What Year Did Gm Start Using Afm?

In 2005, General Motors (GM) adopted its Active Fuel Management (AFM) system for the first time. The goal of AFM technology is to increase the fuel efficiency of current engines and decrease carbon emissions from vehicles.

When full power is not required, the cylinders in the engine are deactivated via the AFM system. This minimizes the amount of fuel required to be burned and improves the engine’s performance. The system is designed to return to maximum power when the driver requests more power.

Since 2005, GM has utilized AFM technology and has since improved the system’s efficiency and dependability. GM has also deployed the technique in other vehicles, including as cars, trucks, and SUVs, in an effort to further improve fuel economy.

The AFM system is one of the numerous efforts General Motors has made to make its vehicles more energy efficient and lower pollution. GM has adopted a number of additional fuel-saving technology, such as engine start/stop systems and direct fuel injection, to increase fuel efficiency.

Since 2005, GM has utilized AFM cylinder deactivation technology to increase the fuel economy of their vehicles. The system has been used in a range of GM vehicles and has been continuously updated and enhanced over the years.


Cars were and will be my first love and favorite hobby; I decided to start writing about my discoveries and techniques to improve my cars or repair them.
