2024 GMC Sierra 1500 AT4X makes Duramax diesel standard

Changes are afoot for the 2024 GMC Sierra 1500 lineup. The one ringing the biggest bells for the off-roading crowd is the engine swap headed to the AT4X trim. Right now, if you want an AT4X you've got Hobson's choice of engines: The 6.2-liter EcoTec V8 with 420 horsepower and 460 pound-feet of torque. Next year, the 3.0-liter Duramax turbodiesel inline-six that's standard equipment on the AT4 and Denali Ultimate trims becomes the standard engine on the AT4X. The oil-burner makes 305 hp and 495 lb-ft., sent through the same ten-speed automatic the 6.2 V8 is yoked to. GM said around 20% of buyers have checked the Duramax box when buying a Sierra 1500 since the automaker released the upgraded engine for the 2023 model year — it's also offered on the SLE, Elevation, SLT, and Denali trims. The percentage should grow thanks to the diesel's low-speed grunt being one of the best "force multipliers" when traipsing over and through particularly challenging corners of the woods. The 6.2-liter will take the exhaust note crown over the diesel after the introduction of an active exhaust system with a Sport mode exclusively for the 6.2. Assuming no more changes to engine lineups before the 2024 Sierra arrives, the SLT, AT4, Denali, Denali Ultimate, and AT4X will have access to the active exhaust option.   GM Authority says the Duramax is getting another maximal friend in 2024, too. The 2.7-liter Turbo High-Output four-cylinder makes 310 hp and 430 lb-ft and is standard equipment on the entry-level Pro trim. the SLE, and Elevation trims will be renamed "TurboMax," which sounds like an Autobot, and that's not a bad thing. GM applied to trademark the name in January. The new moniker is headed to the Chevrolet Silverado as well, and we'd bet on exterior badging to let the world know.  Elsewhere around the Sierra, there will be two new exterior colors, Downpour Metallic and Thunderstorm Gray, mixable and matchable with two new aluminum wheel designs. And between those wheels, power retractable steps will be available for the Denali, Denali Ultimate, AT4 and AT4X trims. We'll be waiting to see how the steps differ from the GMC MultiPro Power Steps available now for $1,195.  Related video: This content is hosted by a third party.

GM recalls half-million full-size SUVs to address seatbelt issue

GM is recalling its redesigned full-size SUV models to address improperly riveted mounts securing the third-row seatbelts that may fail in the event of an accident. The population includes the 2021-2022 Cadillac Escalade and Escalade ESV, 2021-2022 Chevrolet Suburban and Tahoe, and 2021-2022 model year GMC Yukon and Yukon XL, for a total of 484,155 vehicles. "Operators at the supplier’s manufacturing plant may have not properly followed manufacturing processes and inadvertently missed the rivet forming operation," GM said in its defect report to NHTSA. "In certain of these vehicles, the rivet that retains the buckle to the mounting bracket in the left or right side third-row seatbelt buckle assembly may not have been properly formed during the manufacturing process. If the third-row seatbelt assembly is not properly riveted, it may not properly restrain occupants in a crash, increasing the risk of injury." Fortunately, the fix is relatively simple. GM service technicians will inspect the rivets on the rear seatbelt buckle assemblies and replace the entire unit if the rivets are not to spec. Dealer notifications have already been distributed; owners should receive notice start in September. Related video: Cadillac Chevrolet GM GMC Ownership Safety SUV

2016 GMC Sierra Denali Ultimate wants to take even more off the top

What do you do when getting to the top of Denali isn't enough? You create a higher peak called Denali Ultimate. That's what GMC has done with the 2016 Sierra, the new Sierra Denali Ultimate adding even more content and showing off the truck's refreshed face and new Denali grille. The reasoning behind this truck is perfectly sane. GMC says that in 2013 it had zero percent of the premium light-duty truck market; since that time, the brand says the segment (with an average transaction price beyond $55,000) has grown by a factor of ten, and the Sierra Denali has given GMC a 15.5-percent share. When it goes on sale in in the first quarter of next year, it can be optioned on the four-wheel drive 1500 Crew Cab with either the five-foot-eight or six-foot-six-inch bed. Standard equipment includes a sunroof, Lane Keep Assist, automatic headlights, Tri-Mode Power Steps, chrome tow hooks, and 22-inch wheels. The press release below has more. GMC Sierra Denali Ultimate: The Pinnacle of Premium Unique 22-inch wheels, expanded package of standard content drives exclusivity DETROIT, Tuesday, Nov. 17, 2015 – GMC is taking the range-topping style, craftsmanship and capability of the Sierra Denali even higher with the 2016 Sierra Denali Ultimate. It builds on the Sierra Denali's already class-leading attributes with a package of precision-crafted features designed to elevate its comfort, design and capability in the growing premium niche of the full-size truck market. GMC introduces the Sierra Denali Ultimate today, ahead of its public debut at the Los Angeles Auto Show. It goes on sale late in the first quarter of 2016. "The Sierra Denali has helped drive the growth of premium portion of the light-duty crew cab segment," said Duncan Aldred, vice president of GMC Sales and Marketing. "This truck is the ultimate expression of the Sierra Denali with greater emphasis on the bold and refined presence and advanced features that make Denali models synonymous with precision and exclusivity." Thanks in large part to Sierra Denali, which was redesigned in 2014, GMC commands 15.5 percent of the premium full-size truck segment, where average transaction prices exceed $55,000. The segment has nearly doubled in 2015 and grown tenfold since 2013, when GMC had zero percent of the market. In fact, Sierra Denali has helped GMC earn a higher share of the premium portion of the light-duty crew cab segment than of the overall full-size pickup segment.
