Does the Chevy 6.6 have Active Fuel Management?
The Chevy 6.6 engine does not have Active Fuel Management (AFM). The AFM technology is present in various GM vehicles, including some Chevrolet models like the Camaro, Tahoe, TrailBlazer, Avalanche, Silverado, Suburban, and Impala. However, the 6.6L V-8 L8T gasoline engine for the 2020 Chevrolet Silverado HD and 2020 GMC Sierra HD is not equipped with Active Fuel Management (AFM).
