On 23 May 2013, Ford Australia announced the end of its local manufacturing operations (involving Falcon and Territory models) by October 2016, with the Falcon nameplate destined to retire after 56 years of continuous production in Australia. A high manufacturing cost base (with costs at the Campbellfield plant some four times higher than in Ford's Asian plants and twice as much as in Europe) and unsustainable low sales of its Australian-made products were factors in Ford Motor Company's decision to end its Australian manufacturing activities after 90 years. The announcement put an end to years of speculation concerning the Falcon's future, which included the possibility of the Falcon switching from its current Australia-only architecture to a global large car platform to be built for all world markets as part of the "One Ford" global product development plan implemented in 2006. The options consisted of either a rear-wheel-drive platform (shared with Mustang) or a transverse front-wheel-drive platform (shared with Explorer and Taurus). Ultimately, it was decided by Ford that the Ford Mustang coupé would be the only rear-wheel drive Ford car built for all global markets and that the Falcon nameplate would be retired.
