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.

GMC Sierra EV AT4, Chevy Silverado EV Trail Boss caught in spy photos

We've known for a while now that GMC and Chevy have been working on AT4 and Trail Boss versions of their respective Sierra EV and Silverado EV pickup trucks. But we're getting our best look yet at them with these spy photos. They give us a better idea of what body changes there will be, as well as a close-up of the tires, giving us their size and type. Some basics of off-road trim levels are obvious to spot. Both trucks feature bright red recovery hooks up front. But beyond that, there isn't much different from the outside of either truck compared to the base examples of each. The front bumpers are basically the same profile as the base bumpers, with the exception of the recovery hooks. The Silverado has natural black plastic fender flares, whereas the GMC has body color examples with integrated marker lights. They both get the same standard side steps, and the rear bumpers also appear unchanged. Each of these is equipped with the MultiPro/Multi-Flex tailgate. Chevrolet Silverado EV Trail Boss prototype View 14 Photos Really the biggest change appears to be in the wheels and tires. Each of them have unique designs, but they have the same dimensions. They're 18-inch wheels with 285/75R18 tires. That comes out to just shy of 35 inches in diameter, a good size of tire for an off-roader — and note how it doesn't even look all that large on such big trucks. Said tires are Goodyear Wrangler Territory AT all-terrains. The gas-powered trucks come with slightly narrower (275) mud-terrain versions as standard. Both of these trucks should start somewhere below the range-topping first edition models the two brands are currently marketing to the public, which hover between $95,000 and $110,000 depending on specification. The Silverado WT does start at just under $80,000, and we would expect the Trail Boss and the Sierra EV AT4 to come in somewhere above that, possibly between $85,000 and $90,000. Specifications are a mystery. It seems likely that at least the Silverado will get the WT's dual motors with 510 horsepower and 615 pound-feet of torque. The GMC could potentially get the more powerful motors making 754 horsepower and 785 pound-feet of torque as a way to differentiate itself, though this is speculation. The 204-kWh battery pack is probable, though there are rumors that at least GMC is going to start offering a smaller, more affordable 170-kWh pack that could be an option.

Chevy Colorado configurator goes live as GM touts fuel efficiency

While the news of today is destined to be dominated by a certain plucky Japanese roadster, props to Chevrolet and GMC for announcing its own significant bit of news about their newest pickup twins, the midsize Colorado and Canyon. The two GM-owned brands announced that the twins' 3.6-liter V6 will return up to 26 miles per gallon on the freeway.
To get such efficiency from the 305-horsepower mill, you'll need to live without four-wheel drive and be okay with a max city fuel economy of 18 mpg. The combined rating for the 2WD model sits at 21 mpg. Adding four-wheel drive drops the city and combined ratings by one mpg, while the highway rating dips from 26 to 24 mpg.
As for the twins' eagerly anticipated 2.8-liter diesel engine, it's destined for model year 2016, meaning we've got a ways to go before its efficiency and output are certified.
