The 2024 Chevy Tahoe and 2024 Chevy Suburban are set to introduce full model refreshes complete with a long list of updates and changes. Among these changes is the likely introduction of the new 3.0L I6 LZ0 turbodiesel Duramax engine as a replacement for the current full-sizer’s 3.0L I6 LM2 turbodiesel Duramax engine. Which leads us to ask – will the 2024 Chevy Tahoe Z71 and 2024 Chevy Suburban Z71 finally offer diesel power?
For those readers who may be unaware, the off-road-oriented Chevy Tahoe Z71 and Chevy Suburban Z71 are currently offered exclusively with gasoline powerplants, namely the naturally aspirated 5.3L V8 L84 gasoline engine, rated at 355 horsepower at 5,600 rpm and 383 pound-feet of torque at 4,100 rpm, and the naturally aspirated 6.2L V8 L87 gasoline engine, rated at 420 horsepower at 5,600 rpm and 460 pound-feet of torque at 4,100 rpm. Elsewhere in the lineup, both the Tahoe and the Suburban offer the 3.0L I6 LM2 diesel engine as well.
As GM Authority was the first to report, the Z71 trim levels for both nameplates do not offer the option for diesel power due to their unique front fascia treatment, which obstructs the intercooler and associated piping.
Now, however, with the introduction of the LZ0 engine for the upcoming 2024-model-year refresh, perhaps that will change. After all, the 2024 Chevy Silverado ZR2 will offer the new 3.0L I6 LZ0 diesel engine, and given the ZR2’s more-aggressive front fascia treatment, perhaps GM will find a way to squeeze the LZ0 under the hood of the 2024 Chevy Tahoe Z71 and 2024 Chevy Suburban Z71 as well.
Of course, that’s just speculation at this point, but the engine would certainly enhance the off-roaders’ prowess in the rough stuff. As a reminder, the 3.0L I6 LZ0 diesel engine is rated at 305 horsepower at 3,750 rpm and 495 pound-feet of torque, and all that low-end twist will surely be appreciated in the two Z71 full-size SUV models.

That will be a game changes for GM and the Tahoe. That low end Torque will be a huge boost to the Z71 Tahoe, one that is much needed on slow off road trails and to also better compete with the Sequoia TRD off road series. Everyone I have talked with and most social media channels think this is a big shortcoming in the current Z71 offering. If they are doing a major refresh and changing the front fascia, then they should find a way to re-design the front to make room for the intercooler. I will order one day 1.
Why stop there they need ZR2 models as well.
This is the combo I wanted in 2022. Ended up with the RST with a duramax. It’s been fantastic. I would trade for a duramax z71 if it were offered. A ZR2 suburban would blow my mind.
If this happens, it would be great. Diesel is the safest, longest lasting, most durable power plant.
Hope it happens. My letter of purchase intent is submitted for a 2024 Suburban in white.
I have as of this Saturday morning 552,581.7 miles on the meter on my 1998 GMC Suburban 2500. Original all except for a couple of fuel pumps and starters.
My only wish is that the GM dealer here in Durango, Colorado, Morehart-Murphy Motors would change their service policy to work on GM vehicles that are 10 or more years old.
How is the diesel the safest and longest lasting? It’s the only engine currently in production that must be removed for servicing (@150k miles per the lm2 and 200K per the LZ0) smallblocks are half a million mile engines with only oil changes required.
Oh your Ignorance is noted.
None of this modern small block V8 can go 500k miles without serious engine work. The intake valves will gunk up from direct injection, the cam/lifters will fail from AFM and the cylinder walls will deform overtime from having some cylinders off and some off.
Then again buy one yourself and run it to 500k miles before preaching.
