The 2024 GMC Yukon is set to introduce the fourth model year of the SUV’s fifth generation, dropping in mostly unchanged compared to the 2023 model year. Critically, the 2024 GMC Yukon was originally expected to introduce a mid-cycle enhancement (alternatively known as a refresh) with a long list of enhancements and changes, but this is no longer the case. As such, the 2024 GMC Yukon will continue to offer the 3.0L I6 LM2 turbodiesel Duramax engine, rather than the 3.0L I6 LZ0 turbodiesel Duramax engine expected originally.
For those readers that still need to catch up, the 2024 GMC Yukon was originally expected to introduce the new 3.0L I6 LZ0 turbodiesel Duramax engine as a replacement for the 3.0L I6 LM2 turbodiesel Duramax engine offered currently. The new diesel powerplant was set to drop in conjunction with the SUV’s 2024 model-year refresh, but new information has come to light indicating that the refreshed GMC Yukon will in fact debut for the 2025 model year, if not later. As such, the 2024 GMC Yukon will continue to offer the 3.0L I6 LM2 turbodiesel Duramax engine as the optional diesel powerplant.
The new 3.0L I6 LZ0 turbodiesel Duramax engine includes a number of upgrades over the 3.0L I6 LM2 turbodiesel Duramax engine offered currently, including a retuned turbo compressor, improved temperature controls, new steel pistons, and new fuel injectors. These upgrades help to boost output to 305 horsepower at 3,750 rpm and 495 pound-feet of torque at 2,750 rpm, which is a 10-percent increase in power and a 7.6-percent increase in torque compared to the 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm produced by the 3.0L I6 LM2 turbodiesel Duramax engine. The LZ0 is currently available on the 2023 and newer model years for the GMC Sierra 1500 and Chevy Silverado 1500 pickup trucks.
As a reminder, the GMC Yukon rides on the GM T1 platform, while production takes place at the GM Arlington plant in Texas.

I can’t figure out why GM doesn’t offer the Suburban in the large V8 Duramax Diesel Engine! They’re missing the boat!
because the HD suburban died like 15 years ago..
Because the 3/4 ton Suburban never sold well. Hard to justify building a product that very few people want or need. GM is not the only manufacturer that quit making 3/4 ton SUV’s. The LZO diesel will be plenty for most people as it actually has more power and torque than the early Duramax 6.6 from the early 2000s. Not to mention most people would prefer to get 30 MPG VS 20 MG that you will get with LZO and 10 speed.
I don’t get why they would do this
, why have 2 different platforms?? Why wait 2+ years to upgrade the engine that’s already been upgraded in the pickup?
Please shed more light on this decision as it comes to light.
I have a 2021 Yukon Denali XL with the Duramax & plan to trade & upgrade as soon as the new engine is incorporated.
Thanks.
I am thinking they had a lot of the earlier 3 liter diesels version diesels already built and would prefer to put the new engines in trucks who would probably do more towing or hauling than soccer moms in a Tahoe or Yukon.
Will GM offer the LM0 in the Yukon AT4 or Tahoe Z71? I have owned a 2021 Sierra AT4 with the LM2 for 17 months and put over 80k miles on it. With the LM2 over the 5.3 I’ve had in the past. I went from filling up every other day, to once a week , on avg I get 26 MPG, with 33’ tires and leveling kit. I love these 3.0L Duramax engines. Please put the LMO in the Yukon AT4 and Tahoe Z71 !!!
Well folks, stay tuned for tomorrow’s edition when you’ll see them tell essentially the exact same story, for the third day in a row, but this time it’ll say Escalade instead of Yukon or Tahoe / Suburban. Sometimes I wonder if they’re a little desperate for story material…
sometimes they delete the story and repost it again so its pushed to the top of the page. keep an eye. its comical
This is BS. No excuse for GM continuing to delay better product that everyone knows has been ready to go for way too long now. Postponing my order until when, now??
until they stop milking the existing stuff for 85k msrp thats when. people keep buying so why should gm update anything. they are laughin and calculating their bonuses
Disappointment after disappointment for future Tahoe/Yukon buyers.
So when will the 2025 Yukon be available to order with the LZO?? Recently had to cancel order since finding out that the LZO wont be offered in the 2024 models. Just stop using the underpowered LM2 for the Yukon like you have with the 1500 series trucks. Stick the LM2 in the Canyons/Colorados, would be a great place to put that motor.
