Yes, the Acura MDX has cylinder deactivation. The Variable Cylinder Management (VCM) system in the Acura MDX switches between 6-cylinder operation and 3-cylinder operation, depending on driving conditions. When high output is required, the engine runs on full V-6 power, but during steady cruising, the engine switches to three cylinders to improve highway fuel efficiency.
Please note that the 3.0L V6 MDX Sport Hybrid does not have VCM and operates differently from the non-hybrid version.
