The Mountaineer is offered in two trim levels, Base and Premier, and is available in both rear-wheel and all-wheel drive configurations. Two powertrain combinations are available: a 210-hp 4.0-liter V6 mated to a five-speed automatic transmission, or a 292-hp 4.6-liter V8 paired with a six-speed automatic. Mountaineer Base trims are well-equipped with 17-inch alloy wheels, automatic headlamps and air conditioning; Premier trims add 18-inch chrome-clad wheels, leather and simulated suede upholstery, automatic climate control, SYNC communication system and a third-row seat. Standard safety features include AdvanceTrac electronic stability control with anti-rollover technology, traction control and anti-lock disc brakes, as well as front, side-impact and side-curtain airbags. For 2009, the Mercury Mountaineer carries over with minimal changes, including revised option packages and the addition of standard satellite radio on Premier trims. A new VOGA package is also available for the Premier, offering chrome exterior accents, exclusive interior trim elements and unique leather upholstery.
