GM 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.

2022 GMC Sierra gets overhauled interior, new Denali Ultimate and AT4X

GMC Sierra's 2022 update is here, boasting a ground-up interior redesign, an updated Super Cruise package with trailering support, and two new trims aimed at very different buyers. While the GMC Sierra's bones are undeniably good, its interior has really held it back from our full-throated support in recent years. The pricier trims of the refreshed 2022 model may well erase those shortcomings entirely.  Hot on the heels of its revamped platform mate, the 2022 Chevrolet Silverado, the new Sierra arrives with a similar suite of upgrades, plus a few items that will remain exclusive to the fancy-pants Sierra for now, like Enhanced Super Cruise with available automatic lane-change and trailering mode. As with the Silverado, the Sierra's 2.7-liter four-cylinder gets an upgraded block and internals, allowing for a higher torque output (420 pound-feet), which means it makes even more torque than the 5.3-liter V8. Diesel models also enjoy some chassis upgrades that allow for the fitment of GMC's Max Tow package. That allows a diesel Sierra 1500 4x2 to handle 13,200 pounds and the 4x4 model to tow up to 13,000 even.  Still, the 2022 Sierra's most noteworthy improvements are to be found inside, and what better way to showcase an upgraded interior but with a new, range-topping luxury trim? Say hello to the 2022 GMC Sierra Denali Ultimate.  This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. 2022 GMC Sierra Denali Ultimate unveiled Denali represents a huge chunk of Sierra sales, and when your branding is based around upscale sophistication, you sure want to put your best foot forward at the top of the pricing structure. GMC wasn't quite there with the outgoing Sierra Denali, but the new Denali Ultimate may just be the ticket to one-upping the likes of the swanky Ram 1500 Limited.  This is the no-holds-barred, all-options-checked model that really makes GMC money. The 6.2L V8, 10-speed automatic and Super Cruise are standard on Denali Ultimate. All of the leather and wood elements visible here are real (seriously, you can touch them and everything). There's also a faux suede headliner, 16-way power-adjustable and massaging front seats, a 12-speaker Bose system and a 15-inch color HUD included.  GMC included several unique elements for Ultimate, including topographical maps and the latitude and longitude of Mount Denali formed into various interior trim pieces.

GM faces possible class action lawsuit over 8-speed transmission

General Motors has been hit with a class-action lawsuit from owners who allege the eight-speed automatic transmission found in several rear-wheel-drive Chevrolet, Cadillac and GMC models between the 2015 and 2019 model years has a defect that causes the vehicles to hesitate and jerk when accelerating or slowing down. The lawsuit was posted to ClassAction.org and spotted by GM Authority. Problems with GM's Hydra-Matic 8L90 and 8L45 transmissions have been well-documented on Internet forums and via complaints filed with the National Highway Traffic Safety Administration, with many reporting damage to their vehicles. The lawsuit was first filed in December in U.S. District Court for the Southern District of Florida but appears to have been transferred recently to New York. Autoblog sought comment from Theodore Leopold, the lead attorney for the plaintiffs. "These transmissions have a common defect," the complaint reads. "Drivers attempting to accelerate or decelerate their cars feel a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." The problem also occurs when the vehicles accelerate in a single gear, without shifting, the plaintiffs allege. "Drivers have reported that the shift is sometimes so violent, they feel as though they have been hit by another vehicle." The problem is believed to center on the transmission, torque converter or both. The complaint says it causes undue friction, causing hydraulic systems and gears to function improperly and sometimes leaves metal shavings throughout the transmission, leading to costly repairs and replacement of parts or the entire transmission. It says GM has known about the problems since shortly after it introduced the transmissions, and has issued 13 technical service bulletins, none of which have resolved the problem. GM declined to comment on the lawsuit. The plaintiffs say GM should have warned consumers about the issues and covered repairs under each vehicle's three-year/36,000-mile bumper-to-bumper warranty. They're seeking statewide classes in at least six states: California, Florida, Illinois, New York, Oklahoma and Texas.
