The base 2009 Mercury Mariner is powered by more potent propulsion options. Replacing a 2.3-liter engine, the 2.5-liter displacement powerplant found on the 2009 Mariner generates 175 horsepower and is matched with a six-speed automatic transmission. This engine was also added to the Mariner Hybrid. Peak power for the compact sport utility is showcased by a 240-horsepower V-6 engine. Introduced last year with the Mariner, a high-fashion VOGA styling package is expanded onto the Mercury Milan and Sable for 2009 consisting of a number of unique styling touches. For 2009, AdvanceTrac electronic stability control has been added as an option on the Mercury Milan while the Sable welcomes the technology as standard equipment. All 2009 model year Mercury Grand Marquis models come standard with leather seating and automatic load-leveling suspension.
