2009 Mercury Mariner

Reverse Sensing System
Although the Mariner is small and easy to maneuver in tight parking situations, this feature is still very helpful for peace of mind.

AdvanceTrac with Roll Stability Control
Other vehicles in its class offer a stability system, but the Mariner's AdvanceTrac uses a secondary roll-rate sensor, along with automatically and selectively applying the brakes and reducing engine power, to help reduce the chances of a roll-over.

Last year's redesign saw major improvements to the Mariner's interior and included new seats, door panels and a center console, as well as a floor-mounted shifter. Depending on the trim level, the seats are available in a monochromatic color scheme or two-toned with Alcantara suede inserts. The standard "top-of-dash" display, which shows radio, climate control readout and temperatures both inside and out, promotes safety and convenience by being positioned at eye level. The radio and climate controls are arranged in what Mercury calls the new "poke through" configuration; the buttons and knobs are raised rather than flush, replacing the "brick" design from the previous generation.

The 2009 Mercury Mariner benefits from last year's major redesign that included bolder front and rear fascias, new head and taillamps and a signature waterfall grille that has bigger spacing between the bars. The new roof panel has recessed channels that reduce noise in the cabin as well as horizontal ribbing that strengthens the chassis.

An all-new 2.5-liter four-cylinder engine employs variable valve timing to see an eleven percent increase in power and one mile per gallon improvement in fuel economy over last year's 2.3-liter engine. The larger 3.0-liter V6 is also improved, with a higher compression ratio that adds an additional 40 horsepower. The 3.0-liter provides better acceleration and the ability to tow up to 3,500 pounds, but its city fuel economy ratings only reach the high teens. Those looking for maximum fuel economy should opt for the hybrid powertrain, which uses the same all-new 2.5-liter four-cylinder engine mated to an electric motor. Unlike its Ford twin, the Mariner does not offer a manual transmission.
