2009 Mercury Mariner Hybrid

The 2009 Mercury Mariner Hybrid uses a new 2.5-liter inline 4-cylinder engine designed to run on the Atkinson combustion cycle combined with an electric motor and a new engine processor for smooth transitions between gas and electric mode. A new powertrain damping system reduces vibration and feedback to the occupants. The braking system has been refined for a seamless transition between regenerative braking and standard brake functionality.
