Boss is the internal name for a family of large-displacement V8 engines from Ford Motor Company intended to compete with Chrysler's Hemi and General Motors' 6.0 L Vortec engines. Originally named Hurricane, development of the engine was cancelled in 2005, then revived in early 2006 by Mark Fields[1] In light of the devastation caused by Hurricane Katrina in 2005, it was renamed the Boss engine.[1] In spite of this change, Ford did not officially market the engines with the Boss name in any production vehicle where they were used, instead referring to the engines by their displacement.
The first (and ultimately only) modern Boss engine, a 6.2 L V8, was produced at the Ford Romeo Engine Plant in Romeo, Michigan, from 2010 to the plant's closure in December 2022.[2]
Ford Australia and Ford Performance Vehicles used the "Boss" name for V8 engines from 2002, but these were variations of the Ford Modular V8 with locally produced parts.
