wheels, satin-silver trim for the sideview mirrors and bumpers; the grille and tailgate received larger Mercury emblems. Following the discontinuation of the Lincoln Aviator, the Mountaineer again served as the premium mid-size SUV offering of the Lincoln-Mercury division. To better differentiate the model line from the Explorer Eddie Bauer and Limited, Lincoln-Mercury upgraded the interior trim of the Mountaineer and carried over various features from the discontinued Aviator, including the option of a DVD-based navigation system with voice control (not offered on any Explorer until 2008). As an option, the Mountaineer Premier offered power-retracting running boards (a feature adopted from the larger Lincoln Navigator, not introduced on the Explorer until 2007). The Mountaineer carried over the 210 hp 4.0L SOHC V6 as the standard engine, introducing a 292 hp 4.6L Modular 24-valve V8 as an option (replacing the previous 16-valve version). V6 engines were paired with a 5-speed 5R55W automatic transmission; V8 engines received an all-new 6R 6-speed automatic. During its production, the third-generation Mountaineer saw relatively few functional changes. For 2007, "MOUNTAINEER" badging was returned to the doors (after a four-year absence). For 2008, side-curtain airbags were made standard. For 2009, trailer-sway control was made standard on examples equipped for towing. The navigation system was upgraded, including traffic flow monitoring and live updates on fuel prices from nearby service stations. For 2010, all trim levels received the Ford MyKey system as a standard feature; the system is a programmable security system designed for vehicles owned by multiple drivers. Discontinuation For 2000, the Mountaineer was the third-best-selling Mercury (behind the Sable and Grand Marquis); ten years later, the model line had become the slowest-selling vehicle of the brand. Following the June 2010 announcement by Ford Motor Company to shelve the Mercury brand, 2010 would be the end of Mountaineer production; the final vehicle was produced on October 1, 2010. Unlike the Milan, Mariner, and Grand Marquis, the Mountaineer was not produced for a short 2011 model year. While the Ford Fusion and Ford Escape has seen only detail changes for 2011 (the Ford Crown Victoria had already ended retail sales in North America), the Ford Explorer underwent a major redesign for 2011; along with several major changes to the model line, the Explorer no longer shared a body with any divisional counterparts. Since 2020 production, Lincoln has marketed a revived Lincoln Aviator. Though again based on the Ford Explorer, the
