Active Fuel Management is an exciting Holden technology that is available on all V8 Caprice, Commodore, Sportwagon and Ute models with automatic transmission.
Active Fuel Management (AFM), available on all Holden V8 (automatic transmission) models is an exciting Holden technology that temporarily de-activates four of the eight engine cylinders in certain driving conditions when less engine power is required.
Most V8 cars have more power than owners demand in all conditions. With AFM, owners can save fuel. The Gen IV 6.0L (L76) engine saves fuel by using only half of the V8 engine's cylinders and seamlessly reactivating the other cylinders when you need additional power for acceleration or load.
If you often travel long distances at steady speeds you can expect lower operating costs and fuel-efficiency improvements. You can look forward to gains of up to 1.0 Litre per 100km and potentially more in certain driving conditions. And you can still experience the outstanding power of the Gen IV 6.0L V8 engine when you need it.
It's not just fuel that you're conserving. Active Fuel Management reduces Greenhouse Gas emissions to the same extent as it reduces fuel consumption.
The engine's Electronic Throttle Control (ETC) is used to balance torque following cylinder deactivation or reactivation. All cylinders are reactivated when you require acceleration or full torque, the transition takes less than 20 milliseconds and is virtually impossible to detect as you drive.
Managed by the sophisticated E38 engine control module (ECM), AFM automatically shuts down every second cylinder of the engine, according to firing order, during certain light load conditions. It makes use of the engine's existing capabilities. The only mechanical components required are special valve lifters for cylinders that are deactivated, and their control system.
