Mercury Mariner Hybrid Review
The Mercury Mariner and Ford Escape Hybrid are identical except for minor "badge engineering". 
The Mercury Mariner is virtually the same as the non-hybrid model except for two electric motors for propulsion when the gasoline engine isn't required and to start the engine. The hybrid system uses batteries and sophisticated software to combine the electric motors and gasoline motor making the hybrid drive like an ordinary Sport Utility Vehicle. The electric motors provide enough torque to propel the car up to 25 mile per hour. In city driving below 25 mph the Mercury Mariner Hybrid uses only batteries and makes virtually no noise and saves the most gas in this mode. The electric motors are powered by a 330-volt battery pack that's located under the Marinter's load floor. The battery pack is charged regeneratively, capturing energy during braking, and from the gas engine.

The Mercury Mariner SUV is a viable Sport Utility Vehicle that gets as advertised fuel savings with no compromises compared to the standard V-6 Model. There is a premium of about $3000 to be green, but there are tax rebates and incentives that may close the gap making it a non-issue.
