General Motors is starting to build light-duty Chevy Silverado 1500 and GMC Sierra 1500 pickup trucks without Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) technologies as a result of the ongoing global microchip shortage. Now, GM Authority has learned that GM will offer a small credit on every impacted vehicle.
In an email exchange with GM Authority, Communications Manager, Chevrolet Trucks and Full-Size SUVs, Megan Soule, confirmed that General Motors will offer a credit of $50 MSRP on every VIN impacted by the change.
As GM Authority covered previously, some 2021 Chevy Silverado 1500 and 2021 GMC Sierra 1500 models equipped with the naturally aspirated 5.3L V8 L82 gasoline engine and naturally aspirated 5.3L V8 L84 gasoline engine will no longer feature Active Fuel Management and Dynamic Fuel Management due to the ongoing microchip shortage.
Active Fuel Management deactivates half of the engine cylinder banks under light drive conditions, thus improving fuel mileage. Meanwhile, Dynamic Fuel Management also deactivates cylinders for improved fuel economy, with up to 17 different cylinder activation patterns for optimum efficiency and power delivery.
According to GM spokeswoman Michelle Malcho, the omission of AFM and DFM technologies on 2021 Chevy Silverado 1500 and 2021 GMC Sierra 1500 models is expected to lower fuel economy by about 1 mpg. Malcho added that GM will continue to build light-duty pickups without the fuel-saving tech, but did not specify the volume of vehicles expected to omit AFM and DFM. That said, the change is expected to be in place for the remainder of the 2021 model year.
So far, the microchip shortage has reduced availability of various vehicle options, including those for GM’s popular full-size SUVs. It’s estimated that the shortage will result in nearly 60,000 vehicles to be cut from GM’s North America production schedule.
