As GM Authority has obsessively covered in the past, the refreshed 2025 GMC Yukon is poised to introduce a wealth of updates and changes over the preceding 2024 model year. Among these will be a diesel engine option for the off-road-capable 2025 GMC Yukon AT4. Prior to the upcoming 2025-model-year refresh, the GMC Yukon AT4 was available exclusively with a gasoline power unit.
According to GM Authority sources, the upcoming 2025 GMC Yukon AT4 will offer the 3.0L I6 LZ0 turbodiesel Duramax engine, the same diesel engine found under the hood of the 2023-and-newer Chevy Silverado 1500 and GMC Sierra 1500, not to mention the refreshed 2025 Chevy Suburban and 2025 Chevy Tahoe. Compared to the preceding 3.0L I6 LM2 turbodiesel Duramax, the LZ0 features new steel pistons with a revised combustion bowl, a retuned turbo compressor, new fuel injectors, and improved temperature control features. These advancements not only boost performance, but also enhance the overall efficiency of the engine. Output is rated at 305 horsepower and 495 pound-feet of torque, an increase of 10 percent and 7.6 percent, respectively, compared to output figures for the outgoing LM2.
In addition to the new LZ0, the 2025 Yukon will continue to offer a pair of gasoline engine options, namely the naturally aspirated 5.3L V8 L84 gasoline engine, and the naturally aspirated 6.2L V8 L87 gasoline engine, with engine availability dependent on the trim level selected.
Compared to the rest of the lineup, the 2025 Yukon AT4 will continue to feature several trim-exclusive features, such as a distinctive grille design, red tow hooks, a unique front fascia, all-terrain tires, and skid plates, enhancing the vehicle’s off-road capability, as well as its visual appeal.
Inside, the refreshed 2025 Yukon will sport a pair of large screens – a 15-inch infotainment display and an 11-inch driver information screen – aligning with what is offered in the GMC Sierra EV and the 2024 GMC Acadia.
Production of the refreshed Yukon will continue at the GM Arlington plant in Texas, with the GM T1 platform once again providing the underpinnings.

What % of at4 yukon owners take it Offroad? I’m going with 1% or less. Those skid plates must feel useless. What a horrible life they live.
I don’t know why rear independent suspension arms are so close to the ground like a conventional sedan ? It’s way too exposed to eventual damages off road.
Very few owners of AT4 / Z71 will use these vehicles offroad anyway, Ford & GM SUV’s aren’t hard-core offroaders like a Toyota Land Cruiser or even a Sequoia.
Jake this is a great comment, keep up the good work. How long did it take you to extrapolate all of the data on SUVs that go off-road? Can you define “offroad?” Is it, a dirt road? Any unpaved road? 2-track? Sand? Mud?
