Does the MDX have VCM?
Yes, the Acura MDX does have a Variable Cylinder Management (VCM) system. VCM is a fuel-saving technology that allows the engine to operate on fewer cylinders when full power is not needed, improving fuel efficiency.
What is Variable Cylinder Management (VCM)?
Variable Cylinder Management (VCM) is an engine technology that allows an engine to operate on fewer cylinders when full power is not required, such as during cruising or light-load conditions. This helps improve fuel efficiency by reducing the engine's workload and the amount of fuel consumed.
In a VCM-equipped engine, the engine control unit (ECU) continuously monitors driving conditions and adjusts the number of active cylinders accordingly. When full power is needed, such as during acceleration or towing, all cylinders are activated. But when less power is required, such as during steady-state cruising, some cylinders are deactivated to reduce fuel consumption.
VCM in the Acura MDX
The Acura MDX, a popular midsize luxury SUV, is equipped with a VCM system. Specifically, the MDX's 3.5-liter V6 engine features VCM, which allows it to operate on 3, 4, or 6 cylinders depending on driving conditions.
When the MDX is cruising at a steady speed or under light loads, the VCM system can deactivate up to 3 of the engine's 6 cylinders, improving fuel efficiency. But when more power is needed, such as for acceleration or towing, the VCM system reactivates all 6 cylinders to provide the necessary performance.
The VCM system in the MDX is designed to be seamless and unnoticeable to the driver, with no perceptible changes in engine operation or performance. This allows the MDX to deliver a balance of power and efficiency, making it a popular choice among midsize luxury SUV buyers.
