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.

2015 Chevy Silverado, GMC Sierra can tow up to 12,000 pounds

Think back to the launch of the 2014 Chevrolet Silverado. At the time, General Motors happily trumpeted that its fullsize pickup could tow up to 11,500 pounds when properly equipped - impressive stuff, no doubt. But now, revised tow rating practices have been put into place, called SAE J2807. And with these new methods of testing, GM can now officially rate both the Silverado and its GMC Sierra twin as being able to tow up to 12,000 pounds.
Of course, not all Silverado and Sierra models are capable of this feat. In fact, because of SAE J2807, most of the truck models have actually had decreases in tow ratings from the 2014 to 2015 model year. For example, a 2014 Silverado Crew Cab with the 5.3-liter V8, 5.7-foot box and 3.73 rear axle was rated at 11,200 pounds in 2014, but has since been reduced to 10,800 in 2015. Same goes for the Sierra.
But for 2015, both the Silverado and Sierra can be had with a more powerful 6.2-liter V8, as well as a Max Trailering Package that includes a 9.76-inch rear axle, heavy-duty rear springs, revised shock tuning, improved cooling and a new trailer brake controller. There are also four- and seven-pin, bumper-mounted connectors, a trailer hitch (duh), and a G80 locking rear differential. This configuration, with either model, is the only way you can actually tow 12,000 pounds.
