The 2019 Chevrolet Silverado 1500 comes with a new six-cylinder engine option. This is the first time that Chevy has offered a six-cylinder engine in the Silverado since 1998. The new engine is called the EcoTec3 6.2L V8 and it features cylinder deactivation technology.
This means that when you don’t need all eight cylinders, the engine will shut down four of them to save fuel.
The 2020 Silverado 1500 has cylinder deactivation, which improves fuel economy by up to 8 percent. This feature shuts off half of the engine’s cylinders when they’re not needed, such as when cruising on the highway. When more power is needed, all cylinders are activated automatically.
The system constantly monitors driving conditions and seamlessly transitions between modes without any driver input.
Chevy Cylinder Deactivation Years
Since the early 2000s, Chevrolet has used cylinder deactivation technology in some of its engines. This system allows the engine to operate on fewer cylinders when full power is not needed, such as during highway cruising. Cylinder deactivation can improve fuel economy by up to 10 percent.
Chevrolet first introduced cylinder deactivation in 2004 with the 5.3-liter V8 engine in the Silverado and Suburban. This system, called Active Fuel Management (AFM), could operate on either four or eight cylinders depending on driving conditions. AFM was expanded to additional models and engines over the years, including the 6.0-liter V8 in 2007 and the 4.3-liter V6 in 2013.
The latest version of cylinder deactivation is available on certain 2020 Chevy models equipped with a 5.3-liter V8 engine. This system, which GM calls Dynamic Fuel Management (DFM), can shut down anywhere from one to seven cylinders depending on need. DFM is capable of operating on two cylinders at highway speeds, which helps improve fuel economy even further compared to previous versions of AFM.
