The fully refreshed 2022 GMC Sierra 1500 introduces a long list of updates and changes over the pre-refresh 2022 GMC Sierra 1500 Limited and 2021 GMC Sierra 1500. Unfortunately, the 2022 GMC Sierra 1500 is currently under constraint with regard to the naturally aspirated 6.2L V8 L87 gasoline engine and 3.0L I6 LM2 turbodiesel Duramax engine, a condition that GM Authority has learned will remain in effect through the remainder of the 2022 model year.
Earlier this month, GM Authority was the first to report that the naturally aspirated 6.2L V8 L87 gasoline engine in the 2022 GMC Sierra 1500 was under constraint and unavailable to order. Additionally, GM Authority recently reported that the 2022 Chevy Silverado 1500 is also currently under constraint with regard to the 6.2L V8 L87 gasoline engine and 3.0L I6 LM2 Duramax engine, a condition that is expected to remain in place for the rest of the 2022 model year.
The naturally aspirated 6.2L V8 L87 gasoline engine is rated at 420 horsepower at 5,600 rpm and 460 pound-feet of torque at 4,100 rpm, while the 3.0L I6 LM2 turbodiesel Duramax is rated at 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm. Going forward, GM Authority has learned that the upcoming 2023 GMC Sierra 1500 Duramax will cradle the new 3.0L I6 LZ0 turbodiesel engine, with the new LZ0 replacing the LM2 in the light-duty GMC Sierra lineup as the “second iteration” of the Duramax 3.0L six-cylinder.
As for 2022 model-year vehicles, customers waiting for their new 2022 GMC Sierra 1500 to be built with one of the two unavailable engines will likely be contacted by their dealer with alternative solutions, including delayed production of the new truck, or selection of one of the two available alternative engines.
The other two engine options in the 2022 GMC Sierra 1500 lineup include the turbocharged 2.7L I4 L3B gasoline engine, rated at 310 horsepower and 430 pound-feet of torque, and the naturally aspirated 5.3L V8 L84 gasoline engine, rated at 355 horsepower and 383 pound-feet of torque. Under the skin, the 2022 GMC Sierra 1500 rides on the GM T1 platform, with production taking place at the GM Fort Wayne plant in Indiana and GM Silao plant in Mexico.
