[[Chrysler]]'s '''Multi-Displacement System''' (MDS) is an [[automobile]] engine [[variable displacement]] technology. It debuted in [[2004]] on the 5.7 L [[Chrysler Hemi engine|modern Hemi]] [[V8]]. Like [[Mercedes-Benz]]'s [[Active Cylinder Control]], [[General Motors Corporation|General Motors]]' [[DisplacementActive onFuel DemandManagement]], and [[Honda]]'s [[Variable Cylinder Management]], it deactivates four of the V8's cylinders when the throttle is closed.

The system was first offered only on passenger cars, since the heavy demands of trucks would interfere with its operation. However, it was recalibrated for [[2006]] and will be offered on all seven models, including trucks, using the 5.7 L engine.
