2023 GMC Yukon Denali Ultimate comes with more style, most everything else

First introduced on the Sierra line, the even more luxurious Denali Ultimate trim is coming to the 2023 GMC Yukon. It includes nearly every available feature for the regular Denali as standard, plus some unique design features. The Denali Ultimate is distinguished by its dark chrome grille and badging, features that cannot be added to any other Yukon model. It also gets the largest wheels yet for the Yukon: 22-inchers with painted, machined and polished sections. The interior is more impressive. Most of the surfaces are covered in leather, real wood and aluminum trim. The seat backs and the wood trim have topographical maps of Mount Denali. Metal badging is even added to the seat backs with the special trim level's name. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. As for features, the Denali Ultimate comes with basically everything that's standard as well as what's usually optional on the regular Denali including magnetic shocks, huge screens, an 18-speaker sound system and massaging seats, among others. So this is one of the rare times where it actually is easier to list what's either an additional feature or just a preference. Naturally you get a choice of colors, and the trim level can be added to either the shorter Yukon or the longer Yukon XL. The standard engine is the gas-powered 6.2-liter V8 with 420 horsepower and 460 pound-feet of torque. The 3.0-liter turbodiesel straight-six is an option with 277 horsepower and the same amount of torque. Both are coupled to a 10-speed automatic and four-wheel drive. Super Cruise with towing and automatic lane change capabilities is another option, a rear-seat entertainment system and a towing package. And that's it. Pricing hasn't been announced, but it's pretty clear this will be the most expensive Yukon trim. The final numbers will be coming this June. Deliveries begin this fall.

GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.
