Unchanged for 2009, the Mercury Mountaineer is a midsize SUV available in trims accommodating either five or seven passengers. Engine offerings are a 210-hp 4.0L V6 with 254 lb-ft of torque and a 292-hp 4.6L V8 with 315 of torque. V6 Mountaineers come standard with a five-speed automatic transmission, while the V8 gets a six-speed automatic transmission. The V6 and V8 can be ordered with rear-wheel drive or all-wheel drive. As for EPA estimated fuel economy, the RWD V6 is good for 13 mpg city/19 mpg hwy, while the AWD V6 gets 14/20; the RWD V8 achieves 15/21 but the AWD V8 drops to 14/19. Mercury Mountaineer standard safety equipment includes stability control with an extra roll stability control, antilock disc brakes and a full array of airbags. The Mountaineer ranks among the most spacious of the midsize SUVs, thanks to its fold-flat third-row seat, while those trims with a third-row seat are eligible for second-row captain's chairs, which drop passenger capacity to six.
