Active Cylinder Control
DaimlerChrysler's Active Cylinder Control (ACC) is a variable displacement technology. It debuted in 1999 on the 6.0 L V12 in the CL600 and S600 and 5.0 L V8 in the CL500. Like Chrysler's later Multi-Displacement System, General Motors' Displacement on Demand and Honda's Variable Cylinder Management, it deactivates one bank of the engine's cylinders when the throttle is closed.
In order to preserve the sound of the engines, DaimlerChrysler worked with Eberspaecher to design a special exhaust system for ACC-equipped vehicles. The system uses an active valve to divert exhaust between two different exhaust systems. It also has a variable length intake manifold system to optimize output in the two modes.
