Line 1:

[[Chrysler]]'s '''Multi-Displacement System''' ('''MDS''') is an [[automobile]] engine [[variable displacement]] technology. It debuted in 2006 on the 5.7 L [[Chrysler Hemi engine|modern Hemi]] [[V8 engine|V8]]. Like [[Mercedes-Benz]]'s [[Active Cylinder Control]], [[General Motors Corporation|General Motors]]' [[Active Fuel Management]], and [[Honda]]'s [[Variable Cylinder Management]], it deactivates four of the V8's cylinders when the throttle is closed or at steady speeds.

It is complete junk, and ruins the reliability of the engine.

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 was offered on all seven models, including SUVs and 1500 series trucks, using the 5.7 L engine.
