Last September, General Motors revealed the fully refreshed 2022 Chevy Silverado 1500, ushering in a variety of changes and updates as compared to the 2021 model year and pre-refresh 2022 Chevy Silverado 1500 Limited. One of the powertrain changes for the 2022 Chevy Silverado 1500 refresh was a healthy torque boost for the turbocharged 2.7L I4 L3B gasoline engine, which at the time of the announcement, was uprated to 420 pound-feet of torque at 3,000 rpm. Now, however, General Motors has officially bumped the high-output L3B’s torque rating to 430 pound-feet.
Readers might recall that GM Authority was first to report back in December 2021 that the turbocharged 2.7L I4 L3B gasoline engine in the refreshed 2022 Chevy Silverado 1500 would be an SAE-certified at 430 pound-feet, rather than the 420 pound-feet of torque announced previously. Now, GM’s official peak torque figure has increased to 430 pound-feet of torque, a 10-pound-feet bump compared to the original figure announced with the debut of the 2022 Chevy Silverado 1500 refresh.
Prior to the 2022 model year refresh, the turbocharged 2.7L I4 L3B gasoline engine was rated at 310 horsepower at 5,600 rpm and 348 pound-feet of torque at 1,500 rpm. Moving forward, that horsepower rating remains unchanged at 310 ponies for both the pre-refresh models and refreshed models.
To note, the high-output L3B engine replaces the naturally aspirated 4.3L V6 LV3 gasoline engine and naturally aspirated 5.3L V8 L82 gasoline engine in the Silverado lineup, and is offered as the standard base engine for the refreshed 2022 Silverado 1500 WT, Custom, Custom Trail Boss, LT, RST, and LT Trail Boss trim levels.
In addition to the high output 2.7L L3B gasoline engine, the fully refreshed 2022 Chevy Silverado 1500 is also available with the naturally aspirated 5.3L V8 L84 gasoline engine, the naturally aspirated 6.2L V8 L87 gasoline engine, and the 3.0L I6 LM2 turbodiesel Duramax. Under the skin, the truck rides on the GM T1 platform, with production taking place at the GM Fort Wayne plant in Indiana, the GM Silao plant in Mexico, and the GM Oshawa plant in Canada.
