{{Short description|Chrysler automobile technology}}

[[Chrysler]]'s '''Multi-Displacement System''' ('''MDS''') is an [[automobile]] engine [[variable displacement]] technology. It debuted in 20062005 on the 5.7 L [[Chrysler Hemi engine#Third generation: 2003-present|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.

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 SUV'sSUVs and 1500 series trucks, using the 5.7 L engine.

Chrysler expected that the technology would boost economy by 10% to 20%. In the [[Jeep Grand Cherokee]] with MDS, highway fuel mileage for the V8 is the same as the V6 at 21 mpg (11.2 liters per 100 km).
