Buyers interested in putting a new 2021 GMC Yukon diesel in their driveway will be happy to learn that next-generation Yukon models equipped with the latest oil-burner powerplant are now available to order, including both the standard Yukon model, and the extended-length Yukon XL.
As GM Authority covered previously, the new 2021 GMC Yukon diesel arrives with late availability following a debut back in January. Order books opened up October 29th, coinciding with orders for the new 2021 Chevy Tahoe diesel and 2021 Chevy Suburban diesel. Production for all three diesel-powered SUVs kicked off on a limited basis in November, albeit on a constrained basis.
The launch schedule for the 2021 GMC Yukon is now in its third and final phase, which includes all packages, trim levels, and the latest GMC Yukon diesel engine option as well.
As a reminder, the oil burner in question is the 3.0L I6 LM2 turbodiesel Duramax, which arrives as a new option with the latest next-generation 2021 GMC Yukon and Yukon XL. Output is rated at 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm, and the engine features direct injection and dual-overhead cams.
As GM Authority covered previously, the new diesel engine is not available with the latest 2021 GMC Yukon AT4, the nameplate’s rough-and-ready off-roader trim level, as the AT4’s unique front fascia obstructs the diesel engine’s intercooler piping.
In addition to the LM2 diesel engine, the 2021 GMC Yukon is also offered with the naturally aspirated 5.3L V8 L84 gas engine, which produces 355 horsepower and 383 pound-feet of torque, and the naturally aspirated 6.2L V8 L87, which produces 420 horsepower and 460 pound-feet of torque.
