According to a recent GM presentation during the 2021 Work Truck Show, the naturally aspirated 4.3L V6 LV3 gasoline engine and naturally aspirated 5.3L V8 L82 gasoline engine will be dropped from the Chevy Silverado 1500 and GMC Sierra 1500 lineup for the 2022 model year.
GM Authority was the first to question the longterm prospects for the 4.3L V6 LV3. Back in December, we compared the LV3 to the turbocharged 2.7L I4 L3B gasoline engine, illustrating how the four-cylinder L3B bests the V6 LV3 in a variety of metrics, including power, torque, fuel efficiency, max trailering, payload, and 0-to-60 mph acceleration. While the transmissions used with each powerplant (eight-speed automatic for the L3B and six-speed automatic for the LV3) play a role here, there’s no question that the turbocharged engine and high-tech valvetrain are the defining factor.
More information on the engine changes can be found in the graphics below:
As a reminder, the naturally aspirated 4.3L V6 LV3 is rated at 285 horsepower at 5,300 rpm and 305 pound-feet of torque at 3,900 rpm, while the naturally aspirated 5.3L V8 L82 is rated at 355 horsepower at 5,600 rpm and 383 pound-feet of torque at 4,100 rpm.
Meanwhile, the turbocharged 2.7L I4 L3B is rated at 310 horsepower and 348 pound-feet of torque. Other options include the naturally aspirated 5.3L V8 L84, which, like the L82, produces 355 horsepower and 383 pound-feet of torque. However, the L84 features Dynamic Fuel Management, as opposed to the L82’s Active Fuel Management.
The rest of the Chevy Silverado 1500 and GMC Sierra 1500 powerplant lineup includes the naturally aspirated 6.2L V8 L87, which is rated at 420 horsepower and 460 pound-feet of torque, and the 3.0L I6 LM2 turbodiesel Duramax, which is rated at 277 horsepower and 460 pound-feet of torque.
