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.

370,000 new Silverado and Sierra pickups recalled over fire risk

General Motors announced late Friday that it will recall around 370,000 Chevrolet Silverado and GMC Sierra fullsize pickups from the 2014 model year over a possible fire risk. The recall covers select 4.3-liter V6 and 5.3-liter V8 models, which can evidently suffer engine compartment fires due to the overheating of exhaust components. GM notes that the fire issue may be preceded by a check engine light and an "engine power reduced" message on the driver information display.
Thus far, GM is aware of eight fires stemming from this problem (although only three of those incidents affected customer-owned vehicles), and all of the fires were reported in areas with "very cold weather." GM is urging owners to not leave their vehicles unintended while idling. No injuries have resulted from the fires in question.
The Detroit-based automaker has pledged to start mailing out recall letters on January 16. The fix, which involves software reprogramming, is estimated to be a 20-minute repair, and will be made free of charge.

2021 GMC Yukon Denali First Drive | Finally living up to the Denali reputation

For most of its existence, the GMC Yukon has been a virtually identical twin to the Chevy Tahoe. It would have some exterior differences, maybe a couple of different features, but aside from the badging, you’d be hard-pressed to distinguish the two. That also applied to the supposedly more luxurious Denali trim level. This new generation of Yukon mostly continues the trend, but now the Denali stands out more. It gets a unique interior designed to bridge the gap between the Yukon and Cadillac Escalade, and includes high-end features such as the Yukon's otherwise optional 6.2-liter V8 and magnetic suspension with air springs. All of this combined lets the 2021 GMC Yukon Denali live up to its luxurious reputation. It's easily the version to get if your bank account allows. It really is the interior that makes the biggest difference. The entire dashboard and door panels are exclusive to not only the Yukon, but the Denali trim level specifically. The dash design is more squared-off and truck-like, but itÂ’s offset by the use of some excellent materials. Large portions of the dash are wrapped in leather with stitching. ThereÂ’s also a large panel of matte-finish open-pore wood, available in multiple colors, on the passenger side. Some metal trim and nicely textured knobs adorn the center stack. The doors get this wood and leather, too. The center console features some attractive, stylized stitching as an extra adornment. The result is a place that feels high-quality and luxurious, but not in a garish or flashy way. Sort of a utilitarian luxury, which fits the look and character of the Yukon Denali. There are aspects of the interior that are shared with other Yukons and Tahoes, though. You get the same slightly odd but perfectly usable push-button shifter, the 10-inch touchscreen infotainment system, 15-inch head-up display, dual 12.6-inch backseat screens, and the same amount of interior space. These are all good things. The infotainment system is responsive and easy to use, while also offering the same advanced trailering camera system that so impressed in the Chevy Silverado HD. The head-up display is also large and legible, and fortunately not cluttered with too much distracting information. The best part, however, is the amount of space.
