The 3.0L I6 LM2 turbodiesel Duramax engine is currently unavailable to order on the 2022 Chevy Silverado 1500 in the Custom Trail Boss, LTZ and High Country trim levels only, GM Authority has learned.
While it’s not clear why the 3.0L I6 LM2 engine is unavailable to order on the Silverado in these three trim levels, GM has been experiencing inventory issues with certain parts and components in recent months due to various global supply chain challenges. It’s unclear when, or if, it will return to these trim levels before production of the 2022 model-year Silverado concludes later this year.
The inline-six diesel engine is still available to order on the 2022 Chevy Silverado 1500 in the LT, RST and LT Trail Boss trim levels for the time being. As a reminder, this engine is rated at 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm and is paired with the GM 10-speed automatic transmission in the current Silverado 1500. Notably, this engine can return upwards of 31 mpg on the highway when under the hood of 2022 Chevy Silverado 1500 RWD models, as well as 23 mpg city and 26 mpg combined.
The mildly updated 2023 Chevy Silverado Duramax will introduce a new LZ0 iteration of the Duramax engine, which will carry similar specs as the LM2 turbodiesel. It’s unclear at this time exactly what the LZ0 will improve upon as compared to the current LM2 engine, but improved fuel economy, lower emissions, or an increase in output and capacities may be in store.
In addition to the 3.0L I6 LM2 turbodiesel Duramax, the refreshed 2022 Chevy Silverado 1500 is also available with the turbocharged 2.7L I4 L3B gasoline engine, naturally aspirated 5.3L V8 L84 gasoline engine, and naturally aspirated 6.2L V8 L87 gasoline engine. Production takes place at the GM Silao plant in Mexico, GM Fort Wayne plant in Indiana, and GM Oshawa plant in Canada.
