Active Cylinder Control (original) (raw)

Daimler AG's Active Cylinder Control (ACC) is a variable displacement technology. It debuted in 2001 on the 5.8 L V12 in the CL600 and S600. Like Chrysler's later Multi-Displacement System, General Motors' Active Fuel Management and Honda's Variable Cylinder Management, it deactivates one bank of the engine's cylinders when the throttle is closed.
