The Suburban's Active Fuel Management System improves fuel economy by 10%
The 2007 Chevrolet Suburban is a powerful truck with a standard V8 5.3-liter engine and an optional V8 6.0-liter engine. The 5.3-liter engine produces 320 horsepower with 340 pound-feet of torque, while the 6.0-liter engine generates 366 horsepower and 380 pound-feet of torque.
One notable feature of the 2007 Suburban is its Active Fuel Management System (AFM), also known as Displacement on Demand (DOD) or 4-cylinder mode. This system was introduced by General Motors (GM) in 2005 to improve fuel economy in some of their larger engine applications. The Suburban has a reputation for being a gas-guzzler, and the AFM system aims to address this issue.
The AFM system works by automatically switching from using eight cylinders to using four cylinders when the engine's full power is not required. This conversion effectively makes the V8 engine operate more like a fuel-efficient V4, reducing fuel consumption. The system is designed to activate during low-power conditions, such as when the vehicle is coasting downhill, slowing down, or cruising at lower speeds.
According to Chevrolet, the AFM system in the 2007 Suburban improves fuel economy by about 10%. This equates to approximately 1 mile per gallon (mpg) of savings. While some reviewers have noticed improvements in fuel efficiency, others have experienced issues with the system. Some owners have reported that the AFM system does not always engage as expected, particularly when driving at highway speeds or on level surfaces. There have also been reports of rough transitions between V8 and V4 modes, although software updates have been released to address this issue.
Overall, the Active Fuel Management System in the 2007 Chevrolet Suburban is designed to enhance fuel efficiency and provide a more economical driving experience, especially during everyday driving conditions when the full power of the V8 engine is not necessary.
