The Ford Flex is a full-size crossover SUV or wagon that was manufactured by the Ford Motor Company; a single generation was produced from the 2009 to 2019 model years. Introduced as the successor to the Ford Taurus X, the model line also functionally replaced the Ford Freestar minivan. Slightly larger than its predecessor, the Flex was sized between the Explorer and standard-wheelbase Expedition in the Ford model line. Introduced in 2005 as a concept vehicle, the Flex shifted body configurations from an MPV to a 5-door wagon for production to better meet consumer demand. The model line is based on the Ford D4 chassis architecture, a flexible-wheelbase variant of the Ford D3 platform. The D4 chassis was also shared by the 2011-2019 Explorer and the Lincoln MKT; while sharing no body panels, the MKT served as a direct counterpart of the Flex. From June 2008 until its withdrawal, the Ford Flex was manufactured by Ford Canada at Oakville Assembly (Oakville, Ontario); the Flex and the Lincoln MKT were produced alongside the Ford Edge and Lincoln MKX (today, Lincoln Nautilus). The Flex was marketed in the United States, Canada, and the Middle East.
