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.

2023 GMC Sierra HD 2500 and 3500 will get more expensive

GMC Sierra HD pickups are about to get more expensive again after recently becoming more expensive, according to GM Authority. In July, GMC and Buick raised the prices on certain vehicles in their lineups anywhere from $975 to $1,675 by making the previously optional OnStar a standard feature. Next year, every GMC and Buick model will adopt the upgrade. The big boy Sierra HD gets the biggest increase, being $1,500 for three years of OnStar and the Connected Services Plan plus another $175 for to be "OnStar & GMC Connected Services capable." GMA says the MSRPs for the entire 2023 Sierra HD range will be increased $1,000 on top of that. After doing the math, though, we suspect the increase could in fact be anywhere from about $800 to at least $1,100 after factoring for OnStar. The GMC configurator rings up a price of $43,670 for an entry-level Regular Cab Sierra HD Pro 2WD, GMA says next year's price will be $44,770. GMA didn't break out the next year's destination charge, it's possible GMC is adding $1,000 to the MSRP and $100 to destination. We'll find out when official pricing is announced. GMA's table shows a price of $49,795 for the least expensive SLE trim, whereas the current configurator indicates the truck can be had for $47,295 — a $2,500 difference. The SLE configurator doesn't show any charges for OnStar the way the Pro trim does. So it's possible that after backing out a potential $1,675 for OnStar, the gravy on top is just $825. Not that your wallet will care where how the potato is being sliced when the potato costs an additional $2,500 no matter what. The least dear 2022 Sierra 3500 starts at $43,195 going by the configurator. GMA says that model will command $45,970 next year, a $2,775 difference. As with the 2500 HD SLE, the configurator doesn't show the OnStar charges for the base 3500 Pro trim; subtracting the $1,675 takes us back to the $1,100 difference that appears to be at the heart of all of this. If all goes to plan, the 2023 Sierra HD will give way to a heavily refreshed 2024 model with interior upgrades cribbed from the Sierra 1500. Spy shots reveal a reconfigured instrument panel with a larger infotainment touchscreen of a likely 13.4 inches among the interior tweaks. Related video: This content is hosted by a third party.

GM is the latest automaker accused of diesel emissions cheating

Volkswagen and Ram need to make room on the diesel-emissions bench for General Motors. America's largest automaker was accused in a lawsuit on Thursday of rigging hundreds of thousands of diesel trucks with at least three so-called defeat devices to ensure that the trucks would meet federal and state emission standards, even if they generated more pollution in real-world driving. According to the complaint, on-road emissions testing conducted for the plaintiffs found that Duramax-equipped trucks produced NOx pollutants, comprised of nitrogen and oxygen atoms, two to five times higher than legally permitted, and "many times" higher than their gasoline counterparts. The proposed class-action lawsuit was filed in federal court in Detroit on behalf of people who own or lease more than 705,000 Chevrolet Silverado and GMC Sierra pickup trucks fitted with "Duramax" engines from 2011 to 2016 model years. The lawsuit seeks remedies including possible refunds or restitution for lost vehicle value, plus punitive damages. It adds to legal problems for Detroit-based GM, which has already paid about $2.5 billion in penalties and settlements over faulty ignition switches linked to 124 deaths. GM joins at least five automakers whose diesel emissions have been scrutinized by regulators or consumers. They include VW, which has admitted to cheating; Mercedes-Benz parent Daimler; Fiat Chrysler Automobiles, Peugeot and Renault. GM spokesman Dan Flores called the claims "baseless," and said the trucks comply with US Environmental Protection Agency emissions standards and California's own tough standards. Shares of GM were down 69 cents, or 2.1 percent, at $32.50 in afternoon trading, after earlier falling to $31.93. The GM lawsuit was filed by several law firms, including Hagens Berman Sobol Shapiro, which helped reach multibillion-dollar settlements with VW on behalf of drivers and dealers. The case is Fenner et al v General Motors LLC et al, US District Court, Eastern District of Michigan, No. 17-11661. The named plaintiffs are Andrei Fenner of Mountain View, California and Joshua Herman of Sulphur, Louisiana. They said they would not have bought their respective 2011 Sierra and 2016 Silverado trucks, or would have paid less for them, had they known about the alleged rigging. Joseph Spak, an RBC Capital Markets analyst, in a research report said "negative publicity" from the lawsuit could drive buyers to trucks from Ford or even Fiat Chrysler's Ram.
