Does the 2010 Challenger RT have MDS?
In brief: the 2010 Challenger R/T includes Multi-Displacement System (MDS) only when equipped with the automatic transmission; the six-speed manual version does not support MDS.
Understanding MDS in the Challenger RT
MDS, or Multi-Displacement System, is Chrysler's cylinder deactivation technology. On the 5.7-liter Hemi V8 used in the Challenger R/T, MDS can deactivate four of the eight cylinders to improve highway fuel economy during light-load cruising. The system is managed by the engine computer and is designed to be transparent to drivers, engaging and disengaging as needed.
Which transmissions apply to the 2010 Challenger RT?
In 2010, the Challenger R/T was offered with two transmissions for the 5.7-liter Hemi: a five‑speed automatic that supports MDS and a six‑speed manual that does not. The MDS capability is tied to the automatic transmission; manual-equipped cars do not use cylinder deactivation.
Before listing key facts, here's a quick summary of the practical implications:
- Automatic R/Ts with the 5.7L Hemi use MDS to improve fuel economy by independently deactivating four cylinders during light loads.
- Six-speed manual R/Ts do not use MDS; all eight cylinders fire under typical driving conditions.
- Activation is automatic and depends on vehicle speed, engine load, and RPM; you typically won't notice it during heavy acceleration or spirited driving.
- In some cruising conditions, drivers may hear or feel the engine transition between 4- and 8-cylinder operation, but modern systems are designed to minimize noticeable changes.
Conclusion: If you want MDS on a 2010 Challenger RT, you need the automatic transmission; the manual version won't have it.
