The Mercury Mariner is a Ford Escape with more stylish appointments and only minor differences equipment. Mariner offers a combination of nimble handling, comfortable ride, and an optional 3.0L V-6 for decent performance. The Mariner also offers a hybrid powertrain model. By alternately running off batteries and the gasoline engine, the Mariner Hybrid boasts a 36 mpg rating in city driving.

The 2008 Mariner features updated styling inside and out. The most notable changes are to the front and rear fascias. Most notably, the front end features a larger waterfall-style grille and more prominent powerdome on the hood. Outside of a new electric power steering system, the chassis and powertrains are largely the same.
