As Mercury refines its image, it also is refining the Mountaineer, with revisions throughout. The 2006 model has a revised front fascia, fog lamps, and trim. Updates continue down the side with more aerodynamic mirrors and integrated power running boards. To the rear, clear taillamp lenses and new liftgate round out the cosmetic makeover. More drastic changes were made to the interior, with new seats, instrument panel, and upgraded materials. Changes in the seats create a flatter load floor, and the second row will be available with captains-style configuration. The powertrain has been enhanced, with a more-potent three-valve 4.6L V-8 now producing 292 horsepower and 300 lb-ft of torque, round through a six-speed automatic transmission. An improved 4.0L V-6 with five-speed automatic remains standard equipment. All these components ride on a strengthened platform damped by a revised suspension, with an all-new independent rear setup. This comprehensive roster of tangible improvements promise to put Mercury on track as an American luxury nameplate for the 21st century.
