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.

2019 GMC Sierra 1500 prototype shows off differences from Silverado

Now that the new Silverado has made its debut, we're awaiting the reveal of its mildly restyled twin, the GMC Sierra 1500. While it likely won't be that different as far as capability and major equipment are concerned, we are looking forward to seeing what design changes it will have. Based on these recent spy shots, the changes will be mild, but still enough to make it visually distinctive. One of the more obvious differences will be in the front fascia treatment. Unlike the Silverado's grille that's level with the top of the headlights, the GMC's will rise above the lights, which will also yield a slight drop on each side of the hood to meet the lights. The grille is quite tall, extending far below the headlights, too. We can make out, behind some mesh, two dips on the outer edges of the grille that give the Sierra a more menacing frown. Large foglights are also found right near where the scoops for the wheel air curtains, and the headlights are unified on the edges, rather than split on the Silverado. Along the sides, the sheet metal looks relatively unchanged. At some angles, we can make out the distinctive shoulder line from the Silverado that runs up to about the rear mirrors where it stops to make room for another crease that rises up from somewhere in the middle of the front doors to lead to the front. The wheel arches are decidedly different from the Silverado's though. While the Silverado has fairly rounded arches, the Sierra's have a rear-slanted bevel to the fronts of the arches and a rounded 90-degree corner at the rears. There isn't much we can tell about the rear except for the taillights. They're quite large, and unlike the Silverado's, there aren't any areas where the sheet metal intrudes. It also appears that the tops of the taillights extend farther forward into the bed sides than the Chevy's. Because the Sierra has almost always been a mechanical twin of the Silverado, we expect it to offer the same 5.3-liter and 6.2-liter V8s, as well as the new 3.0-liter diesel inline-6. Also, being a GMC, it will likely have a flashy, chrome-laden Denali trim level. We also will see the fully revealed model soon, as Automotive News reports the debut will be on March 1.

GM confirms 2015 Silverado, Sierra to get 8-speed automatic

When viewed alongside the next Ford F-150 and the Ram 1500, there is one thing that seems to be missing from the Chevrolet Silverado and GMC Sierra. Where the F-150 will rely on turbocharging and aluminum architecture and the Ram sports an eight-speed automatic and an air suspension, the General Motors twins lack a big, calling-card feature. They're very good, very refined trucks, but one could argue that they're not terribly innovative.
And while it might not be as flashy a feature as air suspension or a lightweight skin, the Silverado and Sierra will get their own eight-speed automatic for 2015, a transmission that will be paired with the company's Ecotec3 6.2-liter V8. The new cogswapper will also find its way into the GMC Yukon Denali, but for now, there's no indication why the Cadillac Escalade, Suburban, Tahoe and standard Yukon are being left out.
According to GM, the new gearbox is about the same size and weight as the current Hydra-Matic 6L80 six-speed. By the time the new powertrain combination enters production late this year, the EPA will almost certainly have gotten around to certifying the vehicles' fuel efficiency. Until then, feel free to speculate. The current Silverado with the 6.2 and six-speed auto returns 14 miles per gallon in the city and 20 on the highway. How much do you think the eight-speed will improve those figures? Scroll down for the official press blast from General Motors, and then head into Comments.
