摘要

What's New: New for 2020, with a payload of 5,607 pounds and the ability to pull north of 30,000 pounds when equipped with a gooseneck, the GMC Sierra 3500 HD Denali is a land-dwelling tugboat moonlighting, surprisingly, as an off-roader. Our tester came with the familiar LP5 Duramax powerhouse, good for 445 horses and 910 lb-ft of torque, bolted to a freshly revamped and Allison-badged 10L1000 10-speed automatic transmission. Engineers tackled issues of heat generation and power loss in the transmission by bypassing the torque converter and, when Tow/Haul mode is selected, using First gear to get every lb-ft of the truck's torque to the ground in demanding towing situations. Power is then routed through the MP3025 transfer case and its Autotrac system, an "industry first" for the heavy-duty segment. Brawnier driveshafts move the power into the rear differential and its gargantuan 12-inch ring gear before the dual rear wheels deliver it to the ground.
