These two engines were already under constraint on the refreshed 2022 Chevy Silverado 1500, as GM Authority reported previously, but it was unclear if they would return to the pickup before production shifted over to the 2023MY. We have now learned these engines will be under constraint for the remainder of the 2022MY production run, leaving only the turbocharged 2.7L L3B gasoline engine and the 5.3L L84 V8 gasoline engine unaffected by supply setbacks. To be clear, the LM2 diesel engine is not available to order in the Silverado Custom Trail Boss, LTZ, and High Country trim levels only.
Customers waiting for their new 2022 Chevy Silverado 1500 to be built with one of these two unavailable engines will likely be contacted by their dealer to propose alternative solutions. These solutions may include delaying production of the customer’s new truck, or selecting one of the two available alternative engine options.
The 2023 Chevy Silverado 1500 will replace the 3.0L LM2 diesel engine with a mildly updated model referred to as LZ0. While it’s not clear how the LM2 and LZ0 will differ, it seems likely the newer version will offer improved emissions and fuel economy figures, or potentially an increase in output and capacities. That means all Chevy Silverado 1500 models featuring the LM2 engine have now been produced. The L3B engine is rated at 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm.
Production of the 2023 model year Chevy Silverado 1500 will continue to take place at the GM Silao plant in Mexico, GM Fort Wayne plant in Indiana, and GM Oshawa plant in Canada. Details on pricing and when production of the 2023 model year Silverado 1500 will commence are currently not available.
