GMC introduces off-road performance package for Sierra AT4

GMC is giving its off-road-focused Sierra AT4 pickup even more performance with some factory-installed upgrades. The package is called the AT4 Off-Road Performance Package. With it you'll get the 6.2-liter V8 engine upgrade, cat-back performance exhaust system, performance air intake and 18-inch aluminum wheels shod in Goodyear Wrangler DuraTrac tires. The upgraded performance comes in the form of extra power. Thanks to the bolt-ons, you gain 15 horsepower and 9 pound-feet of torque over the 6.2-liter in stock form. This increases output to 435 horsepower and 469 pound-feet of torque — not too shabby. This package is priced at $4,940, and available for order now. That's a hefty price for what amounts to some minimal bolt-on modifications you could easily do yourself. However, buying it through GM means you get to keep your warranty in place. The Sierra AT4 already has more off-road features than a normal Sierra 1500. You're getting a two-inch lift, four-wheel drive with two-speed transfer case, locking rear differentials, skid plates, Rancho off-road shocks and hill descent control. Both the wheels and tires are available as options already, but this package just bunches related stuff together. It'll be up to you to decide if an exhaust and intake are worth the extra dough.

2021 Chevy Silverado, GMC Sierra fuel economy to go down due to global chip shortage

Production of the 2021 Chevy Silverado and 2021 GMC Sierra is continuing, but the global semiconductor chip shortage is resulting in a mid-year change. Or rather, an omission.  Basically, the availability of cylinder deactivation for the 5.3-liter V8 will be significantly reduced, resulting in a reduction of 1 mpg combined for affected models. This applies whether that engine has the six- or eight-speed automatic, as well as to both the regular Active Fuel Management and the more advanced Dynamic Fuel Management cylinder deactivation systems. DFM does remain with the pairing of 5.3-liter V8 and 10-speed automatic that comes standard on the LT Trail Boss and High Country. "Due to the micro controller shortage, the components that control AFM/DFM in the engine control module (ECM) have been removed," GM spokesperson Michelle Malcho told Autoblog. She also indicated that the engines will still have the AFM/DFM hardware in place, but that GM will not allow activation of the systems in the future with an ECM change.  Malcho also confirmed to Autoblog that the Silverado and Sierra's other engines will continue to have AFM and DFM, including the 2.7-liter turbo inline-four, 4.3-liter V6 and 6.2-liter V8. In an earlier statement to Reuters, she declined to say the volume of vehicles affected. "By taking this measure, we are better able to meet the strong customer and dealer demand for our full-size trucks as the industry continues to rebound and strengthen," Malcho wrote Reuters in an email. The change runs through the 2021 model year, she said. Malcho told Reuters it would not have a major impact on the Detroit automaker's U.S. corporate average fuel economy (CAFE) numbers. "We routinely monitor our fleet for compliance in the U.S. and Canada, and we balance our portfolio in a way that enables us to manage unforeseeable circumstances like this without compromising our overall (greenhouse gas) and fuel economy compliance," she said. GM's fleetwide fuel economy in the 2018 model year was 22.5 miles per gallon and was projected to rise to 22.8 mpg for 2019, according to a report by the Environmental Protection Agency. To meet federal CAFE requirements, automakers like GM often use credits from either earlier years where they faced less stringent rules and performed better than the requirements or buy credits from other automakers. GM said last month the chip shortage could shave up to $2 billion from this year's earnings.

2022 GMC Acadia gets small changes, price hike

GMC put conspicuous effort into the 2020 Acadia, adding a few more embellishments this year. For 2022 the Acadia gets another nuanced rework, the most important change being the elimination of both the base SL trim and the 2.5-liter four-cylinder engine. The Acadia SLE, the next trim level up from the SL, this year offers the 2.5-liter four-cylinder and 3.0-liter V6 in front-wheel-drive guise. Next year, the only engine available for the front-driver SLE will be the 2.0-liter turbocharged four-cylinder. The spec rearrangement jacks up the Acadia's barrier to entry to $35,995 for the new base model, a $5,000 increase over 2021. There's some give-and-take in the details to even out the exchange. Buyers this year needed to step up to the SLE in all-wheel-drive trim to get access to the 2.0-liter, which started at $38,295, and keeps that price for next year. But SLE pricing only goes up by $900 to swap the 2.0-liter for the 2.5-liter, not much money for a lot more power. The 2.5-liter produces 193 horsepower and 188 pound-feet of torque, the 2.0-liter makes 230 hp and 258 lb-ft. One more cut sees the Acadia AT4 with the five-passenger cabin struck from the menu, six- and seven-passenger seating the only choices. And one more swap sees the $495 Red Mahogany Metallic premium exterior paint replaced by the $495 Light Stone Metallic. Upgrades include new 18- and 20-inch wheel designs, and all 2022 Acadias get the Pro Safety Plus package standard. That installs driver assistance features such as Automatic Emergency Braking, IntelliBeam headlights, Front and Rear Park Assist, Forward Collision Alert, and Rear Cross Traffic Alert. And Traction Select, GMC's name for road surface and terrain modes, is also standard across the lineup.  The 2022 Acadia entered production at GM's Spring Hill, Tennessee plant at the end of last month, the configurator is live now.
