The General’s full-size SUV lineup is available with a variety of different engines, including gasoline and diesel options. More specifically, the 2024-model-year GM SUVs offer the 3.0L I6 LM2 turbodiesel Duramax, providing solid torque figures alongside impressive fuel economy. That said, the LM2 is set to depart with the launch of the 2025 model year, and now, today is the last day to order the Duramax engine in the 2024-model-year full-size models.
As for the nameplates affected, the 2024 Chevy Tahoe, 2024 Chevy Suburban, 2024 GMC Yukon, and 2024 Cadillac Escalade will all no longer be available to order with the optional 3.0L I6 LM2 turbodiesel engine after today.
The 3.0L I6 LM2 turbodiesel is rated at 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm. Introduced to General Motors’ full-size SUV lineup in conjunction with the 2021 model year, the LM2 mates to the GM 10-speed automatic transmission.
Looking ahead, production of the LM2 will end in September. In its stead, the refreshed 2025 Chevy Tahoe and refreshed 2025 Chevy Suburban will both offer the new 3.0L I6 LZ0 turbodiesel engine, which produces more output than the outgoing LM2 (305 horsepower and 495 pound-feet of torque), while bringing several other advantages as well. The new LZ0 will have late availability for the refreshed 2025 Tahoe and Suburban, and will not be available at the start of regular production. In addition to the new diesel power plant, the refreshed Tahoe and Suburban will also offer the gasoline-powered 5.3L V8 L84 and 6.2L V8 L87, as was the case previously.
Meanwhile, the refreshed 2025 Cadillac Escalade will no longer offer a diesel engine option due to a lack of demand. As GM Authority covered previously, the take-rate on diesel-powered Escalade models was around five percent. As such, non-V-variants of the Escalade will be equipped exclusively with the naturally aspirated 6.2L V8 L87 gasoline engine.
All full-size General Motors SUVs ride on the GM T1 platform, and every unit is produced at the GM Arlington plant in Texas.

but why
a better version of the diesel is coming lol. why would anyone want to order this one. strange post guys
Late availability would be the one reason I see.
So after the usual pushbacks, you’ll be able to order it by mid year 2030.
fomo only works if you believe it.
GM says there was lack of demand, but the real reason was lack of PROMOTION ! Both from GM and the dealer networks. Don’t understand why the new one has to be late availability either, seems that GM is finding more ways than ever, to not get their $hit together!
The 3.0 was on constraint and there were only 40 orders nationally this week. I was given one of the constraints but passed due to the new diesel for 25.
I had a 1500 pickup with the 3.0 diesel . Had to trade it off to go up to a 2500 due to Ranch activities. I highly recommend this engine for highway driving. Averaged 26 mpg.
I have a 2020 Silverado with the 3L diesel. I don't tow, but I use this truck extensively for long range trips. The engine/transmission must have come from an UFO because the MPG numbers I get are ridiculous. I get 24-26mpg driving through my regular commute through downtown Orlando without ever going on the highway. Highway driving I regularly exceed the 33mpg listed. It's crazy that I get far better city and highway mileage than my wife's mid size SUV with a four cylinder. I love the LM2.
