GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

How Chevy Silverado, GMC Sierra will take on the Ford F-150 profit machine

FORT WAYNE, Ind. — When General Motors engineers were developing the 2019 Chevrolet Silverado and GMC Sierra pickup trucks, some of them joined public tours of Ford's Dearborn, Mich., factory to watch aluminum-bodied F-Series trucks go down the assembly line. The redesign of the Ford F-Series trucks, launched in 2014, set a new standard for fuel economy and lightweight vehicle construction. But armed with stopwatches and trained eyes, the GM engineers believed they saw problems. "They had a real hard time getting those doors to fit," Tim Herrick, the executive chief engineer for GM truck programs, told Reuters. His team did more intelligence gathering. They bought and tore apart Ford F-Series doors sold as repair parts. Their conclusion: GM could cut weight in its trucks for a lower cost using doors made of a combination of aluminum and high-strength steel that could be thinner than standard steel, shaving off kilograms in the process. These pounds-and-pennies decisions will have major implications in the highest-stakes game going in Detroit: dominance in the world's most profitable vehicle market, the gasoline-fueled large pickup segment. What's more, GM is banking on strong sales of overhauled 2019 Silverados and GMC Sierras to fund its push into automated and electric vehicles — a business many investors see as the auto industry's long-term future. The risks are high given the hits automakers have taken from U.S. President Donald Trump's trade policies. Rising aluminum prices spurred by Trump's tariffs are driving up costs on the Ford's F-Series, while rising steel and aluminum prices likewise drag on GM results. GM also has a significant risk should the United States, Mexico and Canada fail to agree on a new NAFTA trade deal, given GM trucks built at its Silao, Mexico, factory could face a 25 percent tariff if NAFTA collapses. Major profit per truck Interviews with GM executives and a tour at its factory here in northwest Indiana provide a detailed look inside GM's plan for the most important vehicles in its global lineup. These big pickups are everything Tesla's Model 3 or Chevy's Bolt electric car is not. The mostly steel body is bolted to the truck's steel frame, rather than the one-piece body and frame electric vehicles. The majority of trucks will have a V-8 gasoline engine powering the rear wheels — like the classic GM cars of the 1950s. Some Silverados will have new four-cylinder engines, but there is no electric or hybrid offering as of now.

2024 GMC Canyon AT4X AEV Edition First Drive Review: The business-class Bison

McALLISTER, Mont. – Not far from MontanaÂ’s Ramshorn Peak is a beautiful body of water known as South Meadow Creek Lake. It sits just a hair below 9,000 feet and offers beautiful views of the surrounding highlands and — if youÂ’re lucky and the lighting is just right — a clear line of sight to Big Sky Country. To hear the locals tell it, you canÂ’t get there in a pickup truck. Apparently, to a GMC engineer, that comes across as an open challenge. And so I found myself in the two-horse town of McAlllister (not far from Bozeman), chilly in the fog of an early October morning, inspecting a line of GMCÂ’s midsize trucks in their hardest of hardcore variations. One half of the fleet was made up of the standard 2023 Canyon AT4X finished in a beautiful scarlet red; the other half, 2024 Canyon AT4 AEV Editions in a menacing gray that matched the dreary morning sky. Yep, that AEV. The Canyon AT4X is an already-capable little trail monster with all the off-road bells and whistles you could possibly ask for. ItÂ’s a virtual mechanical twin to the new Chevrolet Colorado ZR2, in fact, down to the 2.7-liter four-cylinder that produces 310 horsepower and a whopping 430 lb-ft of torque. Naturally, American Expedition Vehicles managed to turn that dial up to 11. More on that later. Canyon AT4X 3 View 32 Photos To the locals' point above, off-road trucks have existed for quite some time (just ask Marty McFly), but it has only been since their rise in popularity as mainstream commuters that the dedicated four-wheelinÂ’ pickup has really come into its own. The “you canÂ’t get there from here” Maine attitude at Bozeman latitudes betrays somewhat old-school notions about four-wheeling — and the fact that just about everybody in town owns some sort of ATV or side-by-side. The formula used to be pretty simple: You take the shortest SUV frame youÂ’ve got, add big stick axles to the front and rear, and then jack the thing up as high as you can without it falling over at the first sign of an incline. TodayÂ’s torque-monster engines have turned that on its ear. More torque means you can turn bigger tires, and what do bigger tires do? Well, among other things, they lift your truck off the ground. Shove enough tire under a truck and no matter where youÂ’re talking about, you can indeed get there from here. At its core, AT4X isnÂ’t groundbreaking.
