Fact of the Week

Fact #725: Cylinder deactivation is a fuel-saving technology that allows a vehicle to shut down some of its cylinders when extra power is not needed like when cruising down the highway at a constant speed. The cylinders can be activated under heavy load situations like towing or acceleration where more power is required. This technology is particularly well suited to light trucks where the power requirements for hauling, towing and cruising vary greatly. In model year 2011, 38% of pickup trucks and 17% of vans and SUVs had engines with cylinder deactivation.
