-view mirror screen also makes an appearance. An AT4 off-road trim will be available on the new Sierra HD. It has slightly different styling with dark grilles and trim. Off-road upgrades include reworked springs and shocks, skid plates, standard all-terrain tires and a locking rear differential. Pricing has not yet been announced, but the truck goes on sale this summer. Details on prices as well as further specifications will likely be announced near the on-sale date.

Regular-cab, short-bed Chevy Silverado Trail Boss pickup looks great

For all the wild popularity of full-size pickups, there's one configuration that U.S. buyers are no longer offered: the regular-cab, short-bed truck. Interestingly, however, GM still does make this configuration, and both the Chevrolet Silverado and the GMC Sierra are offered with it — in the Mexican market. That body style, however, is available solely in ultra-basic work-truck form. But a custom wheel shop, JC Wheels in the Mexican city of Culiacan, has converted one of these Silverados to Trail Boss trim, and we're digging the result. The sporty shorty Silverado Trail Boss comes to our attention via GM Authority, after the shop posted it on their Instagram feed. The shop added a 3-inch lift, assist steps, Chevy alloy wheels, a Trail Boss front fascia including red tow hooks, and Trail Boss badging. They also added dark window tint, which seems like a good idea in sunny Mexico. In the U.S., the Silverado Trail Boss isn't offered at all in regular-cab form; it only can be had as a double cab or a crew cab, the latter with a choice of a short bed or standard bed. But size is often a hindrance for trucks that actually get driven on trails, where this regular-cab, short-bed variant's smaller wheelbase would be an advantage. Beyond that, the Trail Boss upgrades keep this configuration from looking like a basic-spec machine. That's even more true of the same outfit's previous efforts: the conversion of the GMC Sierra regular-cab, short-bed pickup into a Denali. With so many buyers choosing pickups as personal-use vehicles, it's not hard to think that this configuration could find an audience here. But the key would be to do as this Mexican firm has done and offer it in the desirable off-road and luxury trims, rather than as a basic work truck. Would you buy one? Sound off in the comments below. The next step would be to use this configuration as the basis of a full-size, two-door SUV, in the mold of the classic Chevy K5 Blazer and GMC Jimmy.

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.
