5 things we love about the 2019 GMC Sierra AT4

NEW YORK — The 2019 GMC Sierra AT4 proves that GM's upmarket truck and SUV brand is getting serious about offering rough-and-tumble capability to rival the Ford F-150, Toyota Tundra, Ram 1500 and Nissan Titan. Until the Sierra AT4 rolled onstage at a media event in lower Manhattan, prior to this year's New York Auto Show, the GMC brand had been more focused on luxury touches like fancy chrome wheels and posh interiors — no surprise, considering the upscale SLT and Denali trim levels account for the vast majority of GMC sales. So now GMC wants to get muddy and adventurous? Well, yes and no. The AT4 adds hardware that'll take truck buyers off the beaten path, though this GMC isn't anywhere close to being a Spartan, no-frills work truck. To better explain, let's look at five key features we love about the 2019 GMC Sierra AT4: More than stickers and chrome The Sierra AT4 isn't a cynical marketing ploy, there is some true all-terrain toughness built into this pickup truck. A factory-installed lift kit raises the AT4 by two inches, while Rancho monotube shocks, a locking rear differential, a two-speed transfer case and standard all-wheel drive prove this GMC can dare to venture off paved surfaces — though you might risk getting mud and muck on the truck's handsome 18- or 20-inch alloy wheels. Power and economy The Sierra AT4 comes standard with a 5.3-liter V8 coupled to an eight-speed automatic transmission. In the standard Sierra 1500, this engine produces 355 horsepower. GMC didn't mention engine specs here in New York, though it's possible the AT4 might get a small power bump. This engine should be plenty for most truck buyers, though GMC offers two tempting alternatives. These include a turbo-diesel 3.0-liter inline-six, along with a 6.2-liter V8. Both motors are paired to stop-start fuel-saving systems, along with a new 10-speed automatic transmission. Carbon fiber cool factor The GMC Sierra's available carbon-fiber cargo bed, called CarbonPro in GMC-speak, trims 62 pounds of weight, as compared to a traditional all-steel bed. This slick feature uses carbon composites for interior panels and, judging from GMC's videos of burly bricks and huge hammers being thrown into a CarbonPro cargo bed, it should prove more than up to the task of ... well, having someone throw bricks and hammers into the cargo area.

GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.

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.
