Launched between 2006 and 2020, the Ford Fusion went through a continuous development throughout two generations, with the first hybrid version introduced in 2010, while a plug-in variant, Fusion Energi entered production in 2013. First Ford Fusion was assembled on the CD3 platform, used by the Lincoln MKZ and Mercury Milan, whereas the second generation Ford Fusion switched to the global CD4 platform in line with the European Mondeo for better handling and rigidity. The standard powertrains comprised of the Duratec 2.3L and 2.5L I4, while enthusiasts got the Ford Fusion Sport (2017–2019), with a 2.7L EcoBoost V6 that churned 325 horsepowers. The transmission offered included 5-speed manuals and 6-speed automatics, in addition to hybrid models' eCVTs, catering for both economy and performance. New safety features introduced during it's lifetime included, Ford's SYNC multimedia system, rear parking assist and also available advanced features such as, lane-keeping assist and adaptive cruise control in models later in its life. Earlier versions had ABS and side airbags as optional while they became standard in the later production years. To maintain Ford Fusion's performance and safety, an owner should first prefer using authentic OEM Ford parts specifically engineered for perfect fitment and long-term reliability throughout all powertrain and safety systems to ensure that the vehicle maintains the exacting Ford quality standards.
