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 recalling 22K Silverado and Sierra trucks for seat issue

General Motors will recall 21,721 of its new 2014 Chevrolet Silverado and GMC Sierra pickups over front seats that could move if the vehicle is hit from behind. Affected vehicles all feature manual adjustments for the two front seats, according to a report from Automotive News.
Of the nearly 22,000 vehicles covered under the action, the overwhelming majority - 18,972 -- were sold in the United States. A further 2,575 were sold in Canada, while 103 were shipped south of the border to Mexico. Finally, another 71 were sold outside North America altogether. As of right now, there are no reports of injuries due to the defect.
Naturally, Chevy and GMC dealers will make the repairs free of charge, although it's not clear as of this writing if GM will be notifying owners or just addressing the issue at the truck's first service.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
